In order to find out which building material is better, ondulin or corrugated board, you need to determine what each of them is.

Ondulin is a sheet of bitumen that has a wavy shape. It is also called bituminous slate or euroslate.

The professional flooring is the pro-thinned-out sheet from steel.

To give the corrugated board a wavy shape, the cold profiling method is used.

This is done on special equipment in order to increase the rigidity of the material. The profiling process begins with an anti-corrosion coating of the surface. Then the profiled sheet is primed, the outer side is varnished, the inner side is coated with a polymer.

When it comes to roofing, the question arises of how to cover the roof: ondulin or corrugated board. The choice of one or another material depends on their characteristics.

Advantages and disadvantages of ondulin

Ondulin, unlike corrugated board, is flexible and plastic. It can easily be laid in the most inaccessible places of the roof. In addition, it does not crack during fastening with nails. Installation of ondulin can be carried out without a continuous crate. The roof of this building material has a very high sound insulation and thermal insulation. Ondulin is resistant to corrosion and rust. It is safe and harmless to humans.

Ondulin is of two types: tile and slate. In terms of quality, these materials practically do not differ, but they have a different sheet size. Slate is used for simple designs roofs.

Benefits of ondulin:

low cost;
small mass;
simple installation process;
environmental friendliness of the material;
flexibility of shape and the ability to change the size of each sheet (it is easy to saw).

But there are also disadvantages of this material. The most significant disadvantages of ondulin are its instability to fire and a low choice of colors. Under the influence of sunlight, ondulin fades over time. Even with minor flaws during roofing, unwanted joints can form, causing leakage. When choosing this material, you need to make sure that it is not a fake. To do this, you can ask the seller for the appropriate certificate.

Advantages and disadvantages of corrugated board

The main advantages of corrugated board are:

long service life of the material;
profitability;
resistance to corrosion;
universality;
the minimum number of joints during installation;
high resistance to environmental influences;
environmental friendliness;
a large selection of colors and shapes of material.

The disadvantages of corrugated board include low sound insulation and the formation of condensation on it. It is very difficult to work with this building material in hard-to-reach places on the roof, namely in the corners of slopes and various roundings.

Decking or ondulin. Application in construction

Even taking into account all the shortcomings of corrugated board and ondulin, these building materials are of very high quality. Therefore, low noise insulation or high flammability are not the main disadvantages. It is much more important today that they, in relation to strength and durability, have a low price.

When choosing between corrugated board and euroslate, you need to study well the advantages and disadvantages of each of them. Then choose the material that is most suitable in terms of characteristics for laying a particular roof.

At first glance, it may seem that less money will be spent making a roof from ondulin (due to a small difference in price compared to corrugated board). But after the completion of all work on the installation of roofing and the calculation of all the funds spent on this, this savings on material may be in vain in the future.

In the process of working with a profiled sheet, fewer joints are obtained than when working with ondulin. This is due to the fact that the length of one profiled sheet can reach 6 m. But during rain, it creates a lot of noise, and it can also rust at the attachment points. Ondulin was not previously intended for residential buildings due to some of its qualities. But in many countries it is used precisely in the construction of a residential building. Ondulin sheets are quite light, and they can be easily lifted to the required height. You can fasten them with the most common screws. They are usually fastened to a wooden crate with nails.

Decking or ondulin. Material Features

Ondulin is a thin material, so it is easy to cut it with a hacksaw. At the same time, the hacksaw must be lubricated with oil so that it slides well and does not get stuck. Ondulin is resistant to the destructive action of bacteria and various acids. But its surface is rough, so it prevents the snow cover from slipping. This is also a huge disadvantage of bituminous slate, since the strength of this material is not great enough to withstand a large number snow. The service life of ondulin is approximately 20 years.

When installing a roof made of ondulin, you must strictly follow the installation instructions, since it takes into account the features of this material.

Decking is the most popular building material today. The profiled sheet has an aesthetic appearance and a sealed surface. But in summer it heats up quickly, and in winter snow freezes to it.

Profiled sheets can be used not only in the construction of the roof, but also for the construction, for example, of a fence. The profiled sheet differs in width and shape of the finished sheet, in the height of the corrugation. During the installation of roofing from this building material, various additional steel elements are used (wind cornice, corner strip, snow barrier, etc.)

At the same time, a waterproofing film must be laid under the profiled sheet. It can be of two types: vapor-tight and vapor-permeable. Lay such a film parallel to the eaves. The joints are glued with adhesive tape. In order for the roof space to be ventilated, a ventilation gap of 45 mm is left between the crate and the film. At the same time, rafter strips 20 mm thick are nailed onto the waterproofing film.

Ondulin or corrugated board occupy a worthy place in the modern construction market. And what to use personally depends on the specific installation conditions. And now you know the main qualities and advantages. Good luck!

A variety of coatings are presented in a wide range and belonging to different price categories: from budget to expensive options. At the same time, the attention of buyers is concentrated not only on the price, but also on the quality of the purchased goods. Among the available, but relevant to all technical requirements, operational characteristics include ondulin, the pros and cons of which are to be studied today.

Invention and production of this roofing option

In more than 70 years of industrial evolution, this material, invented in 1946, has received considerable fame. The first batch of ondulin was released by Gaston Gromier and literally "thrown out" on the market. At first, the consumer sector was wary of such a novelty, but a year later the factory launched all production facilities. They were aimed at the production of ondulin coating, which became popular not only in domestic open spaces, but also in neighboring European countries. It began to be actively exported.

Ondulin and domestic industry

The Russians became aware of ondulin only at the end of the last century, when it was impossible to say about the domestic consumer that he was spoiled for quality cheap goods and building materials. It was the described material that became the product that showed in practice that imported goods are not always characterized by high cost. This period is characterized by a construction boom associated with the replacement of traditional slate with an alternative and no less reliable option - ondulin, the pros and cons of which have already been evaluated by many buyers.

The world's best material manufacturers

Thanks to the quality of their products, about which there were rarely negative statements, and the cost of the material, the French mastered the world market in record time, selling not only materials, but also the technology for manufacturing onduline coatings. This is what made the material sold under various brands available today. Among the quality, according to buyers, characterized by mass positive properties ondulin, production:

France - Onduline;
Belgium - Aqualine;
America - Nuline;
Turkey - Corrubit;
Germany - Bituwell.

When choosing a manufacturing company, it is worth considering that the sheets of material for each supplier differ in size. So, giving preference to one or another brand, remember this so as not to make a mistake when calculating the required amount of material.

Technical characteristics of ondulin of domestic production

The length of ondulin sheets is 200 cm, width - 95 cm, thickness - 0.3 cm, wave height (corrugations) - 0.36 cm. The weight of a standard sheet is 6 kg, which is 20 kg lighter than a conventional sheet of asbestos slate. The strength characteristics of ondulin are not inferior to ordinary slate and even surpass it, and installation is characterized by simplicity.

Ondulin is supplied to the market in the form of sheet plates, completed with fasteners in the amount of 20 pcs. for 1 item.

What is this material made of?

During production, raw materials are processed under high pressure and temperature. Ondulin contains:

fiberglass;
cellulose fibers;
refined bitumen;
mineral compounds that replace the filler;
mineral pigments that color the material;
thermoset resin.

Ondulin reviews: pros and cons according to buyers

The consumer sector is interested in what advantages and disadvantages this or that type of material has. First of all, those who are going to purchase building materials pay attention to the recommendations and reviews not of consultants and sellers, but of those who, like them, once faced a choice and have already tested ondulin on their own roof.

From the reviews and recommendations of customers on the Internet and on the forum about ondulin, the pros and cons of the material, as well as other performance characteristics of the material, we chose the most interesting ones, clearly emphasizing the pros and cons. They are marked by hundreds of buyers across the country. And they summarized them into two groups, which characterize ondulin better than others as roofing material.

So what are the pros and cons of ondulin?

The positive aspects of using the material

Among the advantages inherent in ondulin, the following characteristics:

The plasticity of the material, which allows it to survive various kinds of loads. So, when hammering a nail, don't worry about the surface cracking. The bitumen-containing composition of the sheets relieves the buyer of the need for additional impregnation of the material for the roof slope with sealing compounds intended for filling mounting holes. Bitumen itself is an excellent sealer.
Ondulin is resistant to small mechanical damage, for example, to scratches.
This is one of the best silent roofing in the world today.
Under the action of sunlight, ondulin practically does not heat up, which allows it to be compared with a ceramic coating, although it is inferior to metal products.
Ondulin - a roof covering, characterized by excellent thermal insulation properties. Although it is impossible to say that ondulin is suitable as an alternative replacement for any material.
Moisture never collects under a layer of ondulin, which means that the possibility of condensation is practically excluded.
On the surface and under it, colonies of harmful organisms, for example, fungi, do not form. Together with frost resistance and resistance to sunlight, temperature and humidity changes, this roofing material can last up to 25 years, as the manufacturer claims. From this it turns out that the pros and cons of ondulin also affect the service life of the coating, which depends on the quality of the material and production technology.
Ondulin is an environmentally friendly material consisting of natural components. In addition, it can be painted in any color, at the request of the buyer, so it will suit any landscape design, organically fitting under it.
The light weight of the sheets, which is important for a number of reasons:

there is no need to strengthen the entire roof structure or its individual sections: truss system and crate;
working at height with such material is simple and easy, you do not have to ask a neighbor or friend for help, because you can cope with raising the sheets to the roof on your own, without risking the safety of either your own or the people around you;
this material is easier to store and transport even in the trunk of your own car, which will fit up to 50 sheets of ondulin, the total weight of which will be no more than 300 kg.

Some material flaws

Now familiarize yourself with the cons of ondulin, and take note of the pros. This will come in handy both when choosing a material and at the execution stage. installation work, which, by the way, are easy to do with your own hands without the help of specialists, which provides an opportunity for additional savings.

Not all manufacturers guarantee flawless appearance of your product throughout the entire operational period. Burning of the surface is not excluded. This process is characterized by gradualness, and its intensity depends on the type of pigment and its color. So, brown and red colors fade slowly, gradually changing their shade to a duller one.
The roof of the house can also be spoiled by uneven distribution of bitumen, leading to uneven burnout. As a result, the roof becomes spotty and far from aesthetic.
The pros and cons are very contradictory due to the velvety structure of the coating, which, when constantly in the shade, becomes a favorable "soil" for the development of moss and other green vegetation.
Caution - the material is flammable. This is one of the biggest downsides to coverage. The pros and cons of ondulin and tiles in this regard are obvious, since in this respect the buyer gives preference to the last of the options. When heated to +200 ° C and above, ondulin is prone to spontaneous combustion.

Summarizing

As you can see, this material is not without errors, but are there any flaws in slate, tiles, and other roofing materials? What exactly to give preference to is up to you. Construction is a serious matter, and the roof is the foundation that protects the future house from above, and who knows if in a couple of years they will not invent a coating even better than those on the market, but for now, ondulin firmly and confidently holds its position in sales, being the best alternative roofing finishing material for outdoor use. Now blocking a house, bathhouse, gazebo, garage or other building is simple, reliable and inexpensive with the help of ondulin.

Private developers often face the question right choice roofing material. After all, everyone understands that the durability of the structure and the effectiveness of protecting the entire structure from adverse natural phenomena depend on this. In the modern market for roofing materials, huge selection metal, polymer and bituminous coatings. Wide range of colors and textures is able to satisfy any, even the most sophisticated taste.

In addition, roofing materials can be selected according to wealth, which in some cases is of great importance. Among a large number of roofing materials, there are options that belong to the same price category, for example, ondulin or metal profiles. To understand which of the presented materials is better, you need to familiarize yourself with the advantages and disadvantages, as well as the performance characteristics of each of them.

Description of ondulin - advantages and disadvantages

One of the modern roofing materials is ondulin. This coating is made on the basis of cellulose, which is impregnated with a polymer substance and coated with bitumen during the production process. All rights to the production of this material belong to the company of the same name, which is registered in France. At one of the stages of production, the pulp-polymer mass is subjected to molding, giving it a wave-like profile, then the resulting material is cut into sheets of a standard size. For coloring ondulin, various coloring pigments are used. The surface of the material is soft and rough. The weight of a standard sheet is about 6 kg.

The advantages and disadvantages of ondulin include the following:

Flawless operation for 25-50 years, certified by the manufacturer. Compared to other roofing materials, this is a fairly long time.
Acceptable cost. Ondulin is an economy-class roofing material, but its appearance is not inferior to more expensive counterparts.
Light weight. The lightness of the material has great importance, since the cost of installing the crate depends on this.
High strength characteristics. Ondulin is able to withstand a significant snow load, the thickness of the snow layer on the roof of this material can reach 50 cm.
Low thermal conductivity. The material does not transmit heat, therefore, frost, icicles and condensate will not form on its surface. In addition, heat loss through such a coating is minimal.
Security. Ondulin does not contain components that can harm human health and life. This has been proven by numerous studies.

But even listed virtues material does not allow to say that it is an ideal roofing material.

First, assembly or repair work can be carried out at a certain temperature, from +5 to +15 0 C, since when heated, the material loses its strength, and at a negative temperature, its fragility increases.

Secondly, the material has a special composition and structure, due to which the shortcomings of ondulin are determined:

A very important disadvantage of ondulin on the roof is rapid ignition. The presence of cellulose in the composition of ondulin explains its ability to ignite.
Poor UV resistance. The sun's rays can spoil the appearance of the material, and burnout occurs unevenly.
Accumulation of snow, dirt and dust. The material has a rough surface, so dirt and snow do not roll down on it. Therefore, a roof covered with ondulin requires regular cleaning.

Having studied the advantages and disadvantages of ondulin, you should get acquainted with the similar characteristics of the profiled sheet.

Features and advantages of corrugated board

The professional flooring represents a thin metal sheet with the applied profile. Due to the corrugated surface, the material has a high transverse rigidity. For the production of corrugated board, sheet steel is used, protected by an anti-corrosion alloy based on zinc, aluminum or molybdenum. In addition, the surface of the material is coated with paint or protective polymers. Depending on the thickness of the base and the applied coating, 1 m 2 of corrugated board weighs 6-8 kg. It should be noted the high resistance to ultraviolet and rust, as well as to destruction from biological factors and to mechanical stress.

The advantage over other roofing materials is provided by the presence of the following properties:

Operation for half a century with the preservation of waterproofing characteristics, provided correct installation and quality service.
Fire resistant. This property makes it possible to use the material for the construction of the roof of a bathhouse and buildings with stoves and fireplaces, which the high combustibility of ondulin does not allow.
The ability to withstand significant loads. The corrugated surface with additional stiffening ribs allows the material to resist heavy loads from accumulated snow.
Surface smoothness. Thanks to this property, dirt and snow mass roll off the roof. In addition, ridges parallel to the slope guide the melt and rain water into the gutter of the drainage system.
Burnout resistance. This property of corrugated board allows you to keep the color of the roof and its attractiveness throughout the entire operational period.
Acceptable price. Compared to other metal roofing materials, corrugated board occupies a more advantageous position, therefore it is very popular.

Like ondulin, the profiled sheet has some nuances that characterize it from a less attractive side:

Firstly, the material is based on metal, which has a fairly high thermal conductivity. Therefore, the use of corrugated board for the roof of a house with a residential attic room requires laying an additional thermal insulation layer. It is worth noting that the insulation of the roof slope helps to solve the problem of overheating of the attic in hot weather.
Secondly, metal surfaces are characterized by high resonant properties that can amplify wind noise, the sound of raindrops and hail. The solution to the problem is soundproofing the roof.
Thirdly, even such a durable material requires care in work, since the anti-corrosion coating can be easily damaged by careless handling.

The main selection criteria - cons of materials

The main factor influencing the choice of roofing material is the taste and preference of the owner, since each coating has its own positive and negative properties.

When choosing ondulin or corrugated board, which have almost the same service life and are completely safe for humans, a few points should be highlighted:

By weight, ondulin has lower indicators than corrugated board, which is especially important for a weak truss system or for buildings on a foundation with low bearing characteristics.
In the case of a fire hazard, corrugated board has advantages. But if preventive measures are taken in advance, then this minus of ondulin can be ignored.
One of the advantages of ondulin is its high soundproofing properties, which cannot be said about the profiled sheet.
Comparing the ease of installation, it can be noted that for roofs of complex construction it is better to choose ondulin, since it is more flexible and can be easily cut with a knife. Simple rectangular slopes are more convenient to cover with corrugated board.
Laying ondulin can be performed by anyone without special building skills. Decking in this regard can cause some inconvenience, as it requires the skill of working with a special tool.

Today, few developers will not pay attention to the multi-colored elements of ondulin. Products have firmly conquered the market due 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 euroslate, paying tribute to aesthetics and practicality. Let's look at the advantages, disadvantages and varieties of coverage in more detail.

Roofing was invented more than 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 corrugating at a temperature of +120 C. After that, the elements are coated with paint and impregnated with bituminous compounds with polymer additives.

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

Basic material characteristics

The standard sheet is available in sizes 200-95 cm, thickness 3 mm. Wave height (corrugations) 36 mm. Taking into account the fact that when laying the sheets are overlapped, the useful area of the roofing material is 1.6 m. To select the material and correctly calculate the required amount, you need specifications ondulin - roofing, which has a stable shape, it will not be difficult to calculate the required volume.

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

Advice! The light weight of the roofing sheet allows you to do without additional miscalculations of the supporting structures necessary 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 roofing 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.
The load that destroys the material is 0.96 t/1m2. In this case, it is not the sheet itself that is destroyed in the first place, but the crate and the truss system.
Chemical resistance is high. No other material tolerates alkalis, acids, oil products like ondulin, the characteristic of the material is suitable for covering roofs in environmentally disadvantaged areas.
The presence of a hygienic certificate confirms the high hygienic performance.

Good water resistance and a warranty period of 15 years complete the main characteristics of the material.

Benefits of ondulin

Considering the pros and cons of ondulin, you 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:

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

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

Roofing disadvantages

But ondulin has disadvantages, often forgotten by manufacturers presenting the product as one of the best roofing. Most of the negative aspects are manifested due to improper installation, but still there are certain disadvantages:

Strength. It is low, but if the installation technology is violated, in particular, less than 20 nails are driven into the sheet, then the strength of the element will noticeably decrease. With a normal crate with a step of 0.6 m and a slope above 15 °, the sheet can withstand up to 800 kg / m2.

Important! During a period of intense heat, the coating should not be walked on so that the sheets do not sag, in addition, the release of odors of bituminous impregnation is not ruled out.

fire hazard- another minus that ondulin has, the properties of cellulose as an organic material do not exclude the possibility of fire.
Durability is always questioned, despite the 15-year warranty period. It all depends on the correct installation and operating conditions of the facility. In extreme conditions, only the best metal roof can withstand, but every developer is able to follow the laying technology in order to extend the life of the material.
Burnout. Time and precipitation lead to a change in the color tone of the 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, otherwise the shade will quickly fade.
Biological resistance 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 proper installation, the roofing will last a long time, but 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 offer not too diverse types of ondulin, these include:

Smart (Smart) - bituminous material having such qualities as:

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

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

Important! Decrease overall dimensions sheet - a big plus, in this case, the installation is carried out with a large number of overlaps, which gives the roof covering the necessary rigidity and resistance to increased loads.

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