ELASTOPHENE® Sanded 2.2 is an SBS-modified bitumen base ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE Sanded 2.2 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 fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.

Installation

Prior to installation, unroll ELASTOPHENE Sanded 2.2 onto the roof surface and allow to relax. Place ELASTOPHENE Sanded 2.2 in desired position and back roll the product. Apply approved cold adhesive or hot asphalt following manufacturer’s guidelines. ELASTOPHENE Sanded 2.2 is then rolled into the cold adhesive or hot asphalt and subsequently rolled with a weighted roller. Subsequent approved inter-ply or cap ply membranes are applied to ELASTOPHENE Sanded 2.2 via cold adhesive or hot asphalt. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
