Most of the owners of country houses would like to relax in it not only on warm summer days, but also in the winter. For this, it is necessary to create certain conditions here, the main of which is to provide heat in the house. In this case, the question immediately arises: how to warm the roof ? Because it is through the roof that the greatest heat losses occur. To solve this problem, you can use various combinations of different materials that will ensure its durability, as well as a decrease in the level of heat loss. For this purpose, you can use the “insulation pie”, which consists of a large number of layers of various materials. A mineral wool insulation is used here, moisture and windproof membrane, as well as foamed polyethylene, which acts as a polarizer. In order not to increase the mass of the entire roof structure, it is possible to use mineral wools to ensure effective thermal insulation. This material has good thermal insulation properties and belongs to the class of fibrous insulating materials.
Solution of the issue: how to warm the roof, consists in laying the insulation between the rafters. At the same time, you should not save on its thickness, otherwise insulation may be insufficient. Due to the fact that the roofing structure is very susceptible to external exposure, mineral wool insulation should be equipped with hydraulic and vapor barrier, which will prevent its premature destruction. For this purpose, hydraulic and windproof membranes are used. These membranes are non -woven materials created from synthetic fibers. These materials must be laid on the insulation perpendicular to the slope of the roof. Moreover, it is necessary to do this so that a certain overlap of the upper canvas on the lower forms is formed and is 100 mm. This membrane for mineral wool materials provides protection against wind, and also makes heat loss through the roof less significant.
For those who worry about the question of how to insulate the roof, it is important to know that the formation of condensate on the cold parts of this “pie” is caused by the temperature difference existing here. If you want to avoid its occurrence on the inner surface of the insulation, you will need foamed polyethylene. Its closed cellular structure makes it an excellent thermal insulation material. This material can be glued and easily give it the desired shape. That is why, for thermal insulation of complex surfaces, foamylers are used precisely. With the help of this material, several issues are resolved at once: hydrolya, sound and thermal insulation. Foamopylene, in the form of prepared paintings, is fixed by a construction stapler at the very base of the roof structure. At the same time, individual canvases of this material can be laid both in the joint and in the overlap. At the same time, in order to ensure the desired level of water and vapor barrier, it is necessary to use a double -sided tape at the joints. To ensure air circulation and the output of water vapor, it is customary to leave a certain gap between the foam polyethylene and finishing material with a size of 15-20 mm.
