PERM-A-BARRIER® Aluminium Flashing
Verified by manufacturer 1 month ago
Self-adhesive air and vapour barrier sealing membrane.
Application
For air and vapour barriers. Can be used in cavity or vertical wall construction where extended UV exposure is required (up to one-year).
Description
Self-adhesive sealing membrane for protecting and sealing critical areas of the building superstructure from the damaging effects of the elements. Minimizes air and water vapour flow through the building exterior at transition areas to provide a continuous air barrier and prevent premature deterioration of the building envelope.
Features and benefits:
- Transmits wind loads directly to the substrate.
- Impermeable to the passage of liquid water and water vapour.
- Provides extended UV exposure.
- Improved sealant adhesion to film.
- Dimensional stability.
- High tear strength.
- Puncture and impact resistance.
- No flame hazard; self-adhesive overlaps ensure continuity.
- Accommodates minor settlement and shrinkage movement.
- Factory made sheet ensures constant.
- Non-variable site application.
- Allows self-sealing around mechanical fasteners.
- Wide application window.
