The Blueskin SA is a self-adhered water resistive air barrier consisting of an SBS rubberized asphalt compound, which is integrally laminated to a blue engineered thermoplastic film surface. It is specifically designed to be self-adhered to a prepared substrate providing an air, vapor and water resistive barrier in full wall applications or as penetration/flashing membrane with other air barrier systems. Blueskin SA is a self-adhering membrane consisting of an SBS rubberized asphalt compound laminated on a blue polyethylene film. Impermeable to air, moisture vapor and water, Blueskin SA is designed to install easily on a variety of prepared substrates.
