Roof base preparation

Rice. one

Roof materials must comply with building codes and regulations (SNiP). To increase the service life of the wooden elements of the roof structure, it is recommended to treat them with antiseptics and fire retardants. When doing this, use substances that are not aggressive for roofing films and coatings. The minimum slope angle at which Luxard composite tiles can be used is 12 degrees. At angles of inclination of less than 12 degrees, Luxard composite tiles perform only decorative functions. When laying Luxard on wooden roof structures, as well as on other types of structures, the pitch of the rafters depends on permanent and temporary loads, as well as on the individual architectural features of the roof and ranges from 600 to 1500 mm. Direct contact of wooden roof elements with stone structures is unacceptable. Bitumen-based waterproofing is placed between the wood and stone to prevent decay (see Fig. 2).

The lower edge of the base is cut along the frontal board, the upper - along the axis of the ridge, as shown in Fig. 3.

• In this case, the width of the flooring from the edged antiseptic board should be 23 cm from the axis of the groove.
• Before proceeding to the next stage of installation, it is necessary to carefully measure the truss structure.
• Check for deviations in the corners of the rafters.
• Correct, if necessary, deviations in the truss system.
• Completion of preparation truss system is the installation of the frontal board along the cornice overhangs.

b) Roof ventilation

To increase the service life of roof structure it is necessary to provide ventilation for each element of the roofing system.

Rice. 6a	Rice. 6b

ATTENTION!!! The under-roof ventilation system must exclude areas with stagnant air, the so-called "air bags". Therefore, it is necessary to ensure complete washing of the entire under-roof space with outside air.

Cold attic

In this case, two spaces are ventilated (see Fig. 6a):

1. The space between the roofing and the special film to remove moisture.
The ventilation system consists of: an opening for the inflow of outside air (1); channels above the roofing film for its circulation (2), exhaust holes in the upper part of the roof (3).

2. Rafter system
The ventilation system consists of: an inflow hole in the eaves; exhaust holes in the ridge (in this case, it is necessary to provide for a rupture of the roofing film in the ridge).

Attic

In the attic (see Fig. 6b), the truss system is hidden in the insulation circuit, so the entire ventilation load falls on the space between the roofing and the film. The ventilation system consists of three main elements: openings for the inflow of outside air (4), channels above the thermal insulation for its circulation (5) and exhaust openings in the upper part of the roof (6).

Fig 8. The structure of the attic pie.

Calculation of the area of ​​ventilation openings

Exhaust area ventilation holes is 1/300-1/500 of total area roof insulation. At the same time, 35-40% of the area obtained falls on the supply openings (cornice), 60-65% falls on the exhaust openings (horse).

Special films

Depending on the functional use of the attic space, a film is mounted over the rafter legs:

• in the case of a cold attic - a special roofing waterproofing polymer fabric with a density of 70-140 g / m2 (vapor barrier film).
• in the case of a combined coating (attic) - a special diffusion waterproof membrane for hydro and wind insulation with a density of 60-140 g/m2; (breathable film).

Laying the protective film and mounting the lathing under the Luxard panels

a) Film laying

Rice. nine

As shown in fig. 9, a protective material is laid along the axis of the valley and fixed with a construction stapler along the outer edges of the formwork of the valley with a step of 15 cm. On the plane of the slopes, the film is rolled out in horizontal stripes. The primary fixation of the film to the rafters is carried out with a construction stapler. The lower edge of the starting web of the film is at least 2 cm on the frontal board and fixed on it with a construction stapler. Each next row of film finds on the previous one, while an overlap of 15 cm is organized, according to the principle of water cascading.

If the slope plane is limited on the side:

• pediment, then the film should hang 20 cm from the gable truss structure (these 20 cm will be needed later) (see Fig. 10).

When connecting to pipes (or to vertical walls) the roofing film is cut with a margin of 10 cm to overlap the pipe (or wall) and fixed with bitumen tape.

b) Installing the counter batten

Choice of counter battens

The necessary ventilation of the under-roof space in the combined covering (attic) is organized using a counter-lattice - bars stuffed along the rafters with a section of 50x50 mm or 50x75 mm (depending on the slope of the roof). In this case, the final fixation of the film on the rafter structure occurs.

Eaves counter beam

Rice. 12

The lower edges of the counter-lattice on the cornice overhang are the support of the drip. Therefore, it is necessary to organize for each bar of the counter-lattice a cornice overhang relative to the frontal board, as shown in Fig. 12. The value of the overhang is the sum of the thickness of the wooden substrate under the hooks of the gutter system (approx. 2 cm) and 1/3 of the cross section of the gutter (approx. 4 cm). Through the space between the wooden substrates, outside air is taken to ventilate the under-roof space. If the drainage system is not installed, the installation of wooden substrates is not required.

Valley counter grate

Rice. 13

Along the axis of the valley (left and right), we mount two pairs of bars so that a distance of 15 cm is maintained from the axis of the valley to the nearest edge of the inner bars. The inner bars with a section of 40x40 mm are the support for the catchment element of the valley. The cross section of the outer bars is similar to the cross section of the counter-lattice. Their role is to support the edges of the step lathing. A ventilated gap of 50 mm remains between the main counter-lattice and the counter-lattice bars along the valley axis (outer bars along the valley) (see Fig. 13).

The counter-lattice of the valley overlooking the slope

Along the axis of the valley, at a distance of 23 cm (left and right), we mount the bars of the counter-lattice, as shown in fig. fourteen.

A ventilated gap of 50 mm remains between the main counter-lattice and the bars of the roof rib counter-lattice (see Fig. 15).

c) Installation of step battens under Luxard panels

Depending on the pitch of the rafters, a different section of the battens is used. With a rafter pitch of up to 1000 mm, bars are used in the main section with a size of 50-50 mm with a relative humidity of not more than 20%. With a larger rafter pitch, check with your architect (designer) for the size of the cross-section of the lathing bars. In this case, the cross section of the bars must be increased.

Rice. 16

It is recommended to install the crate from the bottom up (Fig. 16). The lower bar of the batten is mechanically fixed with a 30 mm offset from the overhang of the counter batten. Subsequent rows are mounted with a constant step. In this case, the pitch of the crate is determined in place, taking into account the overlaps of the panels, and is approximately equal to 365 mm. This condition is decisive, since the accuracy of measuring instruments from different manufacturers at different air temperatures is not equal to the standard. The last beam of the step batten (in the ridge part) is not brought to the axis of the ridge by 20 mm.

d) Organization of gable overhangs

Rice. 17

After completing the installation of the counter-lattice and the step lathing, a trim is mounted under the Luxard panels along the pediment, as shown in fig. 17. Top part platband is separated from the plane of the lathing under the composite tile by 30-40 mm. At the same time, special films that are mounted under composite tiles are wound on the upper end of the casing.

Installation of Luxard component systems

Before installing Luxard roofing, place wooden underlays under the gutter anchors (hooks). This must be done to ensure the flow of outside air between the gutter of the drainage system and the front board.

a) Eaves

The metal eaves plank is laid with the upper shelf (short side) on the first beam of the step batten, and the second shelf rests on the overhangs of the counter batten (see Fig. 18). The plank is fixed with nails in increments of 25 cm in the upper shelf to the bar of the step crate.

During installation, the prevailing side of the winds (wind rose) is taken into account. The order of fastening sheets is carried out from the opposite side of the prevailing winds.

The laying of the overlying row is carried out with a run-out of seams. Luxard panels are fixed with special galvanized nails painted to match the color of the roof (see Fig. 19):

• One nail in the center of the extreme waves of the top shelf of the panel. In this case, it is necessary to hammer in nails perpendicular to the plane of the slope.
• One nail at least in every second wave of the bottom wall of the panel. In this case, it is necessary to hammer in nails at an angle of 600 to the plane of the slope and in the place where the wave touches the step crate.

c) Gable

The Luxard panels adjacent to the pediment are cut out taking into account the overlap on the casing (2.5 cm). The panel is cut out 2.5 cm more, then 2.5 cm of the panel is clamped in a pre-prepared vise and bent 900 upwards. The fixation of the cutout panels is carried out similarly to the whole panels according to fig. 19. To reduce the deformation of the sheets and maintain the aesthetic appeal of the roof, bending and straightening of the sheets must be performed using a vice with metal corners of the required length pre-welded onto the "cheeks". Panels are bent at a temperature not lower than +5 degrees Celsius.

d) Valley

The catchment elements of the valley are laid along the axis from the bottom up (Fig. 22). The elements of the valley are fixed with special galvanized nails. Nails are driven through the shelves of the valley into the upper plane of its inner bars in increments of 25 cm. The first element of the valley is placed on the lower shelf of the dropper. The part of the valley element that goes beyond the drip is cut off.

Rice. 22

Each overlying element of the valley is pushed into the underlying one with subsequent fixation. All overlaps are organized according to the principle of water cascading and are 15-20 cm. A special foam sealant is glued along the valley (left and right) at a distance of 1-4 cm from the sides of the catchment element.

ATTENTION!!! Before gluing special foam seals, it is necessary to clean the contact surface of the valley element from contamination. For a tighter adjoining of the foam sealant to the Luxard panels, it is necessary to make transverse cuts in it under the walls of the Luxard panels with a depth of 3 cm.

The Luxard composite tile panel is placed on the valley element by 8 cm and bent down so that the distance between the lower bend of the composite tile and the valley element is 1 cm (Fig. 23).

Rice. 23

e) Valley leading to the slope of the roof

The exit of the valley on the panel of composite tiles must be glued with a special waterproofing material. Use a profiled hot-painted aluminum strip as a catchment element (see fig. 24). Bend the long sides of the strip 2.5 cm up (we get the sides of the valley). Fasten the resulting gutter with six clasps to the counter-lattice using galvanized roofing nails 2.8x25 mm (see Fig. 25). To prevent the gutter from slipping, nail its top end with four nails.

ATTENTION!!! It is unacceptable to nail directly the gutter itself along the length.

f) Rib

Rice. 26

On the ribs with a step of 60 cm, install wooden spacers, or special metal fasteners for the spinal bar. Their height is regulated locally. The recommended cross-section of the spine beam with a given spacer spacing is 50x50 mm (see Fig. 26).

Cut the panels adjacent to the rib (see Fig. 27) along the axis of the rib, then clamp 3 cm of the panel from the side of the rib in a pre-prepared vise and bend it 900 upwards. Fixation of cut panels is carried out similarly to whole panels. The rolled aeroelement of the ridge is laid down with self-adhesive strips. After mounting the ridge element is removed protective film and the air element is rolled with a rubber roller to the Luxard panels until it is completely glued to them (see Fig. 28). Semicircular ridge elements on the ribs are mounted from the bottom up and laid with an overlap of 2 cm (Fig. 28). The semi-circular ridge element is fixed from above with special galvanized nails to the back beam.

Close the end of the first semicircular ridge element with a cap cut from a flat sheet. The cut-out plug is attached with special galvanized nails to the end of the spinal bar (Fig. 28).

Rice. 27	Rice. 28

g) Connection to a stone pipe

Option 1

Composite tile panels are closely adjacent to the pipe. The joint of panels and pipes is waterproofed with a special rolled self-adhesive waterproofing material. To prevent slipping of the waterproofing from the pipe, it must be fixed mechanically with special strips (Fig. 29).

Composite tiles adjacent to the side parts of the pipe are bent at the junction of the pipe and the slope, as shown in fig. 31.

The connection to the wall is a special case of the connection to the pipe and is carried out in a similar way.

h) Skate

Rice. 33

On the extreme rafter pairs of legs of one ridge, fastenings of the ridge beam are installed, the height of which is regulated locally (see Fig. 33). Along the cord stretched between the extreme fastenings of the ridge beam, the remaining fastenings of the ridge beam are installed on each pair of rafter legs. The ridge beam with a section of 50x50 mm (or 50x75 mm) is fastened with self-tapping screws to the fastening of the ridge beam. The top row of slope panels is not full-length, so it is necessary to cut the panel along and profile the support step on a vise for laying on the crate. Fixation of cut panels is carried out similarly to whole panels. The air element of the ridge is laid on the ridge beam and fastened to the beam with nails in increments of 25 cm.

The rolled aeroelement of the ridge is laid down with self-adhesive strips, after mounting the ridge, the protective film is peeled off and the aeroelement is rolled with a rubber roller to the Luxard panels until it is completely glued to them. Semicircular ridge elements are laid with an overlap of 2 cm and fixed from above along the edges with galvanized nails to the ridge beam.

The places of intersection of the edges of the slope with the skates are made using a pattern from the ridge element, according to the diagram in Fig. 34.

To organize exits to the roof of ventilation systems and ventilation of the under-roof space, it is recommended to use special roofing accessories that are supplied in the kit. On fig. 35 shows schematically how they are attached.

• Roofing elements (flanges) for pipe passage
• Roof space fans
• Cuffs and seals for sealing passages through the roof of antennas and flagpoles.
• For installation, follow the installation instructions for the duct included in the package.

End of installation

• All cut edges of aluzinc components must be primed.
• The heads of the nails and the places where the sprinkles are lost are first covered with soil, then sprinkled granules are applied to them, and then everything is fixed with varnish.
• The joints of composite elements in complex assemblies must be filled with a mixture of primer and powder, then varnished.

It is recommended to follow these instructions when installing Luxard composite tiles. In case of non-compliance with the above installation rules, the use of non-recommended components, violation of building codes and regulations in the design of roof structures and roofing work, the product warranty does not apply.

Composite tile METROTILE:
Installation instructions for METROTILE composite tiles

Before you get acquainted with the instructions for the installation of composite tiles, we would like to remind you that the guarantee for the material only applies in case of correct installation, according to the written instructions from the manufacturer. The warranty is only valid when using genuine MetroTile® elements.

Roof construction - difficult task, which includes the solution of such aspects as:
a) ensuring the waterproofing qualities of the roof;
b) ensuring proper ventilation of the under-roof space;
c) solving the problem of the aesthetic appearance of the roof;
d) providing roof insulation;
e) solving the problem of water and snow drainage;
e) ... and much more

ATTENTION! Beware of fakes!

Recently, the market has a large number of materials that look similar to MetroTile® products. Pay attention to the markings on the back of the roofing sheets.

For roofing work, specialized construction organizations licensed to perform construction works.
This manual describes the installation of MetroTile ® composite shingles using basalt based insulation as well as under roof waterproofing. This manual is not a manual for the installation of these materials.

To ensure compliance with the durability of the roof and the supporting structure, it is necessary to treat all wooden elements of the roof structure with antiseptic compounds.

If work is carried out on the roof associated with chasing, plastering or painting, then in these places the tiles must be securely covered with a protective film.

Installation of composite tiles is allowed at temperatures from -10 0C to +35 0C, the use of a repair kit is possible at temperatures above +5 0C.

Storage of composite tiles at the construction site

When loading and unloading composite tiles, avoid mechanical damage to the surface of the material.

Sheets and accessories of composite tiles should be stored on pallets in their original packaging or on bars laid in 0.5 m increments on a flat surface in a dry, well-ventilated area.

To protect the tiles from building dust and dirt, it is recommended to cover the material with a dense waterproof cloth. It is necessary to store repair kits in a dry, well-ventilated area with a temperature not lower than +5 0С.

During storage, it is necessary to protect the decorative surface of the composite tile from sparks.

If the surface is dirty, wash off the dirt with a mild detergent. Do not use abrasive or solvent based cleaners. Do not use a crowbar, scraper, snow shovel to clear snow and ice.

Composite tile materials and accessories

MetroTile® materials and accessories allow roofing of any complexity. A complete list of parts required for the installation of a composite roof is presented in product catalog.

All accessories are universal for any collection of composite tiles

Tools and fixtures for the installation of composite tiles

When installing MetroTile ® composite tiles, the following construction tools are used:
Hand tool:

Preparation of the truss structure, counter-lattice

Installation of the truss structure is carried out in accordance with project documentation, while snow and wind loads in a particular area should be taken into account.

The minimum slope of the slope at which the use of composite tiles is possible is 1:5 (approximately 12 degrees). If individual elements of your roof have a smaller slope, then you must first perform 100% waterproofing of these elements (for example, with rolled bituminous materials on a continuous wooden deck), and install composite tiles for decorative purposes.

The ends of the rafters are sawn vertically. On the rafters Fig. 4.1 - 1 anti-condensate waterproofing is laid. It is recommended to use: Yutacon-140, Nicofol NW, DELTA MAXX or their analogues. If the thickness of the insulation is equal to the thickness of the rafters, it is necessary to use Tyvek superdiffusion waterproofing.

Waterproofing is mounted with horizontal sheets, from the bottom up, starting from the eaves, with vertical overlaps of at least 150 mm and horizontal overlaps of at least 100 mm. At the same time, it is necessary to ensure that the film sags between the rafters by 1-2 cm. The first sheet of waterproofing hangs below the edge of the rafters by 100 mm. In the upper part of the slope, the waterproofing is not extended to the ridge by 100 mm to ventilate the VK-2 space Fig. 4.1 - 2.

On the rafters, over the waterproofing, a counter-lattice is stuffed, a bar with a section of 50x50 mm, to create a ventilation duct VK-1, fasten the waterproofing and ensure ventilation of the under-roof space Fig. 4.1 - 2 - A. The lower end of the bar of the counter-lattice is sawn vertically and hangs over the edge of the rafter by 40mm. Rice. 4.1 - 1

If the roof slope angle is less than 200, the counter-lattice is made of bars with a section of 50x75 mm to increase the cross section of the ventilation duct VK-1 Fig. 4.1 - 2 - B.

If the roof structure has a valley, then the installation of waterproofing and counter battens should begin with the valley (in accordance with P 4.8). During the installation of thermal insulation, make sure that there is a ventilation duct VK-2 between the waterproofing and thermal insulation.

ATTENTION! The presence of ventilation ducts VK-1, VK-2 is a prerequisite for the normal operation of the roof! As a result, the functioning of the roof is ensured without freezing of ice and the formation of condensate.

If superdiffusion waterproofing is used, there is no ventilation duct VK-2.

Lathing installation

For framing apply wooden bars with a section of 50x50 mm, if the pitch of the rafters is W Fig. 4.1 - 2. does not exceed 1000 mm. With a larger pitch of rafters, the cross section of the bars must be increased in accordance with the recommendations of your designer. The moisture content of the material must not exceed 20% of the dry weight.

The installation of the crate is carried out from the bottom up,. The lower batten is nailed at a distance of 20 mm from the lower end of the counter batten bar Fig. 4.2 - 1 and serves to fix the bottom row of sheets Fig. 4.2 - 1 Callout I. Join the battens of the battens on the battens of the counter batten. The length of the lathing bars must be at least two spans between the rafters.

It is important that the distance between the lower edges of the purlins must be kept equal to 370 mm! This condition, necessary for the formation of a lock between joined sheets of composite tiles, provides reliable waterproofing, wind protection and aesthetic appearance roofs. For this purpose, you need to use templates that can be made from improvised means. 4.2 - 1.

The upper row of the crate forms an unregulated distance A to the ridge. The optimal length of the rafter is its length at which A = 370 mm, which corresponds to a whole sheet. The ridge battens of the battens required for fastening semicircular ridge elements must be fastened on both sides of the ridge at a distance of 130 mm. Rice. 4.2 - 1 Callout II.

The ridge battens of the battens necessary for attaching the ridge ridges must first be trimmed and fixed on both sides of the ridge at a distance of 120 mm.

Rice. 4.2 - 1 Callout III.

If your roof contains valleys, then the lathing bars should be 180 mm to the right and left of the valley line. Installation in a valley is described in detail in Section 4.8.

Installation of composite tiles on the eaves

1. - Install the cornice board. The thickness of the cornice board is chosen equal to 40 mm.
2. – Fasten the eaves board securely to the rafters with nails.
3. – Install the gutter fixing brackets on the eaves board. Fig. 4.3 - 1

Callout II. If you do not plan to install gutters, then install a dripper for condensate on the eaves board Fig. 4.3 - 1 Callout I. Condensate drip can be made from a cornice strip. 4.3 - 2. The consumption of the eaves strip will double in this case.

1. – Install the cornice element, starting from the edge of the cornice.
2. – The cornice element is fastened with 4 nails.
3. – Install the remaining eaves elements with an overlap of at least 100 mm.

ATTENTION! When installing the cornice, make sure that:
– a waterproofing film is laid on top of the cornice board, so that there is an unhindered flow of condensate into the gutter of the gutter system. 4.3 - 1 Callout II or on the condensate dripper Fig. 4.3 - 1 Callout I;
– the dropper of the cornice strip goes into the drainage system;
- between the eaves element and the waterproofing, space is left for air to flow into the under-roof ventilation through the ventilation duct VK-1 (dotted line);
- there are channels in the cornice filing for air inflow into the under-roof ventilation through the ventilation duct VK-2 (dotted line).

Installation of composite tiles on the roof slope

Start laying sheets with an overlap in the direction from top to bottom (the lower element goes under the upper one). When laying, the sheets from the top row, already fixed at the top, are lifted, and the next sheet is placed under them. Then the top of the new row of sheets, together with the bottom of the previous row, is nailed to the crate.

ATTENTION! When choosing the order of laying sheets in each row, one should take into account the prevailing directions of wind flows in a given area. 4.4 - 1 - A or Fig. 4.4 - 1– B.

Sheets must be installed in a checkerboard pattern with a lateral offset S between rows. In places of overlap, more than three sheets should not converge.

Side offset between rows S and side overlap between sheets B see fig. 4.4 - 1 should be selected depending on the collection of composite tiles according to the table:

On Fig. 4.4 - 2 shows at which points and in what sequence nails should be hammered, depending on the collection of composite tiles. The diagrams are given for the case when the next sheet in a row is superimposed on the left of the previous one. If the sheet is the last in the row, then a 4a nail is used to secure its free edge. Nails should be hammered at an angle of 450 to the surface of the material Fig. 4.4 - 2 Callout I.

If necessary, nail heads are painted with paint and covered with stone powder. Paint and powder are supplied as a repair kit. Nails can be hammered in by hand Fig. 4.4 - 3 - A or with a pneumatic gun Fig. 4.4 - 3 - B. In the case of using an air gun, installation can be carried out from the bottom up, being below the sheet to be mounted.

Attach a wind board with a section of 25x130 mm to the ends of the bars of the crate.

ATTENTION! The upper edge of the wind board is set so that the end plate barely touches the surface of the roofing sheets with curly teeth. Stick a universal sealant on the roofing sheets. Rice. 4.5 - 3

End plates are mounted from the bottom up. The lower end of the first end plank from the eaves is closed with a cap of the end plank. The plug is inserted inside the end plate, sealed with silicone and fastened with 4 self-tapping screws. Before fixing, all end strips should be laid out on a windboard. Make sure the planks are laid evenly and correctly, then nail the planks to the windboard - 5-6 nails per plank Fig. 4.5 - 4.

Instead of an end plate, a semicircular ridge can be used.

Cross-section of the end plate attachment point, see Fig. 4.5 - 5 - A. If the thickness of the roofing cake on the gable exceeds 130 mm, place an additional apron made of a flat sheet under the end plate. Rice. 4.5 - 5 - B

Along the hip ridge, at a distance of 150-160 mm, necessary for fastening a semicircular ridge element or at a distance of 120-130 mm, necessary for fastening a ribbed ridge element, 50x50 mm bars are attached to the crate. Rice. 4.7 - 1.

MetroTile® sheets adjacent to the hip are prepared according to Fig. 4.7-2 and Fig. 4.7- 3. To do this, measure required size sheet and, in accordance with it, a fold line is marked on the sheet. An allowance of 50 mm is given to it and a cut line is applied. The workpiece is cut off along the cutting line Fig. 4.7 - 2.

Along the fold line, the edge is bent upwards by 900 using a manual or special tool Fig. 4.7 - 3. Measurements are made on the roof, but sheets are cut and bent usually on the ground.

Lay semicircular ridge elements as shown in Fig. 4.7 - 4.

Installation of composite tiles in the valley

To the right and left of the valley line, boards 25 mm thick under the valley are fastened to a width of at least 200 mm. 4.8 - 1.

The waterproofing installed along the slopes is laid on top of the waterproofing laid along the valley with an overlap of at least 150 mm.

The elements of the valley are nailed to the valley boards from the bottom up, starting from the eaves with an overlap of 100 mm. Nails are hammered at the maximum possible distance from the valley line and at a distance of 30 mm from its upper edge. Each subsequent element is pushed into the previous one and also fastened with nails. It is recommended to install a universal seal along the edge of the valley.

ATTENTION! The valley element is supplied without stone dressing.

Sealing the heating (ventilation) pipe

Before installing roofing materials, it is necessary to plaster heating and ventilation pipes. Pipes should not have laps, ledges, etc. In Fig. 4.9 - 1 shows a section of a heating (ventilation) pipe in plane A, parallel to the rafters.

Installation of end and side connection to the wall

It is carried out in accordance with Fig. 4.9 - 2.
Installation of tiles on the external and internal fracture of the slope

Installation of tiles on the external slope fracture is shown in Fig. 4.11 - 1.

Installation of tiles on the internal fracture of the slope is shown in Fig. 4.11 - 2.

• The size depends on the slope angle of the slopes and is specified during the installation of the crate.
  Installation of complex roof fragments

Semi-circular or tapered roofing elements are installed using a flat sheet of MetroTile®. In this case, a solid crate made of materials such as moisture-resistant plywood, OSB or edged board is mounted as a base.

For mounting, a flat sheet is cut into fragments from which mounting is made.

Application of transparent metrotile® sheets and roof window installation

For illumination of cold attics, construction of bright outdoor terraces and sheds, you can use transparent sheets. The transparent sheet is made of PVC and has the same shape and size as regular MetroTile® sheet, so no additional accessories are required. If it is necessary to provide light through the insulated roof, then roof windows are used.

Skylights are purchased complete with flashings for high-profile roofing materials. The accessories needed to seal the roof window are included in the window kit.

When preparing the base for the installation of the Metrobond roof, it is necessary to take into account the size of the roof window, the distance between the rafters and the batten to be mounted.

ATTENTION! It is necessary that the level of the roof window flashing be 25 mm lower than the crate.

To do this, in the bars of the crate adjacent to the window frame, a quarter is selected for the salary rail and to a depth of 25 mm. The batten is reinforced from below in accordance with the recommendations of the roof window supplier.

Installation of snow retainers

The structure of the MetroTile® material prevents the avalanche-like descent of snow from the roof.

Installation of composite tiles over the old roof

MetroTile® Composite Shingles install quickly and efficiently over old or obsolete roofing, allowing the home owner to remodel the roof. Mounting technology allows you to mount MetroTile® composite tiles on seam roofs, roofs with a corrugated profile and flexible tiles.

The counter-lattice on the folded roof is mounted from a bar with a section of 50 mm x 50 mm with a step of 500 mm Fig. 4.15 - 1. Next, install the battens and the MetroTile® tiles themselves in accordance with these instructions.

If the roof is, for example, folded, Fig. 4.15 - 2 leaks, then it is necessary to additionally add a layer of under-roof waterproofing.

For mounting over a roof with a wavy profile, with a step of no more than 500 mm, a counter-batten is mounted Fig. 4.15 - 3. For this purpose, along the wave of the old roof, it is necessary to fix a bar, the cross section of which, in height, must be greater than the height of the wave, and the bar must be hewn in width so that it fits snugly into the recess of the wave. Next, the batten and the MetroTile® tile itself are installed in accordance with these instructions.

Control grating according to shingles mounted from a bar with a section of 50 mm x 50 mm with a step of 500 mm.

Ventilation of the under-roof space

The total area of ​​the dormer windows is assumed to be at least 1/300 of the area of ​​the horizontal projection of the roof. If cold attic missing or not provided for by the project dormer windows, it is necessary to install roof fans Fig. 5 - 2.

Roof fans are necessary to ensure the exit of air from the ventilation ducts in the ridge area.

Support platforms for roof fans MetroTile® repeat the profile of the chosen material - Metrobond (MetroBond®), Metroroman (MetroRoman®), Metroshake (MetroShake®). The fans are made of PVC and are protected from above by the same basalt dressing as the rest of the parts.

To achieve the recommended performance of the ridge ventilation outlet, roof fans should be installed no further than 0.8 m from the ridge, one for every 50-70 sq. m of roof surface. In addition to providing effective ventilation, roof fans prevent access to vulnerable attic space rainwater, snow and birds.

Care and maintenance of composite tiles

Tiles must not come into contact with copper or copper-plated materials.

If at installation work the surface of the sheet is dirty, then the dirt can be washed off with a mild soapy solution. The use of aggressive cleaning agents is prohibited.

This type of tile is considered the material of a new innovative generation. It combines excellent design, good quality, reliability in use. The basis of a composite tile is a sheet of steel, but it is absolutely not similar to a metal tile.

This type of roofing material is considered the material of a new innovative generation. It combines excellent design, good quality, reliability in use. The basis of a composite tile is a sheet of steel.

A characteristic feature of a composite tile is a high-quality steel sheet embedded in its base with a layer of aluzinc applied to it, processed on top with natural stone chips. This significantly increases the anti-corrosion properties of the metal, so the guarantee for such roofing material is more than 30 years.

Roof structure:

The outer surface of the processed sheet metal sprinkled with colored stone chips. A layer of acrylic glaze is applied on top of the stone granulate, it firmly holds the granulate on the surface of the sheet and reliably protects the top layer from dust and pollution.

The color scheme of such a material pleases with diversity, since mixing allows you to get unique and diverse iridescent color shades. Composite tile roofing huge selection colors.

Which HRC is better

• In this form, both the seductiveness of the design and the quality of the material are taken into account. In addition, the range includes medium-profile sheets, similar to standard metal tiles, and high-profile steel sheets, reproducing Romanesque ceramics. The look of a slate or chip roof helps to recreate the low-profile sheets made to look like shingles.
• High durability due to high quality anti-corrosion treatment. In fact, it is not corrosive, and the additional acrylic layer firmly holds multi-colored granules on the sheet surface, which additionally protects the roof from damage. Due to the high-quality special fastening, this tile has no windage, which helps the roofing material to easily survive any bad weather.
• For any roof, the issue of weight is very important, since a large weight requires additional strengthening of the roof, which, of course, is very expensive, therefore, having a light weight, it is best suited for any type of building.
• It is suitable for a variety of buildings with an angle of inclination from 120 to 900, since during the assembly process it can be bent, cut and reshaped as desired.
• Thanks to the acrylic layer and granulate, the sound of rain and hail is successfully dampened, which makes the stay in the building pleasant and comfortable.

Coatings made of this material have excellent performance and, despite their similarity with metal tiles, differ from it in many respects. These differences are especially noticeable when considering the order of installation of composite tiles, as well as when choosing the tool necessary for the work.

Features of installation of tiles made of composites

A distinctive feature of the arrangement of any roof structure is the need to prepare a reliable support frame (battens). Such a base is mounted on top of a multilayer structure called a roofing pie and consisting of the following mandatory components:

When constructing roofs with a small slope, it often becomes necessary to equip another supporting frame (counter-lattice) used for mounting the waterproofing layer. In addition, the foundation design should provide for the possibility of attaching such mandatory elements of a tiled roof as ridges, valleys, cornices and special end strips.

When constructing roofs from composite tiles, one should also not forget about the chimney pipes that come to the surface and are available on.

Necessary tools and accessories

Before starting roofing work, it is necessary to prepare tools and additional elements coatings that ensure its functionality and give the structure a completely finished look.

To perform basic work operations, you will need the following standard tool kit:

• two hacksaws (one for working with metal, and the second for wood);
• an ordinary hammer, metal scissors and a tape measure;
• mounting gun, for which you can choose a product from such well-known manufacturers like "Hilti" (Liechtenstein) or "Toua" (Poland);
• a typical screwdriver that can be replaced with an electric drill of any company (“Bosch” or “De Walt”, for example);
• a circular saw from Bosch, Hitachi or Makita with a set of discs;
• devices for bending workpieces and their riveting.

In addition, before installation, you will need such mandatory elements of any tile covering as ridge corners, valleys, cornice and end strips, etc.

Roof base preparation

The installation of the waterproofing layer is carried out horizontally relative to the eaves. The overlap between the waterproofing sheets must be at least 15 centimeters. Lathing is carried out with a beam with a section of fifty to fifty, with a lathing step of 370 millimeters. For mounting accuracy, it is advisable to be guided by the template, since if the crate step is incorrect, problems will arise when joining the sheets in the future.

For coatings made of composite materials a very important indicator is the minimum slope of the roof, which should not be less than twelve degrees.

Important! At smaller slope angles, the base will need to be finalized, as well as additional waterproofing along the solid flooring.

Otherwise, the coating will not fulfill the functions assigned to it and can only be used as a decorative decoration.

When choosing a scheme for a frame base (lathing), the distance between the support bars is selected taking into account the following factors:

The main requirement for the supporting structure is the ability to withstand the total load, taking into account all the factors listed above.

The photo shows a drawing of a typical crate base for tiles, which shows its main dimensions.

It follows from the scheme of the crate that the step with which it is stuffed horizontal bars, is set according to a template made taking into account specific operating conditions. At the same time, the step of stuffing vertical bars varies in the range from 60 to 150 cm.

In addition, at the location of the valley, additional support bars are necessarily provided, spaced at a distance of about 15 cm from its axis. For their arrangement, you can use an edged board with a thickness of about 2.5 cm, which is pre-treated with a protective compound (antiseptic). The entire resulting structure is rigidly connected to the rafters that take the load from it.

The upper and lower boundaries of such a base are the ridge line and the frontal cornice board, respectively.

Installing the cornice and ridge

The arrangement of the cornice part of the tiled slope is carried out according to the following standard scheme:

• first, a cornice board about 4 centimeters thick is attached to the rafters;
• after that, brackets are installed on top of it, designed to fix the gutters;
• then, limiting strips are fixed along the edges of the eaves, after which the tile blanks themselves are mounted, laid with a slight overlap (approximately 10 cm).

Please note: In the event that the gutters are not provided for by the project, a dripper is installed along the cornice board, designed to remove moisture and condensate.

When installing the cornice strip, the following important points must be considered:

• this element is installed with a slight slope towards the drain and must be treated with a liquid waterproofing material;
• the dropper placed on the eaves must have a direct “exit” to the drain;
• a small ventilation gap should be left between the elements of the eaves and the layer of protective waterproofing.

From the above description, it follows that the installation of the cornice part is in many ways similar to similar procedures for other types of roofing material.

To fix the ridge elements of the general tile covering, special nails must be used, nailed to the upper bar of the crate. When arranging shed roofs, a steel sheet of the required size is usually used as a ridge, carefully folded along the ridge contour and fastened to the base with pre-prepared hardware (nails).

For the manufacture of this element on roofs with two slopes, special-shaped blanks are used, designed specifically for this purpose.

Final roofing installation

Immediately before the installation of roof tiles made of composite materials, heating and ventilation should be taken care of (usually they are pre-plastered). For reliable isolation of the junctions of these elements with the main tiling, standard-shaped blanks, called aprons, are used. These elements are attached to the crate in the joint area by means of a set of self-tapping screws with dowels.

The final laying of roofing blanks is carried out "from top to bottom" with the arrangement of tile sheets in a checkerboard pattern. In accordance with the generally accepted installation scheme, each subsequent sheet is inserted under the previous one with a slight lateral displacement and overlap, the magnitude of which depends on the brand of the composite material used.

The next element of the roofing, together with the lower section of the previous row, is fixed on the crate by means of one hardware.

Important! At one overlap point of adjacent roofing blanks, no more than 3 sheets of tile material should converge.

Walking on the surface is necessary only in elastic shoes, stepping exclusively on the low part of the wave.

There are various types of roofing: ondulin, corrugated board, slate and others. Not so long ago, another one appeared - composite tiles.

It is based on a metal profile, aluzinc and a polymer layer are applied to the material, and not galvanized. Outer side covered with mineral granulate (other types do not contain this layer).

Composite tiles combine the best qualities of other types of roofs and are practically devoid of drawbacks.

The material does not require special storage and transportation conditions. However, mechanical impacts that can lead to damage to the coating, including from fire or sparks, should be avoided (preservation of the external decorative look). It is advisable to store products in a place protected from moisture ingress with good ventilation.

Storage sheets should be laid in layers: between the rows of roofing material, place gaskets made of fabric or wood.

To protect the surface of the product from construction dirt, dust, it is carefully covered with a dense cloth or film. A sponge with a mild detergent composition will help remove dirt. Use of active chemicals and solvents is not recommended. Crowbars, scrapers and snow shovels should not be used to remove accumulated ice and snow in order to avoid damage to the outer edge of the sheets.

Mandatory tools for work

To assemble the structure, you will need construction equipment: manual and special. It is recommended to prepare it in advance.

Manual includes:

• hacksaws for wood, metal;
• metalwork hammer;
• metric tape measure;
• metal scissors;
• mounting gun;
• screwdriver (electric drill, hand drill);
• circular saw with a disc for soft metal;
• bending device;
• riveter.

Special tools include:

• large and small bending machines;
• templates 370 mm;
• guillotine (manual, electric);
• air gun under the dowels.

The use of special tools and equipment is not necessary, but with their help the assembly is faster.

Work on the arrangement of the roof can be performed by qualified craftsmen or the consumer himself. To carry out the installation of composite tiles with your own hands, you need to know the production technology, the construction of the roofing pie and have drawings.

Foundation preparation

In order for the material to qualitatively and reliably perform the declared functions, it is recommended to carefully prepare the truss system, correctly lay out the tool and all the details of the structure. The service life of the roof and the carrier system will correspond to the declared one, if all wooden parts are initially treated with antiseptic substances. The assembly of any roof begins with the preparation of the base.

Installation of composite tiles should be carried out in accordance with the prepared project, drawings and SNiPs. The calculation takes into account all the features of local climatic conditions(precipitation, wind, snow, temperature in the cold and hot seasons).

The minimum ramp slope is 12 degrees. If this value is less, then it is necessary to provide waterproofing to prevent the penetration of moisture between the joints.

Initially, the ends of the rafters are sawn vertically. Waterproofing is attached directly to them, which is laid in horizontal sheets from the lower to the upper edge of the eaves. They overlap: vertically from 150 mm, horizontally from 100 mm. Between the supports, the film should sag a little (within 1-2 cm). The connection of parts is recommended to be done on the rafters. The initial piece should be lowered 10 cm from the edge. The film is not brought to the top of the slope by 10 cm, the fulfillment of this condition ensures the ventilation of the space.

Upon completion of the location of the waterproofing on the rafters, it is necessary to proceed with the installation of a counter-lattice - bars with dimensions of 50x50 mm in section, which serve to provide sufficient space for ventilation under the roof, fixing the film. The lower end must be sawn vertically and hung 4 cm over the edge of the rafters.

Important! Ventilation ducts are necessary for the normal functioning of the roof.

If the building system includes a valley, then the installation of the valley links is carried out first, and the waterproofing of the counter-lattice is laid after.

The crate for composite tiles is made using wooden bars 50x50 mm in section, if there is no more than one meter between the supports (in case of a larger distance, the section is made larger). It is placed from bottom to top. The lower bar is fixed at a distance of 20 mm from the extreme link of the counter-lattice and performs the function of fixing the first row. It is better to connect them on the links of the counter-lattice, and the length of each of them should exceed the length equal to the distance of 2 spans between the supports.

It is required to maintain a distance of 370 mm between the lower edges of the parts. This is necessary to create a lock between adjacent sheets of coating, to provide high-quality protection against moisture ingress, protection from gusts of wind and for aesthetics.

Council. To meet the conditions, make suitable templates from any materials.

The distance from the top row of the crate to the crest is not regulated. It is desirable to select the length of the rafter equal to the length of a single piece of material. Sheathing bars intended for laying the ridge are installed on both sides of it at a distance of 13 cm.

In the presence of a valley, the parts of the battens are located on both edges of the valley line at an indent of 180 mm.

Laying technology

Laying of composite tiles is carried out in a certain sequence:

1. Cornice. The process begins with the installation of a 40 mm thick cornice board, it must be protected with a waterproofing film. The board is fastened with nails to the rafters. Brackets for gutters are mounted on it. On the side of the cornice, the cornice element is fixed with the help of 4 self-tapping screws, nails. The remaining parts are assembled with an overlap (100 mm). Upon completion of the process proceed to the next step.

2. stingrays. On the slopes, the sheets are laid with an overlap of the upper row on the lower one. It is more convenient to work from top to bottom, lifting one layer to lay the bottom one. Fastening is best done at the junction of two parts at once. When fixing, the force, speed, and direction of the wind must be taken into account - for the reliability of the system. The assembly is carried out in a checkerboard pattern with a slight offset relative to each other, observing the following criterion: no more than three parts in the overlap area.

3. Mounting the skate. This is the final stage. Installing a ridge on a metal tile and on a composite tile is approximately the same. Rib combs are fastened with an overlap of 100 mm, and semicircular - 45 mm. The installed parts are nailed (self-tapping screws) to the upper bars of the crate. To prevent moisture (rain, snow) from getting between the ridge components, it is advisable to lay any sealant. You can put end caps on the ends. This method is suitable for work on pitched roofs.

Care of composite tiles

One of the most valuable advantages of composite shingles is that during its operation it is possible not to take special care of it, if all the requirements were met during installation. All that is required later is to periodically inspect the roof, check the tightness of the joints and junctions, sweep away debris and branches.

Of the potential damage, the worn topping is most often detected. Restoring it is very easy. For these purposes, a special repair kit has been developed, which includes a primer and mineral chips. It is enough just to paint the protruding nail heads, seams or scratches with a primer and sprinkle them with a protective material again. Acrylic composition apply at an outside temperature of +5 C. In colder weather, it is necessary to use frost-resistant sealants.

Salt spots can sometimes appear on the tiled surface. They are removed with ordinary soapy water. Chemically aggressive detergents are strictly not allowed for use.

When carrying out inspection and repair, you should walk on it in shoes with soft soles. The roof will be completely safe if you step only on the bars of the crate, and not on the ridge elements.

Used roofing materials must strictly comply with the requirements normative documentation(GOST, TU, technical regulations).

To ensure an adequate level of security and maximum long term services of wooden structures, they should be processed special formulations that prevent fire, mold, rot, insect damage. Do not use chemicals, contact with which can adversely affect the condition of film and membrane materials, as well as other accessories.

Composite tiles Luxard can be used on roofs with a slope of at least 12 degrees. With a smaller angle of inclination roofing will not effectively perform its basic protective functions and can only be considered as decorative finishes roofs. Optimal distance between truss structures depends on a number of factors: wind and snow loads specific to the region, roof configuration, as well as other engineering and architectural solutions. Usually the pitch of the crate is from 60 to 150 cm.

Direct contact of stone and wooden structures can lead to dampness, rotting and subsequent destruction of the elements of the truss system. Therefore, it should be avoided by using special ones (for example, bituminous), as shown in fig. 2.

On the sections of the valleys, it is imperative to lay additional supporting elements. The width should be approximately 15 cm from the central axis of the valley (in both directions - Fig. 3). Recommended material - edged boards 2.5 cm thick, treated with an antiseptic. The structure must rest on the rafter legs.

The upper and lower boundaries of the base for laying composite tiles are the center line of the ridge and the frontal board, respectively.

Before proceeding to the second stage of installation of Luxard composite tiles, it is necessary to carry out accurate measurements all truss elements. If deviations occur in the planned linear and angular dimensions of the structure during the arrangement of the base, they must be eliminated immediately.

2) Ensuring ventilation

Efficient operation of the under-roof space involves ensuring optimal air circulation in all its sections.

The presence of "air bags" - areas in which air stagnates - is NOT ALLOWED. Air exchange with the environment must be constant and intensive.

Cold attic

If the project of the house involves non-residential attic, the single scheme will include not only the crate, but also the entire under-roof space, limited by the roof slopes (Fig. 4a).

The scheme can be divided into 2 segments:

1. The space between the tiles and the film, designed to remove moisture.

Ventilation is carried out due to supply openings through which air enters from the street (1); air ducts above the film coating (2); holes located in the ridge area and intended for exhaust (3).

2. Construction of rafters and battens.

Ventilation is carried out at the expense of the lower supply holes and the hood on the ridge line (special holes are also made in the film material).

PLEASE NOTE: The film should sag slightly (about 2-3 cm - fig. 5). This should not be hindered by the elements of the truss system.

Warm attic

IN attic room(Fig. 4b) truss structures must be protected with insulation. The air circulation system here is limited to the area between the composite tiles and the film.

To avoid wetting the elements of the counter-lattice (due to water vapor formed in the under-roof space), it is necessary to fix a beam about 2.5 cm high along the lines of the rafter legs.

Air circulation here occurs due to the lower supply openings through which air enters from the outside (4), channels located above the layer (5) and the hood in the ridge area (6).

Determining the dimensions of the ventilation openings

The total area of ​​the ventilation openings should be 0.2-0.3% of the area of ​​the insulated roof surface. About 1/3 usually falls on the supply holes located on the lines of the cornices, 2/3 - on the hood in the ridge area.

Films and membranes

The choice of insulating materials laid above the rafters, first of all, depends on how the under-roof space is planned to be used.

For a cold attic, Westmet specialists recommend using TECHNONICOL reinforced moisture and windproof film.

For a warm attic the best option there will be a reinforced superdiffusion membrane trademark TECHNONICOL.

Installation of film and lathing under Luxard composite tiles

1) Film mounting

Horizontal strips of the film are placed on the surface of the roof slopes and attached to the elements of the truss system using a construction stapler.

Valley sections require special reinforcement. On the side of each slope, the strips of film should be laid in such a way as to overlap the center line of the valley by 30 cm or more (Fig. 7). A piece of film with a width of at least 120 cm is additionally laid on top (60 cm on each side of the central axis).

The direction of installation of film strips is from bottom to top. The first strip is laid on the lower edge of the slope with an overlap on the frontal board of at least 2 cm. Subsequent rows are stacked on top of each other with an overlap of about 15 cm.

The order of installation of the film on the sides of the roof slopes depends on design features project.

Gable (fig. 8): after the initial laying, the film strips must hang at least 20 cm. After the installation of the gable, they are fixed.

Rib (Fig. 9): The film on adjacent slopes is fixed along the rib line with a stapler. Westmet engineers recommend placing staples in 15 cm increments. A narrow strip of film is additionally attached over the rib with adhesive tape placed along the entire length of the segment (recommended film width is 30 cm).

In the adjoining areas (to walls, chimneys, etc.), the film material is fixed on the corresponding planes with a 10-cm overlap using a polymer adhesive tape.

2) Arrangement of the counter-lattice

The standard counter-lattice is a system of 5x5 cm bars, which are attached parallel to the rafters on top of the protective film. It provides additional air circulation and securely fixes the film.

Eaves projection of the counter-lattice

For reliable fixation in the lower part of the slope, it is necessary to fix a support beam with a section of 2.5x5 cm. The size of the cornice overhang is equal to the sum of the thickness of the substrate for the drain fasteners (usually about 2 cm) and one third of the cross section of the drain gutter (about 4 cm). The space between the substrates improves ventilation. If the building design does not provide for the installation of a drainage system, substrates are not used.

Control grating in the valley sections

Along the valley, 5x2.5 cm bars are attached (on top of the previously attached 5x5 cm bars). In order not to be mistaken with their location, it is recommended that before that, try on the valley tray directly in the area of ​​\u200b\u200bits future attachment.

Valley counter-lattice on slopes of complex configuration

On both sides of the valley line (15 cm), the elements of the counter-lattice are fixed.

Counter grating in the areas of the roof ribs

On each slope, one bar of the counter-lattice is attached along the central axis of the rib (2 cm from it). Between the main and rib elements of the crate, it is recommended to make a ventilation gap of 5 cm.

3) Lathing for Luxard composite tiles

The optimal dimensions of the bars used to create the crate depend on the step roof structures. If the rafter pitch is less than 1 m, standard bars with a section of 5x5 cm are used. With an increased rafter pitch, larger bars should be used. These issues require detailed study with the designers of the building.

The crate is mounted, starting from the lower edge of the slope (Fig. 14). The lower beam is attached 5 cm from the line of the cornice overhang. The next rows are fixed at an equal distance from each other. The pitch of the crate depends on the type of tile panels (recommended by Westmet engineers, the distance for Luxard Classic tiles is 36.7 cm, for Roman panels - 37 cm). Depending on the specific installation conditions and the roof project, minor adjustments may be made to the specified values.

The upper beam is attached at a distance of 2 cm from the ridge line.

4) Gable overhangs

Having completed the arrangement of the battens and counter battens, it is necessary to install the casing (Fig. 15). The top line of the platband should be located 3-4 cm from the plane of the crate intended for laying tiles. The protective film is laid in such a way as to cover the upper end of the installed casing. After that, a special cornice tape is attached to the lower element of the crate and the frontal board, which provides ventilation for the structure.

Installation of Luxard composite tile components

In order to ensure sufficient air flow into the under-roof space, before starting the installation of Luxard composite tiles, it is necessary to fix special substrates in the lower part, on which the elements of the drainage system will be attached.

1) Cornice

The cornice metal strip is installed on the support board of the overhang of the crate (long side) and fixed on the lower beam of the crate (short side) with nails or self-tapping screws in increments of 25 cm.

Planks are fastened uniformly, overlapping (10-15 cm). At the end section of the valley, a cutout is made in the dropper so that the catchment structure of the valley can fit in it without interference.

If Luxard Roman composite tiles are used, then a foam sealant is attached to the upper shelf of the cornice strip (Fig. 20b).

2) Installation of Luxard tiles

Installation of composite tiles Luxard is carried out from the bottom up.

Roman panels are fastened strictly from left to right, the rest of the panels - depending on the direction of the prevailing winds (starting from the side opposite to this direction). Panels of colors "Garnet", "Malachite", "Onyx" have 3 different types of texture, which are stacked in random order. This provides the best aesthetic effect (imitates the natural fading of the coating).

Installation of rows should be carried out with a separation of seams. The tiles are fastened in accordance with fig. 17 a and 17 b using galvanized nails or self-tapping screws, except for Luxard Roman composite tiles, which are fixed only with special self-tapping screws.

Self-tapping screws and nails are screwed (driven in) along the lines of contact of the wave with the crate at an angle of 60 ° to the plane of the slope. If it is not possible to use fasteners that match the color of the tiles, it is advisable to cover the visible parts of the nails with paint and a special powder.

The tile adjacent to the pediment must be cut off (providing for an overlap on the casing 2.5 cm long). After that, a 2.5 cm strip of the panel is bent upwards perpendicular to the main part (in a vice or on special equipment). It is important to preserve the integrity of the panels and their attractiveness, so the work must be carried out as carefully as possible, at a temperature not lower than 5 ° C.

The end strips are attached to the casing from the bottom up with galvanized nails or self-tapping screws on both sides (pediment and slope, as shown in Fig. 19 a and 19 b). For the greatest strength, it is recommended to fix the planks with an overlap (about 15 cm). As an end plank, a semicircular ridge plank can be used.

The slats are fastened with metal clamps along the central axis from the bottom up with an overlap (up to 20 cm). The recommended distance between clamps is 25-30 cm. On the sides of the sides of the valley (1-4 cm), a foam seal is attached. The surface must first be cleaned of dirt. Optimum adjoining of a sealant to a tile is reached due to cross cuts (depth of 3 cm) under walls of panels.

The edge of the tile panel is laid on the edge of the valley with a margin of 8 cm, which is bent down so that the distance between it and the edge is 1 cm (Fig. 21a, 21b).

5) Valley adjacent to an additional roof slope

Abutment tape must be applied to the zone of contact between the valley and the tile panels. For drainage, it is recommended to use a profiled aluminum strip (Fig. 22a, 22b). The sides are formed by bending the edges of the plank 2.5 cm up. The manufactured gutter is fixed on the counter-lattice with the help of clamps and nails made of stainless material (Fig. 23).

In order to avoid displacement of the drain, its upper end part must be nailed.

It is NOT ALLOWED to fix the gutter with nails along the entire length.

The connection line of two valleys is glued with a sealing tape that matches the color. Gluing the seals and bending the panels is carried out in the previously described order (Fig. 23).

6) Rib

Wooden spacers are fastened along the rib (step - 60 cm) using self-tapping screws or special fasteners designed for the spinal beam (section 5x5 cm). The optimal height is determined directly on the spot.

The tile adjacent to the rib is cut along the line of the central axis of the rib, after which the 3-cm fragment is bent upward perpendicular to the slope plane in a vise or on special equipment (Fig. 25a, 25b).

Cut panels are attached in the same way as standard ones.

The ridge air element is fixed with a self-adhesive layer down. The details of the ridge are laid from the bottom up with an overlap (2 cm) and are attached to the spinal bar with nails or self-tapping screws. After mounting the ridge, the protective film is removed, and the air element is tightly glued to the tile with a rubber roller (Fig. 26a, 26b). The end of the lower element of the ridge is closed with a flat plug made of sheet material (attached to the end of the backbone bar).

7) Connection to the chimney

Option number 1: suitable for buildings whose design does not involve significant shrinkage (not suitable for most wooden houses).

The tile is directly joined to the pipe. A self-adhesive waterproofing is attached to the junction area, which can be additionally fixed with metal strips (Fig. 27a, 27b).

Option #2: universal, can be used for any buildings.

Tiles adjacent to the chimney at the bottom and at the corners are cut at an angle of 45°. The upper edge is folded back (Fig. 28a, 28b). Along the perimeter of the junction of the pipe and the slope, the panels are bent in accordance with the scheme shown in fig. 29a, 29b.

The junction of the slope plane with back side pipes are made using LUXARD branded flat sheet (125x60 cm). It should rest on a solid flooring of wooden boards 2.5 cm thick. The length of the required sheet fragment should be 20 cm more than the width of the pipe, and its width should be equal to the sum of the step of the crate, the height of the “side” formed on the pipe and the height of the strip bent on the counter-crate . The junction is mounted according to fig. 29a, 29b. A sealant is applied to the section of the upper tile adjacent to the pipe.

Metal strips are mounted along the entire perimeter, fixing the structure (Fig. 30a, 30b).

The adjunction of tiles to the wall is carried out in accordance with the above procedure.

Ridge beam fasteners are mounted on the extreme pairs of rafter legs (Fig. 31a, 31b). The height is determined directly on site, depending on the specific conditions of the roof project. Between installed fasteners the construction lace is pulled, forming a straight line. On other pairs of rafter legs, the remaining fasteners are installed, which are aligned along the indicated line.

Westmet engineers recommend a 5x5 or 5x7.5 cm ridge beam. It is fixed to the fasteners with self-tapping screws. Shingles forming panels top row, are cut in height and a support step is formed on them, which is necessary for high-quality installation. They are attached in the same way as standard full-size panels.

The ridge air element is fixed with a self-adhesive layer down. With the help of a special rubber roller, it is firmly glued to the tiles after the installation of the ridge.

The components of the ridge are overlapped (2 cm) and fixed along the edges to the ridge beam with special nails or self-tapping screws.

On the pitched roof the skate is mounted in accordance with fig. 32. For this, flat sheets are used, which are cut taking into account the angle of inclination of the roof and the dimensions of the truss elements. For maximum decorative effect it is allowed to use a semicircular ridge over a flat one.
