Installation of ondulin: step by step instructions

Ondulin is a rather popular roofing material of undulating shape, produced on the basis of cellulose, resins, fillers, mineral additives and bitumen. It has a significant number of advantages, in connection with which the use of this material will allow you to forget about the problems with the roof for several decades. With the arrangement of the roof, ondulin is one of the most profitable materials. Consider the features of its operation and installation in more detail.

Advantages of

Ondulin has a number of characteristics that have made the material widely distributed in constructionworks. In particular, it is possible to distinguish such aspects as:

• waterproofness - the material does not absorb moisture even with prolonged contact with it. When using ondulin, even the installation of vapor barriers and waterproofing is optional;
• resistance to temperature effects - ondulin does not lose its performance in high and low temperatures, and is also able to withstand sharp changes;
• a relatively small mass of this roofing material allows to avoid significant loads on the frame of the building;
• due to the high resistance to ultraviolet rays, the intensity of the color of ondulin does not decrease even under conditions of constant exposure under direct exposure to the sun;
• material is resistant to the negative effects of alkalis, acids, diesel fuel, mineral oils, due to which it can be successfully used to cover not only residential but also industrial premises;
• long service life - 50 years or more;
• the cost of the material is relatively low, so that the ondulin belongs to the category of widely available construction products;The
• does not require special care;
• high aesthetic performance;
• environmental safety;
• with this roofing material is easy enough to work. If desired, you can perform installation ondulin with your own hands and this will not require special skills or construction skills;
• due to the universality of the ondulin it can be used not only as a roof covering, but also for finishing vertical surfaces;
• due to biological inertness the material is absolutely not susceptible to the effects of fungi and bacteria.

Criteria for choosing

In order not to be mistaken in the choice of ondulin, it is necessary to focus on the following criteria:

1. You can distinguish a quality product from the black corrugated mesh that is on the reverse side of the material.
2. The sheets must have 10 waves, the height of each is 3.8 cm.
3. The outer side is rough. Color of the material is matte.
4. The last wave must be printed with the manufacturer's code.
5. The products are accompanied by a certificate, a manual for use and a coupon providing a 15-year guarantee.

How to calculate the required amount of

material The size of the ondulin sheets is 0.95 mx 2 m. To determine the amount that is required for work, it is necessary to make the following calculation:

1. Initially, divide the roof surface into geometric figures - triangles, squares, trapezoids.
2. Next, using geometric formulas, it is necessary to determine the area of ​​each of the figures.
3. The results obtained are summarized, where the final figure will be equal to the roof area.
4. Now it is not difficult to calculate the required number of sheets. The area of ​​the roof is divided by the index of the useful area of ​​the material.

Installation of the ondulin: recommendations for the work

1. Ondulin is recommended to be mounted on a wooden crate made of uneven bars, since this design better distributes the load. The most suitable material is the beams from coniferous species. Such wood has a special structure and has in its composition resins that inhibit the development of various bacteria. All parts of the crate must be treated with antiseptic agents. But it is allowed to install sheets on a metal frame.
2. During the fastening process, the required distance between the beams, depending on the roof inclination, should be taken into account.
3. The first stage of erection of the crate is the fixing of the eaves and the elements that will hold the gutters.
4. Ensure that the board has a large cross-section at the beginning of the overhang. The distance between it and the next board should be 30 cm. The first board should be installed so that it protrudes from both sides of the eaves. The rest of the boards are fixed in parallel.
5. With the help of a color pencil on the sheets, marking is made, according to which the material is cut.
6. Start the installation work from the edge in the direction opposite to the direction of the wind.
7. The sheets should be arranged in such a way that the joints of the next row do not coincide with the joints of the previous one, that is, according to the chess order. This will avoid leaks. To achieve such an arrangement of the material, each successive series should start not with a whole sheet, but with halves.
8. A hacksaw is used for cutting, but in the absence of this tool, an electric jigsaw or an ordinary knife will do.
9. The top sheets must be placed on the bottom with an overlap of 14-15 cm.
10. For fixing to the wooden frame, nails of polyvinyl chloride or polypropylene are used, which need to be placed only vertically. In the opposite case, there is a possibility of damage to the roof.
11. If it becomes necessary to remove a nail, a nailer is used to do this by placing a bar under it.
12. To ensure high-quality fixation, the nails must be clogged tightly.
13. If mounting is done on a metal crate, self-tapping screws should be used. Initially, the sheets are fixed from both sides along the edges, in the middle of the nail are nailed through the wave. To fasten the elements along one line, you need to apply a stretched cord.
14. Gutters are attached to the eaves. Sheets should extend beyond the edge of the cornice by 7 cm. To ensure protection from insect penetration, a ventilation comb is installed on the cornice.
15. On each wave of material, the skate is nailed to the frame bars using nails. The installation of this element begins on the side with which the sheets were laid.
16. For ventilation, an additional ridge element is required. When installing these parts, you should also take into account the direction of the windy flow. The connector is fastened with an overlap of 10-12 cm.
17. All joints must be treated with a sealing compound.
18. Ventilation can be provided with roof fans. They are mounted together with the onduline on each of its waves. The sheet located at the top of the structure must cover the base of the fan.
19. One of the required stages of work is the arrangement of the roof window. Its presence will allow to go out on the roof and will facilitate the arrival of natural light in the attic room. The window is fixed with nails on the joint with the sheets. Ondulin in the upper part of the opening must be located with an overlap on the opening.
20. The interface between the sheets and the wall is made using special elements called raindones. For the production of these parts, the same material is used as for the manufacture of ondulin.
21. In the place of joint it is necessary to lay insulation. For the fixing of the valley, an additional element of the crate is mounted, on top of which this part is mounted.
22. The docking area of ​​the wall and roof is covered with an apron, which is fixed to the sheets with nails. If gaps remain between the ridge or the cornice and the roofing material, they should be filled with a special filler.
23. If you need to bypass the pipe, you need to define its perimeter to properly cut the sheets. Then they cut out the required shape.
24. The process of adjacence of the onduline to the pipe assumes the same actions as the work on the organization of abutment to the wall.
25. After the installation is completed, the joints between the sheets on the roof must be isolated from the penetration of moisture. Manufacturers of ondulin have developed for this purpose self-adhesive tape onduffles. With its help, the insulation of the connection zone of the roofing window openings with the roof is also carried out. Onduflesh allows to solve two tasks: to protect the roof from the arrival of moisture and to give it a finished look.

1. Work on the installation of this material should be carried out at a temperature of -5 ° C. .. + 30 ° C.It is not recommended to perform any manipulations with the onduline under low temperature conditions, as it can damage the material.
2. Nails are used as fixing elements, which are specially designed for this material. One sheet consumes 20 nails - 10 units in the top and bottom.
3. When installing the skeleton skeleton, you need to be guided by the angle of inclination. If this figure does not exceed 10 °, then you can use a continuous crate of plywood sheets or OSB.
4. With a slope of 15 ° it is necessary to mount the frame from the beams, observing a step of 45 cm.
5. If the slope exceeds 15 °, then the distance between the beams should be increased to 60 cm.
6. When working with the onduline, care should be taken to avoid deformation of the material. Damaged sheets will not withstand temperature changes and cracks form on them.
7. During the installation, you can only move around the fixed material.
8. A wooden hacksaw is used to cut the sheets. Beforehand, the tool should be lubricated with oil, so that it does not get stuck in the sheet during the sawing process.
9. Ondulin favorably differs from other materials by the possibility of fragmentary repair. If the roof is damaged, you can remove the deformed sheets and replace them with new ones.
10. Due to its small mass, the ondulin can be mounted on top of the damaged material, which eliminates the need for dismantling.

Ondulin: installation instructions

The work begins with the installation of a curtain frame on the rafter system. In doing so, the following order of actions should be observed:

Care instructions

It is recommended that the ondulin coating be inspected annually for possible defects in order to notice and eliminate them in time. The most suitable time for this is late spring, when the snow cover comes down and the roof dries. Air temperature during this period does not rise to a high level, which positively affects the quality of materials. If insignificant cracks and chips are found on the roof, sealants or adhesive repair tapes are used to remove them. The work is done in the following order.

1. Initially, the damaged area should be cleaned of contaminants and wiped with gasoline or mineral spirits. It is recommended to do this with a cotton cloth.
2. The protective coating is then removed from the adhesive tape, after which it is applied to the damaged area. Cut it at a distance of 3-5 cm from the crack.
3. To achieve a more aesthetic appearance, the ribbon can be painted in the color of the roofing material.

In the presence of more serious defects, some parts of the roof are replaced with new elements. Due to the small weight of ondulin, this can be done without dismantling the previous coating. There are two ways of repair:

• with frame mounting;
• without planking.

The first method involves the installation of a new crate, which is packed on the roof in the longitudinal direction. This work is carried out taking into account the angle of inclination, as well as during the installation of the material. To install a new frame in the old crate, you need to drill holes. First of all, the bars are installed along the edges. To determine the bottom edge of the construction between the bars tied rope. In this case, the process of laying the roofing material does not differ from the usual installation technology.

The last option is to install sheets on the old material. The advantage of this method is the speed of work. However, it has drawbacks. One of them is the inability to provide ventilation. Also, when using this method, it is possible not to get the fastening elements into the frame. As a result, there will be holes in the new coating, through which moisture will flow under the roof.

From contaminations, the roof of the ondulin is cleaned only by means of brushes or brooms. Do not use metal tools for this purpose, such as a shovel. In this way, the coating can be damaged.

Conclusion

Ondulin is an innovative roofing material, which began to conquer the domestic construction market not so long ago. But thanks to a lot of advantages, it has already gained considerable popularity. Among the advantages are durability, aesthetics, resistance to atmospheric and chemical influences and ease of installation. The installation of this material is a task that even a novice master can master without qualified training.
