A Lock-Top damper or energy-saving damper is a damper that is connected to the chimney system at the top of the flue. Like a throat damper, it has an easy-to-use cable for opening and closing the flue (donât worry â you wonât have to go up on the roof!), but unlike a throat damper, a Lock-Top damper provides an airtight seal.
Fire Dampers and Ceiling Radiation Dampers shut-down air circulation thru system Grilles and Registers as part of Fire and Smoke Control. Iris Dampers are installed in round duct for precise airflow and balancing. Barometric Dampers and Draft Inducers control and improve furnace venting and chimney draft.
