tesa Foam Sealing Tape 4042448103000 – Gap Sealing Tape for 1–5 mm Joints
The tesa Foam Sealing Tape is a self-adhesive polyurethane foam tape designed to seal gaps and joints in building and construction applications. It provides a reliable barrier against air, dust, and moisture infiltration across a wide range of surfaces and substrates.
Seals gaps from 1 to 5 mm with compressible foam that adapts to uneven surfaces
Self-adhesive backing ensures quick, clean installation without additional fasteners
Polyurethane foam construction delivers long-term durability and weather resistance
Suitable for both indoor and outdoor building envelope applications
What sets the tesa Foam Sealing Tape apart
Unlike rigid sealing strips, the compressible foam core allows the tape to fill irregular gaps while maintaining consistent compression force. The UV-resistant formulation remains stable when exposed to outdoor conditions, making it a dependable choice for facades, windows, and structural joints where long-term seal integrity matters.
Ideal for...
Building contractors, facility maintenance teams, and DIY installers working on new construction or renovation projects. The tape is particularly suited for sealing joints in window frames, façade panels, insulation systems, and other building envelope components where a 1–5 mm gap needs a permanent, flexible seal.
Application of tesa Foam Sealing Tape
Clean the surface thoroughly — remove dust, grease, and loose particles from the gap or joint
Cut the tape to the required length, leaving a few centimetres of overlap at each end
Peel the backing film and press the tape firmly into the gap, ensuring full contact on both sides
Apply moderate pressure with a roller or flat tool to activate the adhesive and achieve a uniform seal
