Patent

CA 2496521

An integrated waterproofing and air/vapor barrier membrane is provided which comprises a preformed waterproofing or sealing material layer (1) covered on one face with a adherent impervious material (1), and on the other major face with an adherent porous support sheet (16). The waterproofing or sealing material layer can be covered on both sides with adherent support sheets. Heating of the barrier membrane allows self-adhesion to a surface on which it is applied after transudation of fusion of the sealing material through the support sheets.

La présente invention concerne une imperméabilité intégrée et une membrane barrière air/vapeur qui comprend une couche de matériau (1) étanchéifiant ou imperméabilisant recouverte sur une face d'un matériau adhésif (1) imperméable et sur l'autre face principale d'une feuille de support (16) poreuse adhésive. Cette couche de matériau étanchéifiant ou imperméabilisant peut être recouverte des deux côtés de feuilles de support adhésives. On peut autocoller cette membrane barrière à une surface en la chauffant, surface sur laquelle on applique cette membrane après la transsudation de la fusion du matériau d'étanchéité à travers les feuilles de support.
