Sofa for the roof is a facing panels that are designed to design horizontal surfaces. The front side is directed down. These products are used in the construction sector recently, however, they have already managed to get significant popularity.

Types of designs

Sophytes perform two tasks: give the building a more aesthetic appearance and provide ventilation effect, which prolongs the service life of the roof. The perforated structure of these products allows air to circulate freely.

Road ventilation allows you to achieve the correct functioning of the insulation. In the roofs of the attic type, it is located in the attic, in the attic structures, where the space between the elements of the rafter system fills. The insulation material misses the steam through itself, which comes from the inner and outdoor side of the building.

Sofits are divided into varieties depending on the material and method used to manufacture them. First consider types divided according to the first criterion:

1. Copper products are distinguished by the longest period of service. They retain their operational qualities for 150 years. Also among the advantages of sofits of this species, environmental safety can be distinguished, ease of care and protection against negative atmospheric factors.
2. Metal products are also practical and durable material. At the same time, they can be purchased at quite an acceptable value. Galvanized steel is used to produce such sofits.
3. The most popular today are aluminum sophistication. They acquired their popularity due to a number of advantages. These models are easily established, do not be temperature expansion, resistant to corrosive processes and fire, and also retain the appearance under the impact of ultraviolet rays.
4. Vinyl sofites are produced based on PVC. These products are available in a wide range, which allows you to choose them for any interior design. Finishing Sofitats from PVC today has been widespread. They differ available to the cost, resistant to the appearance of mold and fungal formations, have a small mass, withstand the temperature differences in the range from + 60 ° C to -50 ° C.

Depending on the features of operation distinguish the following types of soffits:

1. Solid unperforn panels. With their help, a solid branch of the cornice of sofit is performed.
2. Products having a partial perforation where the holes are located in the center of the panels. These sophytes can be called universal, because They are used to cover all sections. Their main advantage is effective ventilation, due to which these soffits are able to prevent the formation of mold.
3. Fully perforated panels. They are used for registration of protruding parts. The installation of these products will allow you to air all the inner elements of the roof.

How to calculate the number of panels

Before installing Sofita, you need to determine the amount of material that will be required to work:

1. Ventilation holes should occupy 1/150 part from the surface of the entire ventilated space. The area that needs ventilation is divided by the number 150.
2. Next from the resulting indicator, existing ventilation elements take out. It can be a tile with ventilation holes or auditory window openings. The result must be compared with perforation sofits.
3. Then the area is determined, which is taken as a result of the installation one panel. After that, the required number of products is calculated.

Criterias of choice

Sofits are used in the construction of new buildings, as well as in the process of restoring and updating the already built home. In the presence of protruding parts of the roof, such as fronts, visors, skates, sinks or eaves, you should choose perforated sofa, which can be studied in construction logs. They transform the structure will give it a complete appearance and protect against the aggressive influence of external factors.

For finishing works indoors, products are selected without perforation. As for the color scheme, here you can rely on your own preferences. According to experts, sophifes that contrast with the color of the house are most attractive.

Installing sofhs with your own hands

Installation involves the fastening of two parallel profiles, one of them is fixed to the wall, the second - on the sink of the roof. When installing, three species profile guide are used:

1. The n-profile element is used when attaching panels in angular parts.
2. With the help of the F-profile, the sofa is fixed to the wall.
3. The profile part j has universal qualities.

Roofing Svet can be open or closed. A distinctive feature of the first option is the lack of coating. The task of the sink consists in lengthening the rafter element. They are fixed to the rafter foot and focus on the wall, resulting in a triangle. It is attached to him.

Out of a closed type in the bottom of the wooden boards. When using vinyl sofits instead of wood, it is recommended to use vinyl. But this is possible if the panels are installed at the construction stage. If the house has already been erected, when installing sofits, they are fixed to the boards.

Products are recommended to be installed at the final stage of the installation of siding. The most suitable is the moment before fastening the last panel with the croups. This will correctly determine the parameters of the final board and the angular profile. Further actions are performed in such a sequence:

1. Installation starts from cutting the required sample sizes. At the same time, two gaps are left. For cutting use a circular saw or scissors for metal. This work cannot be searched without protective glasses. Cutting start in the fastener area.
2. Before mounting, first determine the starting point. Then 77 mm retreat from this place and designated the horizontal line in the perimeter.
3. Under it, the first panel is installed. One edge of the sofit is placed in the receiving profile on the wall, the second will start in the opposite profile element.
4. To facilitate the procedure for placing a panel in a gutter, it is shortened, it was for this that the gaps were envisaged.
5. Then the second sofit is introduced into the receiving item and is combined with the first element in the lock.

During this process, if necessary, bend the exterior bar profiles. But it is not necessary to apply great efforts. Since the profile may not return to its original position. There is another option to install sofit, which does not provide them with mounting to the receiving profile. In addition, sophisticated panels are inserted into it and snap them. Only after that the profile element is fixed.

Before you need to be sophisticated with the way. There are two options:

• under oblique angle;
• at right angles.

The first method provides for the installation of the H-profile diagonally in the corner area. To do this, you can use two J-profiles, but they need to be located the sides to each other. To achieve the most attractive aesthetic effect, the sofa is cut into such a way as to place the central gutter in one line.

When connecting at right angles, the profiles that are located near the walls are prolonged to the location of the outer corners. J-profiles are installed on the adjoining sophilors. In the absence of an F-profile, it can be made from the profile element J. The nail bar is cut and every 30 cm flex.

In some cases, the laying of sofites is carried out in the direction of the beams of overlapping the structure. In this situation, it is necessary to install the cerebral frame across the beam parts. For this purpose, use a cutting board or bars. When perpendicular to laying, the sofa can be recorded directly to the beams, but provided that the distance separating their distance does not exceed 50 cm. Otherwise, the preliminary installation of the crates, the elements of which are mounted perpendicular to beams. After that, parallel to the beam elements is mounted counter doom. The panels are fixed to the frame elements using self-tapping screws.

Recommendations

In order for the installation of sofita to be performed qualitatively, some rules should be followed:

1. In the process of storage of sofits, the sun rays fall on them.
2. When transporting packaging with the material must be on a flat surface.
3. When attaching, it is impossible to provide excessive pressure on the locks. Sofit should not be tightly adjacent to the fastening element, the gap is necessarily left between them.
4. The angles should not be treated with a sealing agent.
5. Excluded anti-corrosion screws or nails are used to work with sofits or nails.
6. Installation is carried out by fasteners of a certain size. The diameter of the cap should be 8 mm or more, legs - 3 mm.
7. Staples are widely selected, as the panels need to create conditions for free movement.
8. There is 1 mm space between the surface of the sint and fastener.
9. The fixing elements have apart from each other at a distance of 40 cm. The mount is performed at a right angle.

Conclusion

The appointment of sofites is to decorative decoration of certain parts of the roof, as well as to ensure ventilation at home. Their use allows you to increase the period of operation of the building. Syding panels Sofita differ in the application area. With the help of these elements, the surfaces are drawn up, the front side of which is facing in the lower direction.
