Torchflex TF-95-FF Base (2.2)
Consists of a reinforcing mat of non-woven glass fibres coated and permeated with SBS bitumen to a thickness of approximately 2.2 mm (87 mils). A thin poly-film covers both surfaces. Upon application, the top-film will melt with the heat-welded cap sheet while the bottom film dissolves during heat-welding to the substrate. Product can be used as a base sheet with a Torchflex or Armourplast Cap Sheet.
Consisting of a non-woven reinforced polyester reinforcing mat that is coated and impregnated with SBS modified bitumen to a nominal thickness of 4.0 mm (158 mils). Ceramic mineral granules are embedded in the surface to provide U.V. protection and a poly-film is bonded to the underside (which disappears upon heat-welding). TP-250-Cap can be used as a cap sheet in a conventional BUR system, a two-ply Torchflex system, or in roof flashing.
