A sound and/or moisture barrier underlayment suited for use on a roof or floor surface to provide a substantially flat and level surface, comprises at least first and second strips of insulation membranes (10) laid down one next to the other in a coplanar relationship. The first and second strips (24, 26) have a thickness W1. An overlap joint (28) is provided between the first and second strips (24, 26). The overlap joint (28) has a thickness W2 substantially equal to or less than W1 to provide a free-bump transition between the first and second strips (24, 26) while preventing straight-through infiltration.
L'invention concerne une garniture faisant office de barrière contre le son et/ou l'humidité, destinée à être utilisée sur un toit ou la surface du sol pour fournir une surface de niveau sensiblement plane. Cette garniture comprend au moins une première et une seconde bande de membrane isolante (10) disposées côte à côte dans un même plan. Ces bandes (24, 26) ont une épaisseur W1. Un joint de recouvrement (28) est situé entre les bandes (24, 26). Ce joint de recouvrement (28) a une épaisseur W2 inférieure ou sensiblement égale à W1 pour fournir une transition sans bosses entre les bandes (24, 26) tout en évitant les infiltrations directes.
