Aero-Block SA

Aero-Block SA is a pre-fabricated, self-adhering air, vapor, and water barrier membrane. It is composed of a durable, multi-layer polymer film that is coated with a proprietary rubberized asphalt adhesive.

Aero-Block SA is specifically engineered for vertical air, vapor and water barrier appli¬cations where the membrane is protected from long-term ultraviolet exposure. It adheres aggressively to most clean, dry substrates including metal, wood, vinyl and masonry. It can be used to seal an entire wall, around penetrations like windows and doors, as a through-wall flashing or to protect walls from the damaging effects of the elements.
