Abstract
L’invention concerne un procédé d’amélioration de l’étanchéité à l’air d’un bâtiment ou d’une pièce d’un bâtiment comprenant l’application d’une membrane pare-vapeur sur la face interne des murs dudit bâtiment ou de ladite pièce d’un bâtiment, caractérisé par le fait que la membrane pare-vapeur est une membrane hygrorégulante comprenant une partie active comportant - une couche médiane d’une épaisseur comprise entre 2 µm et 200 µm, de préférence entre 4 µm et 100 µm, constituée d’un biopolymère ayant un coefficient de perméabilité à la vapeur d’eau P1 qui augmente avec l’humidité relative moyenne et qui, lorsqu’il est déterminé à 23 °C et à une humidité relative moyenne de 25,5%, est au moins égal à 300 Barrers, et, de part et d’autre de la couche médiane et de préférence en contact avec celle-ci, - deux couches externes d’une épaisseur comprise entre 100 nm et 20 µm, de préférence entre 200 nm et 2,5 µm, constituées indépendamment l’une de l’autre d’un polymère organique présentant un coefficient de perméabilité à la vapeur d’eau P2, déterminé à 23 °C et à une humidité relative moyenne de 25,5 %, au plus égal à 250 Barrers, de préférence compris entre 0,05 et 100 Barrers, en particulier entre 1,0 et 20 Barrers.
