All about ondulin. Ondulin: arguments for and against a well-known brand

Reading time ≈ 4 minutes

Ondulin is a well-known roofing material that came to us from Europe. Its homeland is France, from where it was spread and reached us. Due to its low cost, in comparison with other analogues, ease of installation, it quickly gained popularity and is still in demand today. For a certain similarity with ordinary slate, it is also called bituminous slate. After looking at the photos and videos of ondulin, you can get acquainted with its appearance in detail.

Composition

This material is an environmentally friendly product. It is harmless to both humans and the environment, since it is produced only from natural ingredients. It includes:

• cellulose;
• resin;
• bitumen;
• mineral fillers;
• pigments.

Technical characteristics of ondulin

The ability to operate Ondulin for a long time is facilitated by its technical characteristics:

• the ability to withstand contact with chemical components (alkalis, acids, petroleum products);
• resistance to mechanical loads - for 1 m² up to 960 kg;
• excellent water resistance.

Ondulin sheet weighs 6.5 kg, sheets of this roofing material have the following standard dimensions:

• in length - 2,000 mm;
• width - 960 mm;
• in thickness - 3 mm;
• wave height - 36 mm.

Among the parameters that negatively affect the operational capabilities of the material, one can note the fire safety class - KM5. The material can catch fire at temperatures above 230 ° C, because of this Ondulin cannot be used in medical institutions. However, do not be afraid that the roof will start to burn from the falling of flammable objects on it. Ondulin can catch fire only from the cut side, the surface of the sheets does not catch fire.

The first thing that interests any buyer when choosing a material for a roof is its durability. Because no one will cover the roof every year, the manufacturers give a 15-year warranty, but, in fact, it has been proven that thanks to the technical characteristics of ondulin, it can last up to 50 years.

It becomes brittle at very low temperatures, and softens at too high temperatures. However, these properties of ondulin are not a big drawback, since they are easily leveled. A crate with a more frequent pitch is required and the strength of the sheets will be guaranteed. It is fastened like a regular slate with roofing nails. For an aesthetic appearance, nails are purchased with hats of the same color as ondulin. After installation, this building material holds very tightly and tolerates strong winds calmly.

Benefits

The weight of the ondulin sheet is not large, so transportation and installation will not cause any special problems. Due to its lightness, it is often laid directly on top of the old coating. Also, this material is very flexible, which is another advantage of ondulin.

A large selection of color palette allows you to easily choose the desired color. Coloring materials impregnate ondulin in the process of making sheets, therefore, under the influence of sunlight, the paint will not quickly fade. But, even if this happened, the ondulin roof can be painted again.

In terms of fire resistance, this roofing material is not in the first place. However, this does not mean that it is highly flammable. Its ignition temperature ranges from 230 to 300 degrees. In a natural environment, such temperatures do not exist, so this fact should not be paid close attention. The only warning may apply to buildings that have increased requirements for fire safety (kindergarten, school, etc.).

disadvantages

Ondulin has practically no drawbacks, but, nevertheless, some features should be clarified. With prolonged exposure to the sun, the color fades, but this can be corrected by ordinary painting. Unpleasant smell of bitumen during extreme heat. There are roofing materials whose durability is much greater than that of ondulin, however, the price of such a roof will be much more expensive.

You can list and compare endlessly, but there is a main indicator of quality - reviews about ondulin from people who used it. According to numerous positive reviews, it becomes clear that this roofing material has an indisputable advantage over other, similar materials. Yes, in some respects it is inferior to others, but if we take it as a whole: cost, durability, installation complexity and other characteristics, everyone agrees that ondulin is the best option for roofing.

Many people, far from construction, wonder what ondulin is. Since this new word is constantly heard, it attracts a lot of attention from both specialists interested in modern technology and curious homeowners.

In fact, the term "ondulin" means a modern type of roofing material based on cellulose and bitumen, the coating of which reliably protects the roof from precipitation and adverse weather events for many years. In this article we will tell you what ondulin is made of, how much it costs, what types of this material are produced, and also where they are used.

Ondulin is a modern technologically advanced roofing material, with the help of which a stable, moisture-resistant coating is created. It is a product and a protected trademark of the French company Onduline, which began production over 70 years ago.

This roof covering, which is made on the basis of cellulose impregnated with purified bitumen, entered the Russian market only 10-15 years ago, after which it earned the trust of professional roofers and developers. Currently, the following types of this material are distinguished:

• Ondulin

The classic ondulin coating is a rectangular sheet with a wavy profile, the size of which is 200x950 cm. It has high moisture-proof properties, light weight and a guaranteed service life of 15 years.

Installation of classic ondulin is performed in the same way as laying traditional slate. The wave height of this material is 36 mm and the sheet thickness is 3 mm. The cost of 1 m2 of such a roof will be 300-350 rubles.

A collaboration product of the French company Onduline and Italian designers. This roofing material is symbiotic. Onduvilla is cut strips of corrugation, the wave height of which is 36 mm, 40 cm wide, 104-106 cm long.

Onduvilla is laid in tiers with a slight overlap, and its waves imitate Mediterranean-style ceramic tiles. Such a covering with an area of \u200b\u200b1 m2 weighs only 4 kg. Onduvilla costs from 410 rubles per 1 square meter.

Onduvilla is a mixture of tiles and ondulin.

By adding natural pigments, the material is dyed in the required colors. Standard colors include black, brown, green and red.

Onduline coating tends to fade under the influence of ultraviolet rays, and the destruction of the pigment is uneven. To renew the color of the roof, a primer is applied to it, and then painted.

Interesting! Initially, ondulin roofing material was developed as a means for repairing a roof made of metal or tiles, which does not require dismantling the structure. The lightness and excellent moisture protection properties made it possible to lay this material on top of an old roofing cake. During operation, it began to be used to cover roofs on its own.

Manufacturing process

Light weight, moisture-proof properties and simplicity are explained by the characteristics of the substances of which it is composed. He, like onduvilla, is produced from environmentally friendly, safe components for health, which cannot be said about.

The composition includes waste from the cellulose industry, petroleum bitumen, polymer resins, natural pigments, modifiers. In the production process, onduline coating and onduvilla go through 5 stages in sequence:

1. The first stage in the manufacture of this roofing material is called wet, since during it waste paper, cleaned of impurities or debris, is mixed with water, resulting in a wet paper pulp called pulp.
2. The next production phase is called drying. During it, the prepared pulp is fed to a conveyor, where it is given a wavy shape and then dried.
3. Completely dried sheets are cut according to standard material dimensions and then sent to the impregnation workshop.
4. Roofing sheets are impregnated with petroleum bitumen on both sides under high temperature and pressure.
5. Onduvilla are stacked on pallets and then wrapped with shrink wrap to prevent mechanical and weather effects on the material during transport or storage.

The conveyor for the production of this roofing material releases one finished sheet in 4 seconds. Ondulin is produced from the moment the pulp is fed to the conveyor to packaging within 45 minutes. During the manufacturing process, all components that make up the coating are checked for compliance with safety requirements. Due to strict quality control, it is considered one of the most environmentally friendly materials.

Specifications

Ondulin is used for roof repairs, new flooring, as a lining for ceramic tiles or for creating fences and water-repellent screens. The coating made of this material has a guaranteed service life of 15 years, however, according to the reviews of professional roofers, it will reliably serve at least 30-50 years.

Light weight, affordable cost, moisture-repellent properties and resistance to biological factors of destruction make ondulin indispensable in private housing construction. The technical characteristics of this material meet high standards:

• The breaking load of roofs covered with ondulin is at least 960 kgf / m2, and not the sheet itself is destroyed, but the crate or rafter frame.
• The elastic modulus of the material is 3.940-8.160 kgf / m2, which makes the sheet highly flexible.
• The material can withstand temperatures up to 110 degrees, without deforming, without losing its elasticity, rigidity.
• The noise reduction level of ondulin is 40 dB, which allows you to accept this material without additional noise insulation.
• The thermal conductivity coefficient of ondulin is 0.19 kcal / mchoC. The thermal conductivity of this material is much lower than that of that, due to which the roof does not heat up so much under the influence of the sun.
• This roofing material withstands at least 25 freeze and thaw cycles without loss of mechanical strength and moisture resistance, which explains the long service life of roofs with ondulin coating.

Note! Ondulin and onduvilla are flammable roofing materials, since the components that make up the composition do not have fire protection. To increase fire safety, manufacturers do not recommend using such a coating for roofs through which chimneys of solid fuel stoves or fireplaces are led out. To prevent a fire, it is necessary to equip the pipe passage with a fire-resistant box, as well as install a sheet metal spark arrestor.

Most people, even not versed in anything in construction, have a general idea of \u200b\u200bondulin: for some it is a building material, for others it is a roof covering. However, even experts sometimes cannot boast of knowledge about its characteristics and unique properties. So, why is this material attractive to developers?

Brief characteristics of ondulin

Ondulin is a modern material used for roofing, which combines properties such as lightness and strength at the same time. With a production guarantee of 15 years, it has been in excellent operation for about 50 years. Ondulin sheets are made without the addition of asbestos, which is part of ordinary slate and has a negative impact on human health.

In addition, developers who have no idea what ondulin are made of are amazed at its ability to withstand any climatic conditions, for example, when used in regions where there is extreme heat or, conversely, severe frosts.

The correctness of the lathing is of great importance, since such a structure gives the roofing additional properties - it copes well with the snow load, as well as with a hurricane wind speed of 53 m / s. All of the above data are confirmed by American and British scientists.

The advantages of installing an ondulin roof

Among the indisputable advantages of the material are:

• The ability of low water absorption, due to which the necessary microclimate is always maintained in the under-roof space, and the sheets, if the temperature drops to 0 degrees, remain the same.
• Good resistance to weather changes in the form of rain, snow, wind and other climatic influences.
• Prevents the formation of fungi and bacteria.
• The presence of protective properties against the effects of acids, alkalis, industrial gases and other chemical reactions.
• Use in the production of harmless components. The composition of ondulin includes environmentally friendly raw materials, so the output is safe for the surrounding creatures.

With long-term use (7-10 years), the coating may lose its brightness and attractiveness, then it is enough to paint it in the desired color. However, before applying acrylic, vinyl or epoxy vinyl paint, surface preparation is carried out - priming the coating.

Any analog of ondulin can also be used to install the roof, for example, transparent ondulin, which is also called. Installation and repair of ondulin, as well as its analogous materials, in general, is carried out in the same way as work with slate, the difference is possible only in the characteristics of the starting materials and their composition.

Features of the composition of ondulin, technology of its production

For many developers, the question of ondulin is important, what is it made of, and what properties other components have. In the production of roofing material, waste paper, bitumen and a large amount of mineral components are used. At the preliminary stage, all of the above is thoroughly checked for compliance with quality requirements.

During the first "wet" stage, the waste paper is cleaned of debris and converted into paper pulp, which will become the basis of the future coating. The second stage consists in processing the resulting pulp - it is lowered onto a conveyor, where, under the action of machines, it is given a wavy shape and thoroughly dried.

Dry blanks are cut into sheets of the required length and in a special workshop they are impregnated with the composition of bitumen and formed into pallets, which are taken into account.

After staining, the material is again impregnated with a layer of bitumen - the presence of this stage makes the ondulin manufacturing technology unique, unlike the manufacture of its analogues. The top layer of bitumen protects against paint fading.

At the final stage, ondulin sheets are packed, ondulin films are wound on top of them to prevent mechanical damage during transportation.

In 4 seconds, the conveyor processes 1 sheet, and the material passes all stages in about 45 minutes.

The main components that make up ondulin

With a detailed examination of the components that make up ondulin, the following list can be presented:

• processed cellulose fiber;
• deeply purified bitumen;
• mineral filler;
• resin.

As for the technical parameters, then:

• length of ondulin 2 m;
• sheet width 0.95 m;
• total thickness of about 3 mm;
• wave height - 36 mm.

Due to its low weight (only 6.5 kg), this roof covering is easy to transport and install.

The special physical and mechanical properties in general create a high-quality material that has no analogues on the market:

• The destruction rate of the onduline roof is 960 kgf / sq. m., moreover, that it is not the sheet itself that is destroyed, but its base ().
• With maximum thermal resistance, the material fully retains its qualities and shape.
• When the ambient temperature changes, only a slight change in the thermal conductivity of the coating is observed, for example, when the thermometer mark jumps from 35 degrees to 40 degrees and, then, by 50 degrees, it will be 0.19 Kcal / mchoC, 0.20 Kcal / mchoC and 0.195 Kcal / mchoC, respectively.
• Sound insulation is 40 dB.
• The appearance and structure of the material does not change even after 25 freeze and thaw cycles.

Where Ondulin can be used

Ondulin is used in the installation of the roof of private houses and cottages. Lightweight material can be laid directly on top of old flooring. Since the load is minimal, you do not have to worry about additional strengthening of the rafter system. This technology allows you to perform work without opening the roof, thereby protecting the interior from the weather.

Attractiveness of appearance, ease of installation, flexibility of the material - this is just a small list of the advantages of this roofing covering, in addition to which painting of ondulin in any color can be added. All this makes it possible to use the material not only in the construction of residential buildings, but also in trade facilities, cafes, entertainment clubs and other buildings of a similar purpose. Note that all commercial prefabricated structures can be lightweight ondulin roofing.

The high level of plasticity of cover sheets has been successfully used in construction. Any curved plane with a radius of curvature of more than 5 m can be covered with this material.

For those who, when laying the roof, give preference to shingles, we offer ondulin soft shingles, obtained using a special technology of mounting the material, which looks quite similar to a tile covering.

The environmental friendliness and quality of the components that make up ondulin, the possibility of using it in various areas of construction - all this serves as a kind of guarantee of the reliability of the presented material. Ondulin is unique to most developers with experience with different roofing (read: "").

The first sales of Ondulin roofing material fell on the beginning of 2000. Now is the time to evaluate how much the service life declared by the manufacturer is true.

Roofing sheets, which are known to everyone as "Euroslate", have become widely used in Russia in the last decade. But under this name, buyers combine products from different manufacturers. In particular, Korrubit is produced by the Turkish company VTM.

Euroslate Ondura has been successfully used on rooftops all over the world for over 40 years. Ondura corrugated sheets have quite a few advantages over other roofing materials.

The Belgian company ATAB is a subsidiary of the IKO concern and has been producing building waterproofing materials for more than a century. Among other positions at ASBO factories, ATAB produces Aqualine corrugated roofing material.

The question, in fact, is not an idle one, since at first glance it is difficult to understand what is the difference between Euroslate of different brands, which are presented on the modern market of roofing materials.

Material flaws identified by homeowners

The house covered by Ondulin

When people talk about any material, they always start with its merits, and we will start with its disadvantages. And first of all, with consumer properties, which can be noticed even by a person who is not associated with construction.

We conclude this section with the opinion of roofers' experts, who believe that the cost of the material is not only the price per sheet, but takes into account all the total costs, including the crate, installation, and the service life of the roofing. If you make a full recount, then the same roof, covered with Ondulin and a metal seam with Pural coating, will cost a quarter more expensive than a seam roof.
Since the shortcomings of the material are always a continuation of its merits, in the next sections we will see what exactly these advantages are determined by.

Some technical data about the production process

All properties of the material are determined by the method of its manufacture. If you understand in detail, then ondulin - what is it? The basis is cellulose or cardboard, as it is contemptuously called on construction forums. During the production process, the cellulose base is impregnated with a complex composition of bitumen, resin and mineral additives.

The production process technology is briefly as follows:

• Waste paper is cleaned of debris, crushed and poured with a special solution so that the mixture becomes homogeneous.
• The mixture or pulp undergoes a molding process, when a wavy web is formed from it by pressing, and then drying.
• After drying, the canvas is painted with mineral dyes and then impregnated with bitumen under pressure.
• Next, the canvases are cut into sheets and sent for the next drying, after which the sheets are ready for work.

You can watch a report on the production process in the video:

Russian-made Ondulin has been produced since July 2008 at a factory in Nizhny Novgorod. The cost of Ondulin per square meter is significantly higher than the cost of asbestos-cement slate, slightly lower than metal tiles and significantly lower than bituminous tiles.

How much Ondulin costs in retail prices depends on the cost of oil as a raw material for bitumen production, transportation and storage costs of the manufacturer, and the market situation in the region of sale.

But, regardless of the price of the material, there is one subtlety that has been noticed by those who have been dealing with roofs for a long time: earlier the manufacturer declared a useful life of 30 years, and now it is half that. Considerations were expressed that this is due to the lower quality of domestic material, as well as the fact that buildings covered with ondulin in Europe do not stand for 30 years, but in our country it is easy. And in order to protect itself from claims, the manufacturer has reduced the warranty period. But representatives of the Russian factory argue that Ondulin's production is the same at all the company's enterprises: in Russia, and in France, and in Poland. As regards the 15-year warranty period, the manufacturer's clarifications were as follows: 15 years is a guarantee of the waterproofing of the material, and the service life of Ondulin is up to 50 years. It is difficult to say how to respond to such answers, since a roof that has lost its water resistance is considered to have lost its technical characteristics. Those who wish to clarify this statement are sent for a response to the manufacturer.

But, what, of course, makes sense to agree with the representatives of the factory, is that installation errors significantly reduce the useful life of the material. The most common of them are given in the next section.

Common installation errors
