New Greenheck Dampers Protect Non-Concrete Fire Rated Barriers

Greenheck introduces the industry’s first line of fire and combination fire/smoke dampers approved for installation in horizontal, non-concrete, fire rated barriers.  Greenheck’s DFD, FD and FSD Series dampers can now be specified for use in UL floor/ceiling design I503, which is a two-hour fire rated floor/ceiling assembly made from steel studs and gypsum board.  This unique installation method greatly simplifies the difficult task designers and contractors face trying to protect 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 reduces installation time for contractors.


Greenheck, the worldwide leader in manufacturing and distributing air movement, conditioning and control equipment, offers the most UL certified dampers and the largest selection of AMCA licensed dampers in the industry.
