Abstract:
This invention provides a duct cover system for ducts installed in exposed locations. For use primarily with ducts having generally rectangular cross sections, the duct cover system provides a roof over the duct that may be integral with the duct or retrofitted to the duct. The roof includes at least one cover panel extending along the duct length. The cover panel is inclined laterally relative to the duct bottom wall thereby to shed water and prevent snow accumulation.
