Profiled sheet or ondulin which is better. What is better for the roof: ondulin or corrugated sheeting

The modern market for roofing materials allows you to choose a coating to suit every taste and budget. And there are two very popular ones in it, seemingly similar, but completely different in essence materials - profiled metal and bitumen sheets.

They cost approximately the same, look similar from a distance, have a recognizable geometry, and therefore often confuse future home owners: where to choose? Especially considering the conflicting customer reviews.

In this case, let's take a closer look at those situations where it is more preferable ondulin or corrugated sheeting: which is better for the roof of a residential and cold attic of a house, northern or southern region, and also what exactly pleases and upsets in both types of roofing.

Corrugated sheeting and ondulin are really similar in appearance, because both are long sheets bent on a machine into a certain profile. But in terms of raw materials, both materials differ radically:

The basis for the production of ondulin is the most common waste paper, which is processed at the plant. Cardboard in the finished sheet is from 400 to 500 grams per square meter. As a result, such a mass looks like a porous material and represents fibers from recycled synthetic, textile and wood raw materials.

And not everything is as simple as many people think. There are certain quality requirements for such raw materials: there should be no lumps, cracks or tears in the cardboard. Only smooth ends and a uniform layer, which can in the future ensure uniform and high-quality impregnation with molten bitumen. In addition, the cardboard must have some tensile strength and a moisture content of no more than 6%.

But corrugated sheets today are produced on the basis of cold-rolled but hot-dip galvanized steel. In production, zinc is applied to a steel sheet with a thickness of 0.14 to 1.5 mm in a layer of about 30 micrometers. Galvanizing itself reduces the cost of the material, but provides a good level of corrosion protection. The finished sheet has fairly high mechanical strength and bending rigidity.

Of course, the very comparison of cardboard and steel sounds funny. How can you even talk about something like this seriously? This is exactly what many people think and are mistaken. Indeed, in fact, cellulose is rightfully considered one of the most durable materials in existence. Look at the old wooden houses that have been standing for the second century, and they are not afraid of either wind or rain.

It's all about these flexible and durable fibers created by nature itself - cellulose. And strong wood in practice can withstand a much greater load than thin metal, like a tin can. Because it’s all about the technical characteristics of the finished product.

By the way, e There is such a subtype of corrugated sheeting as metal slate - this is also a thin profiled metal sheet, which differs only in its wavy shape. It looks more harmonious on the roof than the angular traditional metal profile, but there are still many questions about its high-quality fastening and protection against leaks. In appearance, such a roof can no longer be distinguished from ondulin from afar.

Load calculation: when strength is a priority

According to modern European slate manufacturers, their roofing covering can withstand loads of up to 960 kg per square meter. But in the case of corrugated sheeting, you will not find a clear answer anywhere, because everything depends on its brand and intended purpose.

The whole secret is that The height of its corrugation, unlike metal tiles, can be very different - from 8 mm to 150 mm. And the higher the wave, the stronger the material, and the more resistant it is to deflection.

And it is precisely based on these stiffening ribs that the metal profiled sheet is divided into separate categories:

Only roofing and load-bearing corrugated sheeting are suitable for roof construction. Moreover, for example, if you want to play it safe, you won’t be able to do anything with ondulin – it always comes in the same format.

But corrugated sheets can be purchased with the corrugation height chosen at your discretion, and provide the roof with almost any strength. After all, its load-bearing appearance is even used as a basis for covering an entire floor!

Therefore, if you are faced with the question of whether the roof of your house or the same veranda will withstand a heavy snowy winter, when your region is famous for just such a climate, then it is better to give preference to corrugated sheeting.

All elements: resistance to mechanical damage

There is also an interesting observation about ondulin: in some regions of Russia it can be damaged by woodpeckers who catch flies in the fall. There are reviews that these small-packed birds literally break through this coating. Although ondulin itself can restore its shape, such damage does not bode well.

You've also probably heard that Euro slate bends underfoot. This is partially true, and this only happens in unbearable heat of more than 40 degrees. In this case, under direct sunlight, it can soften so much that it will actually sag from a person’s foot and will not even recover.

Then the natural question is asked: why even walk on the roof in such heat? In fact, there are reasons: to fix the antenna, remove a mischievous cat, return a flying drone.

Don't forget about wind loads too. Yes, and Ondulin and corrugated sheets have similar geometric surfaces and, like solid materials, have high windage properties. But corrugated sheeting is still torn off roofs more often. Why?

The fact is that, due to this very problem, ondulin manufacturers produce special nails with wide heads and threads on the rod. The nail is driven deep into the sheathing, where it sits quite firmly, and the wide head of the fastener holds the sheets well. But with corrugated sheets, standard screws are used. And their cap is not as wide as that of ondulin.

Heat shielding: comfort of living under a roof

This is how a bitumen profiled sheet fundamentally differs from a metal one:

Bitumen is a natural resin, and ondulin has always had and will have a certain flexibility and viscosity at high temperatures. Therefore, on the hottest summer days it softens a little, which causes inconvenience, if only because walking on such a roof is temporarily not allowed. But at the same time, bitumen sheets themselves have low thermal conductivity, and therefore do not transfer heat to the under-roof space.

Thanks to this, the attic or residential attic with such a roof is cool in summer and warm in winter. The same cannot be said about a metal roof, which heats up in direct sunlight in a matter of minutes, and in winter turns into ice. At the same time, the presence of a layer of insulation under the sheets only partly solves the problem.

Protective coating: weathering

Modern ondulin on the front side of the sheet is covered with a protective and decorative paint layer based on light-resistant pigments and polymers. High-quality ondulin is also coated with high-strength acrylic, which significantly increases the durability of the sheets and protects them from weather conditions. Thanks to all this, all the dirt that gets on the roof surface can be easily removed by the first rain or sliding snow.

By the way, the surface of ondulin is rough, and therefore by itself holds a cap of snow on the roof (additional thermal insulation, by the way). But for corrugated sheeting you need to install special snow guards, and the more, the better:

As you can see, this is very close in properties to the perfectly smooth surface of a corrugated sheet, on which dirt almost never lingers.

Condensation problem: rain under the roof

And not only do the drops collect on the inner surface of the panel, but they also roll directly onto the walls. And therefore, when laying insulation, it is necessary to create a ventilation gap and provide ventilation so that all moisture leaves the roof and does not spoil the thermal insulation.

At the same time, ondulin does not heat up that much, and therefore does not condense, and there is no question of such problems. True, it softens from the sun's rays and some residents even detect the smell of bitumen.

But, in fairness, we note that there are brands of corrugated sheets that are produced with a special anti-condensation coating on the inside. This decision was literally revolutionary. The fact is that before sale, corrugated sheets often have to be stored in cold rooms, and since the metal cools faster than other materials, even from the cold air there is something to condense on its surface.

The anti-condensation coating itself is something like a pile that holds small drops on itself, preventing them from collecting into small streams. And when temperature conditions return to normal, the coating will dry on its own in the air flow:

Interestingly, the polymer film on such corrugated sheeting also protects the metal itself from negative chemical influences, of which there are many, for example, in industrial buildings.

All this is important for industrial construction. After all, the mere use of accompanying material in the form of additional boards and waterproofing increases the labor intensity of all work at least twice. As is their cost.

Until recently, condensation on corrugated sheets was dealt with using standard technological solutions. Rolled waterproofing or roofing membrane was spread over the sheathing, a gap was made, then the roof covering itself was fastened along the counter-lattice. Moisture from the air condensed on the inside of the metal sheet, then dripped onto the waterproofing and simply flowed down it if everything was done correctly.

This is a simple physical phenomenon: there is always water vapor in the air, and when heated, it comes into contact with a colder surface and simply cools down, turning into droplets, at a moment called the dew point. Moreover, this process occurs every day, every night. Considering that during the day the metal roof is heated by the sun and heats the air under it.

If it now seems to you that corrugated sheeting is definitely inferior to ondulin, let’s honestly and impartially consider the important disadvantages of the latter:

Let us add the following observation regarding color fading. G glossy ondulin becomes beautifully matte after a year or two, lighter in tone and most buyers even like it.

Transportation and installation: pitfalls

Ondulin is quite easy to transport due to its light weight (up to 6 kg). You've probably seen a stack of bitumen sheets on the roof of a car or in the trunk. But, due to the fact that ondulin can be bent, putting it in the trunk will not be a problem, but corrugated sheeting can only be transported on the roof of a car, or even using special transport.

Further, if it is difficult to scratch ondulin sheets during loading and unloading, then the corrugated sheet can begin to rust from the slightest damage. What is the disadvantage of corrugated sheeting? In the process of transporting parts to the construction site, you literally have to shake over metal sheets.

After all, even if you then treat the scratches with paint or sealant, it will become noticeable and the original appearance of the roof will be lost. That’s why such sheets are also lifted onto the roof with extreme caution.But you can even throw ondulin onto low buildings by hand.

Unfortunately, some of the typical problems with corrugated sheets arise even before installation:

Installation Features: Geometry Problems

There is a significant difference in the installation of corrugated sheeting and ondulin. Thus, ondulin can be laid on roofs with a slope of at least 14 degrees. But corrugated sheeting, depending on the height of its corrugation, is even suitable for constructing a load-bearing floor for a house. To some extent, certain types of corrugated sheeting are much more durable and stronger than ondulin (which cannot be said about metal tiles).

When the roof is perfectly flat, both bitumen and metal profiles will look decent on it. But if it turns out that the slopes are not even rectangles, then things are bad.

To check this, you do not need to make cuts in the eaves and gable boards. It is enough to measure the diagonals, and they should match. If it turns out that one diagonal is larger than the other, you have problems.

After all, metal sheets, unlike bitumen ones, cannot be stretched, compressed, or “pulled” to the desired location. You will have to sacrifice another sheet to cut out two triangles from it, and place each on the sides of the slope - where it will be empty and where the error in the rafter system will be clearly visible. What the roof will look like after this is another question.

But with ondulin, these problems can be easily solved with your own hands:

By the way, ondulin is quite flexible and by itself slightly eliminates the problem of sloppy sheathing. But don’t let this reassure you, because we are still talking about building a roof. At the same time, with corrugated sheeting, any error will be clearly visible.

This suggests that even an unqualified builder is able to cover a roof with ondulin quite efficiently, just by carefully studying the instructions and advice on our website. This is an important point, because there really aren’t that many trained, experienced roofers. And the more complex the installation technology, the higher the risk that it will be messed up.

Let's also consider such an important point as cutting roofing sheets. You still need to try hard to ruin an ondulin roof, and you can even cut bitumen sheets with an ordinary stationery knife. The only thing is that you can cut Euro slate in the summer only in the morning or evening so as not to soften it.

But cutting sheets of corrugated sheets in an open area is not a difficult task. True, if you do this in direct sunlight, the metal will heat up to an unpleasant temperature, giving harsh radiation directly to working people.

One of the most pressing problems is mounting the fastener. It only takes a little extra force to damage the rubber gasket on the screw. But in the case of bituminous material, you can safely work with a hammer - the base is soft and pliable, and the edges of the cap are more likely to slightly bend it than to deform themselves:

This is an important point. After all, it is precisely because of small jambs in the installation of corrugated sheeting that 99% of problems arise with it in the future: it corrodes, leaks and loses its appearance!

You should also take into account the fact that, if necessary, the corrugated roof can be carefully dismantled and moved to a new location. But in the case of ondulin, you will have to throw it away, because... the nails in it, of course, can be pulled out, but the appearance of the ondulin itself will not be the same - there will be torn holes in the places after fastening.

In total, the manufacturer of ondulin, like corrugated sheeting, produces all the necessary additional elements for the roof.

Ondulin as a roofing material

Ondulin is ordinary cardboard that is impregnated with bitumen under high pressure. This impregnation allows you to completely protect this coating from moisture and gives it elasticity, strength, and ensures ease of installation.

Pros of ondulin

Ondulin is very simple and flexible to install, this is a huge plus for roofs of increased complexity. The material is famous for its service life, which, if used correctly, reaches 25 years; it can also easily withstand snow thickness of up to half a meter. This coating does not allow noise to pass through at all, which means that neither rain nor hail will disturb the owners with their noise. The coating does not require additional vapor barrier, which significantly reduces the buyer's costs.

Cons of ondulin

As for the disadvantages of this coating, the biggest disadvantage is that it supports combustion well due to the fact that it is impregnated with bitumen (it can withstand temperatures of up to 110 degrees - the ignition temperature, and has a fire safety class of KM5). If a fire occurs, it will be very difficult to extinguish, so this coating is not suitable for homes with stove heating. It is not recommended to lay the material on a roof with direct sunlight, as it quickly fades and loses its former color. Covering sheets are produced in one standard size – 1950*950 mm. This, in turn, is not very convenient, since when covering the roof a large amount of scraps remains, which is completely uneconomical. The coating has a rough surface, due to which the snow will not slide off on its own in winter.

Corrugated sheeting as a roofing material

The corrugated sheet is a steel sheet, the thickness of which is about 1 mm. The sheet contains waves of different sizes, due to which this material acquires a certain rigidity. The upper part of the sheet is treated with a thick layer of paint.

Advantages of corrugated sheets

As for the advantages of corrugated sheeting, they are much greater than those of the first option. The service life of the material is more than 50 years; it requires absolutely no maintenance. Due to its smooth surface, neither dirt nor snow lingers on the sheet. Due to its strength, it can easily withstand the weight of a person (depending on the size of the stiffeners), and, consequently, a large amount of snow. The material is completely non-flammable, it can be safely used for roofs with stove heating.

Cons of corrugated sheets

Speaking about its disadvantages, I would like to note that the sheet consists of metal, and metal, as you know, is subject to corrosion. If the top layer of the material is suddenly damaged (during installation or from physical impacts) and the paint peels off, then over time rust will appear in this place.

Comparison: corrugated sheeting or ondulin - which material is better.

Both materials have their pros and cons.

When choosing a coating, first of all you should pay attention to

• weather conditions - the first option is more suitable for dry and warm climates, and the second - for more severe and snowy ones;
• flammability of materials and operating conditions;
• appearance and aesthetics.

It is cheaper to use corrugated sheeting as a roofing material (compared to ondilin). Especially if comfort is not in the first place! Corrugated sheeting is very often used for non-residential buildings - sheds, garages (just not under the bedroom window), pens, sheds. If the question is: which roofing material is better for a shed or garage, then you cannot find better than corrugated sheeting.

Also, if you are comparing whether ondulin or corrugated sheeting is better, pay special attention to the combustion properties of the material. If you use a stove for heating in your home, then you should stop using ondulin! We pay special attention: we strongly do not recommend ondulin for use on the roof of a bathhouse - it is not safe!

If you are focused on comfort, and the “burning” characteristics are not important to you, then ondulin is well suited because it is one of the most noise-absorbing roofing materials!

Review of materials

Any building or structure has a roof. The roof provides warmth, comfort, and protection of the room from natural phenomena.

The technology for constructing a roof involves covering it with roofing materials.

Pros and cons of corrugated sheets

Corrugated roofing is quite strong and reliable, and has properties that can be decisive when choosing a roof.

Color palette coatings have a wide range, which allows you to give the building an original design.

Ease of installation. Possibility of installation without the help of special devices, lightness of sheets of material.

Positive traits

• fire resistance;
• good water resistance;
• resistance to atmospheric influences;
• good anti-corrosion properties;
• affordable price.

Negative qualities

• influence of atmospheric influences (rain, hail) on the level of sound insulation;
• damage to the roof can contribute to corrosion of the material;
• the ability to critically heat up when exposed to high temperatures;
• condensation formation.

When installing corrugated sheets, the sheets should be laid correctly to avoid water permeability of the building roof.

Ondulin or corrugated sheeting - which is better for the roof of a private house?

Comparing the two roofing coverings, you can see that they have many positive qualities:

• affordable price;
• ease of installation;
• availability in construction markets ( popularity);
• sustainability to weather events, precipitation;
• possibility to choose a color scheme;
• enough long service life.

What is cheaper, ondulin or corrugated sheeting? Ondulin costs only 5% more, but its transportation is cheaper than transportation of corrugated sheets. As a result, the price of the final product is approximately the same.

When considering the features of each material, it is more important to decide which particular structure needs to be covered with a roof; it is important to take into account its intended purpose. Ondulin is often used to cover residential buildings: it is convenient to install it on complex and hard-to-reach roof areas due to the good flexibility of the material. To correctly calculate the number of ondulin sheets for the roof, use.

Corrugated sheeting is often used for warehouses, grocery stores, tents, stalls. It is more convenient to cover large roof areas with corrugated sheeting, given the large width of the sheet. Ondulin is easy to install on pitched roofs.

Corrugated sheeting and ondulin are very popular, and the decision to use one or another coating is made based on personal preferences.

What is better ondulin or profiled sheet? It turns out that corrugated sheeting and euro slate do not have significant differences, but some factors may influence the decision on the choice of material, for example, the sound insulation of corrugated sheeting or the heat resistance of ondulin.

Alternative roofing coverings

With a wide selection of roofing materials, it is not always possible to choose ondulin or corrugated sheets. The market is quite many alternative roofing materials, which can be used to cover roofs:

• . The material is quite durable, but has too low a level of sound insulation;
• slate. It is distinguished by its low price and durability, but due to the asbestos content it cannot be environmentally friendly;
• ceramic tiles. Quite heavy and expensive material, but it has a beautiful design and a large assortment;
• seam steel roofing. Cold, poor sound insulation, but quite flexible and fireproof;
• soft roof. Durable, beautiful design, but very flammable and fragile in the cold.

These and other types of coatings can be used to equip the roof of a building. Each of them has its own styling features, functional properties, price level, durability and undesirable qualities. Taking these indicators into account, you can choose the right roofing covering that will last for many years and protect the building from external influences.

Conclusion

Whatever variety of roofing materials is presented on the market, ondulin and corrugated sheets are the most common roofing materials used today. Their popularity is due to their good performance, price and attractiveness.

In contact with

When designing a new building, quite often you have to decide on the choice between ondulin and corrugated sheeting as a roofing covering. In order to make the most optimal decision about whether ondulin or corrugated sheet is better, you will need knowledge of the basic characteristics of both materials.

Ondulin

To make ondulin (or flexible slate), ordinary cellulose cardboard is used, where bitumen and heat-resistant resins act as impregnation. Giving the desired color is achieved using mineral dyes.

As for the name of the material, this was the name of the French company that was the first to produce flexible slate 50 years ago. If we talk about our country, then acquaintance with ondulin occurred approximately in the 90s of the 20th century.

Profiled sheet

The coating is made on the basis of corrugated steel sheet. Its waves have a height of 20-80 mm, which allows the material to be given a high level of transverse rigidity. To protect the metal surface from moisture, a single-layer or multi-layer anti-corrosion coating is used.

It can be made from:

• Zinc. Galvanized profiled sheets are most often used to create temporary fences and roofs in warehouse and industrial buildings. The unpopularity of the material in private housing construction is explained by the fact that it is produced in only one color.
• Polymer. To improve performance characteristics, galvanized profiled sheets in this case are additionally coated with a polymer layer. This increases their mechanical strength, ability to resist corrosion and decorative effectiveness.

Comparison of two materials - pros and cons

Cost - which is cheaper

The first task that one has to face when choosing between two roofing options is to determine what is cheaper - ondulin or corrugated sheeting. As of March 2017, a comparison of prices leads to the fact that ondulin is approximately 30% cheaper.

It remains to be seen whether the higher price of profiled sheets is justified by their performance characteristics.

Service life of corrugated sheets and ondulin

Next, it is important to determine which coating lasts longer, ondulin or corrugated sheet. Manufacturers of flexible slate usually provide a guarantee for their product of 40 years or more. As for the profiled sheet, the service life is indicated somewhat longer - 50 years. In any case, both coatings can provide the roof with fairly durable operation.

However, you should know some nuances:

1. Some varieties of ondulin can effectively withstand moisture for only 15 years, and only if the installation technology is followed.
2. Some time after installation, ondulin fades under the influence of sunlight, but this does not reduce the service life of ondulin.
3. The actual durability of the profiled sheet is largely influenced by the thickness of the protective zinc layer. In an effort to win a competitive race, this is where many corrugated sheeting manufacturers often try to save money.
4. When cutting corrugated sheets with an abrasive tool, you should keep in mind that in this case its corrosion protection is violated. This can cause rust along the cut line.

Therefore, it is not possible to determine which is better for the roof - ondulin or corrugated sheeting, by comparing their service life. There is approximate equality here, since this indicator is influenced by many additional factors.

Strength characteristics - which is better for the roof

It is very important how the roof will be affected by snow load or high wind. If there are other outbuildings or trees on the site, then there is always a risk of a piece of neighbor’s siding or a tree branch flying onto the roof.

The popular brand of flexible slate “Smart” has the following characteristics:

• The maximum permissible snow load is up to 960 kg/m2.
• The maximum permissible wind speed is 175 km/h.

The accompanying documentation for profiled sheets does not provide such information.

1. Winds with a speed of more than 117 km/h are called hurricane winds. It is capable of causing large-scale destruction, damaging houses and uprooting trees.
2. The snow load on roofs in our country usually does not exceed 600 kg/m2. Ondulin roofs are always pitched, and the seams are usually not waterproofed.

At first glance, flexible slate wins here.

But one should refrain from hasty conclusions:

• Steel sheets are an order of magnitude stronger than bitumen-impregnated cardboard. For example, ondulin fences can only keep out small pets. As for fences made of profiled sheets, such structures do an excellent job of their duties, having good anti-vandal characteristics.
• The ability to withstand snow and gusts of wind indicated for flexible slate is also characteristic of profiled sheeting. The main thing is that in both cases a continuous sheathing is used.
• During severe frosts, ondulin becomes fragile. And if some heavy object falls on such a roof, it can cause irreparable damage. In the case of corrugated sheeting, everything is usually limited to a small dent. The pros and cons of a corrugated roof make it a winner in terms of strength.

Transportation

Next, you need to compare ondulin and corrugated sheeting according to the features of its transportation from the place of storage or purchase to the construction site. This criterion is directly dependent on the size of the sheets and their weight: the lower the weight, the more convenient the transportation.

Here metal products are inferior to ondulin:

• The weight of flexible slate measuring 195x95 cm is 6 kg.
• Corrugated sheeting has a standard width of 120 cm, but the length can be up to 6 m. The weight of a linear meter of the lightest type of material with a thickness of 0.4 mm is about 4 kg.

Installation

As for installation work, the advantage is given to the material whose sheets are large in size. This makes it possible to reduce the number of joints while increasing the speed of work. The significant length of the profiled sheets allows in many cases to completely cover the roof slopes without using longitudinal overlaps.

Metal products have a couple more advantages:

1. Cheap sheathing. To cover the roof with profiled sheets, sheathing is installed in increments of 30 cm. With an increase in the thickness of the metal and the height of the profile wave, the permissible pitch of the sheathing also increases. The frame for the ondulin must be solid, with virtually no gaps: this implies high costs for its sheathing. This criterion can be attributed to the comparison mentioned above, which is cheaper - ondulin or corrugated sheet.
2. Self-tapping screws can be installed at the bottom of the wave: due to the use of rubber press washers, the connections are airtight. To fasten ondulin, it is allowed to use only roofing nails, and the place where they are driven can only be at the top of the wave. This type of fastening is not as durable.

Noise level

Results

Each person, having compared ondulin and corrugated sheeting, will be able to come to certain conclusions. If the strength of the roof covering is considered a priority, then profiled sheets have an advantage. At the same time, ondulin has its advantages, the main ones being the lightness of the material and the ease of its installation.

The roofing material must be reliable, moisture-repellent and have a beautiful appearance. It is desirable that it can be easily laid, and if necessary, it is possible to replace only one deformed section, and not the entire roof.

Modern roofing materials such as ondulin and corrugated sheets meet these requirements. The question often arises, which one is better to choose; without familiarizing yourself with their advantages and disadvantages, it is difficult to understand. To make the choice easier, we will provide a comprehensive answer to this question.

Pros and cons of corrugated sheets

It is a sheet of metal that has increased rigidity. It is based on sheets of galvanized steel, the wave-shaped profile of which is made on rolling equipment. Its sheets are coated with a protective anti-corrosion compound, then a layer of primer is applied. Varnish is applied to the outside of the material, and polymer is applied to the inside.

The rigidity of the corrugated sheet is ensured by trapezoidal ribs. The material is used not only for roofs, but also for arranging fences and walls of buildings.

It has found such a wide range of applications due to its positive aspects:

• Light weight, facilitating installation work.
• Affordable price.
• Durability. If the protective layer remains intact during its stay on the roof, the material can last for half a century.
• Environmental friendliness.
• A small number of material joints ensures high tightness of the entire roof.
• Wide range of colors.
• High fire safety. Corrugated sheeting is not flammable and does not support fire.
• Protection from rot and corrosion.
• Versatility. Corrugated sheeting can be mounted on roofs of any complexity and slope. It is used for buildings for various purposes.
• Beautiful appearance.

The disadvantages of corrugated sheets include:

• Formation of condensation on the surface of the material.
• Low degree of sound insulation, which threatens the presence of noise during precipitation.
• Roofs with curves and complex angles can cause problems.

Pros and cons of ondulin

This material is also called Euro slate; it quickly won its admirers; many prefer it because of its aesthetic appearance. A roof covered with it looks attractive; its wavy sheets, imitating classic slate, add harmony. It was invented more than 50 years ago for residential buildings; it covers canopies, gazebos, and private cottages. It makes any building look solid.

Its production uses cellulose fibers, which are pressed and then impregnated with bitumen. Afterwards, the manufactured sheets are given a wavy shape. They are covered with paint and resin on top.

Due to the small thickness of the sheet, this material is relatively lightweight, which makes it easier to transport and lift to the roof of the building. In addition, due to this, ondulin can be cut with a regular hacksaw; it bends perfectly, so it can be used for roofing surfaces of any complexity.

Due to its positive properties, ondulin can compete even with tiles; its strengths include:

Like any other material, ondulin has its downsides:

What's better?

Each of the materials considered is good for roofing, even with its drawbacks. The choice of one of them is primarily based on the preferences of the owner of the house. But there are several nuances of these materials, if you compare them according to certain characteristics.

Ondulin can only be used for roofs, while corrugated sheeting has a more diverse application. A roof and a fence made from it in its native color will look very interesting in one area. But what is better is ondulin or metal tiles, this information will help you understand in detail. But what is better to cover the roof with corrugated sheets or metal tiles?

On the video, what is cheaper ondulin or corrugated sheeting:

Ondulin differs from corrugated sheeting in its greater plasticity, so it is better to prefer it for complex roof structures; it is excellent for fastening in various hard-to-reach places. There is no need to make a continuous sheathing underneath it, as is the case with corrugated sheeting; it has higher heat and sound insulation properties. But galvanized material is not subject to combustion and ultraviolet radiation, it is more airtight, but is susceptible to corrosion at the attachment points.

The cost and service life of ondulin and corrugated sheets are the same, the weight of their sheets is practically the same.

When choosing between these two roofing materials, the main thing is to take into account the features of the structure being built, the degree of complexity of its roof, the presence of an attic floor in the house and the structures located near it. Durability and performance properties are guaranteed only by high-quality materials, so when purchasing them you need to check for a certificate.
