Weatherproof, sand-finished underlay (part of a 2-layer system). Polyester reinforced for better tear resistance. Less heat required to melt SBS bitumen than APP and more flexible in a wider temperature range. Torch-on underlay membranes are rolled and applied hot, using a propane torch to heat the underside, which releases the molten bitumen to provide adhesion to a flat roof.
