SOPRASMART® Board 180 ISO is a high performance panel of an SBS-modified bitumen base membrane, SOPRABOARD asphaltic coverboard and two inches of SOPRA-ISO polyisocyanurate insulation for use in approved multi-ply membrane assemblies. To create SOPRASMART Board 180 ISO, a semi rigid, asphaltic roofing substrate board is factory laminated to two inches of SOPRA-ISO and then 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 surface with polyolefin burnoff film to optimize heat welding applications.
