ELASTOPHENE® Flam is an SBS-modified bitumen base ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE Flam 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 and underside are surfaced with polyolefin burn-off film to optimize heat welding.
Prior to installation, unroll ELASTOPHENE Flam onto the roof surface and allow to relax. Position ELASTOPHENE Flam in desired position and back roll the product. ELASTOPHENE Flam is then heat welded to approved substrates. Subsequent approved inter-ply or cap ply membranes are applied to ELASTOPHENE Flam via heat welding. Refer to the SOPREMA® SBS Roofing Manual for additional application guidelines.
