| 摘要 |
<p>The invention relates to a multifunctional heat insulation system used for carrying out roofs and mansard-roofs of civil buildings and, depending on the constructive solution of the project, for the heat insulation of industrial buildings roofs, the system comprising two air layers which break the flux of convective heat transfer and give the phonic insulation a supplemental efficiency, the total thickness of this system being reduced to the half in comparison with the classic system. According to the invention, the insulation system comprises the following layers, presented from the exterior to the interior: the roof covering (1), a strip grid (2) with the role of supporting the roof covering, a diffusion membrane (3), an OSB-type insulating fiberboard or roof boarding (4), rafters (5), a mineral wool layer (6), cellulose, polyurethane foam or polystyrene, made tight with aluminium adhesive tape with a thickness greater than 5 cm, an air layer (7), a heat reflective insulation (8) which prevents the radiative heat transfer (11), a profile system (10) for fastening the gypsum board, the panelling or other covering elements, an air layer (9), a layer (13) made of gypsum boards, panelling or other covering elements, the air layers (7 and 9) determining the breaking of the flux of convective heat transfer (12).</p> |
