Johns Manville has debuted the DynaFast product series, developed from its first-generation ASTM D6164 DynaLastic platforms. DynaFast SBS modified bitumen membranes are designed to be mechanically fastened. Together, DynaFast 180 S, DynaFast 180 HW and the DynaFast250 HW provide a vast assortment of options to customize any commercial roofing job. The system requires fewer fasteners for the same wind-uplift rating as traditional system fastening and gives you the choice of fasteners. DynaFast may be used in high and low wind zones. There’s an application for every job, including hot, cold and heat-weld applications. Roll lengths of 1 square or 1 1/2 square with varied thicknesses mean faster installation.
