Ondulin working area. Ondulin - sheet sizes. What is ondulin: specifications
Today, one of the most popular roofing materials is ondulin. resistance to loads and low weight make it comfortable to work with.
Ondulin is a wavy canvas made from compressed cellulose, which is impregnated with bitumen. Builders also call this material euroslate. Its color depends on the type of bitumen. To improve the characteristics of the material from above, it is additionally treated with thermal oils and minerals, in combination they provide protection against moisture.
Ondulin properties
1. The material is resistant to adverse effects environment. Manufacturers claim that the roof of it will serve at least 50 years.
2. The ondulin sheet weighs only 6 kg, which makes it easier to work with it and climb to a height.
3. The roof of this material has excellent heat and sound insulation properties.
4. Ondulin has an attractive appearance. A variety of colors makes it possible to choose the right shade that is in harmony with the site.
5. Flexible curved sheets are not affected by fungi, bacteria and other microorganisms.
6. Ondulin does not absorb moisture, but completely rejects it.
Scope of ondulin
Most often, ondulin, the sheet size of which allows you to accurately estimate costs, is used in private construction. It can be found on the roofs of both small cottages and two-story houses.
Recently, ondulin is found on multi-storey residential buildings, schools and clinics. Builders choose this type roofing material because of the ease of installation.
Ondulin can also be seen on the roofs of small trade pavilions and shops. The choice of roofing material in this case is explained by the possibility of laying it on top of the old slate. This way of updating the roof can be done without closing the store.
Standard dimensions and weight of an ondulin sheet
The convenience of using ondulin lies in the standardization of the dimensions of the sheets of material. This allows you to accurately calculate its consumption.
On curved and curved roofs, it is best to use ondulin. The dimensions of the sheet, the usable area of which is always less than the overall area, are 950 x 2000 mm. The width tolerance is ±5 mm, the length tolerance is +10 mm. Sheet thickness - 3.0 mm. Wave height - 36 mm. The weight of a standard sheet is 6.0 kg.
About what size of the ondulin sheet will remain useful if it is overlapped with neighboring roof elements, you need to tell in addition. with a small angle of inclination implies laying a roof with an overlap in length and width. The dimensions of the useful area of the sheet in this case are approximately 864 x 1900 mm.
It should be borne in mind that with complex bends, material consumption can increase significantly. The standard size of an ondulin sheet in this case is divided longitudinally into 2-3 parts. An overlap is made at the junction of each element.
The cost estimate for the arrangement of the roof should include not only the cost of materials and the work of installers, but also, for example, skates, gutters for rainwater and other additions.
Standard dimensions and weight of ondulin sheet "Smart"
The market for roofing materials is constantly updated with new products. This also applies to ondulin. It is gradually being replaced by a new generation of Smart roofs.
The improved ondulin differs from its predecessor in the presence of markings on the sheet. The embossed strips help to make the installation more precise. Ondulin "Smart", the sheet size of which has become slightly different, allows you to reduce the amount of overlap by about 50 mm (from 170 to 120 mm). This measure makes installation easier.
The specially designed Smart Lock system slightly changed the dimensions of the sheets to 950 x 1950 mm instead of 850 x 2000 mm. At the same time, the usable area has increased. The weight of the improved material sheet is already 6.3 kg instead of 6.0 kg.
The roofing material developed by the French company ONDULINE has been considered one of the most popular in its field for half a century. Today it is produced in many countries, and Russia is no exception.
Despite the great demand, not everyone knows what the useful area of \u200b\u200bondulin is, but meanwhile 
this information is necessary in order to make an accurate calculation of the estimate. Incorrect data often leads to a shortage, and then people are forced to buy more material. Of course, there is nothing fatal in this, but it is worth knowing that different batches differ in shade, and as a result, the risk of color mismatch increases.
What you need to know about ondulin
This material is considered a high-quality coating and is able to reliably protect your home from rain and snow, if all the laying work has been carried out correctly. The service life is at least a quarter of a century. Moreover, the manufacturer gives a guarantee for the product for 15 years.
The cost of ondulin is about 40 percent higher than that of traditional slate. Therefore, with limited finances, it is advisable to take the latter. In addition, in the same price range, there are several options for modern roofing materials that have similar characteristics and proper quality.
Ondulin copes well with sudden changes in temperature, but at the same time softens in the heat, while in the cold it becomes quite fragile. The latter circumstance explains the ban on working with this coating in the winter.
According to the manufacturer, the material is able to withstand:
- hurricane (up to 200 kilometers per hour) wind;
- a large amount of snow (more than 300 kg per square meter of roof);
- hail;
- showers.
It also has good soundproofing properties. This makes ondulin preferable if it is planned to arrange an attic in the attic. Flexibility and lightness make it much easier to work with it - even an unprepared person can handle it alone.
Since ondulin contains only natural materials, it is completely safe.
Its undoubted advantage is its rich color scheme.
A significant disadvantage of ondulin is its poor fire resistance. Already at temperatures above 230 degrees, it can ignite. And after that, it burns on its own, releasing a lot of suffocating smoke. For this reason, it is necessary to carefully weigh the pros and cons if your house is heated by stoves. The company recommends in this situation to isolate pipes from ondulin with special aprons and spark arresters.
Among other things, the coating also burns out, since the manufacturer uses natural pigmenting substances. In this case, color saturation is often lost fragmentarily, as a result, spots appear on the roof surface. In such cases, the roof is simply repainted.
Over time, bitumen may appear on its surface. This company does not consider marriage.
Sheet dimensions
Currently, three variants of sheet metal are supplied to the Russian market. roofing ondulin. They differ in:
- appearance;
- design features;
- usable area.
For example, Smart tiles have special locking systems. At the same time, DIY has fewer waves than the standard sheet. And the Compact option has a small area compared to other products.
Useful is the area of the roofing material, excluding overlaps, both end and side. Knowing this value allows you to accurately calculate the amount of ondulin for your particular roof.
It is only worth noting that the usable area of the same material may differ, depending on what is the slope angle of the roof slopes. The larger it is, the smaller overlaps need to be done.
On steep roofs, ondulin is placed on top of the previous sheet by 1 wave, while on gentle roofs - by 2. This approach is needed in order to protect the house from leaks to the maximum, because water drains quickly from a sharp roof, and from those whose angle of inclination minimal - very slow.
This rule does not apply only to Smart tiles. It is equipped with a special lock, which ensures tightness in any case. The size of the sheet mentioned above is 1.95 meters by 96 centimeters. The area, respectively, is 1.56 square meters (1.9 by 0.864 m).
Ondulin DIY has dimensions of 2 by 0.76 meters. The useful area, depending on the steepness, slope varies. So, if the angle is more than 15 degrees, then:
- longitudinal overlap - 1 wave;
- transverse - 170 mm;
- usable area - 1.22 sq. m.
More than 10 degrees and not less than 15:
- 1 wave;
- transverse overlap - 200 mm;
- area - 1.2 square meters.
The slope is gentle from 5 degrees to 10:
For a standard ondulin, the size of which is 760 × 1950, the usable area is calculated in the same manner.
Ondulin Compact has a length of 1 meter and a width of 76 cm. Its usable area with:
- 27 and more degrees of slope - only 57 cm2;
- from 17 to 27 - 53;
- 10-17 – 50;
- 5-10 - 40 cm.
It is also necessary to mention that the height of the ondulin wave is 3.6 centimeters. There are 10 bends in a standard sheet, each step is 9.5 centimeters.
For those who do not want to bother with calculations, it is possible to calculate the exact amount of ondulin on the official website. There is a special calculator that will also indicate the number of all necessary additional elements.
What is the useful area of \u200b\u200bondulin and one of its sheets
The useful area of one sheet of slate or ondulin tiles is an important parameter that allows you to accurately calculate how much material you need to buy for the roof. All main dimensions are given in this article.
Ondulin sheet dimensions and its useful area
Sheet material, developed by the French company ONDULINE, has been among the popular materials for arranging roofing for more than half a century. Today, ondulin is produced in many countries of the world, including Russia. Due to the peculiarities of the manufacturing technology of the material, the color shades of different batches may vary slightly. In order for the appearance of the roof to be aesthetic, it is recommended to use roofing material from one batch, having previously accurately calculated the required number of sheets.
Characteristics of ondulin
Ondulin is actively used in the construction of capital facilities - residential, commercial and industrial buildings, in the construction of light structures - pavilions, kiosks, sheds, gazebos. Due to its low weight, this sheet material is ideal for repairing old roofs: it can be mounted on top of flat, old roof coverings without fear of unnecessary load on the foundation of the structure. The approximate load of the new flooring will be about 3 kg per 1 m 2.
The manufacturing technology of the material is quite simple: cellulose fiber is pressed into corrugated sheets resembling traditional slate in shape. Then the base is impregnated with bitumen, upper layer material is covered with a layer of mineral pigment and cured resins. The small thickness of ondulin makes it easy to install - sheets can be easily lifted onto the roof, cut, used for laying on curved surfaces, since the material bends both in the longitudinal and transverse directions. The total area of a standard sheet is 1.9 m 2 .
The benefits of ondulin include:
- long service life (warranty - 15 years, actual service life - 50 years);
- attractive appearance;
- resistance to moisture and atmospheric influences (heavy wind up to 200 km/h, temperature from -40 to +80°С);
- high noise absorption coefficient;
- simple installation;
- resistance to biological destruction, the effects of acids, alkalis, oils;
- ability to withstand loads up to 300 kg/m 2 .
Ondulin, unlike standard slate, does not contain harmful substances and does not provide negative impact on health.
Ondulin dimensions
On the Russian market, ondulin, manufactured under license from a French company, usually goes on sale. The length of a standard sheet is 2000 mm, the width is 950 mm, the thickness of the ondulin is 3 mm, the wave height is 36 mm. The permissible error can be +10/-3 mm in length, +5/-5 mm in width, +2/-2 mm in wave height.
Each sheet of ondulin has 10 waves with a width of about 95 mm, which must be taken into account when calculating the material for covering the roof. When installing a horizontal row, it is necessary to overlap one wave wide to ensure the strength and tightness of the flooring. The vertical overlap when laying ondulin on the roof, the slope of which exceeds 15 degrees, must be at least 100–150 mm. As a result, the useful area of one sheet element reaches 1.60–1.64 m 2.
If ondulin is laid on a roof with a small slope, the lateral overlap of the sheet should be 2 waves, and the vertical overlap should be about 200 mm, which requires a special calculation of the usable area sheet material.
Before purchasing ondulin, it is important to calculate the roof, taking into account the useful area of \u200b\u200bthe sheet material, so that in the future you do not have to buy products from another batch.
Roofing calculation principles
Gable roofs with a slope angle of 15 degrees or more are the easiest to calculate, each slope of which is a rectangle, and the overlap parameters are standard. In this case, it is required to calculate the roof area and divide it by the usable area of one sheet of ondulin - 1.6 m 2.
If you need to calculate a complex roof, then you need to divide it into separate planes - rectangles and triangles, calculate the coverage area for each plane separately and sum it up, adding 5% for installation waste.
When calculating materials for the roof, one should also take into account the presence of windows in the roof plane, the use of elements such as a valley, a ridge, covering aprons, an eaves gutter, roof ventilation elements and other components of the roofing system. Their presence and quantity affects the calculation of ondulin sheets.
The need for accurate calculations
Obviously, in comparison with the total area of a standard sheet element, a difference of approximately 0.3 m 2 is gained from each sheet of ondulin, and if this is not taken into account, the purchased material may not be enough to install the entire coating.
A competent approach to the calculation of ondulin roofing, taking into account the dimensions of the sheet elements, will help to avoid problems associated with the acquisition and delivery of the missing material, which entails not only additional transport costs, but also disrupts the work schedule. In addition, a new batch of ondulin may differ in shade from the existing one, which will worsen the overall appearance of the roof.

Useful area of an ondulin leaf.
Roofing materials Ondulin are represented by three types of sheets, differing in design, dimensions and usable area. So, for example, Ondulin Smart sheets are equipped with a “smart” Smart Lock, Ondulin DiY sheets have fewer waves, and Ondulin Compact sheets, as the name implies, have small size.
The useful area of the ondulin sheet is the area without side and end overlaps. Knowing the useful area allows you to quickly calculate the required amount of roofing materials, for this it is enough to divide the total surface area of \u200b\u200bthe roof by the useful area of one sheet. The useful area of the ondulin sheet depends on the slope of the roof. With an increase in the angle of inclination, the useful area of roofing materials increases, and when installed on sloping roofs, it decreases.
The change in usable area is due to the following reasons:
- at large angles of inclination, ondulin is mounted with a side overlap in one wave, and at small angles of inclination, the side overlap is two waves;
- with an increase in the angle of inclination of the roof, the end overlap of the sheets increases, and decreases with a decrease.
An increase in the side and end overlaps is necessary in order to prevent leakage during heavy rainfall, with slanting rain and strong crosswinds. In addition, large overlaps prevent leakage during the formation of lenses from melt water.
The Smart Lock lock is an additional obstacle to water, so the end overlap of Ondulin Smart sheets remains unchanged at any angle of the roof and is 12 cm.

Useful area of an ondulin sheet
Currently, three types of Ondulin roofing sheets are produced: Smart, DiY and Compact. Their main difference is dimensions. The useful area of the ondulin sheet depends on the angle of the roof.
Useful area of ondulin
Almost all residents of private houses appreciated the advantage of bituminous slate. It is worth noting that this coating gained its popularity in just a couple of years, when most materials reach such heights only after 20-30 years. Such a phenomenal success is justified by the fact that the vast majority of private developers erected only gable truss systems, and slate was used as a roofing material. In Europe, ondulin is called euroslate, and if you compare these products, you will notice that there is practically no difference, but the properties differ significantly. In this article, I will explain to you how the useful area of \u200b\u200bondulin is calculated, highlight the strengths and weak sides this material and describe technological process styling.
Where did the name ondulin come from and how it is created
It is not difficult to understand where such a name came from if you are at least a little versed in English letters. Material under the brand name "Onduline" was released by a French company more than 70 years ago. Such a significant period did not reduce the popularity of the material in any way, but on the contrary, it consolidated its position. If you didn't know, then the residents European countries products are chosen very carefully, regardless of the area in which they will be used. As for our country, here people try to keep up with a more profitable acquisition, very often ignoring its harmful sides.
An example is asbestos-cement slate. It has been used for several centuries, but only a few decided to abandon this product and began to look for a suitable alternative. There is nothing strange that it turned out to be ondulin. The composition of this material includes a large number of components that are safe for human health. If you do not know how the release of euroslate sheets takes place, then I will tell you now.
- At the very beginning of production, a sufficient amount of pulp is harvested. At the same stage, it is cleaned of debris and various impurities that can change the properties of the final product. After this process is completed, a special solution is added to it, making the cellulose very soft. The resulting substance is called pulp.
- The pulp moves along the belt and enters the conveyor, where it is rolled out on the surface with a certain thickness. Moving on, it dries up, hardens and, through heat treatment, acquires an inhomogeneous body.
- Modified bitumen is applied to the resulting cellulose mass on both sides and, after hardening, the material is stored from the pack.
- After the accumulation of the required number of sheets, they are packed and sent for sale.
As you can see, many secondary processes are omitted here, about which only a plant worker can tell, but I hope the approximate scheme for the production of ondulin is clear to you. 
How to calculate ondulin on the roof
The calculation of ondulin on the roof is not a difficult task at all, it is almost identical to finding the right amount of asbestos slate. Standardization can be attributed to the distinctive features of this material. At whatever plant it is produced, ondulin will have constant dimensions. This factor can affect the definition of a quality product, for example, if you happen to meet euroslates of different sizes, then know that you have a fake in front of you, and, therefore, no one is responsible for the quality.
Define good quality ondulin can be on the following grounds:
- The width of the sheet is 950 millimeters. Such small dimensions give convenience when laying on a small or medium area.
- The length is exactly 2 meters. This value was taken based on the length of the most popular slopes, as a rule, it is a multiple of two.
- The thickness of the material is no different from that which was at the production stage and is 3 millimeters. The manufacturer of ondulin warns that this parameter may fluctuate insignificantly, so you should not look for any decrease in quality here.
- Each sheet wave should have a height of 36 millimeters.
- The weight of a standard euroslate is 6 kilograms. As for onduvilla, coverage in 1 square meter will weigh 4 kilograms.
- The area of each sheet is 1.9 square meters.
There is only one way to find the useful area of the material. To do this, the area of \u200b\u200bthe sheet is taken and horizontal and vertical overlaps are taken away. The resulting figure will show the required area. By the way, for a standard ondulin sheet, it will be 1.6 meters.
Advantages and disadvantages of euroslate
Despite the fact that the material was made to replace the harmful asbestos slate, it still has some drawbacks that negatively affect its popularity. The most pronounced problems include severely limited installation conditions. You can work with this material only in warm weather, somewhere in +10 +25 degrees Celsius.
If the temperature drops below the first value, then the bitumen included in the composition will begin to coarsen and lose elasticity, and as a result, it will simply begin to crumble. In the opposite situation, the ondulin sheet will acquire an overly flexible state, as a result of which the material will sag under its own weight, which is unacceptable for roofing. In addition, euroslate is laid on a continuous crate. All these indicators can become critical when considering this product.
In case you are going to lay this product on a farm building, then be careful, as it does not have fire safety. The body of the ondulin is able to withstand only 110 degrees, after exceeding this value, it begins to deform. In the event of a fire, euroslate will keep burning for a long time, so it cannot be used as a coating on baths, woodsheds and other similar buildings. 
Now let's talk about the good. The advantages of ondulin are as follows:
- Small mass. The lightness of this product greatly affects the possibilities of its installation. Euroslate can be laid on top of the old coating without dismantling it. For this, the base is prepared (garbage and vegetation are removed), and a simple system of bars is created on top, which will be the basis for the new material.
- High service life. Despite the fact that bitumen is present in the composition of ondulin, this product can withstand more than 100 freeze and thaw cycles. This suggests that the minimum service life is 25 years, but in fact this value reaches 40. Reviews written on various construction portals will help to believe in these numbers.
- High strength index. The rigidity of the ondulin sheet is set by a wavy body. Thanks to this structure, it can withstand a load of up to 300 kilograms per square meter of snow cover.
- As you know, bituminous products are distinguished by their very high waterproofing and ondulin was no exception. For the entire time of operation, you are unlikely to have a situation where, with the full integrity of the roof, it will leak. In addition, euroslate does not contribute to the appearance of condensate, which is a definite plus.
- Dense leaf structure and its shape easily reflects all noises, so by placing ondulin on the roof surface you will forget about annoying sounds and will be able to concentrate on anything.
If you weigh all the pros and cons, then the material shows itself in a double light, so buying it or looking for something else is up to you. 
Nuances of installation and transportation of ondulin
As you understand, ondulin is a durable material, but as long as it is in optimal conditions. In the process of purchasing this product, it is very important to inspect each sheet of euro slate for defects. It is very important to identify cracks and chips here. In addition, pay attention to the dimensions of the sheet and the way they are stored. If violations have been noticed, then you can safely leave such a hardware store or market, here you will not find quality products.
After you have purchased the material, it must be transported to the construction site. When loading and unloading, be extremely careful. The fact is that the bitumen material is quite soft in its structure and with a strong impact, the damage site may not be noticeable, and after heavy rains it will begin to give slack and a gap will form there, which will cause a leak.
You can divide the material with a saw or a suitable power tool. Laying sheets should be done randomly so that their joints do not coincide. If you are missing 1-2 centimeters to the end of the slope, then in no case do not stretch the sheet and do not try to fix it in this position. After the first frost, such a leaf will simply break.
When purchasing roofing, it is very important to know its dimensions and the required quantity. A careful reading of this article will tell you how the useful area of \u200b\u200bondulin is located.

In appearance, ondulin is in many ways reminiscent of traditional asbestos-cement slate, which makes it possible to create roofs traditional styles. Through the use modern materials and technology manufacturers managed to create a very quality material By low prices, the cost of covering the roof with ondulin is one of the lowest. new material It is no coincidence that he retained the traditional geometry of the waves; in terms of all physical indicators of bending strength, this is the most successful choice. In addition, the absence of sharp changes in height and bends significantly reduces internal forces and increases the service life.
The material was first produced in France about 50 years ago by the company Onduline, hence the common name used today for this type of roofing. International standards still do not exist, each manufacturer develops its own specifications and tries to stick to them.

Specific tolerance values depend on the equipment, materials and technology used, but in most cases the deviations do not exceed the following parameters.
- Length 200 cm. Length tolerance +10 …-3 mm.
- Width 95 cm. American manufacturers produce ondulin 1.22 m wide, Belgian 87 cm. Size fluctuations in width ± 5 mm.
- Thickness 2.4–3.5 mm. Thickness fluctuation ±0.2 mm.
The fields of deviations in height and width of the wave depend on their number. All manufacturers sell a set of additional elements in the kit.
Prices for ondulin
Ondulin roofing accessories
For high-quality installation of an ondulin roof, you need to buy additional elements, preferably from an identical manufacturer. The cover kit includes the following items.
- Skate. Installed at the junction of two slopes. Depending on the specific manufacturer, the dimensions may vary slightly, but on average the length is 100 cm, the width of one side is 30 cm.
- Forceps. Are applied to a pediment and a roofing slope. Approximate dimensions 110×35 cm.
- valleys. Installed at break points pitched roof. Approximate dimensions 100×15 cm.
- Filler of open gaps of waves. Mounted on the bottom row of the coating, it prevents snow, rain, birds from getting under the roof. It is made of durable foam rubber, has holes for ventilation.
- Apron. Used for sealing roof joints with vertical architectural elements. Most often they are made of plastics, but there are also metal options.
- Nails. They are used for fixing individual sheets, they have rubber sealing gaskets.
When calculating the amount of roofing materials, these elements must also be taken into account. How to correctly calculate the amount for a particular roof, we will describe in the article a little lower.
Table. Technical specifications ondulin from various manufacturers.

An example of calculating the amount of coverage and additional elements
Ondulin is mounted on the crate, the distance between the individual slats depends on the bearing characteristics of the coating, but on average it is 25–30 cm. The more sheets and waves have a lower height, the lower the bending resistance, the closer the slats of the crate should be.
Important! When calculating the amount of materials, the angle of inclination of the slopes should be taken into account truss system. At a roof inclination of up to 15°, two sheet waves should overlap, with a larger slope, one wave overlap is sufficient. This dependence eliminates the ingress of snow under the roof. On flat roof ondulin is laid only on a continuous crate with mandatory additional waterproofing.
The algorithm for calculating the roof is quite simple, for its implementation you need to know elementary mathematical formulas from school course learning. How to calculate the number of sheets and additional elements:
- draw a sketch of the roof, indicate all dimensions;
- break the roof into separate elements in accordance with the number and geometric parameters of the slopes;
- calculate the area of each element;
- calculate the length of the ridge or ridges, valleys, gables and determine the number of meters of elements, taking into account the length of the overlap;
- determine the number of sheets of ondulin depending on the angle of inclination;
- at the rate of at least 20 pieces per sheet, buy special nails.
If during the calculations numbers with tenth values are obtained, then they need to be rounded only upwards. It is better to let a little remain in stock than to have to stop installation work due to lack of materials. During construction, it is even theoretically impossible to accurately calculate building materials, too many factors make their own adjustments. Do not try to count to a square centimeter, it will not bring any savings.
Bituminous sheets "Onduline" have high performance characteristics and are able to withstand heavy loads and climatic conditions. The price of ondulin is distinguished by its availability, and the material can serve up to 50 years. Manufacturers offer several types of this material. They have certain differences and the same performance characteristics. This article will consider the dimensions of the ondulin sheet for the roof, the average prices for the material and additional elements.
Varieties of coating "Onduline"
Today you can buy several types of ondulin. The most common type is Ondulin Smart. It is the most common and is considered practical option roofing. The material is lightweight and easy to install.
The main advantages of such a roof are resistance to strong temperature fluctuations and noiselessness during precipitation. The sheets have convenient dimensions for installation and low cost. The warranty for this roofing is 15 years. Offered in several color schemes. The cost of the material is about 250 rubles. per m².
The second option is a tile made of the same material. The peculiarity of this roofing material is that the coating has a classic look of tiles. At the same time, all the characteristics and advantages, as in the previous version. The shingles also come with a 25-year warranty and are available in several colors. Such material can be bought at a price of about 480 rubles. per sheet.
Ondulin Smart have some differences from the classic ones - this is a lock that helps to lay them faster and easier. Along the edge there are special strips that protect against water penetration, the size of the overlap has decreased, which saves on material when covering large areas.
The locks have strips that can be used as guides, helping to make the roof as flat as possible. All sheets have markings for nails. Such sheets have standard dimensions of 1.95x0.96 m. The thickness is similar to ordinary sheets - 3 mm, and the wave width is 9.5 cm. However, they have a little more weight - 6.3 kg.
Sheet mounting
The price per sheet of andulin roofing makes this material one of the most popular. Also, its advantage is fast and extremely simple installation thanks to special elements. The technology resembles the laying of a classic coating, where sheets are laid on a crate or an old carpet. The material can be used for roofs with different slopes, while the larger the angle, the smaller the pitch of the crate.
While working, you must adhere to some rules:
crate can be done from board, OSB or plywood, a solid base is made if the angle of inclination is less than 10 degrees;
styling gotta start downwind, the overlap is done on one wave, thanks to the locks, the rows are even;
Ondulin is a modern alternative to slate. It is based on cellulose impregnated with bitumen, minerals and pigments. The material is safe and environmentally friendly. And thanks to the size of the sheet, installation does not take much time. Sheets fit snugly and are customizable.
Benefits of ondulin
One of the main advantages of such coverage is its cost. You can buy ondulin for the roof, the price of which is 450-550 rubles per sheet, in different colors, which will complement the design of the house. Another significant advantage is the ease of laying the roof due to the low weight of the sheets. This is an additional savings on delivery and the ability to complete everything faster. installation work compared, for example, with slate. The material simply adapts to all sizes as a result of being very easy to cut.
The light weight of the material guarantees a minimum load on the roof system, which saves on rafters. This type of roofing material can be laid on top of the old one, so you can save on dismantling. The material is environmentally friendly and safe for people and the environment. Differs in resistance to development of a mold and a fungus thanks to special fillers. The material is distinguished by high rates of sound insulation.

Characteristics of ondulin
The cost of ondulin is due to its certain features and performance characteristics. The roofing itself is similar to ordinary slate, but includes other components that were mentioned above. This material can be used for the arrangement of roofs of buildings for various purposes, both houses and social facilities and other buildings. It is taken in due to the fact that there is no asbestos in the composition of ondulin, and therefore it is safe and environmentally friendly.
Sheets are available on the market in four colors - green, red, brown, and slate. The width of each sheet is 0.96 m, and the length is 1.95 m. It should be noted that each sheet of ondulin is 4 kg lighter than slate, its weight is slightly more than 6 kg, and its thickness is only 3 mm. But the material itself is very durable, so it can withstand fairly large loads.
The material is widely used in the construction of various facilities, industrial, commercial, residential or light structures. It is light in weight and can be mounted on old flat roof coverings. The load of the new coating is on average 3 kg per square meter.
On the domestic market, ondulin sheets produced under a French license are sold. The standard sheet has a width of 95 cm, a length of 2 m, a thickness of only 3 mm, and a wave height of 36 mm. A slight error of +/- 2 mm wave height, +/- 5 mm width and +10/-3 mm length may be allowed.
For the production of sheets, pressed cellulose fiber is used, which as a result resembles ordinary slate. It is impregnated with bitumen, resins and mineral pigments on top. Thanks to the materials used, the sheet can bend transversely and longitudinally, has a small weight with a total area of 1.9 square meters.
Sheets have 10 waves, the width of which is 95 mm. During installation, an overlap is made in one wave for horizontal laying, and for vertical laying - 10-15 cm with a slope of more than 15 degrees. When laying sheets, the usable area of each in this case is approximately 1.6 square meters. With a slight slope, the vertical overlap is 20 cm, and the sides in two waves. Given these facts, it is necessary to carry out careful calculations with a specialist so that it is not necessary to purchase additional material.

The cost of material and additional elements
You can buy an onduline roof, the price per sheet of which is profitable and competitive, made in France, Italy, Russia and some other countries. The cost of one sheet can be from 250 to 550 rubles. In some cases, a little more or less, it all depends on the manufacturer and its remoteness from our country.
Additionally, for the arrangement of the roof, you will need to purchase various additional elements. These include skates, which will cost 300-350 rubles. You will also need a cornice filler for 40-70 rubles, depending on the model, a valley and a gable element, the cost of which is approximately the same - 250-350 rubles a piece.
In addition, a special apron is purchased for tiles, its average price is 370-450 rubles per unit. Some other elements are also used, the average cost of which is 250-350 rubles. One of the most expensive components of the roof are special nails - their price is 100-200 rubles apiece. The cost of one sheet of ondulin is 350-450 rubles. Ondulin Smart is a little cheaper than 250-300 rubles. The most expensive tile is 450-500 rubles per sheet.
The price of ondulin roofing generally comes out less than other popular materials that are presented on the domestic market. And thanks to the convenient size and light weight of the sheets, the installation process is much faster than when using similar analogues. This coating has many advantages. It is very strong, durable, stable and suitable for cladding various buildings. The characteristics and versatility of the coating allows it to be used for residential and commercial buildings, the material is safe, made from environmental components.
The roofing material developed by the French company ONDULINE has been considered one of the most popular in its field for half a century. Today it is produced in many countries, and Russia is no exception.
Despite the great demand, not everyone knows what the useful area of \u200b\u200bondulin is, but meanwhile 
this information is necessary in order to make an accurate calculation of the estimate. Incorrect data often leads to a shortage, and then people are forced to buy more material. Of course, there is nothing fatal in this, but it is worth knowing that different batches differ in shade, and as a result, the risk of color mismatch increases.
This material is considered a high-quality coating and is able to reliably protect your home from rain and snow, if all the laying work has been carried out correctly. The service life is at least a quarter of a century. Moreover, the manufacturer gives a guarantee for the product for 15 years.
The cost of ondulin is about 40 percent higher than that of traditional slate. Therefore, with limited finances, it is advisable to take the latter. In addition, in the same price range, there are several options for modern roofing materials that have similar characteristics and proper quality.
Ondulin copes well with sudden changes in temperature, but at the same time softens in the heat, while in the cold it becomes quite fragile. The latter circumstance explains the ban on working with this coating in the winter.
According to the manufacturer, the material is able to withstand:
- hurricane (up to 200 kilometers per hour) wind;
- a large amount of snow (more than 300 kg per square meter of roof);
- hail;
- showers.
It also has good soundproofing properties. This makes ondulin preferable if it is planned to arrange an attic in the attic. Flexibility and lightness make it much easier to work with it - even an unprepared person can handle it alone.
Since ondulin contains exclusively natural materials, it is completely safe. At the same time, the coating is not afraid of:
- fungus;
- mold;
- acids;
- alkalis;
- oils, both synthetic and organic.
Its undoubted advantage is its rich color scheme.
A significant disadvantage of ondulin is its poor fire resistance. Already at temperatures above 230 degrees, it can ignite. And after that, it burns on its own, releasing a lot of suffocating smoke. For this reason, it is necessary to carefully weigh the pros and cons if your house is heated by stoves. The company recommends in this situation to isolate pipes from ondulin with special aprons and spark arresters.
Among other things, the coating also burns out, since the manufacturer uses natural pigmenting substances. In this case, color saturation is often lost fragmentarily, as a result, spots appear on the roof surface. In such cases, the roof is simply repainted.
Over time, bitumen may appear on its surface. This company does not consider marriage.
Sheet dimensions
Currently, three options for ondulin sheet roofing are supplied to the Russian market. They differ in:
- appearance;
- design features;
- usable area.
For example, Smart tiles have special locking systems. At the same time, DIY has fewer waves than the standard sheet. And the Compact option has a small area compared to other products.
Useful is the area of the roofing material, excluding overlaps, both end and side. Knowing this value allows you to accurately calculate the amount of ondulin for your particular roof.
It is only worth noting that the usable area of the same material may differ, depending on what is the slope angle of the roof slopes. The larger it is, the smaller overlaps need to be done.
On steep roofs, ondulin is placed on top of the previous sheet by 1 wave, while on gentle roofs - by 2. This approach is needed in order to protect the house from leaks to the maximum, because water drains quickly from a sharp roof, and from those whose angle of inclination minimal - very slow.
This rule does not apply only to Smart tiles. It is equipped with a special lock, which ensures tightness in any case. The size of the sheet mentioned above is 1.95 meters by 96 centimeters. The area, respectively, is 1.56 square meters (1.9 by 0.864 m).
Ondulin DIY has dimensions of 2 by 0.76 meters. The useful area, depending on the steepness, slope varies. So, if the angle is more than 15 degrees, then:
- longitudinal overlap - 1 wave;
- transverse - 170 mm;
- usable area - 1.22 sq. m.
More than 10 degrees and not less than 15:
- 1 wave;
- transverse overlap - 200 mm;
- area - 1.2 square meters.
The slope is gentle from 5 degrees to 10:
- two waves;
- 300 mm;
- 0.97 m
For a standard ondulin, the size of which is 760 × 1950, the usable area is calculated in the same manner.
Ondulin Compact has a length of 1 meter and a width of 76 cm. Its usable area with:
- 27 and more degrees of slope - only 57 cm2;
- from 17 to 27 - 53;
- 10-17 – 50;
- 5-10 - 40 cm.
It is also necessary to mention that the height of the ondulin wave is 3.6 centimeters. There are 10 bends in a standard sheet, each step is 9.5 centimeters.
For those who do not want to bother with calculations, it is possible to calculate the exact amount of ondulin on the official website. There is a special calculator that will also indicate the number of all necessary additional elements:
- valleys;
- nails;
- skates;
- filling seals;
- waterproofing tapes, etc.
