New Air Barriers Provide Superior Protection Against Building Ingress

By GCP Applied Technologies.

These resilient air barrier membranes reduce energy loss and can be installed in cold temperatures.

On September 9, 2020 GCP Applied Technologies introduced two new air barrier products to their already extensive list of construction products:  PERM-A-BARRIER® VPL 50RS and  PERM-A-BARRIER® VPS 30 membranes.

GCP Applied Technologies is a leading global provider of construction products technologies. The new air barriers have been designed specifically for exceptional protection against the damaging effects of air and liquid water ingress on building structures. Additionally, they reduce energy loss and condensation problems throughout the building where the membranes are applied.

The PERM-A-BARRIER® VPL 50RS membrane is a fluid applied, single component, one coat application STPE vapor permeable air and water barrier. One of the most sprayable liquid STPE applied air barriers on the market, PERM-A-BARRIER® VPL 50RS membrane can be applied by rolling or by spray application. It is also rain resistant and can be installed in the most uncertain weather conditions, including temperatures down to 25° F. When applied to approved construction surfaces, this air barrier cures and forms a resilient, monolithic, fully bonded elastomeric sheet to create a continuous barrier. 

The PERM-A-BARRIER® VPS 30 air barrier is a primerless, vapor permeable air and water barrier consisting of a proprietary breathable carrier film with a specially designed adhesive. This unique membrane reduces installation time up to 35% compared to membranes requiring primer. Its advanced permeable adhesive technology creates an aggressive tight bond to the substrate, providing an effective barrier against the elements. PERM-A-BARRIER® VPS 30 also has a durable weather resistant film and superior adhesion when applied in cold temperatures.                    

The PERM-A-BARRIER® VPS 30 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 also act as a water drainage plain.                       

The addition of PERM-A-BARRIER® VPL 50R and PERM-A-BARRIER® VPS 30 membranes further strengthens GCP’s PERM-A-BARRIER®  air barrier portfolio. As with all GCP’s air barrier products, they are tested to the most stringent industry standards. GCP goes beyond providing just products; it brings technology, service, and expertise together to help customers grow their business.
