Laminated, thermal insulation panel
First Claim
1. A laminated, thermal insulation panel comprising:
- a board made of expanded polystyrene permeable to water vapor;
a membrane laminated over one side of the polystyrene board, said membrane presenting imperviousness to air and moisture and being permeable to water vapor; and
an adhesive applied between said membrane and board for laminating said membrane on said one side of the polystyrene board, said adhesive being applied in a pattern to ensure permeability to water vapor and being compatible with both the polystyrene of the board and the material constituting the membrane, so that the adhesive does not chemically attack the board polystyrene and the membrane material whereby the water vapor permeability of the board polystyrene and of the membrane material as well as the air/moisture imperviousness of the membrane material are not affected by the adhesive.

Abstract
A laminated, thermal insulation panel comprises a board made of expanded, molded polystyrene, and a membrane laminated on one side of the polystyrene board by means of an adhesive. The board and membrane are both permeable to water vapor, but the membrane is also impervious to air and moisture. The adhesive is applied under the form of strips and presents permeability to water vapor while being compatible with both the board polystyrene and the membrane material. Accordingly, the adhesive does not chemically attack the polystyrene and membrane material, whereby the water vapor permeability and air/moisture imperviousness of the latter are not affected. It can be appreciated that the resulting insulation panel is impervious to air and moisture from the outside but is permeable to water vapor from the inside. The joints between adjacent, laminated insulation panels are sealed by means of an adhesive tape applied on the membranes of the adjacent panels.

12. A method of thermally insulating the exterior walls of a construction, such as a residential house, comprising the steps of:
-
in-plant manufacturing laminated, thermal insulation panels each obtained by laminating a membrane over one side of a board made of expanded polystyrene, said board and membrane being both permeable to water vapor and said membrane being further impervious to air and moisture; covering the outside of said walls with a plurality of said insulation panels with the membrane thereof at the exterior; and sealing the joints between adjacent ones of said covering panels with an adhesive tape impervious to air and moisture, said tape comprising an adhesive surface applied on the membranes of said adjacent panels. - View Dependent Claims (13, 14, 15, 16)
