Corrugated sheeting or ondulin – which is better to choose? How is ondulin different from corrugated sheeting? Ondulin pros and cons.

Ondulin (also called Euroslate) is a beautiful modern multi-colored roof covering organic origin. Ondulin, of course, has pros and cons, and they are actively discussed by both builders and homeowners. But still, the ondulin roof looks very attractive. But it’s worth talking about its quality, advantages and disadvantages.

Ondulin is a fairly cheap material for roofs, which is why it is very popular in the construction market.

Ondulin: properties and technical characteristics

This material was invented by the French. During its production, cellulose fibers are heated to a temperature of at least 120 degrees and pressed, crimping. The finished sheets are painted in different colors and impregnated with bitumen, adding polymers.

The result is a safe and environmentally friendly product that is superior in water resistance to other roofing materials. On the roof, under the influence of sunlight, cellulose fibers bond even more tightly, which makes ondulin more resistant to water.

A standard sheet of ondulin is 2 meters long, 96 cm wide, and weighs 6.5 kg. It ignites at temperatures from 230 to 300 degrees. Because of this, it is not recommended for use in kindergartens, schools and medical institutions.

This material can collapse under a load of 960 kg per 1 m2. But first, it is not the ondulin itself that falls apart, but the rafters and lathing on which it is attached.

Warranty period of this material- 15 years.

What is the superiority of ondulin

Water resistance. Sheets of this material are impregnated with a special solution that provides water protection and does not allow moisture to penetrate inside. When laying ondulin, the nails must be driven into the highest point of the wave, which will prevent rain from penetrating through the roof in this place. Raindrops will flow down like a slide. The ondulin sheets must be laid overlapping, which will make the coating airtight.

The coating is environmentally safe and hygienic. Rainwater flowing from an ondulin roof is very clean and can be used for economic needs, for example, for washing.

Ondulin is not afraid of acid and alkali, and it is not afraid of petroleum products (gasoline). Its manufacturers claim that fungi and various microorganisms cannot live in the material, although this is a controversial issue.

Another advantage of ondulin is that it is very light. A two-meter sheet, about a meter wide, weighs a little more than 6 kg. This is four times less than a slate sheet of the same size. Therefore, it is not difficult to transport ondulin and you can lift it onto the roof even alone, without a partner.

Installation of the coating can be done quite quickly: laying out the ondulin sheets is easy. You won't need any special strength for the rafters or sheathing either.

You can cut ondulin with a regular hacksaw, after lubricating it with a little oil.

You can cut ondulin with a regular wood hacksaw.

The material bends well, which makes it possible to cover any, even the most bizarre roof with ondulin.

It should also be noted that its low cost is around $5 per sheet, which is significantly cheaper than metal tiles.

Silence is another advantage of this coating: neither the pattering of rain nor the trampling of pigeons can be heard, which cannot be said about a metal roof.

The material is not afraid of temperature changes, frost, does not rot or rust.

That's probably all the advantages of this roofing material.

Some disadvantages of ondulin

This material is not ideal, as it may seem, it also has disadvantages. Some defects of ondulin appear due to improper assembly, excessive savings or simple laziness.

The main disadvantages of ondulin:

Insufficient strength. People often complain that the material is supposedly not strong enough. It’s as if you can’t walk on the roof: it might break, and it might also not be able to withstand heavy snowfall. But often the reason for this is hidden in the incorrect assembly of the rafters and in non-compliance with the ondulin fastening technology. The fact is that the technology requires at least 20 nails to attach one sheet, and many homeowners save by almost halving the number of nails.

It is also necessary to observe the spacing of the lathing: it should be no more than 60 cm. With such a pitch and a slope of over 15 degrees, this material can withstand more than 900 kg of load per 1 m2. So it will definitely withstand snowfall, provided that it is laid correctly.

In the summer heat, the coating softens, so walking on the roof is not recommended: ondulin may not withstand the weight of a person and bend. And the dents on it can no longer be smoothed out. Therefore, during the installation of the roof, you must move extremely carefully along the surface of the covering.

Fire hazard. This is the second drawback of this coating. After all, ondulin is made from organic matter, and therefore it burns well. However, tin roofing is also not a hindrance to fire.

The material is not durable. This is also a controversial issue. For some, the ondulin roof begins to collapse after a couple of years, while other homeowners rejoice for 15-20 years beautiful coating. It all depends on the correct installation and operating conditions. When laying this coating, it is imperative to follow the technology and not skimp on fasteners, but do everything according to the rules.

To increase the service life of the ondulin coating, it is better to involve professionals during installation.

They will build a reliable sheathing, thanks to which the roof will withstand snow loads of up to 300 kg per 1 m2.

Ondulin sheets are laid offset.

Color change. Indeed, after some time, a roof covered with this material loses its original color, faded in the sun, and becomes dull. If this happens too quickly, it means that you got not real ondulin, but its likeness. The original one is painted before being impregnated with bitumen. But over time, it loses its original color and true coating.

Biostability is also questionable. After a couple of years, moss and fungus appear on the roof surface. As a result, the darkened places begin to turn green, just like on slate.

If you do everything according to the rules, then an ondulin roof can last a long time. However, in terms of strength and durability, it is still inferior to other roofing coverings.

Its use can be justified when there is a lack of money. In this case, the installation of sheets must be done on a solid base or on a lathing with a small pitch.

It is necessary to cut the ondulin extremely carefully, since if the edges turn out to be uneven, then it is almost impossible to process them afterwards. Due to the fact that there are no hard edges, it is difficult to match the overlaps of the sheets.

Special nails for attaching this coating also require close attention.

When hammering them in, you need to ensure that the cap snaps into place. If the nail is not driven all the way, the head will not snap into place, but if you overdo it, you will not be able to snap the plastic head into place again. A certain amount of precision and skill is required when driving nails.

Having analyzed all the pros and cons of ondulin, we come to the conclusion that it still has more advantages than disadvantages. This means that there will be demand for it, despite some negative aspects.

Ondulin and corrugated sheets are modern and very popular roofing materials. Each of them has its own characteristics, advantages and disadvantages, which we will discuss below.

After reading this article, you will have a fairly clear idea about them, and it will be easier for you to make a choice than to cover the roof.

Installation of the roof and installation of roofing material is the final stage of construction. Not only the comfort in the house will depend on the quality of the roof, but also a number of other important factors that non-specialists may not even be aware of. Let's take a closer look at the features of these two materials - ondulin and corrugated sheeting.

What is ondulin

Ondulin is produced on the basis of cellulose and bitumen with the addition of mineral fillers. Its other names are Euro slate, wavy slate, and bitumen slate. Although ondulin is produced by one company, it has a wide range of colors, good technical specifications and decent price/quality ratio.

What is corrugated roofing

Corrugated sheets are made from galvanized steel sheets, which are given a wavy profile using rolling equipment for greater rigidity. Corrugated sheets are coated with an anti-corrosion compound, then a primer, and then inner side polymer is applied, and varnish is applied to the outer one.

What is better - ondulin or corrugated sheeting?

Compared to corrugated sheeting, ondulin has greater plasticity, so it is easy to lay in hard-to-reach places and secure to the sheathing. In addition, there is no need to make a continuous sheathing under ondulin, and a roof made from it has better thermal insulation properties and does not “rattle” in the rain. Ondulin is not susceptible to corrosion, in particular rust, it is environmentally friendly and safe for humans.

The disadvantages of ondulin include its low strength, especially at high and low temperatures, a limited choice of colors and the fact that under the influence of sunlight, ondulin fades, and the color of the roof fades after a few years.

Corrugated sheeting also has a number of disadvantages: poor sound insulation - when it rains, the roof will “rattle”; It is difficult to cover roofs of complex configurations, since the corrugated sheets are large and more difficult to cut than ondulin. In addition, in hot weather the roof quickly heats up, and in winter the snow cover freezes to it.

As for the cost and service life of these two materials, there is no significant difference between them, they are light in weight, and roofing work with them is quite simple. By the way, when buying ondulin, you should choose original material with certificates, since there are low-quality fakes on the market.

Let's look at the advantages and disadvantages of each material in more detail.

Pros and cons of ondulin

Advantages of ondulin:

• low cost;
• ease;
• ease of installation regardless of the season. Ondulin sheets are attached to a wooden sheathing special nails;
• possibility of installing ondulin on old coating;
• environmental friendliness;
• the thinness and relative softness of the material makes it easy to saw and adjust to the desired size;
• high stability to the action of aggressive chemicals and fungi.

Disadvantages of ondulin:

• rapid color fading in the sun - during the first years of operation, the color changes noticeably;
• since in the process of laying ondulin quite a lot of joints are formed, any defect can lead to roof leakage;
• roughness, due to which snow can linger on the roof;
• softening when heated and brittleness at low temperatures. Due to these features, any work on the roof during hot and cold seasons can lead to damage to ondulin sheets;
• small selection colors;
• flammability at high temperatures;
• The guaranteed service life is not so high - 15 years. True, this does not mean that ondulin sheets will last only this period.

Advantages of corrugated sheets:

• relative cheapness;
• high service life. If there is no damage to the protective layer, the corrugated sheet will last up to 50 years;
• versatility - corrugated sheets can be used for devices various types roofs on buildings for various purposes;
• ease of installation. There is no need for highly qualified installers and special equipment;
• environmental Safety;
• a small number of joints during installation;
• good corrosion protection and high tightness;
• a wide range of colors, aesthetics;
• non-flammability.

Cons of corrugated sheets:

• insufficient sound insulation, increased noise during precipitation;
• possibility of condensation formation;
• on complex roof There may be problems covering curves and corners.

When choosing between corrugated sheeting and ondulin, you should take into account the advantages and disadvantages of these materials, as well as the specific features of the house being built. In addition, it is important to purchase a high-quality coating, and not a fake - only in this case will it last the period stated by the manufacturer.

Not so long ago, Euro slate was the most popular roofing material in private construction. It was used by all segments of society without exception, but why did it attract them so much? The fact is that if you compare it with its asbestos-cement counterpart, it has a significant advantage, but even so it has its drawbacks. Let me tell you a little about ondulin and its pros and cons, and you decide whether to use it as a roofing covering or not.

Features of roofing material

Euroslate came to us from France. The first product, which was released at the beginning of the last century, had a lot of shortcomings. It entered the construction market only in 1940 and since then, as production technologies have improved, it has only changed in better side. Once in the CIS countries, ondulin immediately gained wide popularity, because at that time no one had seen such a high-quality coating made of soft materials.

When purchasing ondulin, developers were of little interest in the negative characteristics of the material. The composition of the product played a major role in the acquisition; it included the following components:

• Natural cellulose was used as the main raw material
• Bitumen purified using secret technologies
• As an impregnation - polymer resin
• Fillers of mineral origin
• Natural pigments

Today, when we can talk about modern technologies pretty good things, the production of euro slate occurs as follows.

Raw materials in the form of cellulose are poured into a special container, where it undergoes pre-treatment. After this, the impregnation process begins. For this, bitumen and special components are used. Throughout the entire stage, the material is subjected to quite strong pressure, due to which the ondulin is given necessary indicators strength.

After impregnation, the product moves to molding. Here the coating is given a wavy shape, which is very similar to its asbestos-cement counterpart. Thanks to the use of natural ingredients, the finished product is environmentally friendly. Various pigments added during production change the color of the material depending on your needs, so you can create unique project with a unique roof.

Ondulin and its technical characteristics

When you come to a hardware store, it is difficult to confuse Euroslate with any other material. Its sheets have standard size 200x95 centimeters, and the thickness is 3 millimeters. The wave height is 36 millimeters.

IMPORTANT: Calculation of material requirements must be done wisely. Remember that when installing sheet material It is always necessary to use an overlap, therefore, the useful coverage area will be reduced. For one element it is 1.6 m2.

Ondulin has much less mass than asbestos-cement sheets. In the first case it is 6 kilograms, and in the second 26. These material characteristics allow you to create a simple rafter system, which can significantly save your finances. In addition to savings, the small mass of the product allows for quick and easy production installation work even alone.

Another advantage of low weight is the ease of transportation of Euro slate. To do this, you do not need to hire heavy equipment with a huge trailer; you can get by with a minibus. Delivery of the product to the installation site is also a fairly simple process; it does not take much effort and time.

Pros and cons of ondulin

All Construction Materials have their positive and negative sides.

Despite the fact that ondulin has high specifications roofing material, for example, environmental friendliness, durability, resistance to temperature changes, it has negative aspects.

• Durability. The service life of Euro slate is about 25 years. This value is indicative and correct installation, may change in big side. The manufacturer itself provides a guarantee for its products for up to 15 years. To be honest, this indicator does not make the material in question stand out much. If you need to lay a durable roof, it is best to consider metal, in particular copper and its alloys. If we compare only bitumen products, then 25 years is quite great importance when using natural ingredients
• Resistance to temperature changes. The product already laid on the roof will cope with both the sun's rays and severe frosts without any problems. But it is worth noting that when laying the roof under these conditions, serious problems may arise. If the sheets are installed in the hot summer, they acquire a very elastic structure and can stretch and blur. Installation of a deformed sheet will cause it to shrink during a drop in temperature and tear out the fasteners. When winter work bitumen becomes very brittle and can be broken when fastened
• Ecological cleanliness. IN modern world More and more people want to improve the situation of humanity and therefore use only environmentally friendly products. When laying euro slate on your roof, be sure that it is such. Multiple checks have confirmed the presence of appropriate certificates and this can be trusted. Besides positive side At this point, ondulin has minor drawbacks - a smell that appears in very hot weather. If it doesn't happen in your area during the year, then you don't have to worry
• Fire safety. The bitumen included in the composition immediately relegates the Euro slate to a low class fire safety. In the event of a fire, 230 degrees is enough for it to ignite spontaneously. During the combustion process, it emits acrid smoke, and the bitumen itself supports the combustion process on its own. As a rule, ondulin is not used on the roofs of buildings with increased fire safety requirements, but with the installation of special cuts this becomes possible. Their device divides the roof plane into separate segments and in case of fire the source of fire will be localized

Soft roofs have a fairly similar structure, so Euro slate fully possesses the same positive qualities.

• Soundproofing. Thanks to continuous lathing And soft material the sound of falling drops will be significantly muffled. This coating is suitable for people who need to relax in silence after a hard and noisy day.
• Resistance to microorganisms. Bitumen is a very resistant product to bacteria, therefore, you will never find fungus or mold on the surface, and insects will not wear it down
• Thanks to protective coating ondulin resistant to aggressive external environment
• Wide range of colors

In private construction, you can order the colors you need from the manufacturer; of course, this may affect the final cost of the material, but at the same time it will be possible to create a unique project.

Installation features

The article has already discussed some points regarding the installation process. Ideal temperature conditions for laying ondulin are in the range of 5-20 degrees above zero. Warm, but not hot weather will eliminate the possibility of deformation of the material during the fastening process, and all the properties of the material will actively help in this matter.

If you have ever encountered laying ordinary slate, then we can say that you know how to lay ondulin. The only difference from asbestos-cement sheets are the fasteners. Typically, roofing nails are used for this, but rubber-backed screws can provide a more airtight surface, so if this is an issue for you, then choose them.

IMPORTANT: Be careful when using self-tapping screws as fasteners. Screw them in slowly so that it does not damage the insulating layer. The fact is that there were cases when a self-tapping screw screwed on the vapor barrier, and a large hole appeared in this place.

Considering the elasticity of ondulin, we can say with confidence that this is its disadvantage. As a result of prolonged exposure to direct sunlight on the material, it begins to float a little and if the sheathing elements have a significant distance between them, then the coating may simply fail.

Concerning winter period, then the large distance between the beams when snow falls will be the main cause of damage to the material.

You already know that at subzero temperatures the material becomes very fragile, therefore, a snow load will simply break it. If we compare new material with the old analogue, then at this point it loses.

If, when installing Euro slate, you are missing a couple of millimeters of material, stretching it is prohibited. In hot weather, this material will stretch even more and significant cracks will appear on its surface, which will allow moisture to penetrate into the roofing pie.

A high-quality roof depends entirely on a well-assembled sheathing. If you are assembling it from boards, then all the elements must have the same dimensions, and if differences occur, it is best to grind them down or level out the unevenness with a lining carpet. When differences in plane have impressive values, it is best to change wooden elements to more suitable ones.

I advise you to use OSB boards or moisture-resistant plywood, because thanks to the sheets large sizes The process of creating a good foundation will take a matter of hours.

Even at the stage of developing a house project, roofing material is carefully selected. Depending on its properties, they are determined design features roofs and installation of roofing pie. One of modern options is ondulin. The article discusses the technical characteristics of the coating, its advantages and installation rules.

Features of ondulin, nuances of material production

Ondulin is similar in appearance to slate, but its structure is soft. Leaf shape and general rules work with roofing material is identical, but the technical characteristics and methods of laying the covering vary significantly.

The following components are used to produce ondulin:

Fiberglass;

Cellulose fibers;

Refined bitumen;

Mineral supplements;

Resins that provide plasticity;

Pigments.

The material is made from organic raw materials, which indicates its safety. Ondulin gained wide popularity in Europe and America, where there was an active campaign against the use of ordinary slate due to its asbestos content.

During the heating process, asbestos sheets evaporate toxic substances that harm human health and negatively affect the environment. Flexible slate does not have such problems, therefore it has been produced in an assortment for more than half a century and is sold in almost all countries of the world.

Pros and cons of ondulin

Ondulin has gained popularity among developers and specialists in a short period of time. This phenomenon is due to high performance characteristics and the following advantages of the material.

Durability. Guaranteed period The service life declared by the manufacturer is about 15 years. In fact, the roof covering can last up to 50 years.

Strength and endurance. The material can withstand thick blocks of snow without difficulty, provided that the sheathing is properly created. It is made for ondulin with smaller cells than for tiles and metal profiles. This is explained by the fact that during periods of severe frost the coating becomes more fragile. A reliable sheathing will prevent damage to the roofing material under the pressure of accumulated precipitation.

Ondulin is an environmentally friendly coating due to the absence of toxic components and hazardous chemical compounds in production.

Resistance to chemical influences. Neither acid nor alkali can damage the Euroslate sheet.

Light weight. Load-bearing walls the houses and rafter system are not overloaded with the roof structure.

Moisture resistance. Despite its soft structure, the material is hydrophobic. No precipitation is scary for an ondulin roof.

Plastic. Thanks to this quality, the sheets take any shape of the roofing structure.

Soundproofing. Roof covering absorbs various types of noise well, so use it additionally in the pie soundproofing material not necessary.

Competitive price.

High aesthetic qualities. This is achieved thanks to the constantly expanding range, which is represented by a whole palette of colors.

Like any material, ondulin has some disadvantages:

Reduced strength of the material if errors are made during the installation process (the sheet can be damaged under the feet of the installer if less than 20 nails were used to fasten one Euro slate, and the sheathing cells are made at large intervals);

Towards creation rafter system are presented high requirements(for example, if the roof slope is less than 10 degrees, it is recommended to make the sheathing continuous);

Fire hazard (raw materials of organic origin are not able to prevent the spread of fire);

Low resistance to microbiological processes, in particular to the development of fungus;
