SOPRALENE 180 FR+ GR (fire retardant, granulated) is an SBS-modified bitumen cap ply for use in approved multi-ply membrane and flashing assemblies. SOPRALENE 180 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 non-woven polyester mat. 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 SOPRALENE 180 FR+ GR onto the roof surface and allow to relax. Place SOPRALENE 180 FR+ GR in desired position and back roll the product. Apply approved cold adhesive following manufacturer specifications. SOPRALENE 180 FR+ GR is then rolled into the cold adhesive and subsequently rolled with a weighted roll if utilizing cold adhesives. Refer to the SOPREMA SBS Roofing Guide for additional application guidelines.
