The final step when installing the roof of the house is the stitching of its soles. Svet is called part of the roof, which goes beyond the boundaries of the walls. Make it to protect the walls and foundations from atmospheric precipitation. The roof fusion is carried out at the very last moment after the installation of the drainage. Installation of elements of the binder will solve several tasks. First, such a design will block the penetration of ascending flows under the roof during a strong wind. Often such streams with very strong wind become the cause of the destruction of the roof design. Secondly, the entry will be able to hide from extraneous eyes all the "latter" of the roofing structure: rafters, waterproofing, vaporizolation, etc., making an appearance at home more respectable.

For firmware, the roofing houses around the entire perimeter uses soffits. How to make the installation of sofes with your own hands - further in the article.
What is sofa and what they are manufactured
Sofits are called the panels that are sewn the roof edge throughout the perimeter. Depending on the installation site, they are:
- Eaves. Such sophies cover the space between the lower sink and the house wall. Farmers play a big role in the "ventilation" of roofing pie. Ascending flows of air to a certain extent should pass along the rafted to the roof of the roof, providing natural ventilation of the roofing system. Without this, there is a big risk of damage to the wood of the rafter system, which will lead to the early way out of it. That is why it is impossible to sew tightly stern. If you leave it not fed, then, in addition to a strong wind, which can simply raise the roof, the birds or bats can be penetrated under the eaves, which to deliver a lot of trouble. To solve the cornice binder problem, experts recommend using perforated sophytes for this work. They are a panel with many holes. Installing them in alternating with a deaf material, you can adjust the locations and the intensity of the dosage of the air. Some manufacturers produce combined soffits. Such a panel is conditionally divided into 3 parts, the extreme of which is deaf, and the average is perforated.
- Fronton. Fronton Svet is not involved in the ventilation system. On the contrary, the fronton is not protected by no plane from atmospheric precipitation. That is why there is a solid (deaf model) that will protect rafters and other elements of the roof from moisture, ensuring the waterproofability of the structure.
Modern sophytes are made of wear-resistant materials, such as plastic, vinyl, aluminum, galvanized steel and copper.
- Plastic or vinyl is distinguished by a long service life and a wide palette of colors. Thanks to this, such panels can be easily selected under the color of siding to get a holistic picture of the exterior finish at home. Plastic, as the vinyl, waterproof, so such a material is perfect for the finishing of the front-bottom sweep, they do not fade in the sun and are easily installed without a large amount of waste. These panels are not too expensive, which positively affects the general estimate of roofing work. However, plastic models have their drawbacks. First, they support the burning very well, and secondly, they have a high expansion coefficient that, with incorrect installation and increasing the temperature, it can lead to a "swelling" of the material.
- Aluminum soffits. It is made of thin aluminum sheet by stamping and are coated with a special anti-corrosion composition, which allows them to serve for a long time. Unlike plastic or vinyl, aluminum is more environmentally friendly, it is not afraid of open fire, however, its cost is much higher and the installation process is somewhat harder. It is especially worth noting the low coefficient of expansion of aluminum sheets in comparison with plastic or vinyl. Due to this, when applying such sofits, see the waviness of the plane with an increase in temperature is almost unrealistic.
- Cink Steel. Used as a budget option. It is much lower than plastic and aluminum. However, there is much greater weight and relatively short service life. Installation of metal sofites is a bit more complicated than plastic products.
- Copper. Such material for the production of sofit on the roof end is quite rare. The reason for this is its high cost. In addition, copper is a rather soft material, which at high loads can simply deform.
Installing aluminum soffits
Installation of aluminum sophytes is not a bit too complicated, but requiring attention and certain skills. In principle, such work is not particularly different from the installation of plastic panels.
The options for mounting sofits on the roof are somewhat, and depend on the distance from the end of the rafter to the wall of the house.
- If this distance is less than 400 mm, then the sofit starts into the guide profile at the ends of the rafted and the wall of the house. At the same time, no additional attachment is required.
- In the event that this distance is more than 400 mm, but less than 500 mm, along the perimeter of the roof at the ends of the rafter is installed by the roach rail, to which J-philo is attached. The rail serves as an extra place for fastening Sofita.
- If the distance is more than 500 mm, then the timber is installed between each rafter and the wall. Further along this design throughout the perimeter of the building, a bacheaker is installed for fastening sofit.
Procedure for work:
- Before starting work, it is necessary to thoroughly measure all the roof parameters and make a scheme. This will help to plan the amount of material for purchases, so as not to buy extra, because aluminum soffits are not cheap.
- First of all, it is necessary to establish a profile. J-profile, or, as it is also called - the starting profile, attached to the rafters. In order to attach it to the end of the rafted rafter at the right angle, the lattes are cut into such a way that their end is perpendicular to the wall of the house. The profile is attached with the help of self-tapping screws. Fasteners must be stainless steel. Otherwise, from the impact of moisture, it will begin to rust, which may cause rafted rotation. In the corners of the building, connective angular profiles are installed. They are attached to a specially installed timber. Installation of sofit in corners often causes the misfortune of beginner masters. However, if everyone is careful and carefully, there should be no problems.
- By installing the J-profile and receiving, you can start mounting the panels themselves. Before that, they must be cut on measuring lengths. The length of each panel should be equal to the distance between the edges of the profile minus the technological gap, which for aluminum sofites is 6 mm.
- After the panels are cut, they can be installed. Due to the fact that they are cut with a technological gap, they are installed easily. After installing the first sofit panel, it must be attached to the crate with the help of self-tapping screws. Usually for this use self-tapping screws for steel plasterboard profiles (in the people - seeds). One of the ends of the panel is made specifically for fastening it to the base. After fixing the first panel, the second starts in profiles, as well as "in the castle" from the first, slightly pulls up so that the castle stretches, and is attached to the crate. Thus, the entire perimeter of the cornese swell is trimmed.
- Installation on the J-Fack. This installation is made in the case when a headile board is installed in the end of the rafter system. The J-Fack is a wide profile, the end of which has a groove to install sofit. The width of this profile is equal to the width of the frontal board. The last profile is fastened with galvanized screws.
FRONTONOON FRONTON SOFITS
For the binder of the frontal soles, deaf sofa are applied. The process of installation of panels is practically no different from the cornese sweep. The j-cham chamfer is fastened to the front board. Then, three vehicles are used to the bars of the roof crates for fastening sofit planks. A j-profile is attached to the first from the wall of Brus. In the future, the process of firmware is repeated by the same technology as the eaves.
Basic Errors when binder Correspond's Sofitam
Very often, when it would seem, a simple task, a small deviation from the production technology of work can entail unpleasant consequences:
- Disregarding additional fastening. Often the masters are negotiated by the rule of the fastener installation. This is done in order to save money and time to install the crate. However, soon due to the gusts of the wind, Sofita Planck can play, which will lead to its destruction. It is better not to save on additional fasteners.
- Installation of sofits for roofing to the skin of the house siding and installation of drainage. After the clamping is installed, perform finishing with siding and the installation of drainage, it will be problematic, which is why the installation of sofits is worth producing at the very last moment.
- The use of ordinary fasteners. The whole fastener, which is used in the installation of sofits to cover the roof, should be stainless steel. Otherwise, rust is transferred both on the sofit panel and on wood.
- When installing plastic panels, the technological gap is not withstanding. Plastic has a large expansion coefficient, so in the summer, when heated Sofita, he needs a space for expansion. Otherwise, it will simply lead.
