Tighter than tight: Fensterflex Inside Alu

With an SD value of >1500, it is our most vapour diffusion-tight film tape for bridging the joint between window and building in the interior. Due to its formability and foldability, it is ideal for corners and joints and impresses with its very good sealing and adhesive properties.
