SOPRALENE Flam Stick is an SBS-modified bitumen, self-adhered base ply for use in approved multi-ply membrane and flashing assemblies. SOPRALENE Flam Stick is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen in combination with a high tack self-adhesive layer and is reinforced with a tough, dimensionally stable non-woven polyester mat. The topside is surfaced with polyolefin burn-off film to optimize heat welding and the underside is surfaced with protective polyolefin release film that is removed during application.
Prior to installation, unroll SOPRALENE Flam Stick onto the roof surface and allow to relax. Place SOPRALENE Flam Stick in desired position. Remove the protective release film from the underside of the sheet and roll SOPRALENE Flam Stick into place with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to SOPRALENE Flam Stick via heat welding. Refer to the SOPREMA® SBS Roofing Manual for additional application guidelines.
