3-1 SOPRASMART BOARD

3-1 SOPRASMART BOARD

3-1 SOPRASMART BOARD 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 3-1 SOPRASMART BOARD, a semi-rigid, asphaltic roofing substrate board is factory laminated to 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 or a fine mineral aggregate to optimize cold adhesive and hot asphalt applications.

Installation

Prior to installation, unfold 3-1 SOPRASMART BOARD onto the roof surface and allow to relax. 3-1 SOPRASMART BOARD is installed via mechanical fastening, approved adhesive or hot asphalt following manufacturer specifications. When installing via mechanical fastening, 3-1 SOPRASMART BOARD 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 3-1 SOPRASMART BOARD via heat welding. Refer to SOPREMA SBS Roofing Guide for additional application guidelines.

When searching for a roofing solution that met all codes and requirements, it was decided that a modified bitumen three ply roof system with a SOPRASTAR® cap ply would replace the existing roof. The SOPRASTAR® cap ply membrane easily met both the Miami- Dade code and Factory Mutual (FM) guidelines, making it one less concern.
