Tescon Extoseal 150mm x 20m Roll

Tescon Extoseal is a high-performance airtight tape designed for sealing external wall connections and joints in building construction. This 150mm wide roll provides 20 metres of coverage, making it ideal for large-scale projects. The tape features a robust adhesive backing that bonds securely to most building substrates, creating a reliable air barrier that helps improve thermal performance and reduce energy loss. Its flexibility allows it to accommodate minor movement in building materials without compromising the seal. Tescon Extoseal is commonly used to seal window and door frames, wall transitions, and other critical junctions where air infiltration must be prevented. The wide format minimises the number of seams required, streamlining installation on expansive surfaces. Suitable for both internal and external applications, this tape supports modern building standards for airtightness and weatherproofing. Store in cool, dry conditions before use.
