The 2016 Dealer Design Award gold-winning ventilation product, the Horizontal Mount Damper in Non-Concrete 2 Hour Fire Rated Barrier from Greenheck Fan Corp., was designed to protect duct penetrations and air-transfer openings going through horizontal non-concrete barriers. The line of fire and combination fire/smoke dampers can 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 series dampers in a horizontal non-concrete barrier results in more usable space for the owner, more flexibility for the design professional, and reduced installation time for contractors.
“I like that it’s versatile. We can put it in a raised structure that is not concrete,” said Eddie McCubbins, vice president of J&F Mechanical in Rutledge, Tennessee, who used the product during a project on a resort in Gatlinburg, Tennessee. “Often times, ceiling space is at a premium. So, framing down into the ceiling space really hurts. The fact we can damper right at the floor or roof levels is a huge deal. And Greenheck has excellent customer service and support.”
