Adhere a composite facer to at least one, preferably both, primary surfaces of a foam panel or board to impart a combination of enhanced strength and long term thermal resistance to an insulating foam board. The composite facer includes a foam contact layer that provides strength, low elongation and abuse resistance and a barrier layer with low oxygen permeability.
L'invention concerne le collage d'une surface de contact composite sur au moins une, de préférence deux, surfaces primaires d'un panneau ou d'un bloc de mousse afin de doter un panneau en mousse isolant d'une solidité améliorée et d'une résistance thermique à long terme. La surface de contact composite comprend une couche de contact en mousse assurant une solidité, un faible allongement et une résistance à l'utilisation incorrecte, et une couche barrière à faible perméabilité à l'oxygène.
