Description
Walther Strong Airtight Single-Sided Tape is engineered to create strong, durable airtight seals across a wide range of construction materials. Designed for sealing overlaps, joints, and penetrations in membranes and boards, it delivers dependable airtightness in loft conversions, extensions, garden rooms, and general building projects.
Constructed with high-spec PVA scrim reinforcement (not cloth based) and a highly flexible backing, this tape provides outstanding durability and tear resistance while remaining easy to handle on site. Its high performance adhesive delivers exceptional bond strength (30N/25mm) and adheres securely to surfaces where conventional tapes often fail.
With a temperature resistance range of -40°C to +80°C and a UV-stable formulation, it offers reliable long term performance in both internal and external environments.
