Fire Resist 705FR-A XLT Air & Vapor Barrier is a 40-mil-thick (0.040 inch) self-adhered sheet air and vapor barrier composite membrane consisting of a rubberized-asphalt adhesive laminated to fire resistant aluminum foil/HDPE composite facer. Fire Resist 705FR-A XLT is manufactured with a highly-tacky adhesive formulated for installation between 15°F and 60°F, ambient and substrate temperature. In addition to being tough and dimensionally stable, the facer provides heat reflectivity and fire resistance.

Fire Resist 705FR-A XLT is provided in rolls of various widths lined with disposable silicone-coated release paper. The release paper is removed to expose the adhesive as the membrane is pressed in place. Fire Resist 705FR-A XLT provides a complete barrier to moisture and air when adhered to an above-grade substrate. Cut sizes are also useful for other above-grade wall flashing applications. Fire Resist 705FR-A XLT is cold applied and will adhere firmly when pressed against the substrate.
