Walther Strong HD Aluminium Foil Tape is the ultimate choice for professional insulation and ductwork applications. It excels in sealing rigid foam boards, HVAC systems, and reinforced fibreglass duct boards, making it indispensable for loft conversions and other demanding environments.

The heavy-duty reflective foil layer provides a robust barrier against moisture, dust, and chemicals, ensuring long-term durability. Its thermally conductive properties enhance insulation performance, thus promoting energy efficiency. The tape features rolled edges and a tear-resistant design, making on-site handling seamless and efficient. Backed by a strong pressure-sensitive adhesive, it forms a secure, long-lasting vapour seal across a wide range of surfaces, helping to prevent cold bridging on PIR boards. With Class 0 flame resistance and excellent moisture and chemical resistance, this tape offers a professional-grade, reliable solution for high-performance insulation and duct sealing needs.
