ELASTOPHENE HS FR GR (high strength, fire retardant, granulated) is an SBS-modified bitumen cap ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE HS FR GR is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a tough, dimensionally stable composite polyester/glass fiber reinforcement. The topside is surfaced with ceramic coated granules and the underside is surfaced with fine mineral aggregate to facilitate cold adhesive application.

Installation

Prior to installation, unroll ELASTOPHENE HS FR GR onto the roof surface and allow to relax. Place ELASTOPHENE HS FR GR in desired position and back roll the product. Apply approved cold adhesive following manufacturer specifications. ELASTOPHENE HS FR GR is then rolled into the cold adhesive subsequently rolled with a weighted roller.
