The device of a roof. Rattan for metal tile

The lining for metal tiles is a bar, lying perpendicular to the rafter's legs. As a rule, the beams are nailed to the rafters with nails, the length of which is twice the thickness of the tree. Roof roofing allows you to evenly transfer weight and other loads to the structure. In its absence, the design will only be effective by half.

The casing under the metal tile is made, as a rule, continuous. It is laid out with a bar with a gap of a centimeter. The continuous crate for metal tiles is suitable for asbestos-free or asbestos - cement flat slate, and for soft tiles. In this case, it must be arranged at the intersections of skates (skates, valleys, ribs), as well as at the eaves of the cornices.

The curb under the metal tile is a necessary detail of the structure. The rafters are fixed stably and have a pitch of 0.6 meters. The boards must be treated with an antiseptic. If necessary, use an antiseptic bar. In addition, experts recommend the use of anti-condensation film.

If in the construction plan there is a thermal insulation (for example, in the attic), then a film is required to prevent penetration of moisture and blowing of the insulation. In the absence of film rafters and lathing under the metal tile will be ventilated quite freely.

The film must be laid from the bottom of the roof over the rafters with horizontal stripes. At the same time, you must make an overlap of fifteen centimeters. It is not necessary to stretch the film. It is allowed to sag by two centimeters. The laid out film is fixed along the rafters with a falling beam. In this case, the beam has a thickness of less than three centimeters, and in the section along the width is equal to the width of the rafter. After the laying of the film, the lathing under the metal tile is laid. If the design of the film is not provided, then the boards are laid directly on the rafters.

Horizontal boards for the crate must be all antiseptic. Their cross section is from 2.5 to 3 centimeters per meter and a half. To equip the structure it is allowed to use any inch, but all boards should have the same thickness. Correctly selected boards will ensure a flat plane of the roof. It should be remembered that the lowest of them should have a thickness that is one and a half centimeters thicker than the other boards. The end bar must always be higher than the rest of the structure.

On both edges of the ridge of the ridge, experts recommend fixing two boards in addition. In this case, the ridge board will be securely fastened.

The first board is fixed at the bottom of the rafters in two places with the help of screws or nails. The boards are arranged in steps equal to the step of the wave of the metal tile. So fastening the sheets of coating will not be difficult. As a rule, the step of the battens is 35-40 centimeters, but it is better to find out the pitch of the material in advance.

Correctly assembled control box and equipped lath will significantly reduce the penetration of noise that occurs when rain or other atmospheric phenomena.
