The Walther Strong HD Aluminium Foil Tape is an essential tool for professional insulation and ductwork tasks, adept at sealing rigid foam boards, HVAC systems, and vapour sealing reinforced fibreglass duct boards.

It is particularly effective for preventing cold bridging on PIR boards, making it highly suitable for loft conversions and other challenging environments. This heavy-duty tape features a reflective foil layer that acts as a barrier against moisture, dust, and chemicals, ensuring long-term durability and protection. The tape's rolled edges and tear-resistant design facilitate ease of handling on site, ensuring intact installation. The thermally conductive aluminium enhances insulation performance, promoting energy efficiency. Equipped with a strong pressure-sensitive adhesive, it provides a secure, long-lasting vapour seal across various surfaces and tears cleanly from the roll to minimise waste, thus saving installation time. With Class 0 flame resistance and excellent resistance to moisture and chemicals, it presents a professional-grade solution for high-performance insulation and duct sealing needs. It delivers sustained protection, improved energy efficiency, and easy on-site handling, making it the preferred choice for professional installers.
