Abstract

L'invention concerne une membrane pare-vapeur, destinée à être utilisée pour augmenter l'étanchéité à l'air d'un bâtiment ou d'une pièce, comprenant une couche active présentant une perméabilité à la vapeur d'eau qui augmente avec l'humidité relative environnante, ladite couche active étant constituée d'une sous-couche centrale d'un copolymère statistique d'éthylène et d'alcool vinylique (EVOH), et de deux sous-couches extérieures de polyamide (PA), l'EVOH ayant une teneur en motifs éthylène supérieure à 32 % en moles, de préférence comprise entre 35 et 60 % en moles.
