Commonly used to prevent drafts and provide a weathertight seal around windows and doors, joints in sheathing, sealing around skylights, and as a flashing in residential construction. Uses include: Concealed self-adhered air and vapor barrier membrane and protection against rain and moisture penetration. Membrane is self-sealing when penetrated with self-tapping screws or nails. OSI QUAD was the ONLY sealant that sticks blueksin (polyethylene), azek (PVC), window frame (PVC), tyvek (spun polyolefin), etc. Where the window frame meets the blueskin, that white caulking is OSI QUAD as well. It sticks the white aluminum capping to the azek. Easy-to-install peel and stick application, no flame required. Henry Blueskin VP100 is a next generation vapor permeable air barrier that picks up where traditional polymeric wraps leave off. The clear sealant on top of the white azek frame is clear OSI QUAD. Impermeable to air, moisture vapor, and water. Excellent adhesion to prepared substrates of concrete, concrete block, primed steel, aluminum mill finish, anodized aluminum, galvanized metal, gypsum board, and plywood. Features include: Application in temperatures as low as -12 deg. The membrane is specifically designed to be self-adhered to a prepared substrate. Blueskin WB25 window and door flashing is a self-adhered membrane consisting of an SBS (styrene-butylene-styrene) rubberized asphalt compound which is integrally laminated to a blue engineered film.
