The roofing material developed by the French company ONDULINE has been considered one of the most popular in its field for half a century. Today it is produced in many countries, and Russia is no exception.

Despite its great demand, not everyone knows what the usable area of ​​ondulin is, and yet this information is necessary in order to accurately calculate the estimate. Incorrect data often leads to shortages, and then people are forced to buy more material. Of course, there is nothing fatal in this, but it is worth knowing that different batches differ in shade, and as a result, the risk of color mismatch increases.

What you need to know about ondulin

This material is considered a high-quality coating and can reliably protect your home from rain and snow if all installation work was carried out correctly. The service life is at least a quarter of a century. Moreover, the manufacturer gives a 15-year warranty on the product.

The cost of ondulin is approximately 40 percent higher than that of traditional slate. Therefore, if finances are limited, it is advisable to take the latter. In addition, in the same price range there are several options for modern roofing materials that have similar characteristics and proper quality.

Ondulin copes well with sudden temperature changes, but at the same time it softens in the heat, while in the cold it becomes quite fragile. The latter circumstance explains the ban on working with this coating in winter.

According to the manufacturer, the material can withstand:

• hurricane (up to 200 kilometers per hour) wind;
• large volume of snow (more than 300 kg per square meter of roof);
• hail;
• showers.

It also has good noise insulation properties. This makes ondulin preferable if you plan to build an attic in the attic. Flexibility and lightness make working with it much easier - even an untrained person can handle it alone.

Since ondulin contains only natural materials, it is completely safe.

Its undoubted advantage is its rich range of colors.

A significant disadvantage of ondulin is its poor fire resistance. Already at temperatures above 230 degrees it can ignite. Moreover, after this it burns on its own, emitting a lot of suffocating smoke. For this reason, it is necessary to carefully weigh the pros and cons if your home is heated by stoves. In this situation, the company recommends insulating pipes from ondulin with special aprons and spark arresters.

Among other things, the coating also fades, since the manufacturer uses natural pigmenting substances. In this case, color saturation is often lost in fragments, resulting in spots appearing on the surface of the roof. In such cases, the roof is simply repainted.

Over time, bitumen may appear on its surface. The company does not consider this a defect.

Sheet sizes

Currently, three options for sheet metal are supplied to the Russian market. roofing covering ondulin. They differ in:

• appearance;
• design features;
• usable area.

For example, Smart tiles have special locking systems. At the same time, DIY has fewer waves than a standard sheet. And the Compact version has a small area compared to other products.

Area is called useful roofing material excluding overlaps, both end and side. Knowing this value allows you to most accurately calculate the amount of ondulin for your particular roof.

It is only worth noting that the usable area of ​​the same material may differ, depending on the slope angle of the roof slopes. The larger it is, the smaller the overlaps need to be made.

On steep roofs, ondulin is placed on top of the previous sheet by 1 wave, while on flat roofs - by 2. This approach is needed in order to protect the house from leaks to the maximum, because water drains quickly from a sharp roof, and from those whose slope angle minimal - very slow.

This rule does not apply only to Smart tiles. It is equipped with a special lock that ensures tightness in any case. The size of the sheet mentioned above is 1.95 meters by 96 centimeters. The area, respectively, is 1.56 square meters (1.9 by 0.864 m).

Ondulin DIY has dimensions of 2 by 0.76 meters. The usable area varies depending on the steepness and slope. So, if the angle is more than 15 degrees, then:

• longitudinal overlap - 1 wave;
• transverse – 170 mm;
• usable area – 1.22 sq. m.

More than 10 degrees and not less than 15:

• 1 wave;
• transverse overlap – 200 mm;
• area – 1.2 square meters.

The slope is gentle from 5 degrees to 10:

For standard ondulin, the size of which is 760 × 1950, the calculation of the usable area is carried out in the same order.

Ondulin Compact has a length of 1 meter and a width of 76 cm. Its usable area is:

• 27 or more degrees of slope - only 57 cm2;
• from 17 to 27 – 53;
• 10-17 – 50;
• 5-10 – 40 cm.

It is also necessary to mention that the height of the ondulin wave is 3.6 centimeters. IN standard sheet There are 10 bends, each with a pitch of 9.5 centimeters.

For those who do not want to bother with calculations, it is possible to calculate the exact amount of ondulin on the official website. There is a special calculator that will also indicate the number of all necessary additional elements.

What is the usable area of ​​ondulin and one of its sheets?

Useful area of ​​one sheet of slate or ondulin tiles – important parameter, allowing you to accurately calculate how much roofing material you need to buy. All main dimensions are given in this article.

Dimensions of ondulin sheet and its usable area

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 appearance the roof was 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 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, 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 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 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 complex roof, then it is necessary to divide it into separate planes - rectangles and triangles, calculate the coverage area for each plane separately and sum it up, adding 5% for waste during installation.

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

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 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: sheet dimensions, usable area, width of ondulin for the roof

Dimensions of one sheet of ondulin and its specifications. Useful area and working size of ondulin sheets for correct calculation of the area of ​​the roof to be covered.

Useful area of ​​an ondulin sheet.

Ondulin roofing materials are presented in three types of sheets, differing in design, dimensions and usable area. For example, Ondulin Smart sheets are equipped with a Smart Lock, Ondulin DiY sheets have a smaller number of waves, and Ondulin Compact sheets, as the name suggests, have small sizes.

The useful area of ​​an ondulin sheet is the area excluding side and end overlaps. Knowing the usable area allows you to quickly calculate the required amount of roofing materials; to do this, it is enough to divide the total surface area of ​​the roof by the usable area of ​​one sheet. The useful area of ​​an ondulin sheet depends on the roof slope. With an increase in the angle of inclination, the useful area of ​​​​roofing materials increases, and when installed on flat roofs, it decreases.

The change in usable area is due to the following reasons:

– at large angles of inclination, ondulin is mounted with a lateral overlap in one wave, and at small angles of inclination, the lateral overlap is two waves;

– with an increase in the angle of inclination of the roof, the end overlap of the sheets increases, and as it decreases, it decreases.

Increasing the side and end overlaps is necessary in order to prevent leaks during heavy rain, with slanting rain and strong side winds. In addition, large overlaps prevent leaks when lenses form from melt water.

The Smart Lock is an additional barrier to water, so the end overlap of Ondulin Smart sheets remains unchanged at any angle of roof inclination and is 12 cm.

Currently, three types of Ondulin roofing sheets are produced: Smart, DiY and Compact. Their main difference is dimensions. The useful area of ​​an ondulin sheet depends on the angle of inclination of the roof.

Useful area of ​​ondulin

Almost all residents of private houses appreciated the advantages of bitumen slate. It is worth noting that this coating has gained its popularity in just a couple of years, when most materials reach such heights only after 20-30 years. This phenomenal success is justified by the fact that the vast majority of private developers erected only gable rafter systems and used slate as roofing material. In Europe, ondulin is called Euroslate, and if you compare these products, you will notice that there is practically no difference, but the properties are significantly different. In this article I will explain to you how the useful area of ​​ondulin is calculated, highlight the strong and weak sides I will describe this material technological process styling

Where does the name ondulin come from and how is it created?

It is not difficult to understand where this name came from if you have at least a little understanding of English letters. The material under the Onduline brand was released by a French company more than 70 years ago. Such a significant period did not in any way reduce the popularity of the material, but on the contrary, strengthened its position. If you didn't know, the residents European countries

products are selected very carefully, regardless of the area in which they will be used. As for our country, here people try to keep up with a more profitable acquisition, very often ignoring its harmful aspects. An example is asbestos-cement slate. It has been used for several centuries, but only a few have decided to abandon this product and began to look for a suitable alternative. It is not surprising that she received ondulin. This material contains a large number of

• components safe for human health. If you don’t know how Euro slate sheets are produced, then I’ll tell you now.
• At the very beginning of production, a sufficient amount of cellulose is prepared. At the same stage, it is cleaned of debris and various impurities that can change the properties of the final product. After this process is completed, a special solution is added to it, making the cellulose very soft. The resulting substance is called pulp.
• Modified bitumen is applied to the resulting cellulose mass on both sides and, after hardening, the material is stored from the stack.
• After the accumulation required quantity sheets, they are packaged and sent for sale.

As you can see, many minor processes are omitted here, which only a plant employee can tell you about, but I hope the approximate scheme for the production of ondulin is clear to you.

How to calculate ondulin for the roof

Calculating ondulin for a roof is not a difficult task at all; it is almost identical to finding the required amount of asbestos slate. TO distinctive features this material can be attributed to standardization. No matter what factory it is produced at, ondulin will have constant dimensions. This factor can affect the determination of a quality product, for example, if you happen to come across Euro slates of different sizes, then know that this is a fake, and, therefore, no one is responsible for the quality.

Define good quality Ondulin can be based on the following characteristics:

• The sheet width is 950 millimeters. Such small dimensions make it convenient when laying on a small or medium area.
• The length is exactly 2 meters. This value was taken based on the length of the most popular slopes; as a rule, it is a multiple of two.
• The thickness of the material is no different from what it was at the production stage and is 3 millimeters. The manufacturer of ondulin warns that this parameter may fluctuate insignificantly, so you should not look for any decrease in quality here.
• Each wave of the sheet should have a height of 36 millimeters.
• The weight of a standard Euro slate is 6 kilograms. As for onduvilla, a covering of 1 square meter will weigh 4 kilograms.

• The area of ​​each sheet is 1.9 square meters.

There is only one way to find the usable area of ​​the material. To do this, take the sheet area and subtract horizontal and vertical overlaps. The resulting figure will show the required area. By the way, for a standard sheet of ondulin it will be 1.6 meters.

Advantages and disadvantages of Euroslate

Despite the fact that the material was made to replace harmful asbestos slate, it still has some disadvantages that negatively affect its popularity. The most pronounced problems include severely limited installation conditions. You can work with this material only in warm weather, somewhere around +10 +25 degrees Celsius.

If the temperature drops below the first value, then the bitumen included in the composition will begin to coarse and lose elasticity and, as a result, simply begin to crumble. In the opposite situation, the ondulin sheet will acquire an overly flexible state, as a result of which the material will sag under its own weight, which is unacceptable for roofing coverings. In addition, Euro slate is laid on a continuous sheathing. All these indicators can become critical when considering this product.

If you are going to lay this product on an outbuilding, be careful, as it does not have fire safety. The body of ondulin can withstand only 110 degrees, after exceeding this value it begins to deform. If a fire occurs, euroslate will maintain combustion for a long time, so it cannot be used as a covering in bathhouses, woodsheds and other similar buildings.

Now let's talk about the good stuff. The advantages of ondulin are as follows:

• Small mass. The lightness of this product greatly affects its installation capabilities. Euro slate can be laid on top of the old coating without dismantling it. To do this, the base is prepared (debris and vegetation are removed), and a simple system of beams is created on top, which will serve as the basis for the new material.
• Long service life. Despite the fact that ondulin contains bitumen, this product can withstand more than 100 cycles of freezing and thawing. This suggests that the minimum service life is 25 years, but in fact this value reaches 40. Reviews written on various construction portals will help you believe these numbers.
• High strength index. The rigidity of the ondulin sheet is determined by the wavy body. Thanks to this structure, it can withstand snow loads of up to 300 kilograms per square meter.
• As you know, bitumen products are distinguished by their very high waterproofing properties and ondulin was no exception. During the entire period of operation, you are unlikely to encounter a situation where, even if the roof is completely intact, it will leak. In addition, Euro slate does not contribute to the appearance of condensation, which is a definite plus.
• Dense leaf structure and its shape easily reflects all noise, so by sending ondulin to the roof surface you will forget about annoying sounds and be able to concentrate on anything.

If you weigh all the pros and cons, the material shows itself in two ways, so it’s up to you to decide whether to buy it or look for something else.

Nuances of installation and transportation of ondulin

As you understand, ondulin is a durable material, but as long as it is in optimal conditions. When purchasing this product, it is very important to inspect each sheet of Euro slate for defects. It is very important to identify cracks and chips here. In addition, pay attention to the size of the sheets and how they are stored. If violations have been noticed, you can safely leave such hardware store or market, you will not find quality products here.

After you have purchased the material, it must be transported to the construction site. Be extremely careful when loading and unloading. The fact is that bitumen material is quite soft in its structure and with a strong impact, the place of damage may be invisible, but after heavy rains it will begin to weaken and a gap will form there, which will cause a leak.

The material can be divided using a saw or suitable power tool. The sheets should be laid randomly so that their joints do not coincide. If you are missing 1-2 centimeters to the end of the slope, then under no circumstances stretch the sheet or try to secure it in this position. After the first frost, such a leaf will simply tear.

When purchasing roofing covering, it is very important to know its size and required quantity. Careful reading of this article will tell you how the useful area of ​​ondulin is located.

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 strong sheets is justified in various areas of civil engineering, from private houses to small shops and office buildings. Therefore, the instructions for installing ondulin will be useful to everyone who plans to carry out roofing work.

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 rafter system under ondulin roofing they can be much thinner. Since this material can be conditionally classified as a soft type of roofing, 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 of 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.

• Once the initial row is securely nailed, you can begin laying the second. Particular attention should be paid 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 or vertical walls on the roof, 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 the top sheet overlaps the base of this element. The windows are also fastened with ondulin nails. Feedback from owners suggests 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.

Another useful element is the 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.

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 an 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 manufacturers solved this problem by covering the sheets with specialized compounds.

The dimensions of ondulin from almost all manufacturers have 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.

Calculating required quantity Ondulin sheets for roofs, 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 angle of inclination from 5 to 10 degrees is the useful dimensions of an ondulin sheet, taking into account overlaps of 1.29 sq.m (the size of the vertical overlap is 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 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 securing 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).

Onduline bitumen sheets have high performance characteristics and are able to withstand heavy loads and climatic conditions. The price of ondulin is distinguished by its affordability, and the material can last up to 50 years. Manufacturers offer several types of this material. They have certain differences and the same performance characteristics. This article will look at the dimensions of the ondulin sheet for the roof, average prices for the material and additional elements.

Ondulin Smart has some differences from the classic ones - it is a lock that helps to install them faster and easier. There are special strips along the edges that protect against water penetration; the size of the overlap has been reduced, which allows you to save on material when covering large areas.

The locks have strips that can be used as guides, helping to make the roof as level as possible. All sheets have markings for nails. Such sheets have standard dimensions of 1.95 x 0.96 m. The thickness is similar to ordinary sheets - 3 mm, and the wave width is 9.5 cm. However, they weigh a little more - 6.3 kg.

Installation of sheets

The price per sheet of andulin roofing makes this material one of the most popular. It also has the advantage of fast and extremely simple installation thanks to special elements. The technology is reminiscent of laying classic flooring, where sheets are laid on lathing or old carpet. The material can be used for roofs with different slopes, and the greater the angle, the smaller the pitch of the sheathing.

While working, you must adhere to some rules:

sheathing can be done from boards, OSB or plywood, a solid base is made if the angle of inclination is less than 10 degrees;

styling we need to start downwind, the overlap is done on one wave, thanks to the locks the rows are even;

Ondulin is modern alternative slate. It is based on cellulose impregnated with bitumen, minerals and pigments. The material is safe and environmentally friendly. And thanks to the size of the sheet, installation does not take much time. The sheets overlap comfortably and are adjusted to the required dimensions.

You can buy ondulin for the roof, the price per sheet of which is 450-550 rubles, in different colors, which will complement the design of the house. Another significant advantage is the ease of installation of the roof due to the light weight of the sheets. This is an additional saving on delivery and the ability to complete everything faster installation work compared, for example, with slate.

Characteristics of ondulin

The cost of ondulin is determined by its certain features and performance characteristics. The roofing itself is similar to regular slate, but includes other components that were mentioned above. This material can be used for arranging the roofs of buildings for various purposes, both houses and social facilities and other buildings. It is absorbed due to the fact that ondulin does not contain asbestos, and therefore it is safe and environmentally friendly.

Sheets are available in the market in four colors - green, red, brown, and slate. The width of each sheet is 0.96 m and the length is 1.95 m. It should be noted that each sheet of ondulin is 4 kg lighter than slate, its weight is slightly more than 6 kg, and its thickness is only 3 mm. But the material itself is very durable, so it can withstand quite heavy loads.

The material is widely used in the construction of various facilities, industrial, commercial, residential or light structures. It is lightweight and can be mounted on flat old roof coverings. The load of the new coating is on average 3 kg per square meter.

Ondulin sheets produced under a French license are sold on the domestic market. The standard sheet is 95 cm wide, 2 m long, only 3 mm thick, and the wave height is 36 mm. There may be a slight error of +/- 2mm wave height, +/- 5mm width and +10/-3mm length.

For the production of sheets, compressed cellulose fiber is used, which as a result resembles ordinary slate. It is impregnated with bitumen, with resins and mineral pigments on top. Thanks to the materials used, the sheet can bend transversely and longitudinally, has a low weight when total area 1.9 m square.

The sheets have 10 waves, the width of which is 95 mm. During installation, an overlap is made in one wave for horizontal laying, and for vertical laying - 10-15 cm when the slope is inclined more than 15 degrees. When laying sheets, the useful area of ​​each in this case is approximately 1.6 square meters. With a slight slope, the vertical overlap is 20 cm, and the sides are two waves. Taking these facts into account, it is necessary to carry out careful calculations with a specialist so that there is no need to purchase additional material.

Cost of material and additional elements

You can buy ondulin roofing, the price per sheet of which is profitable and competitive, produced in France, Italy, Russia and some other countries. The cost of one sheet can range from 250 to 550 rubles. In some cases, a little more or less, it all depends on the manufacturer and its distance from our country.

Additionally, to equip the roof you will need to purchase various additional elements. These include skates, which will cost 300-350 rubles.

The price of ondulin roofing is generally less than other popular materials that are presented on the domestic market. And thanks to the convenient dimensions and light weight of the sheets, the installation process is much faster than when using similar analogues. This coating combines many advantages. It is very strong, durable, stable and suitable for cladding various buildings. The characteristics and versatility of the coating allows it to be used for residential and commercial buildings; the material is safe and made from environmentally friendly components.

The roofing material developed by the French company ONDULINE has been considered one of the most popular in its field for half a century. Today it is produced in many countries, and Russia is no exception.

Despite its great demand, not everyone knows what the usable area of ​​ondulin is, and yet this information is necessary in order to accurately calculate the estimate. Incorrect data often leads to shortages, and then people are forced to buy more material. Of course, there is nothing fatal in this, but it is worth knowing that different batches differ in shade, and as a result, the risk of color mismatch increases.

This material is considered a high-quality coating and can reliably protect your home from rain and snow if all installation work was carried out correctly. The service life is at least a quarter of a century. Moreover, the manufacturer gives a 15-year warranty on the product.

The cost of ondulin is approximately 40 percent higher than that of traditional slate. Therefore, if finances are limited, it is advisable to take the latter. In addition, in the same price range there are several options for modern roofing materials that have similar characteristics and proper quality.

Ondulin copes well with sudden temperature changes, but at the same time it softens in the heat, while in the cold it becomes quite fragile. The latter circumstance explains the ban on working with this coating in winter.

According to the manufacturer, the material can withstand:

• hurricane (up to 200 kilometers per hour) wind;
• large volume of snow (more than 300 kg per square meter of roof);
• hail;
• showers.

It also has good noise insulation properties. This makes ondulin preferable if you plan to build an attic in the attic. Flexibility and lightness make working with it much easier - even an untrained person can handle it alone.

Since ondulin contains only natural materials, it is completely safe. At the same time, the coating is not afraid of:

• fungus;
• mold;
• acids;
• alkalis;
• oils - both synthetic and organic.

Its undoubted advantage is its rich range of colors.

A significant disadvantage of ondulin is its poor fire resistance. Already at temperatures above 230 degrees it can ignite. Moreover, after this it burns on its own, emitting a lot of suffocating smoke. For this reason, it is necessary to carefully weigh the pros and cons if your home is heated by stoves. In this situation, the company recommends insulating pipes from ondulin with special aprons and spark arresters.

Among other things, the coating also fades, since the manufacturer uses natural pigmenting substances. In this case, color saturation is often lost in fragments, resulting in spots appearing on the surface of the roof. In such cases, the roof is simply repainted.

Over time, bitumen may appear on its surface. The company does not consider this a defect.

Sheet sizes

Currently, three variants of ondulin sheet roofing are supplied to the Russian market. They differ in:

• appearance;
• design features;
• usable area.

For example, Smart tiles have special locking systems. At the same time, DIY has fewer waves than a standard sheet. And the Compact version has a small area compared to other products.

The useful area is the area of ​​the roofing material without taking into account overlaps, both end and side. Knowing this value allows you to most accurately calculate the amount of ondulin for your particular roof.

It is only worth noting that the usable area of ​​the same material may differ, depending on the slope angle of the roof slopes. The larger it is, the smaller the overlaps need to be made.

On steep roofs, ondulin is placed on top of the previous sheet by 1 wave, while on flat roofs - by 2. This approach is needed in order to protect the house from leaks to the maximum, because water drains quickly from a sharp roof, and from those whose slope angle minimal - very slow.

This rule does not apply only to Smart tiles. It is equipped with a special lock that ensures tightness in any case. The size of the sheet mentioned above is 1.95 meters by 96 centimeters. The area, respectively, is 1.56 square meters (1.9 by 0.864 m).

Ondulin DIY has dimensions of 2 by 0.76 meters. The usable area varies depending on the steepness and slope. So, if the angle is more than 15 degrees, then:

• longitudinal overlap - 1 wave;
• transverse – 170 mm;
• usable area – 1.22 sq. m.

More than 10 degrees and not less than 15:

• 1 wave;
• transverse overlap – 200 mm;
• area – 1.2 square meters.

The slope is gentle from 5 degrees to 10:

• two waves;
• 300 mm;
• 0.97 m.

For standard ondulin, the size of which is 760 × 1950, the calculation of the usable area is carried out in the same order.

Ondulin Compact has a length of 1 meter and a width of 76 cm. Its usable area is:

• 27 or more degrees of slope - only 57 cm2;
• from 17 to 27 – 53;
• 10-17 – 50;
• 5-10 – 40 cm.

It is also necessary to mention that the height of the ondulin wave is 3.6 centimeters. There are 10 bends in a standard sheet, each with a step of 9.5 centimeters.

For those who do not want to bother with calculations, it is possible to calculate the exact amount of ondulin on the official website. There is a special calculator that will also indicate the number of all necessary additional elements:

• valleys;
• nails;
• skates;
• filling seals;
• waterproofing tapes, etc.
