Self-Expanding Foam Sealing Tape

This self-expanding foam sealing tape is designed to seal joints and gaps around window and door frames, cladding and general building details. Once applied, it expands to fill the void, helping to block wind-driven rain, drafts and dust for a long-lasting, tidy finish.

Made from flexible polyurethane foam impregnated with a modified acrylic dispersion, the tape combines elasticity with reliable adhesion. Its breathable structure allows water vapour to pass from inside to outside, helping to reduce the risk of trapped moisture and condensation within the joint.

Ideal for refurbishment and new-build work, it can be used around frame perimeters, façade and cladding joints, and where services pass through walls or roofs. Choose the size that matches your gap before expansion, then allow time for the tape to expand and settle into place.

For best results, apply to clean, dry, sound surfaces and press firmly to ensure good contact. The expanding action helps compensate for minor irregularities, making it a practical option for achieving consistent weather sealing on a wide range of substrates.
