Energy conservation when heating your home largely depends on the arrangement of the roof and windows. Therefore, it is important to take into account the thermal insulation properties of window structures and the designed roof in order to provide comfortable conditions in the premises without excessive heating costs.
It is known that warm air rises up, so in a 2-story cottage, especially, in the presence of an open staircase with a stairs to the upper floor, the heat of the first floor will be distributed upward, heating the second floor. Moreover, with poor roof thermal insulation, heat loss of the house increases significantly.
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.
With reducing heat loss through the roof, the energy consumption for heating the attic is not large.
