In cottage construction, mainly a pitched roof is used. With the «cold roof» version, when a non -residential unheated attic is located under it, the floor of the attic is insulated. When using a room under the roof — attic — as a residential, it should be provided in the heating system (heat from the lower floors is usually not enough), and insulate the roof. If the attic is converted to housing after the installation of the main heating system, an infrared heater can be installed in it as a heating device. In this case, the “warm roof” option is used: the roof is insulated with special heat -insulating materials. The most applicable fiber-shaped insulation based on mineral (basalt) or eco-watu (cellulose or based on other. natural materials). To ensure fire resistance, the ecovatas are impregnated with special antipyis compounds. Thermal insulation in the form of mats or roller materials is laid on a crate or fixed between the rafters, and a layer of vapor barrier under it and waterproofing from above.
