Greenheck's Non-Concrete Damper Installation Featured in New Video
design deals with protecting duct penetrations at the top and bottom of fire-rated building shafts, and highlights
how Greenheck DFD, FD and FSD Series dampers are the only fire and fire/smoke dampers approved for use in UL floor/ceiling design I503. Installing these Greenheck 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.
