Today, few developers will not pay attention to the multi-colored elements of ondulin. The products have firmly conquered the market thanks to their advantages, but there are also disadvantages that you should also be aware of. The characteristics of ondulin are often discussed, it is not for nothing that the material is called euro-slate, paying tribute to aesthetics and practicality. Let's look at the advantages, disadvantages and types of coating in more detail.

The roof covering was invented over a century ago and today the principles of production have been preserved. In the manufacture of products, cellulose fiber is used, which goes through the processes of heating, pressing and shirring at a temperature of +120 C. After that, the elements are coated with paint and impregnated bituminous compositions with polymer additives.

In fact, ondulin is a kind of slate, but with higher practical and quality characteristics. In the production process, an environmentally friendly material is obtained that has high rates water resistance and strength. Under the influence of sunlight, thin cellulose fibers are soldered, guaranteeing excellent waterproofing.

Basic material characteristics

The standard sheet is produced in the size 200-95 cm, thickness 3 mm. Wave height (corrugation) 36 mm. Taking into account the fact that when laying the sheets are overlapped, effective area roofing material is 1.6 m. To select the material and calculate correctly the right amount are needed specifications ondulin - roof covering having a stable shape, the calculation of the required volume will not be difficult.

When thinking about what to choose: ondulin or slate, it is worth considering the mass. Ondulin sheet weighs 6 kg, slate - 26 kg, light weight facilitates installation, transportation and supply of sheets to the roof.

Advice! Lightweight roofing sheet allows you to do without additional miscalculations load-bearing structures required for the arrangement of the roof. The material can be laid on the roof of old buildings without fear that the structure will collapse under the weight of the roof carpet.

So, ondulin specifications:

• Ignition 230-300 °, fire safety class KM5 (the latest), because of this, the material is not recommended for use in crowded places, medical, educational institutions.
• Load breaking material 0.96 t / 1m2. In this case, first of all, it is not the sheet itself that is destroyed, but the crate and rafter system.
• High chemical resistance. No other material can tolerate alkalis, acids, oil products as ondulin, the characteristic of the material is suitable for roofing in ecologically unfavorable areas.
• The presence of a hygienic certificate confirms high hygienic performance.

Good water resistance and a 15 year warranty round out the material's basic characteristics.

Benefits of ondulin

Considering the pros and cons of ondulin, one should immediately turn to the characteristics of the material - almost all of them talk about positive qualities ah material. The list of benefits can be supplemented with the following properties:

1. Due to the fact that during the installation of the sheet, nails are driven into the highest point of the wave, the sheets never get wet - drops of water roll down without causing damage to the coating.
2. High hygienic, water-repellent properties are confirmed by decades of use of the roofing product.
3. The light weight makes installation quick and easy, while the rafter system can also be made lightweight.
4. Sheets can be easily and quickly cut with an ordinary hacksaw, and if you lubricate the cut with oil, the work will go faster.
5. The sheets are flexible enough that you can give them any shape, which means, cover the roof of the most bizarre design, as shown in the photo.
6. The low price (from $ 5) is another plus, it turns out that the ondulin roofing material is much cheaper than analogues, except for slate, but does not contain harmful asbestos fiber.

Low noise threshold, biological resistance, non-exposure to UV rays complete the list of positive qualities of the material.

Disadvantages of roofing

But ondulin has disadvantages, often forgotten by manufacturers, presenting the product as one of the best roofing coatings. Most of the negative sides are manifested due to not correct installation, but still there are certain disadvantages:

1. Strength. It is not high, but if the installation technology is violated, in particular, less than 20 laid nails are driven into the sheet, then the strength of the element will noticeably decrease. With a normal crate with a pitch of 0.6 m and a slope above 15 °, the sheet can withstand up to 800 kg / m2.

Important! In a period of intense heat, one should not walk on the coating so that the sheets do not bend, in addition, the release of bitumen impregnation odors is not excluded.

1. Fire hazard- another disadvantage that ondulin has the properties of cellulose as organic material do not exclude the possibility of fire.
2. Durability is always questioned, despite the 15-year warranty. It all depends on the correct installation and operating conditions of the facility. In extreme conditions, only the best metal-tile roof can withstand, but every developer is capable of observing the laying technology in order to extend the life of the material.
3. Burnout. Time and rainfall bring about a change color tone sheets. If the sheets faded quickly enough, it means that the ondulin was of poor quality: the sheets are painted over before impregnation with bituminous compounds, in otherwise the shade will quickly fade.
4. Resistance to biological effects depends on the illumination: in the darkened places of the leaf, mosses form after 2-3 years, the surface turns green. But the same thing happens with slate.

In the case of correct installation, the roofing will last a long time, however, knowing what ondulin is the pros and cons of the material, it will be easier to decide on the choice of roofing.

Modern varieties of material

Manufacturers do not offer too much various types ondulina, these include:

1. Smart (Smart) is a bituminous material that has such qualities as:

• smart lock that complements the functions of the hydro-barrier;
• attachment points;
• smaller dimensions: size 195 * 95 cm, thickness 3 mm, weight reduced by 5%;
• number of combs 10.

1. DiY is a material with even smaller parameters: 5 kg with dimensions 0.2 * 0.75 and a thickness of 3 mm. The number of ridges is 8.

Important! Decrease overall dimensions sheet is a big plus, in this case the installation is done with big amount overlaps, which gives the roof covering the required rigidity and resistance to increased loads.

Consignment always standard sizes, which allows you to select color combinations to the taste of the developer. Therefore, knowing what types of products are ondulin, there is always an option to make the roof individual and aesthetically attractive, as shown in the photo.

Ondulin belongs to roofing materials, sometimes it is called euro-slate. Currently it is widely popular in the Russian markets. Like many materials, it has a number of advantages and some disadvantages. Reviews about ondulin people are very contradictory. Consider what disadvantages Ondulin actually has, and where the bad and negative reviews come from. First, let's figure out how to get it, the composition and properties of this common roofing material.

How is ondulin done?

Ondulin is obtained from organic, cellulose fibers, by pressing these fibers at high temperature over 120 degrees. Then corrugation is performed in order to increase the rigidity of the structure. The resulting sheets are then painted and impregnated with bitumen. For example, in the production of classic slate, asbestos is used, in the production of ondulin, asbestos is not used. Thus, this roofing material is safer and cleaner than slate.

Advantages of ondulin

Ondulin manufacturers guarantee 15 years of waterproofing. Abroad, you can see roofs made of ondulin, which are even more than 30 years old and they have a decent condition. In Russia, ondulin is only 15 years old and there are no known cases of loss of its waterproofing properties. Therefore, many buyers highly appreciate the absolute moisture resistance of ondulin. And he really is one of the best coatings roof and water resistant. Such excellent performance Ondulin has a manufacturing process in which processed and compressed cellulose fibers do not crack over time. For example, even in direct sunlight, the sheets in the overlap areas "stick together" even more firmly. It also enhances moisture resistance - the ondulin fastening system. Its sheets are nailed to the crate at the top of the wave, this helps the water droplets roll down and not penetrate under the roof in the places where the self-tapping screw is attached. Therefore, ondulin has a huge advantage, and few negative reviews can be found on this characteristic. Isolated cases may occur if an illiterate installation was made without observing technology.

Disadvantages of ondulin

The disadvantage is the low strength. For example, a snow load can deform the pavement. Therefore, it is recommended to carry out roofing work using ondulin on roofs with solid sheathing or with a large slope. Ondulin sheets have a rough surface, and it does not allow snow to fall off the roof on its own. In winter, sheets of material can become brittle and walking on a roof, for example to clear snow on a roof, install an antenna, or unclog a chimney, can contribute to cracking, especially in severe frost... In the summer, the sheets soften and the sheets are subject to bending. This is the main limitation, when the roof is very hot, it is not recommended to walk on it and it is advisable not to carry out work on the roof.

They also say that ondulin is paper. Of course, as noted earlier, cellulose fibers are included in the composition, but after all, cellulose is durable material... And many paper products cannot even be torn apart. Durable furniture is made from cellulose fiber (MDF). Moreover, ondulin makes the cellulose sheet corrugated, profiled, and this increases the strength characteristics.

Again, proper editing must be done. When installing the roof, you must strictly follow the instructions. Each sheet should be reinforced with 20 nails to help keep the roof strong. If the installation is performed according to the instructions and all installation conditions are met, then the roof will not fly off in strong winds and the snow load is not terrible for it. Do not skimp on nails, especially since they are included with each sheet.

The step of the lathing is large enough - 60 cm with a slope of more than 15 degrees, so the lathing must be correct and this will distribute the load and make it even. If everything is done well, then ondulin can withstand a weight of up to 960 kg for square meter and it is possible to walk on it at the attachment points and perform necessary work on the roof.

Sometimes there may be complaints about the aesthetic characteristics of the roof. For example, loss of color saturation. The roof fades quickly, in 2-3 years and can protrude dark spots... This disadvantage is eliminated by improving the painting technology and increasing its resistance to ultraviolet radiation... Ondulin has a small selection of colors.

Comparison of metal tiles and ondulin

Ondulin can be compared with metal tiles. But here the price comes into play. Metal tiles are more reliable, but much more expensive. If we compare ondulin with a metal that has the same price, then the metal is much inferior to ondulin. Metal, almost foil, and it will not withstand any load and will rust. The thickness of the metal is 0.35-0.45mm, and the ondulin is 3mm and it is much stronger.

Dignity can be found in low strength. This material is easy to cut and can be shaped into any shape. It is easy to repair and any damaged area can be quickly replaced.

The disadvantages of ondulin include flammability. If a fire starts from the roof, then ondulin will ignite faster than metal. Although most often the fire starts inside the house, and not from the roof. Therefore, such a characteristic as the flammability of the roof does not acquire very great importance... It has even been noticed that the victims of fires die not from fire, but from poisoning. carbon monoxide... And if the ondulin burns out quickly, then there will be a release of smoke to the outside and there will be a lower concentration of smoke in the room.

Before choosing a roofing material, decide whether you want to save on installation, which is of course undesirable and on which structure the roof, house or garage is installed, and many other factors. If ondulin will be exposed to increased risks, then select materials according to the operating conditions.

If ondulin has shortcomings, of course, like any roofing material. No materials, no flaws. If they tell you that they are not there, do not believe it. I would like to dwell on the price once again, ondulin inexpensive material... When you buy economical material, you have to assume that you are solving only a roofing issue and not for centuries. With a competent and high-quality installation and without huge critical loads, you will definitely be satisfied with ondulin.

Today, almost no one covers the roof with gray shabby slate, which is prone to break even at the installation stage. Owners of private houses are increasingly preferring an outwardly attractive, durable ondulin. He, being pressed cellulose impregnated with bitumen thermosin, is an excellent substitute for carcinogenic asbestos-cement sheets... For this reason, it is called differently - euro slate.

Material features

The stage of heating and squeezing the cellulose provides the highest strength. On the roof, these thin fibers, in contact with the rays of the sun, are better soldered together, which adds resistance to various negative factors.

After the leaf takes on a wavy shape, it is painted in the appropriate color: green, brown, black or burgundy. According to the reviews of the owners on the forums, it can be understood that some owners are unhappy with such a narrow assortment in terms of shade. These colors can be produced in glossy (with the addition of silicone) and matt (based on acrylic paint) variants, look different not only visually, but also to the touch: the first type is perfectly smooth, the second has a rough surface. Ondulin can be bought with a camouflage pattern or a combination of colors.

The painted sheets are then impregnated with bitumen saturated with polymer additives. Euroslate turns out to be incredibly resistant to moisture, alkalis, acids, UV radiation. It cannot be spoiled by either industrial gases, or products made from oil (take, for example, gasoline), or frost, or gusty winds, or a high snow load (of course, provided that the crate system is properly arranged). And the mineral fillers included in the composition help prevent the formation of fungi and mold.

Ondulin is 100% organic, which means it is environmentally friendly and safe. Manufacturers guarantee that such building material will last at least 15-20 years, although in fact its operation may well be half a century.

Compared to other coatings (for example, metal tiles, slate) it has the best sound insulating properties... Due to this quality, the roof does not need to be equipped with an additional noise-absorbing layer, in heavy rain and hail it will always be quiet and comfortable inside the house.

Sheet parameters vary depending on the country of manufacture. In Russia, the most common material is made by the French company of the same name ONDULINE. Such canvases are characterized by dimensions: 2 m in length, 0.95 m in width, which leads to a total area of ​​1.9 and a useful 1.6 m2. The thickness is 3 mm, the weight is 6 kg, the euro-slate does not in any way make the structure heavier. The height of the corrugation in the French variation is the largest - 36 mm. (for comparison: models from Belgium and the USA have 32 and 35 mm, respectively).

Homeowners & Roofers Reviews

“I have been living with Euroslate for over 8 years. Everything suits: colors, durability, sound insulation, water resistance. And the costs of the work were not so huge (I compare it with a neighbor's house, where metal tiles were used as a covering). In general, I did not find any shortcomings of ondulin and I hope that the roof will please and protect for a long time to come. "

Alexey, Yekaterinburg.

“Although I am not versed in construction, and my husband chose the material for the roof, I want to say that ondulin is best suited for the roof of residential buildings. Why? Unlike plain slate, it is outwardly aesthetic and environmentally friendly. During a rainstorm, large hail, the noise is perfectly inaudible in the rooms, even in the attic. Although, according to reviews, it still has a lot of advantages, but I did not find any shortcomings. "

Marina, Minsk.

“In the summer, my brother and I covered the terrace of my grandmother's house. Since the general background was cherry, the ondulin was taken in the appropriate color (burgundy). In order to understand how to conduct installation work, watched several videos from YouTube. However, when buying, the seller gave us instructions, where everything was described in detail and clearly (with pictures). So to acquire it means that nothing needs to be improvised. Anyone who knows how to handle a hammer and a hacksaw can handle the installation. ”

Pavel, Nizhny Novgorod.

Vladimir, St. Petersburg.

“As a novice builder, I still deal with easy-to-install, flexible products. For the roof, ondulin is considered as such. Since it belongs to the fire hazard group (this is the main drawback), it is better to take it covered with non-combustible paint with all certificates and a hygienic conclusion. In order to protect the coating from damage under load, I also recommend making a crate with a small step or even laying it on a solid base. After installation, the joints and overlaps should be treated with a bitumen sealant - this will protect against leaking and getting wet. "

Egor, Moscow.

Compare the advantages and disadvantages of ondulin

The opinions of the owners and builders are mostly good, this is due to the advantageous aspects of the material, that is:

1. harmlessness to residents and external environment in general, since ondulin is environmentally friendly;

2. plasticity, which allows you to work with any surfaces with a significant radius of curvature;

3. excellent sound insulating properties;

4. simplicity in processing, the ability to rationally cut the material, to reduce its costs;

5. low weight, which is good both for the structure (it is not heavier) and for the roofer (installation is easier, in a single installation);

6.strength (guaranteed not to deform under snow load and when there are 1-2 people on it);

7. invariability of the structure both during freezing down to -50 ° C and heating + 110;

8.reliability - with proper fixation, they are not afraid of either strong winds(with gusts up to 170 km / h), nor aggressive substances (salts, alkalis, acids) found in the environment;

9.High resistance to corrosion, moisture, the development of fungi, mold and other plaque;

10. presentable appearance and the ability, with certain installation actions, to get a look under the tiles;

11. laying, both for covering new roofs and old ones (on top of the old material);

12. budgetary price.

Of the shortcomings, some homeowners single out a not too rich assortment of colors. However, those colors that manufacturers represent are universal and quite popular to meet aesthetic needs and implementation. architectural solutions... There is only one drawback - flammability. But this problem can be solved by taking measures to increase the fire resistance of the structure.

When is it advisable to use ondulin?

Since the composition includes bituminous components, it belongs to the last class of combustibility KM5, that is, it is highly flammable. For the roof of private houses, the euro slate is ideal, even if the truss system has a lightweight version. Elastic, it can be used for roofs with complex configurations. Good soundproofing qualities additionally confirm the use of the material in favor of residential buildings.

If the area is quite voluminous, it is better to replace it with another coating (for example, corrugated board), which can be made to order of the required length. Of course, you can leave the euro slate for work, but then, due to its size, the installation will take much longer.

Outbuildings in the form of sheds, gazebos, pens for animals, country houses it is also appropriate to cover with ondulin. Due to the lightness of the sheets and their relatively small dimensions, the installation can be carried out independently, and without disassembling the old roof.

Price

How much the ondulin roof will cost is a question that does not imply a definite answer. It all depends primarily on the price per sheet.

The parameters of the sheets are the same (standard), and the prices differ depending on the color scheme:
