SOPRASMART Board 180 Sanded is a high performance panel of an SBS-modified bitumen base membrane and SOPRABOARD asphaltic coverboard for use in approved multi-ply membrane assemblies. To create SOPRASMART Board 180 Sanded, a semi rigid, asphaltic roofing substrate 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 surface with a fine mineral aggregate to optimize cold adhesive and hot asphalt applications.
Prior to installation, unfold SOPRASMART Board 180 Sanded onto the roof surface and allow to relax. SOPRASMART Board 180 Sanded is installed via mechanical fastening, approved adhesive or hot asphalt following manufacturer specifications. When installing via mechanical fastening, SOPRASMART Board 180 Sanded is fastened through the patented DUO SELVEDGE lap following the details for the uplift pressure required. Subsequent approved inter-ply or cap ply membranes are applied to SOPRASMART Board 180 Sanded via cold adhesive and hot asphalt applications. Refer to SOPREMA SBS Roofing Manual for additional application guidelines.
