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.
As part of its commitment to serving its customers, Duro-Last Inc. is pleased to make Duro-Tuff and Duro-Fleece colors available in 80 mil. Colors available include blue, charcoal, copper, dark green, light gray, light tan, patina and white.
When correctly engineered into a roof assembly, it will contribute to long-lasting thermal and waterproofing performance in all climate zones for all colors including white membranes provided by Duro-Last.
