Description Walther Strong Airtight Double-Sided Tape provides a robust, concealed bonding solution for fixing vapour control layers (VCLs) and membranes directly to structural elements. Its discreet double-sided design makes it ideal where a clean, invisible airtight seal is required behind finishes. Engineered with high-spec PVA scrim reinforcement, this tape offers exceptional structural strength and dimensional stability. The high performance adhesive delivers strong adhesion (30N/25mm) to timber, metal, masonry, and membrane surfaces — ensuring a secure bond even where traditional tapes may struggle. With a temperature resistance range of -20°C to 80°C and UV stability, it performs reliably in demanding internal and external applications, making it ideal for professional membrane and VCL installations.
