SOPRALENE Stick is an SBS-modified bitumen, self-adhered base ply for use in approved multi-ply membrane and flashing assemblies. SOPRALENE 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 tough, dimensionally stable non-woven polyester mat. The topside is surfaced with fine mineral aggregate to facilitate self-adhered or cold adhesive applications and the underside is surfaced with protective polyolefin release film that is removed during application.

Installation

Prior to installation, unroll SOPRALENE Stick onto the roof surface and allow to relax. Place SOPRALENE Stick in desired position. Remove the protective release film from the underside of the sheet and roll SOPRALENE Stick into place with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to SOPRALENE Stick via self-adhered or cold adhesive applications. Refer to the SOPREMA SBS Roofing Guide for additional application guidelines.
