Self-insulation of the house outside - some of the most effective ways. External insulation of the walls of the house Insulate the house with ursoy

Effective heat and sound insulation - the necessary conditions for the normal operation of residential premises and buildings. Of course, for many houses, the existing thermal insulation is sufficient, the role of which is played by brick, corrugated board or reinforced concrete.

However, in the case of a harsh climate, the use of additional insulation materials is required.

To date, there are many options for insulation: mineral wool, polystyrene foam, glass wool, etc. , so everyone can choose the material of interest to him.

Ursa insulation: general information

One of the best heaters is the Ursa product. The heat-insulating material is made from glass staple fiber, which has a minimum heat transfer rate.

The material is widely used in the course of work on the insulation of floors, walls, facades, pipelines and attic floors of houses.

The company for the production of insulation appeared in 2002, in the process of merging the two construction giants Pfleiderer and Poliglas, after the acquisition by Uralita of the division insulating materials Pfleiderer.

The Uralita group is a transnational company headquartered in Spain (Madrid). This is one of the oldest construction companies in Europe (founded in 1907).

Specifications

Ursa insulation - suitable material for use in conditions high humidity and load or even direct contact with the ground.

It is produced in accordance with specifications, which apply to fiberglass insulation, has certificates from the State Construction Committee of the Russian Federation, as well as all the necessary hygienic conclusions.

Main technical parameters:

density - from 11 kg / cu. m.;
combustibility class - non-combustible materials;
permissible temperature - from -60 to +320 ° С;
thermal conductivity coefficient - 0.04 W / (m * K);
steam permeability - 0.61 mg / m * h * Pa.

In addition, the insulation has a number of other equally important characteristics that simplify its installation - light weight, flexibility and elasticity.

Due to its structure, Ursa thermal insulation material does not sag. It is produced in the form of plates that can withstand increased loads and sudden changes in temperature.

Advantages of Ursa insulation

The material has a number of advantages that help to solve construction problems of almost any complexity:

Rigidity and strength - the plates are able to withstand a load of up to 50 tons per square meter;
Ecological cleanliness - natural carbon dioxide is used in production, which, unlike freon, is safe for the ozone sphere of the atmosphere;
Frost resistance and moisture resistance - retains its properties even in conditions of high humidity or when in water. Can be used in structures where there is frequent change temperature regime. It is a durable material capable of withstanding over 500 freeze / heat cycles;
Durability - the service life from the moment of installation is 50 years or more. Combustibility - does not burn. The composition includes flame retardants that trap oxygen in the process of getting direct fire on the heater;
Efficiency and minimum labor costs during installation. Light weight and elasticity reduce installation time. Installation does not require special tools and skills.

The material, as a rule, is used for insulation and soundproofing of internal partitions and interfloor ceilings in public and industrial buildings.

Often insulation is used during installation industrial devices And heat exchange equipment. In addition, it is ideal for insulating pipelines. Recently, the material has been used to insulate transport.

All Ursa products come in two basic forms: mats and slabs. Distinctive feature mats - the possibility of seamless installation over large areas.

Interest in energy saving issues is becoming more and more urgent every year. Energy carriers are becoming more expensive by leaps and bounds, so the choice of heat-insulating modern materials is a responsible matter.

Ursa insulation from the concern of the same name, which is part of the URALITA group of companies, is considered one of the best building materials on the European market.

Its use can significantly reduce heat loss during the heating season and protect the home from excessive heating in hot summers.

The company's specialists have developed a large number of varieties of Ursa insulation, a photo of which can be viewed in the illustrated catalog.

URSA insulation - material advantages

Amazing lightness of the material.
Simple and convenient installation.
Flexibility and elasticity.
Moisture and acid resistant.
High fire-fighting properties.
Environmental safety and cleanliness.
Democratic and affordable price.

How much does Ursa insulation cost

Price for this construction material depends on the type of insulation and its total amount. Naturally, walls or floors need thermal insulation with different technical characteristics.

For the roof, they usually create a layer of thermal insulation, 15 centimeters thick, and 10 is enough. Most often, walls with Ursa insulation with a sheet thickness of 5 centimeters are thermally insulated with two layers, and the roof with three.

Series of heat and sound insulation material

1) Ursa PureOne Insulation recommended for use by the Scientific Center for Children's Health of the Russian Academy of Medical Sciences. Clean White color insulation and a structure resembling natural cotton or wool is comfortable and pleasant to work with. The material does not burn, does not have a negative impact on humans and the environment during production and operation. They can be used to insulate the roof of a house, walls, acoustic ceilings and other noise-absorbing structures.

2) Urs production- insulation of the GEO series based on fiberglass determines the high performance properties of this type of heat-insulating material. The last 15 years has been especially popular in Russia. The insulation roll is compact and does not take up much space during transportation and storage. Typically, GEO insulation is purchased for work with attic and interfloor ceilings, for thermal insulation of balconies and loggias.

3) Insulation Ursa XPS is a rigid slab of extruded polystyrene foam. Freons are not used in its manufacture. Expanded polystyrene plates are not afraid of humidity and temperature changes from 50 degrees below zero to + 75?, so it is often installed in direct contact with water or open ground. There is a stepped edge on the edges of the boards for easy and quick installation. The connection is even and smooth, without gaps.

4) Ursa TERRA- it is a non-combustible mineral insulation with increased elasticity and moisture resistance. It can withstand temperatures up to 220 degrees without problems and modifications. One package contains from 10 to 12 sheets, with an area of 6 to 9 square meters. Application of Ursa TERRA insulation - external insulation along the frame or thermal insulation frame walls with brick lining.

5) Ursa SECO is a windproof material, a membrane with additional moisture-proof properties. It is used to protect Urs insulation and individual elements building structure. The membrane is placed with outer side close to the insulation.

Ursa insulation for walls

So moisture and steam penetrating from the room into the wall will freely go outside.
Bearing walls will not only be insulated, but also protected from sudden temperature changes, which will make them more durable.
The internal space of the building will not decrease after thermal insulation work.

Ursa M-15 fiberglass mats, Ursa P-15 plates or Ursa universal plates are especially good for wall insulation. For a thickness of 100 mm, two layers of insulation are sufficient.

On top of the insulation, the building is sheathed with siding, decorative panels or clapboard so that a ventilation gap of 2-5 centimeters remains.

If for some reason the house cannot be insulated from the outside, then the internal thermal insulation is done in almost the same way, only the insulation must be covered with a membrane for vapor barrier. Then wet steam will not damage the heater.

Even light summer cottage, insulated with Ursa materials, will turn into a comfortable cottage for year-round use.

Ursa insulation for roofing

The roof needs to be insulated in two cases.

Firstly, in order to insulate the ceilings, in order to maintain heat in the house itself. The ceiling will not freeze, heating devices will be able to work more economically, without wasting energy on heating the attic.
Secondly, to create a living space in the attic. In this case, the walls and ceiling of the attic are insulated, choosing desired view insulation.

Ursa heaters are very light, which helps to lighten the load on the building. They don't highlight harmful substances, do not burn and practically do not absorb water.

The elasticity and flexibility of Ursa materials allows them to fit snugly to all roofing elements without voids and gaps. Fiberglass materials provide not only heat, but also sound insulation.

Even the roof of the Bolshoi Theater during the recent reconstruction was soundproofed with Ursa PureOne insulation.

foil insulation material

Ursa insulation with foil, the price of which is slightly higher, represents perfect solution"2 in 1" for rooms with a high level of humidity. Baths, saunas, hammams with the help of Ursa M 11-50 are simultaneously vapor insulated and insulated.

One side of the Ursa rolled elastic insulation is covered with a layer of aluminum foil, which not only insulates the fiberglass mat itself from steam penetration, but also reflects heat radiation inside. The use of foil insulation simplifies installation, because additional vapor barrier is no longer necessary.

The construction time is reduced, therefore, the savings are significant.

Insulation Ursa - plate

In addition to rolled insulation, Ursa produces sheet types of heat-insulating materials.

The unique technology developed by the concern combines long intertwined fibers and an elastic binder in the structure of the insulation boards.

The plates do not break, do not crumble, retaining their shape and integrity during installation and long service life. The "spring effect" allows you to install the plates in the spacer, where they are fixed quite tightly. By the way, the compactness of the packages is explained by the same elasticity of the plates.

After removing the insulation, the material completely restores its thickness, size, and shape.

Ursa insulation, the characteristics of which allow it to be used in almost all types of construction, is produced in a wide range.

Buyers can choose special types of insulation for walls, roofs, floors. Special requirements for thermal insulation industrial facilities, pipes and other communication facilities.

For different types and series of Ursa insulation, the dimensions, the number of layers in the package and the thickness of the rolled or sheet material differ.

ursa insulation for walls are staple fiberglass processed using a special technology. The closest analogue of this heat insulator is glass wool. In the process of manufacturing the material, dolomite, soda, sand and other additives are used, kept in certain proportions. The resulting mixture is heated until melting, after which it is passed through special equipment. The output is a substance with a fibrous structure, in which the threads are glued together with a special composition.

To date, heaters Ursa for walls available in several versions. The most popular is the heat insulator from the URSA GEO series, made on the basis of fiberglass. In addition, the company produces URSA XPS insulation based on expanded polystyrene, obtained by extrusion. One of the brand's latest products is the Ursa PureOne insulation.

Currently Ursa wall insulation This is a guarantee that the necessary microclimate will be created in the room. The Ursa Geo product has become widespread due to the fact that only safe components are used in its manufacture. The ecological purity of the product is controlled throughout the production. There are no toxic additives in the finished insulation. Despite the fact that all insulation modifications are based on fiberglass, they may differ in the composition of the added components.

Wall insulation from the URSA XPS series have their own merits. Home hallmark this material is a small coefficient of thermal conductivity. The heat insulator is represented by solid and durable plates that can last for decades. This product is actively used for insulation of walls, basements and basements.

Ursa PureOne - warm and quiet

The new brand of Ursa PureOne insulation has both good qualities heat insulator, and serves as an excellent sound insulator. In addition, the material is easy to install, does not collect dirt and is stylized as natural cotton.

Another type of insulation Ursa Terra has increased moisture resistance and rigidity. It is actively used for wall insulation in private homes.

Application of Ursa for walls provides a comfortable indoor temperature throughout the year. The fiberglass line of the brand is distinguished by its increased ability to retain heat. Between the long and elastic fibers, multiple layers of air are formed, which provide high thermal insulation. The use of this material for wall insulation ensures that they do not freeze even in the most severe frosts. The thermal conductivity coefficient of this material is from 0.035 to 0.044, which is more than enough to create comfortable temperature indoors. The level of sound insulation of the heat insulator Ursa Geo is quite high. This is due to the fact that fiberglass effectively delays sound waves. However, the main advantage of the material is its environmental friendliness. The use of this insulation in a house or apartment will provide residents fresh air and healthy microclimate. For greater efficiency, walls covered with Ursa Geo insulation must be covered with a waterproofing membrane.

Benefits of ursa wall insulation

Another advantage of ursa fiberglass insulation for walls is that it is fireproof, because it is based on quartz sand, which does not burn. If there is a fire in the room, then the material will become an effective barrier to the further spread of fire. Over the years, the material practically does not lose its operational characteristics. The manufacturer guarantees the service life of the material for at least fifty years.

This thermal insulator is biologically stable. Since the material is based on inorganic substances, it is completely unattractive to rodents and insects. In addition, microorganisms, such as fungus, do not multiply in this heater.

Innovative wall insulation URSA PureOne created by a unique technology, which is now used only in Europe and Russia. The principle of creating the material is that acrylic is used as the main connecting element. It is a safe and chemically inactive polymer. Thanks to acrylic, fiberglass is not as prickly as in standard modifications. Wherein new material actually no dust. It is important to note that acrylic practically does not interact in any way either in air or with water, therefore it is actively used for warming hospitals and kindergartens.

The high soundproofing characteristics of URSA PureOne have been proven by tests at NIISF at Russian Academy Sciences. The role of the noise absorber here is played by elastic acrylic. This soundproofing material is much more effective than conventional glass wool. In addition, this heat insulator is more elastic and even has a spring effect.

Ursa XPS insulation made of expanded polystyrene is characterized by increased resistance to deformation. It perfectly withstands huge loads, which can be up to fifty tons per square meter. Like the rest of the brand line, this insulation is highly environmentally friendly. One of the main advantages of the material is its water resistance. The heat insulator can be used in conditions of high humidity, keeping the heat at the right level.

Construction and compositional composition of the walls of multi-storey buildings or one-story houses, as well as their thickness, are not able to ensure 100% safety of thermal energy inside the premises. Monolithic concrete or stone are considered cold materials, but in terms of strength they rank first among all materials used in civil and industrial construction. To turn these materials into energy-saving and warm structures, a multi-layer thermal insulation technology for building structures of any type is used. Thermal insulation is made for walls both outside and inside. When performing insulation, all SNiPs and GOSTs are observed, these two points are very important in the construction process.

All houses, structures or buildings made of stone require additional thermal insulation. Stone includes such materials as: brick (solid, hollow, silicate, hollow porous), aerated concrete blocks, foam concrete and fortan blocks, rubble stone, shell rock, kotylets and all types of cement and reinforced concrete products (monolithic slab structures, concrete panels and ceilings) .

Wall insulation, characteristics

There are the following types of wall insulation:

Styrofoam(insulation for walls expanded polystyrene) - is a modern polymer insulation of the latest generation. This product is used in almost all areas of construction and even in industrial production processes. Styrofoam grades PPT-25 and PPT-35 are used for wall insulation (outside and inside), attic balconies, loggias and mansards, as well as balcony floors. The dimensions of the foam boards are standard: 1000x500x50mm.

The material has the following qualities: low water absorption coefficient, zero level thermal conductivity, resistance to biological and chemical damage, windproof and soundproof properties, low weight, flexibility and ease of installation. The material is in the group of environmentally friendly products. Service life - more than 50 years. The price of this product is the most affordable, despite some disadvantages as a flammability class.

Mineral wool (stone wool or glass wool) is a heat and sound insulating material widely used in the insulation of buildings of any purpose, and especially walls (external and internal), balconies and loggias. The internal and external use of the insulation justified its quality due to the physical and technical characteristics:

In insulation work (eg wall insulation in a panel house), mineral wool with thermal conductivity: 0.034-0.037 W / mK and flammability class NG (non-combustible) is used. It is possible to work with material at temperatures from -60ºС — to +220ºС. This roll insulation for walls has following sizes: 1000x600x50mm, 7000x1200x50mm, 9000x1200x50mm, 10000x1200x50mm, 10000x1200x100mm, except for rolls, cotton wool is produced in slabs.

Brands of mineral wool used for wall insulation: Ursa, Izovol, Knauf, Rockwool, TechnoNIKOL, etc.

polyurethane foam- a kind of plastic, has a cellular-foamy structure. The cell space is filled with air and occupies 90% of the total mass of the product. PPU has a high level of resistance to various chemicals, does not absorb water, excellent heat and sound insulation, has a low weight and a high level of adhesion to all types of work surfaces: concrete, glass, wood, steel, brick, painted surfaces. With material it is possible to work at a temperature of 100 degrees. Operating period - up to 30 years.

PPU (polyurethane foam) is widely used in the process of insulating walls and frame balconies, as well as for insulating buildings with complex configurations. The zero level of thermal conductivity and the elasticity of the product are exactly what you need to insulate walls, balconies, attics and attic space. The seamless process of using this product and its perfect adhesion creates a truly hermetic seal. No need to ask the constant question: “what insulation is better for thermal insulation?” - PPU is an excellent coating for walls both outside and inside. This material is a guarantee of excellent vapor barrier and, first of all, waterproofing. The only negative is the high cost.

Extruded polystyrene foam– latest generation material, made in a special way technological process. For wall insulation, the brand of extruded polyurethane foam Penoplex and Technoplex is more often used. In the manufacture of Technoplex, graphite is used in the form of nano-sized particles. Nano-sized graphite increases the strength of the material and increases the energy saving of the product.

Penoplex (insulation for walls penoplex) - has a high energy saving coefficient, zero heat loss, excellent sound insulator. In addition to wall insulation, this material is widely used in the insulation of balconies, loggias, floors, basements and other building structures. When installing a "warm floor" - penoplex is an essential material. The coefficient of thermal conductivity is 0.0029W/(m°C). Comparing Penoplex with foam panels, mineral basalt wool or glass wool, it surpasses them in terms of energy saving. Moisture resistance is equal to 0.2%, the strength factor is 200-500kPa. Not subject to destruction by mold, chemical substances and rodents. The boards are quickly assembled due to their flexibility and low weight. The product corresponds to the flammability class - G1, G4. Almost all brands of extruded polystyrene foam are endowed with such characteristics.

Liquid thermal insulation. For example, alphatec is a liquid-like thermal insulation of the latest technological progress in the field of insulation. In production technology this material included polyacrylic system with the formation of many ceramic bubbles. The bubble system is filled with vacuum and it is this technical side that acts as an insulating component.

Material Features:

heat insulator for external and internal use,
ultra-thin insulation for pipes of any purpose and diameter,
excellent material that prevents corrosion and other metal destruction,
energy-saving product with zero heat loss,
the material prevents the formation of condensate,
frost protection,
resistance to sudden temperature changes,
reducing the weight of the structure,
preservation of space,
in addition to elasticity and energy saving, the product has aesthetics.

"Heat mirror effect" Alfatek - is to reflect the heat flow received from the coolant or heat reflector and keep the heat in itself. This ultra-thin insulation interrupts the contact of the base with the flow of cold entering the room from the outside, that is, from the street. The thermal conductivity of the material is 0.001W/m°K.

Alfatec thermal insulation (liquid wall insulation) anti-corrosion protection of all metal surfaces with coverage for all hard-to-reach places, which cannot be covered with other types of heat insulators. The put layer of isolation is not exposed to destruction from the side of the atmospheric phenomena and chemical substances. The concentration of paint does not affect the reduction in the degree of insulation, the main thing is uniform application and the absence of cold bridges.

The appearance of the Alfatec product is similar to regular paint based on water and acrylic polymers. In addition to pipe systems and metal structures insulation is used to insulate all types of surfaces: brick, stone, concrete, etc. Before application, careful surface treatment is necessary: dust removal, degreasing and drying. For work on metal, priming or other treatment with anticorrosive agents is not required, the paint of the insulator acts as a corrosion preservative.

Other heaters are also used: ecowool, warm plaster, polyethylene foam (penofol, termaflex, isolon, energy flex), foam glass and others.

How to insulate walls?

For thermal insulation of such materials, there are three options:

Option I - insulation for the walls of the house is mounted around the entire perimeter interior spaces inclusive, attic, balcony and loggias (walls, floor, stream, and on the balcony, in addition to the above, there is also a parapet);
Option II - the insulation is placed in the thickness of the construction cake (when pouring concrete, thermal insulation such as expanded polystyrene, BSA or polystyrene concrete is placed right in the middle of the pour);
Option III - insulation of the structure from the outside (hinged ventilated facades as insulation for walls - foam plastic, extruded polystyrene foam, stone wool or glass wool, expanded polystyrene concrete and others).

All options have their pros and cons for internal insulation the disadvantage is the formation of condensate, this is a clear and actual problem modern construction and thermal insulation.

Masonry in the form of a "pie"

The construction “pie” consists of the following layers: the first layer is load-bearing walls, the second layer is cement or mixed plaster and heat-insulating material, the third layer is the finishing facade cladding, consisting of: primer, glue, building cladding mesh, finishing plaster and decorative finishing material .

Bearing walls are made of durable masonry or filler material, additional connecting and reinforcing elements. Stone or concrete are two durable building and masonry materials used in the construction of houses from the base or foundation to the attic. The load-bearing walls account for the entire mass of the building, the operational life of the house and the strength to withstand the additional weight added by means of other materials and devices depend on their strength: reinforced concrete stairs and flights of stairs, roof structure with its constituent materials, plumbing network, heating equipment and all contents of residential premises (furniture, household appliances and plumbing equipment etc.). When planning a future building, all these nuances are calculated to the smallest detail.

As for thermal insulation, here you can list a whole list of heaters: polystyrene foam, extruded polystyrene foam, mineral (stone) basalt wool, fiberglass wool, polyurethane foam (PPU), liquid thermal insulation, warm plaster, cellulose boards, sandwich panels and others thermal insulation materials. Insulation according to the technology is superimposed on an even layer of plaster, that is, before the walls are insulated, the surface is plastered.

The final or finishing layer is carried out in order to seal the previous layers - the load-bearing wall and insulation, as well as to decorate the walls from the outside of the building. Wall insulation from the inside is carried out using a similar technology, with the exception of finishing plastering.

Insulators have almost the same coefficient of thermal conductivity, due to which the thickness of all types is the same, the calculation of the thickness of the insulation for walls is carried out from the point of view right choice material with a high level of energy saving inside the building. If construction is carried out in an area with a harsh climate, a double layer of insulation is used, regardless of whether it is mineral wool or expanded polystyrene. Compared to basalt wool, extruded polystyrene foam or simple foam plastic adheres tightly to the base without forming cold bridges, but is inferior in flexibility to stone wool.

Vapor permeability plays an important role in the thermal insulation of walls, the higher the coefficient of this coefficient, the less likely it is that condensation will form. Condensation leads to the destruction of all composite components of the layered masonry, thus shortening the operational life of the building.

Fire safety ranks first among technical requirements during construction and insulation. Despite the importance of this item, the foam is still widely used because of the cost and ease of installation. Styrofoam is 5 times cheaper than mineral basalt wool, which is why it is allowed in the process of performing thermal insulation.

According to the agreement SP 23-101-2004 “Design of thermal protection of buildings”, using foam plastic (foam plastic wall insulation technology), all window openings and areas surrounding windows are insulated with non-combustible materials - mineral wool, glass wool and other non-combustible materials. This technology "saved combustible" foam from the list of prohibited products for thermal insulation of buildings and houses.

Fasteners are plastic dowels or basalt-plastic tapes. Tapes are mounted with a step of 60 X 50 cm from each other. The fastening system or fixing the insulation to the wall is quite durable, with a service life of up to 50 years. The entire finishing layer rests only on the foundation of the building.

Attention! When performing work on wall insulation from the outside, it is necessary to properly close the lower space in the area of \u200b\u200bthe foundation and the three-layer cake.

To avoid devastating consequences from the heat-insulating process, ventilation of the walls is carried out or hinged ventilated facades are installed. Due to the space between the insulation and the outer wall, as well as the installation of ventilation holes, an obstacle is created for the formation and settling of moisture inside the construction “pie”. Thus, the constantly ventilated layer cake will serve for many years without complaints from consumers.

After the completion of construction, it is already known what material to insulate the walls with, because these facts are included in the project plan, and for secondary housing, what kind of wall insulation is needed, how to choose them ?! A civil engineer together with a technologist, when examining such structures after a full examination, will be able to give an accurate technical answer to this sore point. There is nothing complicated here - the main thing is to repair the building, and then everything is done according to the specified scheme of external thermal insulation.

Mineral basalt wool is an ideal insulation for walls under siding, in this case it is necessary to perform phased installation and proper ventilation of the facade. IN panel houses the walls from the inside are very cold, even in the case when the external insulation is 100% complete, there is a need for insulation. It is urgent to install wall insulation under the wallpaper, then the walls will become warm and dry when touched.
