Description

VapourFlash Engineered Weather Barrier features a premium acrylic adhesive and dual-liner system for fast, precise installation. Designed for flashing windows and doors requiring extended coverage, it creates a watertight, airtight seal while remaining vapour open, allowing trapped moisture to escape and reducing the risk of mould growth and timber rot. By sealing air leakage around critical junctions, VapourFlash also enhances the thermal efficiency and overall integrity of the building envelope.

VapourFlash is UV-stable, providing excellent resistance to prolonged exposure during construction while maintaining durability in demanding environments. VapourFlash can be pre-installed by window fabricators on aluminium fins or applied on-site as a superior alternative to traditional dampcourse, helping improve installation efficiency and weather-tightness around critical openings.
