Greenheck’s DFD, FD, and FSD series fire and combination fire/smoke dampers are approved for installation in horizontal, non-concrete, fire-rated barriers. These dampers 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 unique installation method greatly simplifies the difficult task of protecting duct penetrations at the top and bottom of fire-rated building shafts. Installing Greenheck’s DFD, FD, and FSD series dampers in a horizontal non-concrete barrier results in more usable space for the owner, more flexibility for the design professional, and greatly reduced installation time for contractors.
