PROSOCO manufactures the R-GUARD FastFlash® Air & Waterproof Barrier System. The FastFlash® system helps Passive House professionals achieve their goal of maximum energy efficiency by stopping heating and cooling losses from air leaks through the building envelope.

The vapor-permeable, durable, continuous and seamless air and water barrier system seals off all the tiny holes, seams and gaps that let air leak in and out, carrying energy dollars with it, and stressing the HVAC system.

The result is a building envelope tight enough to help Seattle’s Passive House Mini-B earn Passive House Institute U.S. certification, confirmed by blower door testing.
