Overview
The PERM-A-BARRIER® portfolio offers both permeable and non-permeable solutions to meet the range of factors on a given project, including regional climate, wall design, compatibility with other materials, insulation placement and interior conditions.
Our newest air barrier PERM-A-BARRIER® NPS and VPS 30 employs a primer-less, self-adhered application for easier installation that saves time and money on the job. Eliminates primer, often a hazardous chemical, from the job site.
PERM-A-BARRIER® portfolio
The PERM-A-BARRIER® portfolio provides watertight, airtight air barrier systems and full field technical support for flexibility and high-performance compatibility with a project's building envelope design. We offer a broad product range for any wall design or design requirement. Our air barrier membranes and accessories are designed to work together and are rigorously tested to meet building code requirements. The end result is a truly optimized wall design that's sustainable over time.

GCP (GCP) PERM-A-BARRIER® VPL 50RS UV STABLE Membrane is a fluid applied, one component, STPE (Silyl Terminated Polyether) vapor permeable air and water barrier. When applied to approved construction surfaces, PERM-A-BARRIER® VPL 50RS UV STABLE liquid is designed to cure and form a resilient, monolithic, fully bonded elastomeric sheet, and to create a continuous barrier against air infiltration and exfiltration, reducing associated energy loss and condensation problems.
- UV stable behind maximum 1 in. wide open joint rainscreen system; provides design flexibility
- Can be exposed for up to 12 months during construction
- Early wash-off resistance
- Can be applied to damp-to-touch surfaces that are free of liquid water
- Sprayer friendly formula requiring light spray equipment
