CP685 is a torch-applied, bituminous cap sheet which is saturated and coated with high quality SBS (Styrene-Butadiene-Styrene) modified bitumen. It has a 180 g/m² polyester fleece reinforcement, a thermo-fusible polyethylene film on the underside and has a slate surfaced finish. CP685 also incorporates a special graphite additive within the coating to provide exceptional fire protection properties.
CP685 is designed for use as a high performance cap sheet, and can be used as the final waterproofing layer on a variety of TREMCO built-up roofing systems (e.g. Torch-Safe and full Torch-On specifications). CP685 is compatible with all common bituminous underlay membranes.
