PERM-A-BARRIER® VPL 50 Air Barrier
Permeable, liquid-applied air and water barrier
Construction projects can be thrown completely off track due to bad weather—adding more days to the schedule. With construction schedules becoming tighter, builders are looking for ways to avoid these costly delays. Through its unique formulation, PERM-A-BARRIER® VPL 50 air barrier both eliminates weather delays and drives down the cost of installing weather barriers. This novel solution creates a barrier against air infiltration and exfiltration, minimizing energy loss and condensation problems.

Products
- Product Name
- Description
- Key Benefits
- Applications Type
PERM-A-BARRIER® VPL 50 Membrane is a fluid applied, one component, STPE vapor permeable air and water barrier.
- Fire resistant
- Phthalate and Halogen-free-“green” and environmentally-friendly
- Air tight
- Vapor permeable
Building envelope
PERM-A-BARRIER® VPL 50RS Membrane is a fluid applied, one component, STPE vapor permeable air and water barrier.
- Fire resistant – meets NFPA 285 as part of various wall assemblies with foam plastic insulation
- Formulated without phthalates and halogens
- Air tight – designed to protect against air passage and associated energy losses. Meets ASTM E2357 standard
- Vapor permeable – minimizes moisture from being permanently trapped in the wall cavity by allowing the wall’s ability to “breathe” and dry
What is PERM-A-BARRIER® VPL 50 Wall Membrane?
Liquid-applied air barriers are faster to apply than traditional materials, but the material can wash off in the rain. GCP has addressed this problem with PERM-A-BARRIER® VPL 50 liquid-applied air barrier, an easy-to-install solution that resists water quickly after installation.
PERM-A-BARRIER® VPL 50 membrane enables contractors to complete projects faster by reducing rain delays. Additionally, total project costs are lower than competitive latex technologies, resulting in cost savings.
PERM-A-BARRIER® VPL 50 air barrier enhances energy efficiency, providing superior protection against air and water vapor. Ideal for projects requiring breathable characteristics, PERM-A-BARRIER® VPL 50 air barrier permits water vapor through that could otherwise condense in the wall, yet it is impermeable to liquid water, so it can act as a water drainage solution.
