Fire Resist 705 VP Air Barrier, manufactured by Carlisle Coatings and Waterproofing, is a composite membrane consisting of a breathable specially engineered film fully coated on one side with a permeable adhesive. The adhesive side of Fire Resist 705 VP has a silicone-coated release film, which is removed and discarded during installation. Fire Resist 705 VP is provided in rolls of various widths and will adhere firmly when pressed against the substrate. Fire Resist 705 VP membrane permits passage of water vapor, yet it performs as a barrier to air and liquid water. Fire Resist 705 VP is designed for use in above-grade wall assemblies to function as an air- and water-resistive barrier. Fire Resist 705 VP can be applied over many common building materials including gypsum sheathing, foam sheathing, concrete masonry unit (CMU), concrete, wood, structural steel, metal flashings, aluminum extrusions and rigid PVC (i.e. pipe/conduit, window frames). Surface preparation with CCW-702 WB, CAV-GRIP™ or TRAVEL-TACK™ contact adhesive is often required to promote consistent adhesion.
