Torchflex TF-95-SF-Base (3.0 mm) Heat Welded Base Sheet is constructed of an inorganic reinforcing mat of high strength non-woven glass fibers, which is coated with SBS polymers and premium quality asphalt both top and bottom. The surface of the product is sanded to prevent sticking in the roll during application and to allow cap sheets to be installed via mopping asphalt or an IKO-approved cold process adhesive. The underside is covered with a thin micro-perforated film surface that conveniently disappears upon heat welding to the substrate. Torchflex TF-95-SF-Base (3.0 mm) can be used as the “lay-flat” base sheet in a layered membrane construction system, and also as a vapour retarder.
