Ce r t a i nTe e d P o l yis o c ya nura t e R oof Insul ati on Pr oducts Faste ni ng G uid e FlintBoard Polyisocyanurate Roof Insulation Products In conjunction with General Recommendations Section 15.4.1 of the CertainTeed Roof Systems Manual, CertainTeed recommends the designer consult with local code agencies as well as applicable insurance rating bureaus, such as FM Global, prior to wind uplift calculations to determine fastener placement and densities in the field and at perimeters and corners. The diagrams in this guide are suggested as default patterns. For fastening densities not featured in this guide the designer should consider: • Edge fasteners are a minimum of 6" from insulation board edges • Fasteners are evenly distributed over the board area • All fasteners engage the top flange of steel decking Fastener Placement 4 x 4 ft.
