Product description:
Slow Expanding Pre-compressed Foam Tape made of impregnated permanently elastic fine cell soft polyurethane foam, which expands slowly and evenly to provide a seal against wind and driving rain. The product can bridge extreme joint tolerances, maintaining a seal against driving rain (600PA) when compressed to at least 33%. It is compatible with all current building and sealing materials.
Features：
●Weather seal for wind-driven rain
●Vapour diffusion permeable
●Good air-tightness if used compressed
●Seals against uneven surfaces
●No shrinkage or blow-out due to closed-cell breakage
●Acoustic and thermal insulation
