Firestone's V-Force Vapor Barrier Membrane can be used as a self-adhered temporary roof
Firestone Building Products' V-Force Vapor Barrier Membrane can be used as a vapor barrier and self-adhered temporary roof. V-Force membrane may be used over a variety of substrates, including concrete, plywood, DensDeck Prime roof board, exterior gypsum and other Firestone-approved substrates primed with V-Force solvent-based or water-based primer. V-Force membrane’s high tensile woven polyethylene surface is designed for the adhesion of Firestone insulation products above the barrier and adhesion to substrates below.
With its puncture and UV resistance, V-Force membrane also functions as a temporary roof. V-Force is UL and FM approved when used with approved assemblies and is recognized by the International Building Code as a Class l vapor retarder with a perm rating of 0.02.
