Ondulin sheet dimensions: standard parameters and usable area. Ondulin: sheet size and how to calculate the material Ondulin useful sheet area

One of the most popular universal roofing materials today is ondulin, corrugated sheets made from organic cellulose and treated with bitumen and special compounds, increasing strength and protecting against fading and exposure to temperature changes.

The factory dimensions of the ondulin sheet, corresponding to GOST, are 2000 mm in length and 950 mm in width, with a thickness of 3 mm and a weight of 6 kg. The permissible error is no more than 2 mm. On standard size There are 10 waves 36 mm high on the onduline.

Despite the fact that the dimensions are constant, ondulin is very technologically advanced, bends easily, and due to its light weight it can be used over old coatings.

Advantages include resistance to chemicals, rotting, good thermal insulation and noise-absorbing properties, moisture resistance and wide color scheme, allowing you to implement various design solutions.

The color of an ondulin roof is maintained throughout its entire service life. With proper installation, the operating period is up to 50 years, with a stated warranty from the manufacturer of 15 years.

Laying ondulin, as a rule, does not cause any particular difficulties, but requires certain skills and compliance with some nuances. Before starting work, you need to determine the slope and area of the roof. Calculate the amount of roofing material required and prepare additional fastening building material and special tools.

You can refuse to use insulation, but waterproofing layer required. You need to start laying ondulin from the lower layers. All roofing installation work is carried out only at positive temperatures using only special roofing nails for fastening, of which there must be at least 20 per sheet. Even though it's enough soft material, it is better to avoid strong tension on the sheets to avoid distortions.

Under the roof made of ondulin, sheathing is made of wooden slats or boards. Its thickness and type are determined based on the slope of the roof.

During installation, the linearity of the joints should be strictly observed, both horizontally and vertically. Before fastening, make sure that the sheets lie flat and only then carry out the final fastening.

Overlapping four sheets at once in one corner is not allowed, so it is recommended to start the second tier of coverage with half a sheet. The overlap between tiers should be approximately 15 cm.

And of course, don’t forget about safety rules and follow technology roofing works, taking into account the properties and characteristics of this building material. Work only in soft shoes; during fastening, place it only on the crest of the wave, and not between the waves; carefully secure it.

The style of house construction and the comfort in it depend on the choice of roofing material. Reliable roof overhead, and a well-chosen covering can not only protect from bad weather, but also give home finished appearance. Ondulin roofing is just such an option; it can transform your home and withstand harsh weather tests.

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 peculiarities of the material manufacturing technology, the color shades of different batches may vary slightly. To make the appearance of the roof aesthetically pleasing, 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 projects - residential, commercial and industrial buildings, and in 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 manufacturing technology of 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, the top layer of material is covered 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, use for laying on curved surfaces, since the material bends both longitudinally and transversely. The total area of the 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

On Russian market Ondulin, manufactured under license from a French company, usually goes on sale. The length of a standard sheet is 2000 mm, width – 950 mm, ondulin thickness is 3 mm, wave height – 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 roof covering. 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, usable area 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: sheet dimensions, usable area, width of ondulin for the roof

Dimensions of one sheet of ondulin and its technical specifications. Useful area and working size of ondulin sheets for correct calculation covered roof area.

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 of Ondulin and its additional elements are, as well as how to calculate the required quantity of this material for the roof of the house.

Measuring a sheet of ondulin

French three-millimeter roof covering with the name 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.

Ondulin - dimensions of sheet and additional elements

When choosing and purchasing such flooring As Ondulin you need to know the dimensions of its sheet.

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 light 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 enough high strength. A standard sheet can withstand pressures of more than 1800 kPa. This is enough to withstand a layer of snow during the 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 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. Installation of the first sheet is carried out end-to-end with 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 executing installation work Certain rules must be followed:

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 electric jigsaw;

Ondulin should not be stretched, as its structure may be damaged.

Ondulin: sizes, photos, price per sheet

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 3 mm.

Ondulin is a popular material for the construction and repair of roofs of various objects, both industrial and residential. Sometimes it is simply called Euroslate. Among the positive features are a wide range of colors, convenient size of ondulin sheet, and attractive appearance. The simplicity of installation work and durability of service allows the material to be used for arranging roofs and commercial buildings. This building material has been in great demand for roofing, repair and reconstruction for more than half a century.

When planning the installation of a roof, the question arises of how much material is needed. It often happens that in the middle construction process you have to buy the missing ondulin. To exclude such a situation, it is worth knowing the size of the ondulin sheet in advance. The amount of material required is calculated taking into account possible problems in construction. If you omit this simple recommendation, you may encounter the fact that ondulin of the required size or color will not be available.

Main advantages of the coating

The weight of each sheet of ondulin for the roof reaches 3 kg per square meter. This allows the coating to be laid on old roofing material, eliminating the need for classic installation. The French manufacturer guarantees the product for a period of 15 years. However, ondulin usually lasts much longer - up to 50 years.

A distinctive feature is the absence of harmful or toxic substances in the composition. Among the components, only clean and safe ones are selected that do not harm health. These include purified cellulose, which is additionally impregnated essential oils, petroleum bitumen, modifiers and natural pigments to obtain color.

The technology for producing roofing material is quite simple. The first step is to clean the cellulose from impurities and debris. After this, it is impregnated with modifiers with pigments, which make it possible to obtain the desired shade. The result is pulp, which is a moist substance. The next stage is pressing the pulp and drying it. As a result, ondulin acquires a characteristic wavy surface.

Additionally, the resulting cellulose base is impregnated with petroleum bitumen on both sides. The final stage is packaging the material in a special shrink film. Each package contains a label with the required information, including ondulin dimensions. At the same time, the useful area of ondulin reaches 1.9 square meters.

Among the advantages of sheets of roofing material, the following should also be highlighted:

Resistant to all weather conditions. The leaf can easily withstand temperatures from -40 to +80 degrees, as well as wind speeds of up to 200 kilometers per hour.
Optimal noise absorption coefficient.
Ability to withstand loads on average up to 300 kilograms per square meter.
Resistant to biological degradation, including exposure to oils, alkalis and acids.
Aesthetic appearance.
Impressive service life of ondulin.
Simplicity of installation work and availability of independent implementation.

Variety of material sizes

One of the additional advantages of the roofing material is that the size of ondulin is standardized. This eliminates many problems when purchasing and makes calculating the required quantity extremely simple. Knowing the size, it is not difficult to calculate the required number of sheets for your own roof.

It should be understood that the standard sizes of ondulin sheets are also a guarantee of quality. If you see a product in a store with significant differences in width or length, most likely you are looking at a fake. It is best to abandon such material and choose a standardized version.

The dimensions themselves are as follows:

The length of the roof sheet reaches 2000 mm. This was done specifically for the convenience of performing calculations.
The width of the material reaches 950 mm. This size is considered the most convenient for organizing a roof of any size.
The sheet thickness is 3 mm. Moreover, this indicator may have small errors both in the direction of increasing and decreasing thickness. A sheet with errors will not be considered defective.
The area of one sheet is 1.9 square meters.
The useful area of one sheet is 1.6 square meters, taking into account vertical or horizontal overlaps.
The weight of an ondulin sheet reaches 6 kilograms.
The height of the profile wave is 36 mm. Each sheet has 10 waves with a pitch of 95 mm.

The required number of sheets for the roof should be calculated taking into account the transverse and longitudinal overlap. If you omit this, the purchased quantity will most likely not be enough and there will be a need to purchase additional material.

If you plan to install a standard gable roof, which has simple form and does not have any complex architectural elements; it is worth considering the slope of the slope and the roof area. For example, the area reaches 100 square meters, and the slope of the slope is 15 degrees. In this case, you will have to purchase 8 ridge elements and 63 sheets of material.

The installation instructions for ondulin sheets are standard when compared with other roofing materials. The weight of the sheet is small, and the dimensions are standard. That is why no difficulties are foreseen. However, it is worth paying attention to useful recommendations installation Among them are the following:

Remember that the most difficult step is the choice of andulin material for the roof. Here it is important to take into account the area of the roof itself, how much the sheet weighs, how thick it is, the height of the wave, the width and length of the sheet. The calculation itself is made taking into account the overlap of the wave material. In this case, the choice will be made correctly and installation will seem like a simpler workflow.

Ondulin is a high-quality and sought-after material that will make any roof more attractive and reliable. Its price is affordable. A wide range of colors allows you to choose the shade that suits your specific home. The universal roofing covering also allows work with a curved roof due to its ability to bend. During operation, the coating easily withstands significant wind and mechanical loads and weather conditions. At the same time, the material has a low level of water absorption. This allows him without loss performance characteristics withstand about 100 “freezing and thawing” cycles.

Size of ondulin sheet for the roof: usable area, weight, overlap

Description of the advantages of the material, the size of the ondulin sheet for the roof and its usable area. Information on the weight of one sheet, overlap size and installation recommendations.

What size of ondulin sheet is used when calculating the roof?

More and more private developers prefer ondulin as a roofing material. Such a choice cannot be called a mistake; miscalculations are made later, when calculating the required amount of roofing.

Recalculation will lead to unnecessary expenses, a deficiency will lead to problems with purchasing material of the required color and size. In this article we will look in detail at what size of ondulin sheet should be used in calculations and how to eliminate the possibility of error.

What is ondulin: technical characteristics.

Ondulin is a modern roofing material that appeared on the market 50 years ago thanks to French manufacturers. The ondulin sheet has a wavy shape and is made of cellulose impregnated with bitumen. Thanks to the use of alkyd resins, the coating is highly resistant to fading and sudden temperature changes.

Ondulin is environmentally friendly, inexpensive material, with a long service life (more than 50 years). It is lightweight, which greatly simplifies the installation process. The only negative that can be noted is the flammability of cellulose. But this problem The manufacturers decided to cover the sheets with specialized compounds.

The dimensions of ondulin for almost all manufacturers are strictly standard parameters, errors are allowed, but minimal, no more than 5 mm.

Technical characteristics of the roofing covering:

Sheet length – 2 m.

Width – 95 cm.

The thickness of ondulin is 3 mm.

Profile height – 36 mm;

Number of waves – 10 pieces.

Weight of 1 sheet is about 6 kg.

The size of an ondulin sheet is the usable area.

When calculating the required number of ondulin sheets for a roof, developers often make mistakes - they do not take into account that the material is laid with overlaps. Vertical and lateral overlaps significantly reduce the useful dimensions of the ondulin sheet for the roof, and the useful area is reduced from 1.9 sq.m. to 1.6 sq.m.

If the roof has a complex shape or is multi-sloped, then the working size of the ondulin is reduced even more and will be 1.3 sq.m.

Calculation of the number of sheets for laying the roof.

This calculation is very important, but it is quite possible to perform it yourself.

Important: the roof area is calculated not by the size of the house, but by the level of the eaves overhangs.

The second stage is to determine the usable area of the sheet depending on the angle of the roof. The manufacturer of Ondulin recommends observing the following parameters:

An inclination angle of 5 to 10 degrees is the useful dimensions of an ondulin sheet, taking into account overlaps of 1.29 sq.m (vertical overlap size 30 cm + 30 cm of lateral overlap).

Tilt angle from 10 to 15 degrees – 1.54 sq.m. (overlap 20 cm + overlap 20 cm).

Tilt angle of 15 degrees or more – 1.56 sq.m. (overlap 15 cm + overlap 15 cm).

The third stage is to divide the resulting roof area by the usable area of the ondulin sheet.

The fourth stage is to add 5 to 10% of the material to the results obtained. How more difficult roof, the more square meters of material you need to purchase for stock.

Installation subtleties

Ondulin does not require complicated installation. Laying is carried out on a lathing made of wooden slats or boards. The thickness and pitch of the sheathing strictly depends on the angle of the roof:

If the roof has a small slope of up to 10 degrees, then a continuous sheathing is required (plywood and boards can be used).

Roofs with a 10-15 degree slope are assembled on lathing in increments of 45 cm.

An inclination angle of more than 15 degrees allows lathing with a maximum pitch of 60 cm.

Important: when assembling the roof, the linearity of the joints (both horizontally and vertically) must be strictly observed. Before fastening the sheet, you need to make sure that it lies evenly in relation to the others and only then secure it completely.

Ondulin roofing does not allow four sheets to overlap simultaneously in one corner. To avoid this situation, professionals advise starting the second row with half a sheet.

Taking into account the technical characteristics of the material and safety rules when installing ondulin, you can only walk on the surface in soft shoes, standing exclusively on the top of the profile (not between the waves).

Video - calculation of ondulin for a roof

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.

There is a special program for calculating 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°.

Useful area of ondulin

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

PLEASE NOTE!

It is strictly not recommended to use an electric jigsaw for cutting ondulin 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 are certain features here. 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. Circular saw gives an even, 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 many 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– a 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.
– high quality 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°).
There are 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.

Characteristics of ondulin

The manufacturing technology of 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, the top layer of material is covered 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. The total area of the 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 have a negative effect on health.

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 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 roof covering. 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.

Principles for calculating roof coverings

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 of the roofing system. Their presence and quantity affects the calculation of ondulin sheets.

The need for accurate calculations

A competent approach to calculating an ondulin roof, taking into account the dimensions of the sheet elements, will allow you to avoid problems associated with the acquisition and delivery of missing material, which not only entails additional costs for transport, 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 the 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”.

First production plant corrugated sheets opened in the suburbs of Paris in 1944, since then the brand name has not 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. The higher price per square meter of 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 they are used environmentally clean materials: 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 go well with wooden and brick facades, harmoniously complement the cladding made 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 waterproof guarantee reaches 15 years, but in reality Ondulin lasts 2-3 times longer.
Affordable price. In addition to the low cost of the material itself, savings on installation are added. 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, in lately fakes appeared on the market low quality, and with them - complaints about the deterioration of product performance. When purchasing Onduline, pay attention to the factory marking 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.

Determining the required amount of roofing covering

Dimensions of ondulin sheet and its price

The roofing material ondulin (euro slate) belongs to the category of soft roofing. Sheets of this material are made from organic fibers impregnated with bitumen at high 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 of 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

The wave height of the sheet is 36 millimeters. Also, quite recently, SMART ondulin appeared on the building materials market, 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 enough to withstand a layer of snow during the winter months, as well as the weight of several workers.

Calculation of the amount of ondulin on the roof

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.

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 mounted on 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.

Installation of sheets

The first step is to install the 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.

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 of complex shape. They are installed at the junction of two roof slopes in the 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.

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.

Endows 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 = roof S/S useful sheet(coefficient).

The formula makes sense if the calculation is made for 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 total area gable roof of your house - 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 that 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.
