CP684 is a torch-applied, bituminous underlay 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 is finished on the top surface with a fine slate.
CP684 is designed for use as a premium underlay membrane, and is ideal for use as part of a high performance torch-on roofing system. It can be applied to a wide range of non-combustible substrates and can also be used as the final waterproofing layer on certain built-up roofing systems. (Please consult CPG Europe Technical Services for details).
