Soudal SWS Universal Inside Tape – 100 mm

Professional airtight sealing. Flexible installation. Designed for warm window installation systems.

The Soudal SWS Universal Inside Tape (100 mm) is a high-performance vapor-tight sealing tape used in warm window installation systems (SWS – Soudal Window System). It provides an airtight barrier on the interior side of the joint between the window frame and wall, preventing moisture diffusion from inside the building into the insulation layer.

Thanks to its flexible material and strong acrylic adhesive, the tape ensures excellent adhesion to a variety of substrates — including PVC, concrete, brick, plaster, and metal. It can be plastered, painted, or covered with finishing materials, making it ideal for both new builds and renovation projects.
