Data Sheet



Henry Blueskin SA Low Temp 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. Henry Blueskin SA Low Temp is designed for application at low temperatures. Questions? Contact Us.

Blueskin SA LT is designed for use as a self-adhered air, vapor and water resistive barrier. It can also be used as a transition sheet in conjunction with Henry Air-Bloc fluid applied air barriers where greater movement is anticipated due to its high strength. Blueskin SA LT is also used for tying into metal on curtain walls, windows and doorframes.

Surface Prep: All surfaces to receive Blueskin SA LT must be clean of oil, dust and excess mortar. Acceptable substrates are exterior-grade gypsum sheathing, plywood, OSB, precast or cast-in-place concrete, concrete block, primed steel, aluminum mill finish, anodized aluminum and galvanized metal. Strike masonry joints flush. Concrete surfaces must be smooth and without large voids, spalled areas or sharp protrusions. Concrete must be cured a minimum of 14 days and must be dry before Blueskin SA LT is applied. Where curing compounds are used, they must be clear resin based, without oil, wax or pigments.

Apply: Position Blueskin SA LT for alignment and remove release film and press firmly in place. Roll membrane, including seams, with a countertop roller to ensure full contact once in place. Membrane must be rolled after application to ensure adhesion to substrate and laps. Blueskin SA LT must be lapped a minimum of 2” (50 mm) on both sides and end laps. When using with brick ties, position, press in place and cut for ties or projections. Seal around any openings and at leading edge at the end of the workday with 925 BES Sealant, Air-Bloc 21 or Air-Bloc
21FR. Detail work must be carefully carried out to ensure continuous air tightness of the membrane. It is recommended that mechanical attachment be made to all window and doorframes, or a properly designed sealant joint be provided.
