It is believed that the working area of ondulin is from 1.3 sq.m with a very steep roof, when there is a need to use large overlaps of sheets on top of each other and 
layer in two waves, and up to 1.6 sq.m.
Exists special program to calculate the number of sheets. It's called ondulineroof, you can easily download it on the Internet or use ours.
In fact, you only need to know the dimensions of the roof and calculate its area. If it has a simple geometric profile, which can be divided into separate rectangles, triangles, or at least trapezoids, the area of which is in known formulas, then it becomes easier.
The roof area is found, summed up from the areas of the geometric shapes that make it up, and then you can calculate the number of ondulin sheets, dividing either the resulting value by 1.5, or by 1.3 for a very steep roof, or by 1.6 for a flat roof, up to 10°.

How much does a sheet of ondulin weigh?
The weight of an ondulin sheet is 6 kg plus or minus 300 grams.
How to cut ondulin
NOTE!
Use electric jigsaw for cutting ondulin is categorically not recommended due to the fact that it has teeth are too small and they will become clogged with cellulose.
During the installation process, ondulin often has to be cut, sometimes into small pieces, in order to lay the material around or other difficult areas of the roof. It is often necessary to cut off the excess if the overlap is excessive.
Cutting a sheet with a stationery knife
Remember: the ondulin is cut from the “facade”, that is, the front side, the top of which is laid towards the sky. And they also cut not along the wave, but along the depression between the waves.
How to cut ondulin? The cutting technique is as follows:
- An incision is made. That is, cutting begins with making a cut from the front side. Then the sheet is folded, turned over, and it is cut further.
- How to cut ondulin? For these purposes, an ordinary stationery knife. It allows for smooth cutting without leaving “crumbled” edges, everything will be clear and even.
- This is if cutting along the sheet is meant. If it is across, then there is nothing better than a classic hacksaw for wood. But there is certain features. This cutting also occurs on the front side. But you need to make high-quality markings first in order to cut exactly along the line.
- If you need to cut a lot of sheets, you can use a “circular saw,” that is, a circular saw. A circular saw gives a smooth, regular cut.
- As for cutting with a grinder, you can use it, but be careful. It is necessary to ensure that the edges of the cut do not melt, since when cutting with a grinder at high speeds, due to friction, the temperature of the material at the place of the cut from the circle increases.
CAREFULLY!
If during work The teeth of the circular saw will become clogged with fibers made of cellulose, then for cleaning you will need to make at least one cut on wood.
You should not cut ondulin in the sun. It is necessary to do this in the shade, and best of all - in a room where it is cool.
Alternative roofing coverings
An alternative to a roof made of ondulin can be a roof made of galvanized iron, corrugated sheets, galvanized iron, roofing felt, tiles and the most important material today- metal tiles.
The roof, covered with galvanized iron, looks neat and is capable of for long years protect from moisture and precipitation.
Snow does not stay on a galvanized roof, so you can use thinner rafters for a galvanized roof and save money.
- Classic roofing felt- star among roofing materials. It is easy to transport, inexpensive at all, easy to stack - it is in deserved demand. Now improved roofing felt of more modern brands has appeared, it has become even more popular. It is mechanically resistant to impacts, durable, has high elasticity - it is not for nothing that they cover the roofs of residential buildings, at least many Soviet-built houses are covered with roofing felt.
- - qualitative modern material, pressed from rolled steel. Very durable, lightweight, easy to install, impact resistant environment and durable.
- - king of the roof. Metal with tiles combines the advantages of both, eliminating their disadvantages. It looks better than just metal, and the properties are better than tiles. Provides ease of installation and durability, it is very popular among builders. Why is there a place for other materials like ondulin? The issue is the price.
- Roof tiles It can be made from baked clay (ceramic tiles), thermoplastic composite, a solution of sand and cement (cement-sand tiles) or lime and sand with heat treatment (silicate tiles). The most famous clay tiles are made from plastic clays with a low melting point (sometimes a material such as fireclay is added to it). Classic tiles are fragile and heavy. The roof underneath should have a steep slope to allow water to flow down. Modern models Can also be laid on flat roofs (10°).
- Is there some more slate, but, of course, they are no longer considering him seriously. And in European countries it is prohibited for use due to asbestos. Although our sheds can still be covered with it. The manufacturer is also important here - now they manage to make it unevenly.
Useful video
We invite you to watch a video on calculating a roof made of ondulin:
Ondulin is one of the most convenient roofing coatings for installation. The dimensions of the ondulin sheet allow the construction of a roof from this material, even alone. The use of these soft, but at the same time quite durable sheets is justified in various fields civil engineering, from private houses to small shops and office buildings. Therefore, the installation instructions for ondulin will be useful to everyone who plans to carry out roofing works.
Dimensions of ondulin sheet and its consumer properties
The production of this roofing material has been carried out since 1994. Then it was invented in France. It appeared in our country relatively recently, but it has gained well-deserved popularity. The technology for the production of euro slate, as ondulin is also called in our country, is based on the impregnation of compressed cellulose with bitumen. The sheets are made wavy, similar to the usual familiar slate.
The color of the sheets depends on the pigment added to the bitumen impregnation, as well as on its saturation. The surface of the sheets is treated with thermoresin and other mineral components. This ensures moisture resistance and strength.
Ondulin, photos of which can be found in various online stores, consists of several substances:
- Mineral fillers.
- Thermal resin with mineral pigments.
- Bitumen purified from impurities.
- Cellulose fibers.
The standard dimensions of an ondulin sheet do not differ much from the dimensions of slate sheets and are:
- Normal length – 2 m.
- The generally accepted width is 0.95 m.
- The thickness of the product is 3 mm.
- The wave has a height of 3.6 cm.
- The weight of one sheet is 6 kg.
The difference is the weight, which is significantly less, and the shallower wave height. It is the weight that is the main advantage over other roofing materials. After all, the details of the rafter system for an ondulin roof can be much thinner. Since this material can be conditionally attributed to soft type roof, its installation is very convenient. The sheets are secured to the sheathing with nails with large heads. You can cut them with a regular hacksaw or circular saw. The dimensions of the ondulin allow it to be installed alone or by two people, which greatly reduces the cost installation work. The disadvantages include: odor when heated and low fire safety class.
Ondulin installation instructions
The technology for installing this material on pitched roof strongly depends on the angle of its inclination. If it lies within the range of 5 to 10 degrees, then a continuous sheathing is made. It can be made of board with a thickness of 15 to 25 mm or multilayer plywood. Adjacent sheets are overlapped in 2 waves. Sheets from adjacent rows are overlapped by 300 mm. The top sheet is placed on the bottom until they reach the top of the slope. The standard dimensions of ondulin allow three rows of sheets to be laid on a 5-meter slope.
If the angle of inclination of the planes of the roof slopes increases to the range of 10 - 15 degrees, then the sheathing can be made not continuous. An interval of 45 cm is taken along the axes. That is, this is the distance between the upper edges of two adjacent boards. The overlap at the ends is 200 mm, and at the sides - 1 wave. Angles of inclination greater than 15 degrees allow the use of lathing with an axial interval of 60 cm, an overlap of 170 mm at the ends and 1 wave on the side.
Each sheathing board is nailed parallel to the eaves board. To do this, a reference “interval” is made from bars, which is used to mark the attachment point for each subsequent sheathing board. To accurately mark wavy sheets, you need to take a small piece of ondulin with a straight edge and draw along it with a colored pencil. This will allow you to draw precise lines.
Step-by-step algorithm for installing an ondulin roof
Further instructions for installing ondulin are as follows:
- We determine the edge of the roof that is on the other side of the prevailing winds in your area.
- We begin laying the first row from the selected edge of the roof. In this case, you need to pay special attention to the first sheet. Its lower cut should be absolutely parallel to the cornice. First attach it to one nail in order to adjust the position if necessary.
- A rope is pulled along the entire length of the batten board. This is necessary so as not to miss the nail past the board. When the 3 sheets are laid down and you are sure they are parallel to the cornice board, nail them down. About 20 nails need to be driven into each sheet. At the ends of the sheets, nails are driven into each wave, in the middle it is possible through one, and the side overlap is attached on both sides.
- After initial row securely nailed, you can start laying the second one. Special attention should be given to piercing the overlap with nails. The sheets in these places should not have any play. All subsequent rows of ondulin are laid in the same way. When moving on sheets with your feet, you should only step in places where there are sheathing boards and only in soft shoes, or better yet, barefoot, if the weather permits.
- When the sheets on both roof slopes are completely secured, proceed with the installation of the ridge element. It is made of the same material, so it is very pliable. They begin to fasten it from the same side from which they began to lay the sheets. The overlap is made at least 125 mm. Nail the ridge into each wave of all sheets on both sides.
- After this, the valleys, if any, are designed, which are produced and sold along with the sheets. A special sheathing is made for their installation.
- Closing the ends of the roof is done with tongue or ridge ondulin, which begins to be nailed from below. It is fastened both from above and from the side. If there are various elements on the roof or vertical walls, then the joints with them can be formed using the same valley. In this case, you need to organize in this place good waterproofing so that ondulin does not leak. Reviews from owners are sometimes negative due to the fact that this point was not given enough attention. The leak always started in such places.
- If the roof is complex or hipped, then you will have to cut the ondulin at an angle. The dimensions of the sheet are such that this is not difficult to do. The lower edge of the first sheet is aligned with the beginning of the slope. In this case, the cut of the inclined ridge will be the line along which it is necessary to cut this sheet. We perform the same manipulation with all subsequent sheets above. The corner joint is closed with a ridge element and nailed into each wave.
What other additional parts can be used when installing an ondulin roof?
Since this material tends to emit a strong odor when heated under sun rays, then the roof and attic space need regular ventilation, especially in the hot season. For this purpose, manufacturers produce various roof fans that are combined with ondulin. They are fastened anywhere on the roof plane with nails in each wave. At the same time, the joints are well waterproofed.
Roof windows are used to illuminate the attic space. When installing them, it is necessary that top sheet lay overlapping on the base of this element. The windows are also fastened with ondulin nails. Reviews from owners indicate that the use of such windows is completely justified, since in addition to lighting, they provide the opportunity to go out onto the roof if necessary.
One more useful element is a cornice filler. This is a gasket that is placed under the ondulin at the level of the eaves or under the ridge element. It is needed to prevent birds from entering the attic.
Ondulin roofs, photos of which can often be found when viewing finishing options, allow you to save not only on the cost of the material itself, but also on the details of the rafter system. In addition, no additional people are needed for installation. After watching a video on how to cover a roof with ondulin with your own hands, you can handle everything yourself.
Sheet material developed by the French company ONDULINE has been one of the popular materials for roofing for more than half a century. Today, ondulin is produced in many countries of the world, including Russia. Due to the nature of the material manufacturing technology, the color shades of different batches may vary slightly. To ensure an aesthetic appearance of the roof, 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 construction capital facilities– residential, commercial and industrial buildings, during the construction of light structures – pavilions, kiosks, canopies, gazebos. Due to its light weight, this sheet material is ideal for repairing old roofs: it can be mounted on top of flat, old roof coverings without fear of excess load on the foundation of the structure. The approximate load of the new flooring will be about 3 kg per 1 m2.
The technology for manufacturing the material is quite simple: cellulose fiber is pressed into corrugated sheets, reminiscent of traditional slate in shape. Then the base is impregnated with bitumen, upper layer The material is coated with a layer of mineral pigment and curable resins. The small thickness of ondulin makes it easy to install - the sheets are easy to lift onto the roof, cut, and use for laying on curved surfaces, since the material bends both in the longitudinal and transverse directions. total area standard sheet is 1.9 m2.
The advantages of ondulin include:
- long service life (warranty - 15 years, actual service life - 50 years);
- attractive appearance;
- resistance to moisture and atmospheric influences (squally winds up to 200 km/h, temperatures from -40 to +80°C);
- high noise absorption coefficient;
- simple installation;
- resistance to biological destruction, acids, alkalis, oils;
- ability to withstand loads up to 300 kg/m2.
Ondulin, unlike standard slate, does not contain harmful substances and does not provide negative influence to your health.
Ondulin sizes
Ondulin, manufactured under license from a French company, is usually sold on the Russian market. The length of a standard sheet is 2000 mm, width – 950 mm, ondulin thickness is 3 mm, wave height – 36 mm. The permissible error may 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 roofing. 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 a roof whose slope slope exceeds 15 degrees should be at least 100–150 mm. As a result, the useful area of one sheet element reaches 1.60–1.64 m2.
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 usable area of the sheet material, so that in the future you do not have to purchase additional products from another batch.
Principles for calculating roof coverings
The easiest to calculate are gable roofs with an inclination angle of 15 degrees, each slope of which is a rectangle, and the overlap parameters are standard. In this case, it is necessary to calculate the roof area and divide it by the usable area of one sheet of ondulin - 1.6 m2.
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 roof materials, you should also take into account the presence of windows in the roof plane, the use of elements such as a valley, ridge, covering aprons, eaves gutter, roof ventilation elements and other components 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 m2 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 calculating ondulin roofing, taking into account dimensions sheet elements will allow you to avoid problems associated with the acquisition and delivery of missing material, which not only entails additional transportation 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.

Ondulin roofing price per sheet dimensions and photos
Roofing Ondulin is in stable demand in more than 100 countries around the world. The reasons for this popularity are: affordable price and universal sheet sizes.
Ondulin “SMART” - reliable waterproofing and quick installation
Price per sheet: from 392 rubles.
On forums on the Internet there are often discussions of “andulin roofing” or “andulin”. This spelling is not entirely correct: the name comes from the French word “Onduline”, accordingly, in Russian “ondulin” also begins with the letter “o”.
The first plant for the production of corrugated sheets opened in the suburbs of Paris in 1944, since then the name trademark hasn't changed.
Ondulin SMART is equipped with a special Smart Lock hydraulic lock made of two strips extruded along the edges of the sheet. Guide grooves regulate the end overlap and form tight joints. Factory marked mounting points make installation easy.
Ondulin “DIY” - resistance to stress and easy transportation
Price per sheet: from 412 rubles.
DIY corrugated sheets fall under the DIY category. The small width simplifies transportation - the material easily fits in the trunk of a car. Higher price square meter roofing (compared to Ondulin Smart) is explained by the increased number of overlaps. The finished coating is more durable and can withstand high wind and snow loads. Ondulin DIY is recommended for areas with harsh climates.
Ondulin "Tile" - long-term operation and bright color
Price per sheet: from 467 rubles.
By appearance Ondulin tiles resemble classic analogues made of ceramics and metal. Graduated tinting of individual areas creates a volume effect, and innovative technology dyeing ensures color fastness.
The price of Ondulin does not include the cost of branded nails. They are purchased separately, at the rate of 18 fasteners per sheet. When calculating the number of sheets, it is necessary to take into account the roof slope angle: the smaller it is, the more overlaps will have to be made. The approximate usable area of Ondulin is 1.56 m2 at a slope of more than 15 degrees, 1.52 m2 at 10-15 degrees and 1.29 m2 on a flat roof.
Roofing solutions from Ondulin
In appearance, ondulin roofing resembles slate roof. The materials are united by a wavy profile, color scheme and almost identical size, but that’s where the similarities end. For the production of Ondulin, environmentally friendly materials are used: cellulose fibers, bitumen, polymer resin impregnations, mineral dyes and natural pigments. The brand's line includes three types of roofing sheets - SMART, DIY and Tile. They differ in size, price and color range.
Ondulin roof colors
The tint range of DIY and Ondulin tiles is presented in red, brown and green. There is another option for Smart sheets - black (slate).
Green tiles Ondulin
Brown tile Ondulin
Red tile Ondulin
Ondulin's colors are distinguished by restraint and unobtrusiveness. Matte roofing sheets combine well with wood and brick facades, harmoniously complement the sheathing of plastic and metal siding. Most often, Ondulin is matched to the main color of the house, but there are more original ways- play on contrast and combination of several shades. The unified profile of the sheets allows you to combine them in any variations.
Advantages of roofing coating Ondulin
- Long service life. The waterproofness guarantee reaches 15 years, but in reality Ondulin lasts 2-3 times longer.
- Affordable price. TO low cost the material itself adds savings on installation. You can handle laying corrugated sheets yourself.
- Light weight. Another saving point is that to transport Ondulin you do not need to hire transport and pay for the services of loaders. Sheets are placed in passenger car and weigh no more than 6.3 kg each.
- Chemical and biological stability. The material is not afraid of exposure to alkalis and acids, and fungus does not appear on it.
- High-quality waterproofing. Smart Lock technology ensures no leaks; branded nail heads provide additional protection.
- Silence and comfort. Unlike metal tiles, Ondulin hides the sounds of rain and snowfall. In the attics you can’t hear the sound of rain, the steps of birds on the roof and the sound of falling leaves.
- Ecological cleanliness. When heated, the roof does not emit harmful fumes.
Unfortunately, low-quality fakes have recently appeared on the market, and with them complaints about deterioration performance characteristics products. When purchasing Onduline, pay attention to the factory markings of the sheets - each of them is marked with the name of the Onduline brand, the code of the country of origin, the batch number and the date of manufacture. Avoid establishments selling “andulin roofing” and contact official dealers.

Dimensions of Ondulin sheet and its overall characteristics
No one goes for building materials at random - this is, at least, unreasonable. Before purchasing, we always calculate how much of something we will need. So, for example, when choosing ondulin for a roof, the dimensions of the sheet should be clarified in advance. After all, having taken an insufficient amount of material, you can, when purchasing more, be very upset when you see that the shade from the new batch is not at all the same, well, but you also don’t want to overpay. Therefore, in this article we propose to understand what sizes Ondulin and its additional elements are, as well as how to calculate the required amount of this material for the roof of a house.
Measuring a sheet of ondulin
The French three-millimeter roofing covering called ondulin (or euroslate) is based on organic cellulose fibers. For strength and color preservation, the material is impregnated with bitumen with special additives.
During the manufacturing process of standard ten-wave sheets, the following deviations are allowed:
- across sheet width: from -5 to +5 millimeters;
- along the length of the sheet: from -3 to +10 millimeters;
- by wave height: from -2 to +2 millimeters.
And now the parameters of the Euroslate sheet themselves:
- Sheet width – 0.95 meters;
- sheet length – 2 meters;
- wave crest height – 3.6 centimeters
- sheet thickness - 0.3 centimeters;
- leaf weight – 6 kilograms.
During installation you will also need fasteners and accessories. In addition to specialty nails, eaves, valleys, gables, gutters and eaves cores, windows, and roof vents will be needed. You should definitely take them all into account.
Dimensions of additional Ondulin elements
Determining the required amount of roofing covering
Typically, these calculations are undertaken by the company that will install the ondulin roof. Usually she sells it. However, if you want to cover the roof with Euro-slate yourself, then to calculate its amount, the size of ondulin and school knowledge in mathematics will be quite enough. You just need to imagine the entire surface of the roof in the form of simple geometric shapes - triangles, rectangles, squares. Having easily calculated the area of each, add them all up - this is the roof area.
And now the most important thing is to avoid making the main mistake of choosing “dirty” sizes instead of “clean” ones. Otherwise, without taking into account the margin required to overlap the ondulin sheets. It is necessary, otherwise the quality of the roof will suffer. Therefore, simply multiplying the length and width, giving a sheet area of 1.92 square meters, is not suitable for determining material consumption. After all, about 0.3 square meters from this sheet will be spent on overlap.
Now more accurate calculations. When the roof is laid, the ondulin sheets overlap not only in the longitudinal, but also in the transverse direction. The overlap in length will be from 10 to 15 centimeters, and in width - one wave (9.6 centimeters). We get the “clean” dimensions:
With these dimensions of the ondulin sheet, its useful area will be smaller - from 1.6 to 1.64 square meters. And one more thing: do not forget that the roof will have to be trimmed along the edge, and 10 percent more material will be needed. Base yourself on these numbers when purchasing roofing.
Dimensions of ondulin sheet and its price
Roofing material ondulin (euro slate) belongs to the category soft roof. Sheets of this material are made from organic fibers impregnated with bitumen at high blood pressure and temperature.
The outer side of ondulin is coated with dyes and special resin.
Thanks to this, the material acquires an attractive appearance and additional strength.
Benefits of ondulin
This roofing material has the following advantages:
- good sound absorption;
- high strength;
- simplicity and ease of installation;
- does not contain asbestos;
- ease of care;
- low price;
- condensation is almost completely absent.
How much does one sheet weigh?
One of the main advantages of ondulin is its low weight. One sheet of ondulin, having 10 waves, weighs 6.5 kg. For comparison, one square meter ceramic tiles is approximately 40 kg. Due to this, the process of laying the material is greatly simplified. Even one worker without a partner can lift the sheets and install them. Ondulin sheets are light in weight and do not create significant pressure on the roof frame. Therefore, it does not need to be strengthened.
Ondulin sheet dimensions
A standard size sheet of ondulin has a length of 200 centimeters and a width of 96 centimeters. The thickness of the roofing material is three millimeters. However, ondulin is not inferior in its rigidity to metal tiles.
photo of ondulin sheets
The wave height of the sheet is 36 millimeters. Also very recently on the market building materials Ondulin SMART appeared, the length of which is five centimeters less.
Ondulin can withstand loads of up to 960 kg/s per 1 sq. m of roofing. Most often in such cases, only the rafter system and roof sheathing are destroyed.
Material strength
Wave ondulin has fairly high strength. A standard sheet can withstand pressures of more than 1800 kPa. This is quite enough to withstand a layer of snow in winter months, as well as the weight of several workers.
Heat resistance of the material
According to the manufacturers, Euro slate does not lose its shape and characteristics at temperatures up to 110 degrees Celsius. But not all consumers agree with this. Many people claim that the edges of the roofing material melt in extreme heat. This also produces a special smell.
Sound insulation of Euro slate
The ondulin coating absorbs noise quite well, the value of which does not exceed 40 dB. When it rains, the noise will not be heard. It should be noted that the parameters of this material may vary depending on the country of origin.
Price per sheet
The cost of one roofing sheet is 200-400 rubles. Ridge elements cost 230 rubles, valleys - approximately 200 rubles, gable profile - from 230 to 250 rubles, cornice filler - from 30 to 50 rubles. The cost of the Ondufshesh lining carpet is in the range from 800 to 900 rubles.
Calculation of the amount of ondulin on the roof
The main mistake when calculating the amount of ondulin per roof is taking into account the actual area of the roofing sheets instead of the useful one. The actual area of the ondulin sheet is 1.9 square meters. m. However, the useful area of the sheet when the roof is tilted from 15 degrees is 1.6 sq.m. This difference arises due to the fact that ondulin is laid with an overlap in width and length.
Calculation of ondulin for a roof of complex shape
If the roof has a complex configuration, the calculation of the material is carried out differently. To do this, you need to divide the roofing surface into sections, calculate their areas separately, and then add up the areas.
The resulting value will be the total roof area. Next, you need to calculate the number of sheets using the above formula. It is better to buy roofing material with a small margin. The number of nails per sheet of ondulin for the roof is 20 pieces, per gable - 5 pieces, per roof ridge - 20 pieces.
Installation features
When choosing the pitch of the sheathing for ondulin, you should focus on the angle of inclination of the roof. If the slope does not exceed 10 degrees, then the ondulin sheets should be attached to a continuous sheathing made of OSB boards or plywood.
The overlap in width is 2 waves, and in length - 30 centimeters. If the roof slope is 10-15 degrees, then the sheathing is made from boards or timber.
The sheathing pitch should be from 40 to 50 centimeters. The overlap in width is made in one wave, and in length - 20 centimeters. If the slope of the roof slopes is more than 15 degrees, then the sheathing pitch should be 60 centimeters. The overlap of roofing sheets is made in one wave in width and 17 centimeters in length.
Installation of sheets
First of all, install cornice strip. Next, the first row of ondulin sheets is laid along the eaves overhang. The installation of the first sheet is carried out flush with the gable overhang. Also, the sheet must extend beyond the roof eaves by at least 5 cm.
Each sheet of ondulin should be secured with 20 nails. First of all, fix the corners of the sheet. Next, fix the lower edge of the ondulin in each wave. The top and middle of the roofing sheet are fastened in a checkerboard pattern through one wave.
After laying the first row with the required overlap, proceed to install the second strip of material in the same way. It should be noted that even rows (second, fourth, sixth, etc.) must be started from half a sheet.
Installation of the valley and ridge element
At the next stage, the roof ridge is installed. It is mounted at the junction of two roof slopes. The ridge element is fastened using nails (in each wave of Euro slate).
Valleys are an element of roofs complex shape. They are installed at the junction of two roof slopes in inner corner. Before installing the valley, it is necessary to lay a waterproofing carpet. Laying the valley begins from bottom to top. In this case, it is necessary to maintain an overlap of 10-15 centimeters between the elements. The amount of overlap should be selected depending on the slope of the roof slopes.
To fix the valleys, I use special clamps nailed to the roof sheathing. It is not recommended to nail valleys through and through.
Ondulin sheets are laid overlapping on the grooves and cut off. This is done in such a way that the distance from the center of the valley to the edges is 5 cm on both sides. Filler is placed in advance under the ondulin sheets. Euro slate should be fixed in each wave.
When performing installation work, certain rules must be observed:
- laying of the material should be carried out at temperatures from -5 to +30 degrees Celsius;
- it is necessary to control the horizontal installation of roofing sheets;
- to cut ondulin you should use a hacksaw or an electric jigsaw;
- Ondulin should not be stretched, as its structure may be damaged.
Ondulin: sheet sizes and other characteristics
The roofing material ondulin (Euro slate) is “gaining momentum” in Russia and is increasingly being used on roofs of any type with a slope angle of 5 degrees or more.
It is easy to install, transport and operate, and has unique technical characteristics that you need to become familiar with before installation.
Sheet sizes
The standard dimensions of an ondulin sheet (L*W) are 2 meters by 96 centimeters.
The thickness of the material is 3 millimeters, but its rigidity is not inferior to, for example, metal tiles.
The height of the wave is 3 centimeters 6 millimeters. Not long ago, SMART ondulin appeared on sale.
Its length is 5 centimeters shorter.
The weight of an ondulin sheet with ten waves is 6.5 kilograms, its installation is greatly simplified.
One person can lift Euro-slate onto the roof and work with it there, without the help of a partner.
A roof covered with ondulin will not exert strong pressure on rafter system, so there is no need to strengthen it.
The strength of a standard sheet of roofing material is more than 1800 kilopascals.
This is enough to withstand significant snow loads and the weight of several people.
Euroslate can withstand loads of up to 960 kg/s per 1 square meter of coverage.
Often, only the sheathing and rafter system are destroyed.
Thermal resistance
However, not all consumers agree with them. You can often hear complaints that the edges of the material begin to melt in extreme heat, and a specific smell arises.
Noise insulation
Euroslate absorbs noise well, up to forty decibels.
The sound of rain on the roof will not be heard.
Material characteristics may vary depending on the country in which it is produced.
Check them out in the table.
The cost of roofing material ranges from 200 to 400 rubles.
Valleys cost approximately 200 rubles, ridge elements - 230 rubles, cornice filler - 30-50 rubles, gable profile - 230-250 rubles, underlay carpet onduflesh - 800-900 rubles.
Calculation of ondulin on the roof
The main mistake that is made when calculating the material for a roof is taking into account the actual area of the sheets, and not the useful one.
The actual area covered by one sheet is 1.9 meters (2m x 0.95m).
But the useful value for a slope slope of 15 degrees will be 1.6 meters. This scatter occurs because the ondulin is mounted with an overlap in length and width.
To determine the number of sheets, use the formula: K = S roof/S useful sheet (coefficient).
The formula makes sense if the calculation is made for a gable roof, on which there are no complex geometric transitions and junctions.
The useful area of the sheet varies depending on the slope of the slopes.
If the slope is in the range from 5 to 10 degrees, then the coefficient is 1.29 (m2).
With a slope of 10 to 15 degrees, it will already be equal to 1.54.
Calculation example
Let's imagine that the total area of the gable roof of your house is 100 square meters.
The useful area that one sheet will cover with a slope slope of 15 degrees is 1.6 meters.
Now let's divide 100 by 1.6. We get the number 62.5. Round it up to a whole number. As a result, you need to purchase 63 sheets to cover the entire roof.
If the slopes were located at an angle of 10 to 15 degrees, then the value of 100 would have to be divided by a coefficient of 1.54, etc.
Roofs of complex shapes
When the roof has many slopes connecting to each other, other architectural excesses, the calculation must be carried out differently.
One option is this: the entire roof surface must be divided into equal plots, then sum their area to get the total.
Installation features
The pitch of the sheathing for Euro slate depends on the slope of the roof.
So, with a slope slope of up to 10 degrees, a continuous sheathing of plywood or OSB board must be made under the roofing material.
The sheets are laid with an overlap in length - 0.3 meters, in width - 2 waves.
When the roof slope is from 10 to 15 degrees, timber or boards are used for sheathing, which are mounted at intervals of 40-50 centimeters.
The overlap in length is 0.2 meters, in width – 1 wave.
When the slope of the roof slopes is over 15 degrees, the sheathing is installed in increments of 60 centimeters with an overlap of 17 centimeters in length and 1 wave in width.
Laying order of sheets
First, the cornice strip is installed.
Then the first row of sheets is installed along the eaves overhang.
Laying begins on the side of the roof opposite to the prevailing winds.
If the wind blows more often from the left, then installation is carried out from the right.
The first sheet is laid flush with the gable overhang, and its “exit” beyond the cornice must be at least 5 centimeters.
To fasten one sheet you need 20 nails.
First, it is fixed at the corners, then its lower edge is attached to each wave.
The center and top of the sheet are “sewn” through the wave in a checkerboard pattern.
The photo clearly shows the process.
After all the sheets of the first row are laid with the necessary overlap, lay the second strip in the same way.
The only condition is that the first sheet must be half.
The process is repeated in the fourth, sixth row and so on.
Installation of ridge and valleys
The next stage is the installation of the ridge element.
The ridge is placed at the junction of two slopes and fixed with nails into each wave of ondulin.
Valleys (valleys) – element complex roofs. They are mounted at the junction of two slopes in the inner corner.
A waterproofing carpet is first placed under them. Laying begins from the bottom up.
The overlap of the elements with each other is 10-15 centimeters, depending on the slope of the slopes.
The grooves are fixed using special clamps, which are nailed to the sheathing.
Sheets of ondulin are laid overlapping the grooves and cut off so that the distance from the edges to the center of the valley is 5 centimeters on both sides.
Filler is pre-laid under the sheets. Ondulin is nailed into every wave.
A few tips to make your work easier
When installing ondulin, observe the following rules:
- Work is carried out at temperatures from -5 ° to +30 °;
- Always check that the sheets are stacked horizontally;
- Cut the sheets with a knife, hacksaw or electric jigsaw;
- Do not stretch ondulin so as not to damage the structure of the material.
Advantages of using ondulin
Ondulin has the following advantages:
- High sound absorption;
- Strength is greater than that of metal tiles and corrugated sheets;
- Ease and simplicity of installation;
- Ease of care;
- No asbestos in the composition;
- Virtually no condensation;
- Affordable price.
It is these parameters that attract the attention of numerous consumers.
Ondulin: roof calculation and dimensions, price per sheet
Roofing material ondulin (Euro slate): characteristics, sheet size and prices - installation features and order of laying sheets.
Ondulin, the dimensions of which are important for the master, is considered one of the most popular materials among those intended for roofing work. The coating has been known on the building materials market for more than 50 years. In order for you to have the opportunity to implement correct calculations By required quantity materials, you need to know the dimensions of the sheet.
Canvas dimensions
Ondulin, the dimensions of which may differ slightly from those prescribed by GOST, has a standard length of 200 mm. As for the width, this parameter is 950 millimeters, the sheet has a thickness of 3 millimeters, while the wave height is equivalent to 36 millimeters. The latter indicator can vary up or down by 2 millimeters. One canvas weighs 6 kg. As for the dimensions mentioned above, the length of the sheet may be 10 millimeters longer, while in the downward direction this figure cannot decrease by more than 3 millimeters. The width of the material can vary in both directions by 5 millimeters.
Specifications
Ondulin, the dimensions of which were mentioned above, lasts, according to the manufacturer’s warranty, for about 50 years. You can count on complete waterproofness for 15 years, but these figures vary depending on the correct installation and compliance with production technology. The material can be used at a fairly wide range of temperatures, which vary from -40 to +80 degrees. One square meter of coating can withstand a load of up to 300 kilograms. Squally winds of 200 kilometers per hour are not dangerous for such covering material. After completing the roof installation work, you can count on the system to absorb noise created by precipitation up to 40 decibels, this applies to rain and hail. The canvases perfectly withstand the effects of oils, fungi, acids, alkalis, and also cope excellently with mechanical stress.
Characteristics of ondulin by manufacturing country
Ondulin, the dimensions of which should interest the master who intends to use this material, may have different dimensions depending on the country of origin. For example, in France this material is produced in a length of 2 meters. This figure is true for Belgium, the USA and Switzerland. While the width varies, in France this material is produced with a width of 0.95 meters. In Switzerland, canvases according to this parameter vary from 0.87 to 1.06 m. In Belgium, canvases have a width of 0.92 meters, while in the USA this figure is 1.22 meters. The total leaf area in the first country mentioned above is 1.9 square meters, while in Switzerland these figures vary from 1.74 to 2.12 square meters. In Belgium and the USA the total leaf area is 1.84 meters and 2.44 meters respectively.
Ondulin cost
Ondulin, the sheet sizes of which you can choose taking into account the dimensions of the roof, may have different prices. Sometimes it is precisely how much money the consumer has to spend that is decisive when making a choice. Price may vary depending on color and quality characteristics. Having visited the store, you will see that for one sheet of ondulin you will have to pay from 400 to 500 rubles.
Material calculation
Ondulin, the sheet dimensions of which you already know, must be purchased taking into account calculations made in advance. It is important to take into account not only the dimensions of the canvas, but also the gaps that will be used for vertical and lateral overlaps. The area of one sheet is 1.9 square meters, this figure is calculated by multiplying the width by the length, that is, 2 must be multiplied by 0.95. If we take into account the overlap, the useful sheet area is 1.6 square meters. The dimensions of the ondulin for the roof must be taken into account in the calculations. Thus, if there is a need to equip a roof whose area is 100 square meters, and its slope does not exceed 15 degrees, then 63 sheets will be required. This figure can be calculated by division total area to the usable area of the canvas. However, such calculations can be taken as basic only if it is necessary to equip a simple gable roof, which is devoid of additional architectural elements. Otherwise, it will be necessary to use knowledge of geometry, which will be useful for determining the roof area by projection.
The dimensions of the ondulin for the roof will also come in handy in this case. However, initially it is necessary to divide the plane into correct geometric figures like squares, triangles and rectangles. Then the area of each individual element is determined, after which the master must take into account the angle of inclination of the roof; the useful area of the material will depend on the angle of the slope and can vary between 1.3-1.6 square meters. Then all the values must be added. If the projection of the roof is a rectangle, and the angle of inclination is equivalent to 30 degrees, then the surface area is equal to the product of the cosine of the angle and the area of the rectangle.
Dimensions of additional elements
After becoming famous usable size ondulin, you can ask what dimensions the additional elements have. They will certainly be used when arranging the roof. The ridge element has a length and useful length that are 100 and 850 millimeters, respectively. The thickness of this component is 3 millimeters. As for the valley, the above parameters remain the same, but the gable element has dimensions equal to 1100x950 millimeters.
Conclusion
When making calculations, it is important to take the working size of the ondulin; this is the only way to purchase the amount of materials that will be needed for the work. However, it is important to add 10 percent to the results obtained, which will be spent on cutting and possible defects. By choosing this modern roofing material, you have the opportunity to create a roof that will be durable, reliable and resistant to external negative factors. The coating is not too expensive compared to analogues on the modern market.
Ondulin, or Euroslate, is one of the most reliable roofing materials. Let's take a closer look at Euro slate - what it is, what are the advantages of this material. When carrying out calculations, you will need to know the standard size of ondulin: this will make it possible to avoid shortages or surpluses during roofing.
Features of ondulin manufacturing
Let's find out what ondulin consists of, what materials are used in production. Ondulin sheets got their name from the French company Onduline, which owns a patent for these products. Ondulin material consists exclusively of safe and environmentally friendly components, differing favorably in this respect from traditional asbestos-cement slate.
Pure cellulose is used to make the material: petroleum bitumen and ether resins are used to impregnate it. Not so long ago, the Italian-French development “onduville” appeared. Having a composition similar to ondulin, this new material imitates ceramic tiles.
The following operations are used for the production of ondulin:
- Pulp cleaning. Garbage and impurities are removed from its composition. Then the substance is soaked in water with pigments and modifiers diluted in it. The resulting raw material is called “pulp”.
- Pulp processing. The technical characteristics of ondulin provide for processing on a special conveyor, where the material is pressed to a thickness of 3 mm. Having dried and hardened, the pulp acquires a specific waviness.
- Bitumen impregnation. A cellulose base with an area of 1.9 m2 is impregnated with petroleum bitumen.
- Stacking finished material . Shrink film, equipped with a label and accompanying information, is used as packaging.
Sheet size including overlap - useful width
It is very convenient that ondulin is always available in standard sizes. If deviations in the width or length of corrugated sheets are detected, we can conclude that most likely we're talking about about forgery of interrogative quality. Having information on the useful size of an ondulin sheet in hand, it is quite simple to calculate the final amount of coating.
Standard size of ondulin sheet:
- The working width of the ondulin is 950 mm. A very convenient size for decorating small and medium-sized roofs.
- Length – 2000 mm. The round number makes material calculation very simple.
- Thickness – 3 mm. Small deviations in this parameter are allowed.
- The height of the profile wave is 36 mm.
- The weight of one sheet is 6 kg. One square meter – 4 kg.
- Sheet area – 1.9 m2.
- The useful area of ondulin smart is 1.6 m2. In this case, vertical and horizontal overlaps are taken into account.
Armed with information about the total area of the roof slopes, counting the number of ondulin sheets will not require significant effort. All you need to do is divide the roof area by the usable area of one sheet (1.6). To compensate for circumcision, 15% is added to the amount received. Also, one should not forget about adjusting the size of the ondulin sheet taking into account the overlap: this is affected by the slope angle of the slopes. In this case, the useful width of the ondulin will differ from the working one. When calculating the useful width of an ondulin sheet, the size of the side overlap is subtracted from the standard indicator.
Strengths of ondulin
Initially, the function of ondulin sheets was reduced solely to the implementation quick repair and sealing leaks on slate, tile and metal roofs. In the course of application, practice has shown that Euro slate is quite suitable as an independent roofing material.
The following qualities contributed to this:
- Light weight. Without exaggeration, we can say that ondulin is the most lightweight material for the roof. This allows it to be laid directly on old slate or profiled sheets without dismantling.
- Duration of service. Ondulin roofing can safely withstand up to 100 frosts and defrosts, which allows the manufacturer to provide a 25-year warranty. As practice shows, Euro slate lasts at least 50 years.
- Good strength. The presence of a wavy profile allows the material to have a load-bearing capacity of 650 kg/m2. It is not afraid of snow loads up to 300 kg/m2.
- Hydrophobicity. Ondulin does not allow water to pass through and almost does not absorb water, which ensures reliable protection truss structure from getting wet.
- Soundproofing. The surface of Euroslate has noise-absorbing characteristics. On such a roof, rain, hail or strong winds are almost inaudible.
When choosing ondulin as a roofing covering, it is important to take into account the fact that this material is flammable. The manufacturer does not recommend exceeding temperature regime at + 110 degrees, otherwise the sheets will begin to deform. Based on this, Euro slate should not be used in bathhouses, gazebos with barbecues, homes with fireplaces and solid fuel stoves.
