bituminous sheets. Roof covering “Nuline”. Dimensions and appearance of Nuline sheets

Bituminous corrugated sheets are organic fibers impregnated with bitumen. Formed into a ten-wave sheet from a homogeneous mixture of organic and inorganic fibers, they have a multi-layer tightly compressed construction that guarantees good resistance to deformation upon impact.

FROM front side sheets are covered with a protective and decorative paint layer based on polymers and light-resistant pigments. The surface treatment with high-density acrylic increases the durability of the roofing sheet, and also protects it from the ultraviolet radiation of the sun, wind and rain. Due to its coating, bituminous corrugated sheets (Euro slate) have such a surface structure that dirt from the atmosphere that has settled on the roof is removed by rain and sliding snow. For decorative design roofing offers several options for coloring sheets.

Euroslate is used not only in new construction, but also for repairing old roofing by laying new roofing sheets on it without removing the old roof. Euro slate laying does not require any special training. The material is easy to cut hand saw and fastened special nails with sealing cap. One person is enough to install the euroslate.

On the Russian construction market, there are materials from several manufacturers of corrugated bitumen sheets (Fig. 13) with similar dimensions and technical characteristics.

Rice. 13. Bituminous corrugated sheets and fittings

When installing euroslate, follow the instructions of the manufacturer of the material, paying special attention to the requirements for the crate. Otherwise, the installation of bituminous corrugated sheets different manufacturers are not much different.

Typically, corrugated bituminous sheet roofing on flat roofs with a pitch of 5 to 10° (1/11 to 1/6) requires continuous sheathing of planks, moisture-resistant plywood, or OSB boards(OSP). Term continuous crate from the boards does not mean at all that the boards should be tightly pressed against each other, on the contrary, when laying between them, a gap of up to 5 cm is left. butt The overlap of euroslate sheets on each other with such a slope is equal to 300 mm, the side overlap is 2 waves.

On roofs with a slope of slopes from 10 to 15 ° (from 1/6 to 1/4), a crate of wooden bars with a section of 40 × 50 (h), 50 × 50 mm and an installation step of 45 cm along the axes is needed. In this case, the front overlap of the sheets is 200 mm, the side overlap is 1 wave.

Roofs with slopes of 15° and above (from 1/4 and less), the step of the lathing bars can be increased up to 60 cm along the axes. Frontal overlap - 170 mm, side - 1 wave (Fig. 14). In areas with a heavy snow load or with potentially large snow drifts on the roof, the interval between the laths of the battens should be left the same - 45 cm. If there is any doubt, it is recommended to further reduce this interval.

Rice. 14. Lathing under euroslate

The crate is made with an overhang a little longer than required. For precise positioning of the pitch of the lathing bars, a template cut from the lath trim is used. Eaves overhang roofing is provided by a filly - a board nailed to the lower end rafter leg. Thus, on gable roofs with an overhang of laths and a filly length, it is possible to reduce or increase the size of the entire roof slope, adjusting it to the most favorable cutting of the roof. For example, knowing usable area covering one roofing sheet, the size of the roof slope can be adjusted so that the number of cuts is minimal or so that the cuts can be used on another slope. Therefore, during the construction of the roof, it is better to make laths and fillies longer than required, then it is easier to saw off the excess than to build up the missing one.

For roofs of complex shapes, the cutting of the roof is done in special computer programs with the call of the measurer on the object. For simple roofs, it can be done on graph paper and tracing paper (Fig. 15). To do this, the position of the roofing sheets is drawn on graph paper, and the plan of the roof slope is drawn on tracing paper. Tracing paper is superimposed on graph paper and shifted along it until it is found optimal solution. When predicting the cutting of hip roofs, you need to make sure that the top of the corner sheets is on the lath, otherwise it will be difficult to fix them, you will have to install bars with hemming along the edge of the hip. Along the length of the slope, cut sheets can be placed both at the cornice and at ridge knot. According to the width of the slope, as an option, you can not stack a whole number of sheets with a remainder on the edge, but cut one sheet lengthwise and put it in the center or any other place in the row, then the outermost sheet of the row will turn out to be wider and fit well on the crate.

Unsuccessful cutting, corner sheets do not lie on the crate

Unsuccessful cutting, a lot of illiquid scraps

Successful cutting, corner sheets lie on the crate, and trimmings can be used on another slope

Rice. 15. An example of cutting a slope of a hip roof

Euroslate manufacturers recommend starting the second row of roofing sheets with a sheet cut in half, in which case a good “run-up” of overlaps is obtained. However, this is true only for rectangular slopes, on which an integer number of sheets is obtained in the first row. If a hip roof is made (with trapezoidal slopes) or a gable roof (with rectangular slopes), on which an integer number of sheets does not fit, you can deviate from this rule. Both the first and second rows can be started with a sheet cut along the width of which will give the least amount of waste along the entire slope. The main thing is that the overlap of the second row is not combined with the overlap of the first row, otherwise it will have four layers of roofing. If the combinations longitudinal edges cannot be avoided, then the corners of the roofing sheets are cut off (Fig. 12). In this case, when predicting cutting on tracing paper, it is better to draw roofing sheets, and on graph paper the slope of the roof. Apply tracing paper to graph paper and move until there is best option cutting.

Before laying the sheets on the roof, the squareness of the gable slopes is checked or marked, which is more desirable (Fig. 16). On the hip roofs in advance, even at the device truss system, you need to try to make the angles of inclination of the hip ribs the same. This is provided correct markup and laying Mauerlat beams and girders. Only the same angles of inclination of the hips allow waste-free use of trimmings on opposite slopes.

Rice. 16. Checking or marking the right angles of the roof slopes and a way to eliminate small errors

The squareness of the slopes is checked (marked) using the right triangle formula: the length of the hypotenuse should be equal to square root from the sum of the squares of the legs. To check (mark) right angles, you can put together a right-angled triangle with sides: legs - 3 and 4 m, hypotenuse - 5 m or legs 1.5 and 2 m, hypotenuse - 2.5 m. You can not make a triangle, but use two roulettes : alternately postponing the legs and checking the length of the hypotenuse. It’s hard to say what to give preference to, climbing on the roof with both tape measures and triangles is not very convenient. After determining the squareness of the roof slopes, the trim lines are “beaten off” with a coated thread, the “extra” length of the laths and fillies is sawn off. Euroslate manufacturers allow some deviation of the slopes from right angles. Euroslate flexible material, so it can be slightly stretched or compressed, like accordion furs, but not more than 2% of the original width. For sheets with a width of 950 mm, this is no more than 2 cm, for sheets with a width of 1220 mm - 2.5 cm.

Installation of the roof is done towards the prevailing winds () at positive temperatures. The bitumen with which the sheet is impregnated "does not like" frost, the sheet becomes hard and brittle. Bitumen also “does not like” the scorching sun, the sheet becomes too soft and supplely changes shape when nailed too tightly.

To install the first sheet on a rectangular roof, mark the width of the roofing sheet from the corner along the eaves and make a mark with a colored pencil. Then measure the same width and mark along the roof ridge. Mark off a chalk line connecting these two marks. To determine the length of the free roof overhang over the eaves, drive nails into the corner rafters and stretch the twine from corner to corner at a distance of 4.5–7 cm from the eaves along its entire length. It is necessary to make a reservation here, different manufacturers of euroslate recommend different sizes of free overhang for their sheets, which range from 4.5 to 7 cm. This value depends on the thickness of the corrugated bitumen sheets. Adhere to the free eaves recommended by the roofing manufacturer. If the overhang is made larger, then the edge of the roof will bend down either under the weight of snow or under the scorching sun.

Lay the first sheet, aligning it with the string stretched from corner to corner and the chalk line. If the roof slope is rectangular, the sheet will align well with them, it must be immediately fixed with nails. If the ramp is not rectangular, align the sheet along the cord and nail it in one wave along the length of the sheet, and stretch or compress the other side, aligning the sheet along the edge of the slope or along the chalk line. It is desirable that the chalk line be perpendicular to the lace stretched along the eaves, then aligning the first sheet along the chalk line and lace and pulling it aligned to the edge of the slope, this procedure will not be needed anymore, the remaining sheets of the first row will lie flat, they will need to be leveled only along shoelace. When using wind corners in the roof, it is not required to level the edge of the sheets along the edge of the slope, small errors in the squareness of the slope will be covered by the wind corner.

Corrugated bitumen sheets are fastened in a strict sequence (Fig. 17): first, the edges of the sheet are fastened, then the middle, then the rest of the nails are finished. The sheets are flexible, if this sequence is not followed, then by accidentally constricting a heavily hammered nail, you can change the geometry of the sheet. For example, if you consistently drive nails alternately into each wave of a sheet, then with heavily hammered nails you can roll it into a “pancake”. Compliance with the rule of order of fastening will “forgive” an inadvertently heavily driven nail. Nails are not hammered into the last crest of the wave (or into the last two crests), it will go under the overlap of the second sheet and will be fixed when this sheet is fastened. Nails are not hammered in the upper part of the sheet either, there will be an overlap with sheets of the second row, followed by fastening. If a corner wind corner is used, then the nails are not driven into the crest of the first wave, it will be fixed together with the installation of the wind corner fitting. The corner fitting is fastened with nails or fixing screws through the flange of the fitting and the crest of the sheet wave to each lath.

Rice. 17. Rules for installing corrugated bitumen sheets (circles show the sequence of driving nails into sheet waves)

In the first and last sheet of the row, nails are driven through the extreme wave into each lath and through each crest of the sheet wave into the lower lath; in the middle of the sheet, nails are driven through the wave and through the lath. 22 nails are driven into an ordinary ten-wave sheet of the roof with a lath spacing of 45 cm. The first row of nails is driven into each wave crest, then in a checkerboard pattern.

The second and subsequent sheets of the first row are installed with alignment along the cord, which regulates the amount of free overhang. With especially high-quality work, for each subsequent sheet of a row, a chalk line is beaten off from the cornice to the ridge, perpendicular to the cord and regulating the width of the sheet. These lines will not visually allow you to drag the roofing sheets with strong nailing and change their geometric dimensions.

The second row of sheets begins with a sheet cut along, dividing it into two or more parts, if required by cutting the roof. The main purpose of cutting the first sheet of the second row: to avoid overlap a large number layers, secondary - aesthetic, make longitudinal joining seams in a checkerboard pattern. Although at a great distance, namely from there, you can see the roof, the side joints of the sheets are almost invisible. The sequence of installing sheets of the second row is the same as that of the first: the coated line is beaten off, the sheet is leveled along it and nailed. It is necessary to monitor the amount of overlap, it must correspond to the slope of the roof. If the battens of the crate were set carefully and according to the template, then the overlap will be obtained automatically.

Sheets are cut along the length with a sharp cutter along the wave cavity. Width cutting is done with a wood saw with an oiled blade or electric saws: circular or jigsaw. It is better not to use a grinder with emery discs, they will melt the bitumen. Nails are hammered only into the crest of the wave perpendicular to the crate. An unsuccessfully hammered nail is pulled out with a lining under the stop of the nail puller, cutting a pipe with a diameter approximately equal to the depth of the wave of the sheet (Fig. 18).

The prichelina, in the place of the side overhang of the roof over the gables, is designed in two ways: using a corner fitting and bending the roof on wind board(Fig. 19). The second method is recommended to be done only in warm weather when from solar heating euroslate sheets become soft, or the roof overhang needs to be heated with hot air from a building hair dryer.

Roof adjunctions to walls, valleys and ridges are made in the same way as on roofs made of asbestos-cement corrugated sheets using shaped parts attached to euroslate. The difference in the work is that the fastening of the euroslate style is made in each crest of the wave of roofing sheets or in each lath. Once again, we recall that, unlike hard asbestos-cement slate, euroslate is a soft material, which is why so many nails are driven in. In addition, special self-adhesive waterproofing tapes are made for euroslate, thanks to which there is no need to create niches in the walls and bricks on pipes (Fig. 20. However, waterproofing tapes do not exclude the use of traditional roof junctions to walls and pipes. On the contrary, sharing in these knots of niches, brick overlaps and waterproofing tapes increases the reliability of the roof.

Fractures of the roof slopes are arranged using isosceles corner parts. One shelf of which is brought under the roof of the upper slope, the other is put on top of the roof of the lower slope (Fig. 21).

For the ventilation of the under-roof space, depending on the roof structure, breathable linings can be installed under the bituminous corrugated sheets. Their use will provide penetration under the roof air masses and drying inner surface roofs, battens and rafters, while limiting the entry of birds and insects under the roof.

Among the popular roofing materials, not only for their qualities, but also for their low price, one of the first places is occupied by bitumen sheets. They are often classified as a variety of ordinary slate and it is called euroslate. The composition of this material includes organic fibers impregnated with bitumen and painted on both sides or only on one side.

The advantages of a corrugated bitumen sheet are undeniable and the most pronounced of them are as follows:

• optimal sheet format and light weight;
• water resistance and resistance to alkalis and vapors;
• high elasticity;
• installation of bitumen sheets does not require additional preparation - here you just need to follow the instructions that you get in any store where bitumen sheets are purchased;
• sheets are easily cut with a hand saw and fastened with nails with a sealing cap;
• installation is easy to handle even by one person;
• and of course low price material combined with excellent performance;

With the help of this roofing material, you can easily and quickly, and most importantly, affordable, replace the old coating with a new coating. At the same time, bitumen sheets can be laid even without dismantling the old coating. Due to the fact that the material has a low weight, its load on the entire structure will be very insignificant, which will make it possible not only to save cash but also to improve thermal insulation and ventilation conditions.

Bituminous sheets look like a piece of organic material. Due to the fact that this is not a brittle material, the sheets do not break during laying, which significantly reduces the scrap rate.

Among other things, bituminous sheets serve for a long time, and if properly installed, they serve for about 15-20 years.

Bitumen sheets have their own advantages due to manufacturing technology, and it is as follows:

• binder composition bituminous material improved due to polymer additives, which makes bitumen more resistant to temperature changes and makes it less brittle;
• due to the fact that bitumen softens when high temperatures, it is left in this form for more long time, as a result of which it becomes more elastic, this improves its quality. In order to give bitumen such characteristics, materials such as styrene-butane-styrene, as well as polypropylene, are used.

Such a roof will not lose its flexibility for a long time, and will withstand even very low temperatures. It is practically not affected by precipitation, including ultraviolet radiation.

The bitumen sheet also gained strength and durability due to the fact that the cardboard base, which was earlier, has now been replaced with a more durable one. These bases are made on the basis of glass and synthetic fibers. They repel water well, do not rot, are strong and durable.

• bituminous sheets are universal in application and look great on buildings with complex shape roofs.

Disadvantages of bitumen sheets

• despite the fact that the service life of such a roofing material is about 20 years, this is significantly short compared to the service life that other roofing materials can provide. roofing materials. Thus, it can be said that this material is not durable.
• restrictions on the installation of the material - it can be used on roofs with a slope of at least 10 degrees, while on slopes from 10 to 18 degrees it is important to use a special underlay.

The composition of the sheet, as a rule, includes the following elements: distilled bitumen, cellulose fibers, minerals (filler), thermosetting resin and mineral pigments. On the front side, the sheets are painted with a protective and decorative layer of light-resistant pigments. Sheets are issued from matte surface with painting in one layer, and with a glossy surface, with painting in two layers.

Wavy bitumen sheets are easy to install, their laying does not require professionalism and special equipment. The sheet weighs about 6 kg, which allows you to make a simple crate. They can be mounted directly on the old roof, regardless of its condition.
Wavy bituminous sheets are characterized by a whole range of colors: red, brown, green, black and others. The average dimensions of all types of sheets are 2000x1000 mm.

Sheets are well bent and along a wave. With a curvature radius of 5 m or more, they can be laid on curved surfaces. Sheets can be used not only on the roof, but also as a lining of vertical surfaces. It can be a waterproof screen or a fence.

Euroslate production technology.

The unique production technology of Euroslate is as follows: cellulose thread is pressed under high pressure into a fabric up to 20 layers, which is then impregnated with special polymer-bitumen compounds. Due to the pressing, the fibers form a layer-by-layer intersection, which gives the sheet a special strength. As a result strong connection layers impregnated with bitumen, water absorption is completely excluded.

On the initial stage production, the upper layers of the sheet are impregnated with natural dyes (Naturcolor). Newest technological process production completely eliminates the possibility of peeling and peeling paint. The coating does not fade in the sun, that is, it is resistant to UV radiation. Color palette sheets are fully developed some time after installation under the influence of sunlight. Due to the natural oxidation of bituminous sheets, the surface of the sheet becomes lighter, the colors acquire maximum saturation.

Installation of bituminous fibrous sheets.

1. The pitch of the lathing is set depending on the slope of the roof. The minimum roof pitch is 7°.

2. Corrugated sheets are cut with a wood saw, which should be lubricated with machine oil to prevent jamming. You can also use a circular or hand saw.

3. Start the installation of corrugated sheets from the edge of the roof opposite to the prevailing winds. Start the installation of the second row with half of the bituminous sheet.

The following table shows the features.

Bituminous corrugated sheets are an inexpensive and practical roofing material that is durable and easy to install. Outwardly, it resembles asbestos cement sheet but is much lighter in weight.

Features of production and scope of material

Bituminous sheets are modern material, which is based on cardboard-cellulose fibers or polymeric canvases impregnated with high-quality modified bitumen.

Wherein upper layer material is covered with resin, which protects the sheets from external influence ultraviolet and damage, and also impregnated with mineral dye, which gives the sheet specific color or shade.

In practice, bituminous sheets are used for the reconstruction of an old roof, laying a new roof, and in some cases for wall cladding. Can be used on roofs with a slope of 12 to 90 degrees, which makes the material versatile.

About varieties of bitumen sheet

Roofing bituminous corrugated sheet is presented on the market today by both domestic and foreign manufacturers. The most popular brand of bituminous corrugated sheets as Ondulin, whose name has already become a household name.

Today euroslate of this manufacturer can be found in more than 100 countries around the world. Also worth considering similar material and other brands of no less quality and durability:

bituminous sheet trademark Gutta- produced by a Swiss company, highly resistant to bright sunbeams and chemicals.

Euroslate Aqualine- a product of a Belgian manufacturer, consists of 21 layers of perpendicularly arranged cellulose fibers. This gives the sheet a sufficiently high rigidity, which does not prevent the material from having good flexibility, which makes it possible to use it on roofs of complex geometry.

bituminous sheet Bituvel- equally well suited for roofing and wall decoration. The guarantee for the product of German origin is up to 15 years, so it is very popular in the world. More than 20 countries give preference to it.

Euroslate Bioline- a product of a relatively young Ukrainian company, which uses light-resistant pigments of a German brand in its production, so even after prolonged use, the sheets do not lose their rich tone.

About the advantages of the material

Bitumen sheets for roofing , According to experts, they have become so popular because of their affordable cost and durability. So, for example, the average price of a sheet produced by Ondulin will be only 350 rubles.

It is also worth noting other advantages of euroslate:

• Low water absorption due to special impregnation given material perfectly resists the penetration of water, completely protecting the under-roof space from moisture.
• The possibility of using the material in a wide range of temperatures from low negative to high positive.
• Strength. Bituminous sheets, thanks to solid foundation, well resistant to mechanical damage, and with a properly calculated cross-section of the crate, the material is able to withstand solid snow loads.
• Wind resistance - according to research, bituminous roofing sheets are able to withstand strong gusts of wind, reaching up to 192 meters per second.
• Good flexibility - thanks to this parameter, euroslate can be used for roofing of various configurations and complexity.
• An extensive range of colors that allows you to give the roof an attractive and aesthetic appearance.
• High level of sound absorption, thanks to which even heavy rain and hail will not cause discomfort not only in the premises of the house itself, but also in the attic.
• Lightning protection. Unlike metal roofing, bituminous sheets are not capable of accumulating static electricity.
• Safety for humans, the material does not emit toxic substances when heated.
• High resistance to chemicals and aggressive environments.
• Saving lumber, since the sheets are light in weight, it becomes possible not to make the elements of the truss system reinforced.
• Ease of installation, a person who does not even have much experience will be able to cope with such work roofing works, and this in turn leads to savings in construction, since there is no need to invite roofing specialists.
• Affordable cost.
• The elasticity of the material, thanks to which it is possible to mount the roof even at sub-zero temperatures.
• High resistance biological destruction- mold and various fungi do not form on the material.
• Possibility to lay euroslate without dismantling the old roof.

The subtleties of mounting bitumen corrugated sheets

• Slope angle.
• Roof area.
• The length of the ridge, valleys, grooves and all junctions to vertical surfaces.
• The number of penetrations arranged for the chimney or ventilation pipes..

In order not to exceed the consumption of material, an accurate calculation is needed, which can only be done by specialists. They will be able not only to calculate the amount of material, but also determine required amount additional components of the roof.

Installation instructions for corrugated sheets:

Installation of roofing material begins with the fact that it is necessary to prepare the base for laying euroslate.

Unlike the one used for the installation of metal or other piece materials, it should be solid if the slope of the roof slopes does not exceed 10 degrees.

What is used for unedged board, with pre-treated edges (bark removal is mandatory).

Solid flooring must be level and dry. For reliable waterproofing under bituminous sheets, additionally laid lining layer, for example, from, which is fixed to the base with a construction stapler. With large slopes of the roof, the crate can be arranged in large increments, and bars with a section of 40x50 or 50x50mm can be used for its manufacture.

Markup on bituminous sheets it is convenient to apply with colored pencils or markers, for cutting it is better to use a simple hacksaw for wood or circular electric saw. To ensure that the tool does not get stuck in the material during the cutting process, its cutting surface must be pre-lubricated with oil.
