WB 620 window sealing tape only one tape for internal and external sealing. According to the valid EnEV, all component joints in the heat-transferring perimeter surface of a building must be permanently sealed on the room side so that they are impermeable to air. DIN 4108-2 requires that the joint permeability of building components, expressed by the a-value, must not exceed the value of a <0.1 m³ [m h (daPa)²/³].
Can be painted/plastered over, dimensionally stable and fold-resistant, with self-adhesive on one side.
