ELASTOPHENE® Flam 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 Flam 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 underside is surfaced with polyolefin burn-off film to optimize heat welding.
Prior to installation, unroll ELASTOPHENE Flam LS FR GR onto the roof surface and allow to relax. Position ELASTOPHENE Flam LS FR GR in desired position and back roll the product. ELASTOPHENE Flam LS FR GR is then heat welded to approved substrates. Refer to the SOPREMA® SBS Roofing Manual for additional application guidelines.
