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.
