Courtesy: GreenheckGreenheck's DFD, FD, and FSD series fire and combination fire/smoke dampers are approved for installation in horizontal, nonconcrete, fire-rated barriers. They can be specified for use in UL floor/ceiling design I503, which is a 2-hour fire-rated floor/ceiling assembly made from steel studs and gypsum board. This installation method simplifies the process of protecting duct penetrations at the top and bottom of fire-rated building shafts. Installing DFD, FD, and FSD series dampers in a horizontal non-oncrete barrier results in increased usable space for the owner, flexibility for the design professional, and reduced installation time for contractors.
