Ondulin pros, cons and characteristics of roofing. Ondulin: arguments "for" and "against" a well-known brand What is ondulin produced from and how

In 1944, the production of ondulin, a popular roofing building material, started at the Paris enterprise. Six enterprises produce this unique building material.

What is ondulin, composition

What is ondulin made of? For the production of ondulin, refined bitumen, cellulose fibers, fiberglass, mineral additives (as a filler), resins (for strength and impregnation) are used. The fibers are enriched with bitumen at high pressure and temperature. The ondulin sheet retains a rich color for a long time, it is well protected due to mineral pigments that are added during manufacture. These pigments allow you to get ondulin of various shades. Such roofing material is produced exclusively from environmental materials. Therefore, it is not without reason that ondulin is considered to be the most high-quality roofing system. By the way, ondulin is also used for cladding.

Ondulin sheet dimensions

length 2 m;
width 95 cm;
thickness 3 mm;

Roofing with ondulin is excellent in the highest quality, quite affordable cost. Such a roof will withstand strong temperature fluctuations, therefore it can be mounted in a variety of climatic zones. Ondulin is uncomplicated in production. Appropriate equipment will be required, cellulose fiber, which, after processing, which includes a press, is enriched with bitumen at significant pressures and temperature conditions. Ondulin, after the necessary manipulations, acquires exactly the qualities that are valued in it: resistance to water, shock, high / low temperatures. Ondulin, in addition to the strength indicator, is also considered a relatively light building material.

Advantages of ondulin, a popular roofing material

This roofing material has high thermal insulation, good sound insulation. Therefore, the house will be quiet even when it rains. Ondulin does not exfoliate, does not change color due to a negative environment. It does not need to be constantly tinted.

What is ondulin? This is a reliable roof that does not rust, does not rot, and is resistant to corrosion. It can be noted that ondulin is protected from processes that could destroy it. The properties of ondulin are preserved for many years. Ondulin meets all fire regulations, since it is not combustible. Such a roof does not harm health at all and is safe for residents.

Ondulin is characterized by less pressure on the roof structure than other roofing building materials. In addition, ondulin is used when it is necessary to repair the roof of a dilapidated building that cannot withstand significant loads. Also, the material stands out for its flexibility, because it is used in arches, and in other structures where this property is required.

Video story about ondulin

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

In fact, the term "ondulin" refers to 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 where they are used.

Ondulin is a modern, technologically advanced roofing material that creates a stable, moisture-resistant coating. It is a product and trademark of the French company Onduline, which started its production over 70 years ago.

This roofing covering, which is made on the basis of cellulose impregnated with refined 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 a classic ondulin is carried out in the same way as laying a traditional slate. The wave height of this material is 36 mm and the thickness of the sheet is 3 mm. The cost of 1 m2 of such a roof will be 300-350 rubles.

The product of the collaboration of the French company "Onduline" and Italian designers. This roofing material is a symbiosis. Onduvilla is a cut strip 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, its waves imitate ceramic tiles in the Mediterranean style. Such a coating with an area of 1 m2 weighs only 4 kg. Onduvilla costs from 410 rubles per 1 square meter.

Onduvilla - a mixture of tiles and ondulina.

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

Ondulin coating tends to burn out under the action of ultraviolet rays, and the destruction of the pigment occurs unevenly. To update the color of the roof, a primer is applied to it, and then painted.

Interesting! Initially, ondulin roofing material was developed as a tool for repairing metal or tile roofs, which does not require the dismantling of the structure. Lightness and excellent moisture-proof 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.

Production 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 their environmentally friendly, safe for health components, which cannot be said about.

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

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, obtaining a wet paper pulp, which is called pulp.
The next phase of production is called drying. During it, the prepared pulp is fed to the conveyor, where it is given a wavy shape, and then dried.
Completely dried sheets are cut according to the standard dimensions of the material, after which they are sent to the impregnation shop.
Sheets of roofing material are impregnated with oil bitumen on both sides under the influence of high temperature and pressure.
Onduvilla are stacked on pallets and then wrapped with shrink film to prevent mechanical and weather effects on the material during transportation or storage.

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

Characteristics

Ondulin is used for roof repair, new flooring, as a lining for ceramic tiles, or for creating fences and water-repellent screens. The coating of this material has a guaranteed service life of 15 years, however, according to the reviews of professional roofers, it reliably serves 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, while not the sheet itself is destroyed, but the crate or truss frame.
The modulus of elasticity of the material is 3.940-8.160 kgf/m2, due to which the sheet has high flexibility.
The material can withstand temperatures up to 110 degrees without deforming, without losing elasticity, rigidity.
The noise reduction level of ondulin is 40 dB, which allows you to accept this material without additional sound insulation.
The thermal conductivity coefficient of ondulin is 0.19 kcal/mchos. The thermal conductivity of this material is much lower than that of, so that the roof does not heat up so much under the influence of the sun.
This roofing material, without loss of mechanical strength, moisture resistance, withstands at least 25 cycles of freezing and thawing, which explains the long service life of roofs coated with ondulin.

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

Ondulin is a well-known roofing material that came to us from Europe. Its homeland is France, from where it was distributed and reached us. Due to the 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 watching the photo and video of ondulin, you can get acquainted with its appearance in detail.

Compound

This material is an environmentally friendly product. It is harmless to both humans and the environment, since it is made 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, refined products);
resistance to mechanical loads - per 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:

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

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

The first thing that interests any buyer when choosing a roofing material is its durability. Because no one will cover the roof every year, manufacturers give a guarantee of 15 years, but it has actually 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 step is needed 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 that are the same color as ondulin. After installation, this building material holds very tightly and calmly endures strong winds.

Advantages

The weight of the ondulin sheet is not large, so transportation and installation will not cause any special problems. Due to its lightness, often, it is 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 palettes makes it easy to choose the desired color. Coloring materials impregnate ondulin during the production of sheets, therefore, under the influence of sunlight, the paint will not fade quickly. But, even if this happens, the ondulin roof can be repainted.

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 the natural environment, such temperatures do not exist, so you should not pay close attention to this fact. The only warning may apply to buildings that have increased fire safety requirements (kindergarten, school, etc.).

Flaws

Ondulin has practically no drawbacks, but, nevertheless, some features should be clarified. With prolonged exposure to the sun, the color fades, but this is fixable with ordinary painting. The presence of an 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 of people who used it. According to numerous positive reviews, it becomes clear that this roofing material has an undeniable advantage over other similar materials. Yes, in some respects it is inferior to others, but if taken as a whole: cost, durability, complexity of installation and other characteristics, everyone agrees that ondulin is the best option for a roof.

Ondulin

Ondulin- roofing material belonging to the category of bituminous sheets is a light, rough, wavy material made from organic fibers (cardboard + additives) at high temperature and pressure. Then they are painted with special paint and impregnated with bitumen. It is produced in various colors in different countries of the world, including Russia.

Advantages

low noise level during precipitation
easy installation, the ability to install alone
ease of transportation and storage due to the low weight of one sheet of material

Flaws

flammability
in summer and winter, repair work is difficult due to the high plasticity or fragility of bitumen, which is part of ondulin
the need for a dense crate to prevent deformation of ondulin sheets

For external resemblance to asbestos-cement slate, ondulin for roofing is often called bitumen euroslate. However, these materials differ significantly in performance, color palette and composition. Sheets of this material are more competitors of metal tiles. It is their owners of private houses that are most often compared when choosing building materials for roofing. They are more similar in color and price.

What is ondulin?

Ondulin was created in France (Europe) at the ONDUliNE company. It is customary to refer to environmentally friendly organic building materials. This cheap roofing is based on ordinary cellulose. But so that it does not get wet under precipitation on the roof, the canvas pressed from it is treated with bituminous impregnation.

The composition for laying the roof includes:

Cellulose (paper).

mineral filler.

Bitumen with polymer resins.

Pigments.

In production, cellulose is pressed into plates with a thickness of 2-3 mm and corrugated to give the waves the desired size. Then it is impregnated with a mixture of bitumen with pigmenting additives. The output is a wavy sheet that looks like slate or a metal tile with a profile in the form of a wave.

Sectional view

Specifications are as follows:

Table of physical and mechanical characteristics

The considered roofing material is resistant to alkalis, oil products and acids. It calmly withstands a column of snow of 2.5-3 meters and heavy showers. Manufacturers claim a warranty period of 15 years, but in fact, ondulin can last up to half a century after being laid on the roof of a cottage or household building. It has excellent water resistance, but frankly poor performance in terms of fire resistance (it is included in the last highly combustible group of building materials).

Be careful - the material is not fire resistant

When burning, ondulin emits toxic substances and strong smoke. But it can catch fire on roofs from sparks or flying coals only where the flame is able to reach the cellulose - in damaged areas or from the end of the sheet. The surface of the latter is impregnated with flame retardants. It will flare up only if it turns out to be hot up to 200–230 C.

Sheet dimensions

All sheets produced in Russia by the ONDUliNE concern have typical standard dimensions of 2000 x 960 mm or 2000 x 760 mm. Their thickness is 3 mm, the wave height is 36, and the number of waves is 10 or 8. Other sizes of ondulin roofing coatings for roofs are not manufactured at domestic factories. However, in the US and Europe, individual manufacturers make them 1–1.22 meters wide.

Sheet dimensions

Standardized sheet dimensions simplify the calculation of the roof, its installation and the purchase of material. The laying of flexible slabs with a square of less than two square meters can be handled by one person. Sail and weight are minimal. Waves in all cases also have the same size. The best roofing building material for the roof in terms of lightness and ease of installation cannot be found.

Advantages and disadvantages

Ondulin for the roof has a lot of advantages, among which are:

To cut ondulin sheets, it is enough to have a hacksaw in your hands for wood. For the price - slate is 30-40% cheaper than its bitumen counterpart, but contains harmful asbestos. At the same time, it is comparable in cost to a sheet with a metal roof tile, but it is easier to install.

Among the disadvantages of ondulin roofing it is worth noting:

Often, the owners of cottages mention as a minus that the paper-bitumen ondulin is too soft. Roofs with it are supposedly not able to withstand snow and even a person, and it is better to choose a more expensive and durable metal profiled sheet. But here the question is more about the correct execution of the crate. Its step under the roof should be less than 0.6 meters, otherwise the coating will definitely bend. Whereas it can be laid on a crate with a large distance between the slats.

Do the trim correctly

Which is better: ondulin or metal tile?

Compare 2 materials

When choosing “ondulin or metal tile”, it is necessary to focus on the possibilities of the wallet, in what conditions the roof will be used and the shape of the latter. At a price per square, such a roof, taking into account installation costs, is comparable to a metal tile.

The material itself is cheaper than metal tiles. However, the shape of the waves and the size of the sheet are such that there are fewer trimmings as a result of cutting. Plus, self-tapping screws per square meter of ondulin coating will require much more than for corrugated board.

As a result, the cost of the roof in both cases is approximately the same.

In terms of service life, the profiled sheet wins - 30–50 years versus 10–15 years. But much depends on the quality of the protective coating of the metal tile. The more durable it is, the more expensive the profiled sheet will cost. The situation is similar with fire resistance. A thin profiled sheet, comparable in price to ondulin, burns out as quickly from exposure to open fire as a bitumen-paper coating. A thicker one is a good option and costs more.

More significantly, the metal tile differs from the ondulin competitor in terms of strength. The roof from the first tolerates frost, heat and precipitation better. But it is easier to cut it, it can cover any complex curved roof. A metal profiled sheet is not always possible to bend at the desired angle.

The use of ondulin

It is enough to look at the photo of the types of roofs of houses that are covered with ondulin to understand that you cannot find a more universal material for roofing. They can close any bends and corners. And you don’t have to throw away numerous trimmings resulting from the need to superimpose exactly wave upon wave. However, if the roof is shed without exotic peaks and turrets, then it is better to prefer metal tiles or less expensive slate.

It costs about 400-500 rubles / m2. Sheets are marked for special roofing fasteners, which are included with each package of this material. Everything is calculated in advance, the consumption of nails for this roof is 20 pieces / sheet. She does not require special care. The rain will wash everything. Subject to technology, ondulin will last 30-40 years. But if the installation is done unprofessionally, then it will have to be changed after 3-4 years.
