Cat 5

air and waterproof barrier

Cat 5 is a primary air barrier designed for use over above-grade structural surfaces prepared with Joint & Seam Filler and FastFlash. Cat 5 produces a highly durable, seamless, elastomeric weatherproofing membrane on exterior sheathing, CMU backup walls, and precast concrete. Proven to prevent water and air penetration of the building envelope in conditions ranging from everyday to the 155-mph winds of a Category 5 hurricane.
