Bituminous wavy sheet aqualine scheme. Installation of ondulin tiles: a step-by-step overview of the technology of work. Layered sheet construction
When you need to cover the roof of a gazebo, a workshop, or a house with not the strongest walls, preference is given to light roofing. These are shingles, corrugated board and the so-called euroslate - ondulin.
In practice, such a roofing compares favorably with its counterparts: there is no need to painfully draw up a roof pattern, cut metal sheets with sharp edges, and also euroslate pleases with noiselessness and is an excellent competitor to asbestos-cement slate. And it is about his installation that we will tell in this article.
And, although the installation of ondulin tiles is quite simple, for which it is enough to carefully study the manufacturer's instructions, there are still some subtleties and nuances here. Therefore, if you want to equip the roof and safely forget about it for the next 5-10 years, listen to the advice of our experts!
In fact, the roofing, which today is called ondulin, is bituminous corrugated sheets. These are organic or inorganic fibers impregnated with bitumen, which are formed into a ten-wave sheet, with a compressed multilayer structure.
And some manufacturers cover bituminous corrugated sheets with high-density acrylic, which perfectly protects against wind, rain and ultraviolet radiation. The surface structure becomes so smooth that the dirt that settles on the roof is easily removed by rain and leaves no trace.
That is why the whole feature of ondulin lies in its composition. It is based on natural cellulose (popularly - cardboard), with the addition of mineral granules for rigidity, resin, bituminous impurities and natural dyes.
In the factory, cellulose is impregnated with bitumen with additives at high temperature, after which the entire mass is put into a special unit, where it is already given a neat wavy shape by mechanical pressure. That's all! The finished roofing material is light, comfortable and easy to cut with a regular hacksaw (unlike metal tiles, which require a circular saw).
Ondulin is completely different from any roofing. That is why, with the seeming simplicity of installation, it is so easy to make mistakes and ruin this beautiful material. And in order to avoid them, let's first study the features of the Euroslate and what exactly can be done with it.
Regardless of the manufacturer, such a roof looks like this:
Here, at the design stage, decide on roofing cake. Under ondulin you can do as cold roof with an attic, and warm, for a future attic. The fact that ondulin allegedly melts and spreads an unpleasant bituminous smell in the heat is not true if we are talking about branded material.
Of course, handicraft products without identification marks and can not do that. And when euroslate is simply not designed for a hot sunny climate, like Gutta, in which bituminous spots even show through under the sun. Therefore, think about the safety of the roof of your house.
Also, during the installation process, it will be necessary to properly organize the ventilation of such a roof. We have prepared an illustration for you so that you can easily understand these concepts:
It is not difficult to calculate the number of ondulin sheets for roof slopes, the main thing is to know their usable area. So, as we have already said, Ondulin is presented in three versions, and each of them has its own design, dimensions and usable area. for example, Ondulin DIY has fewer waves, and Smart has an additional “smart” Smart Lock, and Ondulin Compact sheets are small in size.
Specifically usable area the sheet area is considered without taking into account end and side overlaps. Just on it you need to divide the area of \u200b\u200bthe slopes, and the exact number of sheets will come out. But remember that the overlap directly depends on the angle of the roof, and the larger it is, the less overlap, and vice versa.
So, at large angles of inclination, it is customary to mount ondulin with a lateral overlap into a wave, and at a small angle, the overlap is made in two waves. On the other hand, the greater the slope of the roof, the greater the end overlap, because this is necessary to prevent leaks during heavy rain, oblique rain, strong wind and puddles of melt water.
Stage II. Studying the features of working with ondulin
In the people, ondulin is called any wavy shingles, for comfort. But there are not so few manufacturers of such roofing, and in appearance their products are practically the same. But the size of the sheets, usable area, weight and fastening features - yes:
Euroslate from Onduline
Let's study the type of "ondulin" that is most popular in Russia. This is Ondulin roofing from the French company Onduline.
It is released at 4 different types. They differ, in fact, only in size and some non-critical chips. Let's look at each of them:
Classic ondulin is suitable for flat roofs, if the angle is from 5 ° or more, and for vaulted, if the radius is from 5 meters. Sheet size 200x95 cm, weight 6 kg, thickness 3 mm. According to some reports, the production of this type of ondulin has stopped.
Ondulin Smart is already a new generation, and is distinguished by applied attachment points, more compact weight, shorter length and smart Smart Lock. Here are its benefits:
- This is a good hydro-barrier, thanks to which the overlap of sheets is reduced by as much as 5 cm, from 17 cm to 12 cm, and this is with the same crate step.
- Thanks to the squeezed-out strips of the lock, water does not get under the sheet.
- The strips themselves serve as guides when laying the sheets, thanks to which general form the roof as a result looks more accurate and geometrically accurate.
All this greatly reduces the weight. finished roof. In addition, new nails come to Ondulin Smart, with special caps that do not open over time (previous analogues sin with this). The dimensions of such a sheet: 195x95 cm, thickness 3 mm. Like the classic one, it has 10 waves per sheet.
Another type of ondulin is DiY. It was designed just for self-assembly, because it has smaller dimensions: 200x75 cm, a thickness of 3 mm, and a weight of only 5 kg. Due to the reduced width of the sheets, more overlaps are obtained here, and the roof is more rigid, due to which it can withstand increased loads.
And finally, Ondulin Compact, which was specially designed for complex and small roofs. It is easy to transport in a conventional car and is not difficult to lay on the roof. Sheets Ondulin Compact - the most small size, only 100x75 cm, thickness 2.6 mm and weight only 2.5 kg. Because the size is smaller, here the overlaps are even more, and the strength is even higher. Each sheet has 8 waves.
Wavy bitumen sheets from Nuline, Aqualine, Bituwell and Ondura
Quite popular in Russia are bitumen sheets from the manufacturer Nuline, which attract with their strength: sheet thickness is 3.3-3.6 mm. Outwardly and by touch, this is the most common ondulin, and this is how it is perceived. Plus, the material is so durable that it is suitable for difficult climatic zones.
The dimensions of this ondulin are 1.22x2.05 m, which is 2.5 m 2 of the roof area. The weight of one sheet is 3.22 kg. The width of such sheets is considered unique, the most convenient for installation, and the entire laying is 30% faster and there are much fewer joints, and, therefore, leaks. Ondulin from Nuline should be laid on the crate with a step of 61 cm, fastened with nails at the top of each corrugation:
Bituminous sheets from Aqualine are also attached to nails, with the same hats and using the same technology. For Bituwell euroslate, nails always come with a closed decorative cap, and also match the color of the roof. But in the kit for ondulin from Ondura, the nails come with a diamond-shaped hat - a rather interesting design move.
Stage III. Choice of fasteners for mounting
For the installation of bituminous corrugated sheets of the ondulin type, special roofing nails. They are also called hardware, metal products.
Such nails are noticeable wide hat, which securely presses the roofing sheet to the crate, and at the same time does not damage them. And there is no risk that with more effort the nail will go through. Zinc anti-corrosion coating protects against moisture.
Moreover, the hats themselves can be fused or monolithic. These hats are made from polyethylene. low pressure, due to which they are shockproof, airtight, resistant to temperature extremes and are not afraid of ultraviolet radiation:
The stem of the nail is made from carbon steel to be more durable. Its annular profile helps the nail stay in the crate. As roofers like to joke, a screw hammered into a wall holds better than a screwed nail. Here this principle is just implemented!
And a special conical shape makes it easier to drive a nail, but then tearing it out of the ondulin will no longer work. Standard size nails for ondulin is as follows: diameter - 3.55 mm, length - 75 mm.
To achieve aesthetics, ondulin caps are painted according to the same catalog as roofing sheets, and such fastening is imperceptible against the background of the entire roof:
Moreover, each manufacturer of bituminous corrugated sheets produces its own fastening. One believes that the hats should be made smaller and inconspicuous so as not to spoil the roof pattern, and the other believes that neat dots on the slope look beneficial, and highlights them both in color and size.
Here is an example of a fastener hidden from the eye:
By the way, some types of euroslate from Western manufacturers are not laid on nails, but on special brackets and mounting foam:
If you find such a mount on sale, take it boldly, because something similar is used to mount piece natural tiles.
Stage IV. Preparation of sheets for installation
To cut ondulin, you will need the following tools: a hacksaw and a hammer. Be sure to grease the hacksaw with oil. so that it does not get stuck in bitumen:
An alternative is manual and circular electric saw:
Here is one of the options for how to cut ondulin:
During installation, move along the roof using building bridges or stairs. Try to stretch and compress the sheet no more than 1 cm, although it looks elastic.
Stage V. Laying sheets on the crate
It is possible to lay modern ondulin both on wooden and on metal crate:
The crate for all types of ondulin is mounted according to the same principle, regardless of the size of the sheets and the manufacturer:
- If the roof angle is from 5 to 10 °, then a continuous crate is needed.
- If the angle is in the range from 10 to 15 °, the crate pitch should be 45 cm.
- If the slope angle is from 15 ° and above - then 61 cm.
For solid battens take edged board 25 mm thick, OSB boards or moisture-resistant plywood, and for sparse bars with a section of 40x60 mm.
Here is an example of how simple crate needed for small gazebo:
Before installation, be sure to check the slopes for squareness. Install sheets at temperatures from -5°C to +30°C. Ondulin is always laid starting from the leeward side:
Lay out the first row from the bottom of the roof, from the edge that is opposite to the edge of the roof. Start laying the second row from half a sheet. It is important that the corner joint is overlapped in 3 sheets, and not in 4, so that later the corner does not deform ^
To fix the sheet, you need 20 nails. Just do not drive nails into the wave on which the next sheet will overlap. First of all, fix the sheet at the four corners. Next, fasten the bottom of the sheet, for each wave.
Make sure that the edges of the sheet are fixed to the crate. As a result, the sheet should recede 5-7 cm from the edge of the crate. Install on top cornice plank, which has special places for bending (this is how the overhang is adjusted). And to close the gap under the sheets from the side of the cornice and provide ventilation, use a filler.
If you work with a Smart Lock, then you are in luck, because the guides here will help prevent accidental shifting of sheets. The cornice will turn out even and neat. Fasten each sheet of Ondulin Smart with 20 nails, directly along the mounting markings, stacking the sheets themselves in a checkerboard pattern.
At the beginning of each of the even rows, lay half the sheet. You should succeed so that the side overlaps of the sheets fall in the middle of the sheets of the lower rows. Ondulin Smart has an end overlap height of 12 cm.
When the sheets are laid, complete the construction of the roof with special accessories: tongs, valley, ridge, special sealing tapes Onduband and Onduflash, universal ventilated aggregate and breathable tape Ondulair Slim. And if the roof has internal bends, they need to be closed with special valleys, which are usually supplied with roofing sheets:
When all the sheets are laid, decorate the roof overhangs with special additional elements:
Ondulin is such a light and easy-to-install coating that you can’t think of anything better to update the old one. On the other hand, an outdated roof under euroslate will also serve as a good foundation.
Plus, the benefits that installation brings new roof to the old one:
- There are no costs for dismantling the old roof and mountains of garbage.
- Save time by not having to re-roof.
- No matter how fragile ondulin may seem, now the inner pie of the roof is securely protected.
- Double Leak Protection!
This is how the technology of installing ondulin on an old roof looks like:
Let's take a look at the technology for attaching euroslate to an old roof in steps:
- Step 1. Assess the condition of the roof and how strong wooden elements roofs: beams, rafters and lathing. If you notice dilapidated elements, be sure to replace them or strengthen them.
- Step 2. Now fill the bars along the rafters for the future fastening of the ondulin.
- Step 3. Install the crate with the same step as for the usual installation of ondulin. You can use the manufacturer's instructions for this.
- Step 4. Now install 10 cm from the ridge on the slopes additional elements crates - there will be another full-fledged skate.
- Step 5. To improve appearance roofs, install on the eaves drainage system and drip.
In practice, everything looks like this:
We have tried to collect for you in this article all the most helpful tips and the recommendations of experienced roofers who had to work with ondulin. Of course, the manufacturers themselves are not eager to announce all these pitfalls and peculiarities in installation, because the brand must be kept. And you, if you are going to work with this material, such knowledge will just be useful!
1. VENTILATION
Make sure that adequate ventilation is provided (according to DIN4108). The gap between the Aqualine coating and the roof surface must be at least 8 cm. If necessary, sufficient ventilation can be achieved with additional elements.
Humidity screen ( lining carpet) is necessary if the room under the roof area has high humidity: kitchen, bathroom, bath.
2. AQUALINE MATERIALS MUST BE INSTALLED AT TEMPERATURE ABOVE 0°C
When installing a roof made of Aqualine materials, walk only on those places of the roof that have support from below.
INSTALLATION OF ROOFING MATERIAL
1. REQUIRED TOOLS
Hammer, saw, tape measure, nails.
2. DISTANCE BETWEEN THE CRATE
Depends on the angle of the roof. Required dimensions are shown in table 1. The minimum roof pitch is 7°.
(A, B, C, D see Fig. 2)
3. FIXING AQUALINE WAVE SHEETS
Always start working from the bottom corner of the roof and against the direction of the prevailing winds.
Fix the sheets with nails according to the scheme shown in Figure 2.
To calculate the amount of overlap, use the data in table No. 1.
Drive nails vertically into the top of the wave (Figure 3).
The procedure for driving nails is shown in Figure 4.
Wavy bituminous sheets, or, as they are also called, Euroslate Aqualine, are produced in Belgium, in the city of Antwerp. The ASBO plant, which manufactures this popular roofing material in Europe, is considered one of the world's leading manufacturers of products with high performance waterproof. High-tech production, equipped with modern equipment, allows the plant to produce Euro-slate, which fully complies with rigid European standards EN534 for bitumen sheets, as well as the international quality standard ISO 9002.
A mixture of organic and inorganic fibers is used to produce Aqualine corrugated sheets. She is pressed under high pressure and then impregnated with bitumen under vacuum. This method allows you to guarantee a high uniformity of the roofing material and does not allow moisture to penetrate into its structure. The fibers interlock with each other in a direction parallel to the direction of the sheet. This ensures the strength of the euroslate and at the same time makes it flexible enough to make the installation of the roofing material as convenient as possible.
Aqualine sheet characteristics:
- Length - 2 m
- Width - 0.92 m
- Total area (useful) - 1.84 sq.m (1.54 sq.m)
- Wave height/width - 36 mm / 92 mm
- Number of waves - 10
- Sheet weight - 5.6 kg
Advantages of Euroslate Aqualine:
- is a modern roofing material
- easy to transport, easy to use
- can be mounted over the old coating
- has a glossy self-cleaning surface
- economical and environmentally friendly material

Bituminous corrugated sheets Aqualine - a product of high technologies!
Aqualine - corrugated bituminous sheets. This roofing material is produced by ASBO Antwerp (Belgium) in the heart of Europe on an ultra-modern production line using the latest technology.
ASBO is part of the ATAB group, the world's leading manufacturer of waterproof materials:
- The company has been producing waterproof materials and roofing materials for 100 years;
- Export of goods is carried out in 60 countries;
- In the research center of the corporation, environmentally friendly technologies are studied, new developments are carried out, and product quality control is carried out.
Unique technological excellence
Aqualine differs from traditional bituminous corrugated sheets with the latest industrial manufacturing methods and the resulting high quality.
Layered sheet construction
Aqualine is formed from a homogeneous blend of organic and inorganic fibres, in a highly compressed multi-layer construction that creates a strong internal bond between the layers. The fibers are positioned parallel to the direction of the sheet, which increases the hardness and flexibility of the material needed for ease of installation. The multi-layer construction of the sheets also guarantees particularly good results from deformation upon impact.
Optimum mechanical performance
Aqualine is a product with enhanced sheet hardness and a very sharp wave angle (40°).
Unique aesthetic excellence
vacuum impregnation
Vacuum impregnation in an airless volume guarantees a completely homogeneous saturation with bitumen and eliminates the possibility of moisture ingress.
This technology has other advantages:
- sheet contains more bitumen;
- vacuum impregnation occurs at low temperature, which prevents thermal deformation.
High density painted surface
The surface treatment with high density acrylic increases the durability of the corrugated sheet and also protects the main components of the sheet from UV radiation from the sun, wind and rain.
ASBO guarantees the quality of the connection between the substrate and the coating.
Self-cleaning profile surface
Due to its coating, Aqualine has a smooth surface structure, as a result of which atmospheric pollution is quickly removed by precipitation.
