High Performance Flexible Self-adhesive Flashing Tape
Tyvek® FlexWrap flashing tape works seamlessly with Tyvek® and AirGuard® products to help you create continuous airtight and watertight seals.
For all those tricky jobs, Tyvek® FlexWrap tape will keep leaks and gaps at bay. Ideal for both internal and external use, this “magic” tape makes light work of sealing windows, chimney breasts, pipe penetrations and other custom shapes, ensuring air-tight and water-tight protection when you need it most.
Short on time? Not a problem. The Tyvek® FlexWrap tapes get the job done 50% faster than standard tapes and seals, and require no additional fixings. The durable Tyvek® top sheet will adapt itself to structural movements.
Tyvek® FlexWrap is compatible with a huge choice of building materials and will adapt to common and uncommon shapes from windows to chimney breasts, creating a water-tight and air-tight seal that will withstand the elements.

Installation of Tyvek® FlexWrap tapes:
The surface must be free from dirt, moisture, ice, grease and other materials which could reduce the adhesion. Tyvek® FlexWrap is to be installed when dry and at temperatures above 0 °C. A primer may be used for application temperatures below 0 °C and non-ideal surface conditions.
• Properly position Tyvek® FlexWrap around the surface to seal.
• Minimise wrinkles and bubbles by smoothing the surface and by repositioning as necessary.
• Apply pressure by hand along the entire surface to achieve a good bond to the substrate. (After pressure has been applied repositioning may be difficult.)
• After completion of the installation Tyvek® FlexWrap has to be covered within 4 months with the appropriate building materials.
