ELASTOPHENE HR Sanded 2.2 (high resistance) is an SBS-modified bitumen base ply for use in approved multi-ply membrane and flashing assemblies. ELASTOPHENE HR Sanded 2.2 is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with high performance glass scrim. The topside and underside are surfaced with fine mineral aggregate to facilitate cold adhesive application.

Installation

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