In flat roofs with a high attic, with a rafter roof airspace temperature (attic) should be almost equal to the outside temperature. To make it possible, the air space of the flat roof must be adequately ventilated (supply and exhaust openings). …
The table lists the minimum thickness of thermal insulation for a flat roof according to the current thermal protection requirements for buildings. A Ceram rib-and-slab ceiling was adopted for the structural layer of the double-section roof, reinforced concrete slab and a wooden beam ceiling with a soffit. The types of ceilings selected for the analysis are present in buildings …
Bipartite roofs best protect residential interiors against excessive heat loss, moisture and overheating. They are recommended especially above rooms with water vapor pressure above 2130 Well. In double-section flat roofs, the air space above the insulated ceiling under the roofing structure has …
The flat roof protects the internal rooms of the building against rainfall and temperature changes, that is, the influence of the external climate. The flat roof consists of many layers with different functions. On the supporting structure (ceiling) there is often a vapor barrier (vapor barrier), then a thermal insulation layer (thermal insulation). Between …
