Owens Corning™ FlashSealR® Foam Flashing Tape is a durable, flexible and tearresistant self-adhering flashing tape recommended for use with FOAMULAR® Extruded Polystyrene (XPS) Sheathing products in residential and commercial construction applications to seal around window and door openings. The aggressive, pressure-sensitive acrylic adhesive provides excellent adhesion to FOAMULAR® 150 or 250 Insulation, FOAMULAR® Insulated Sheathing, or FOAMULAR® PROPINK® Sheathing and other common building substrates including OSB, plywood, vinyl and spunbonded polyolefin housewrap. FlashSealR® Foam Flashing Tape helps provide effective protection against air infiltration and water penetration and can be applied over a wide range of temperatures.
FlashSealR® Foam Flashing Tape is self-adhering and cold applied. No special adhesives or primers are needed for most applications. For best adhesion, the tape should be applied over the foam sheathing at the time the sheathing is installed. Resistance to air intrusion enhances the thermal and moisture resistance of buildings by minimizing intrusion of unconditioned, moisture laden air into the wall assembly. Acting as a water resistive barrier, it provides a secondary layer of external moisture resistance behind the cladding to protect the building.
