SOPRALENE® ULTRA-STICK® FR GR (fire retardant, granulated) is an SBS-modified bitumen cap ply for use in approved multi-ply membrane and flashing assemblies. SOPRALENE® ULTRA-STICK® FR GR is composed of a proprietary formulation of elastomeric styrene butadiene-styrene (SBS) polymer modified bitumen in combination with a specifically formulated, high tack self-adhesive bottom layer 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 a protective embossed split back release film that is removed during application.

Installation

Prior to installation, unroll SOPRALENE ULTRA-STICK FR GR onto the roof surface and allow to relax. Place SOPRALENE ULTRA-STICK FR GR in desired position. Remove one side of the embossed split back release film and use hand pressure to adhere the exposed high tack bottom layer. Remove the other half of the release film and use a weighted roller to adhere the entire surface of the sheet. Refer to the SOPREMA SBS Roofing guide and additional application guidelines.
