Description
VapourFlash Window Flashing Tape 100mm x 20m
VapourFlash Window Flashing Tape is a premium engineered weather barrier designed to create a durable, watertight seal around windows and doors. Manufactured with a high-performance acrylic adhesive and an easy-to-use dual-liner system, it delivers fast, accurate installation while helping protect the building envelope from water and air leakage.
Unlike traditional flashing products, VapourFlash remains vapour open, allowing trapped moisture to escape while preventing rain, wind and air infiltration. This helps reduce the risk of mould growth, condensation and timber rot while improving the thermal efficiency of residential and commercial buildings.
Whether you’re installing new windows or upgrading weatherproofing on a construction project, VapourFlash provides reliable long-term protection where it matters most.
Designed for Superior Window and Door Flashing
VapourFlash has been engineered specifically for flashing windows and doors that require extended coverage. Its premium acrylic adhesive provides outstanding adhesion to a wide range of building materials, while the dual-liner backing allows for easier positioning and precise application around corners and junctions.
The result is a continuous weather-resistant barrier that helps improve the overall integrity of the building envelope.
Suitable for:
- Residential window installations
- Commercial window installations
- Door flashing
- Renovation projects
- New home construction
- Modular buildings
