PERM-A-BARRIER® air barrier system
A comprehensive portfolio of fully-bonded air barrier membranes for NFPA 285 compliant assemblies. GCP technology includes permeable and non-permeable solutions offered as both fluid-applied and sheet-applied systems.
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. 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.
- Product Name
- Key Benefits
- Applications Type
PERM-A-BARRIER® VPL 50 is a fluid applied, one component, STPE membrane that cures to form a resilient, monolithic, fully bonded elastomeric sheet when applied to construction surfaces. PERM-A-BARRIER® VPL 50 membrane is vapor permeable for wall assemblies requiring this “breathable” characteristic. As a vapor permeable membrane, it permits the transfusion of water vapor that may otherwise condense in the wall structure; but is impermeable to liquid water, which allows the material to act as a water drainage plain.
- Resistant to early rain
- Simple application
- Chemical cure, wet thickness is equal to dry thickness
- STPE technology
Design versatility and performance
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 employs a primer-less, self-adhered application for easier installation that saves time and money on the job. Eliminates primer, oftentimes a hazardous chemical, from the job site.

Tried and tested for high performance with code compliance
Most products in the PERM-A-BARRIER® portfolio meet or exceed all ASTM, ABAA, and NFPA building code standards. In addition, PERM-A-BARRIER® solutions have been tried, tested, and proven across thousands of projects worldwide.
Expert field technical support
Our technical experts frequently provide direct consultation throughout the design, product selection and installation process. In addition to project specific support, GCP provides both classroom and hands-on applicator training to ensure that our PERM-A-BARRIER® products are installed correctly and perform as designed - protecting the structure for years to come. Able to instruct applicators on the installation of sheet membranes and proper spray techniques, GCP field technicians advise on the proper sequencing and use of materials within these flexible systems. Consult in product compatibility, assembly techniques for a completely water and air tight system. Offer advice on; detailing, sequencing, efficient assembly techniques, labor saving tips.
