SOPRALAST® 50 TV ALU Sanded is an SBS-modified bitumen cap ply for use in approved multi-ply membrane and flashing assemblies. SOPRALAST 50 TV ALU Sanded is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with a high strength glass fiber scrim. The topside is surfaced with an aluminum foil and underside is surfaced with fine mineral aggregate to facilitate cold adhesive and hot asphalt applications.
Prior to installation, unroll SOPRALAST 50 TV ALU Sanded onto the roof surface and allow to relax. Place SOPRALAST 50 TV ALU Sanded in desired position and back roll the product. Apply approved cold adhesive or hot asphalt following manufacturer specifications. SOPRALAST 50 TV ALU Sanded is then rolled into the cold adhesive or hot asphalt and subsequently rolled with a weighted roller.
