G. Membrane Flashing Bonding Adhesive: A solvent-based reactivating-type adhesive used to attach the flashing membrane to the substrate, either horizontally or vertically. Application rates are to be as recommended by thermoplastic sheet manufacturer's printed instructions. The solvent-based reactivating-type adhesive is to install in such a manner to develop a bond between the membrane and the substrate to which the membrane is to be attached.

H. Metal Termination Bars: Manufacturer’s standard aluminum bars, approximately 1-inch (25-mm) wide, roll formed and pre-punched every 6 inches on center.
