2-1 SOPRASMART® ROCKSKU:

2-1 SOPRASMART ROCK is a high performance panel composed of an SBS-modified bitumen base membrane and HD SOPRAROCK high density mineral wool board for use in approved multi-ply membrane assemblies. To create 2-1 SOPRASMART ROCK, high density mineral fiber board is factory laminated to an SBS modified bitumen base ply reinforced with a tough, dimensionally stable, non-woven polyester mat creating a time and labor-saving solution. The topside is surfaced with polyolefin burn-off film to optimize heat welding applications or a fine mineral aggregate to optimize cold adhesive and hot asphalt applications.
