Description

Ensure a durable and airtight building envelope with Tesa Sealflex+ Building Sealing Tape 50mm x 25m. This flexible, PE-based sealing tape is specifically engineered for professional, airtight sealing of overlapping vapor barrier and vapor retarder films. Featuring an extremely high and long-lasting adhesive strength, it effectively protects building structures against moisture, draughts, and energy loss.

Engineered for Tough Environments and Pipe Penetrations

Beyond sealing foil overlaps, Tesa Sealflex+ is a highly reliable solution for sealing complex wall and ceiling penetrations, such as electrical cables, conduit pipes, and ventilation ducts.
