RainScreen SA is a self-adhered Air Barrier (AB) Water Resistive Barrier (WRB) with built-in rainscreen drainage matrix.

As homeowners, facilities managers and building owners become more conscious of the need to conserve natural resources and protect structures—while also maintaining indoor air quality—air and vapor barriers will continue to play an important role.

Building designers across the U.S. would agree that it is crucial to select an appropriate weather (air, vapor, and water) resistant barrier in accordance to the standard code, to prevent water infiltration, and to control air leakage in a building envelope. 

Maybe it is a high-rise, high-profile commercial structure that serves as the headquarters for a multinational corporation with the company’s logo proudly attached to the top floor. Perhaps it is a massive warehouse that will serve as a critical distribution link for an e-commerce giant. No matter the end result, the design vision for any new building begins in the minds of its owner and the architect on the project. 

GCP Applied Technologies added two new products to its air barrier portfolio: PERM-A-BARRIER VPL 50RS and PERM-A-BARRIER VPS 30 membranes.

MemBrain helps keep walls dry all year-round, significantly lowering the health and structural risks associated with moisture and mold. 

Sequencing issues. Finger pointing. If you’re involved with the design or construction of exterior building envelopes you’ve experienced this before—either you’ve been called out by another sub or trade for damaging their work or perhaps you’ve been guilty of it yourself. 

As a field technician, I spend a large percentage of my time working with contractors. This involves attending preconstruction meetings, site visits and providing installation training on mock-ups. 

During the summer months, we usually put a layer of sunscreen on to protect our skin from damage and burns, which can contribute to skin cancer. But why do we call it “sunscreen?”

It is important to establish a continuous air barrier for several reasons.
