ELASTOPHENE LS FR GR (low slope, fire retardant, granulated) is an SBS-modified bitumen cap ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE LS FR GR is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a high quality random glass fiber 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 ELASTOPHENE LS FR GR onto the roof surface and allow to relax. Place ELASTOPHENE LS FR GR in desired position and back roll the product. Apply approved cold adhesive following manufacturer specifications. ELASTOPHENE LS FR GR is then rolled into the cold adhesive and subsequently rolled with a weighted roller. Refer to the SOPREMA SBS Roofing Guide for additional application guidelines.
