PERM-A-BARRIER® VPS 30 reduces installation time by up to 35% compared to membranes requiring primer.
This durable, weather resistant film consists of a proprietary breathable carrier film with a specially designed adhesive. This unique membrane provides superior protection against water and air ingress. It increased an effective barrier against the air infiltration exfiltration associated with energy loss and condensation in the building envelope.
What is PERM-A-BARRIER® VPS 30 air barrier?
This sheet membrane is ideal for wall assemblies that require a breathable air barrier. It permits the diffusion of water vapor that might otherwise condense in the wall structure. The membrane is impermeable to water, enabling it to act as a water drainage plain.
- Fast application time
- Can be installed in wide temperature range (Down to 25° F/ - 3.9° C)
- Aggressively tight bond to substrate
- Easily repositionable before rolling
