Unlike conventional tiles, the metal has more than 5 times smaller mass and larger area, due to this, it is possible to use lightweight load -bearing structures, rafters, crate.
Today, this roofing material is available to most developers, but with independent laying, strict implementation of installation technology is required. Due to the big difference between the external and internal temperature on the inner surface of the tile, condensation is possible. This is fraught with the occurrence of corrosive processes or decay of the elements of the roof, which can lead to the destruction of the entire roof. To prevent this process, in the installation of a roof from metal tiles, special materials called anticodandate membranes are used. This material is one -sided, works in one direction, so it must be laid with a rough side to the insulation. The optimal ventilation of the insulated roof should be provided with two air gaps, which are usually formed with the help of a crate and counterparty. By the way, the thickness of the applied insulation is determined by special calculations that take into account the climatic features of the area.
If the roof is planned not insulated, and the operation of the attic is not required (the so -called cold roof) installation is carried out using the following technology. The crate, standard or continuous, directly on which the metal tile is mounted on the rafters. Remember, trimming metal tiles is allowed only specially designed for cutting metal with scissors. Bulgarian leads to combustion of a protective coating in the Reza area.
