Patent

CA 2215502

The invention relates to a vapour barrier for use in the heat insulation of buildings, which can be particularly used for heat insulation measures in new buildings or in the renovation of old buildings. The vapour barrier according to the invention is here in a position to effect water vapour diffusion under different environmental conditions. This is achieved by a material being used as the essential material which has a water vapour diffusion resistance dependent on the ambient humidity and in addition has adequate tensile strength and tear resistance.

L'invention concerne une barrière de vapeur servant à isoler des bâtiments contre les effets de la chaleur, pouvant notamment s'utiliser dans des constructions neuves ou pour rénover des bâtiments anciens. Cette barrière de vapeur est de ce fait à même d'assurer l'échange de vapeur d'eau dans différentes conditions environnementales. Le principal matériau employé est un matériau qui présente une résistance à la diffusion de la vapeur d'eau dépendant de l'humidité ambiante et résiste par ailleurs suffisamment à la traction et à la déchirure.
