Abstract:
An environmental exhaust duct adapted to be mounted on a roof allows for exhaust gases to escape while preventing water and debris from entering the building. The exhaust duct has a flap which is closed over the duct by gravity, and which pivots upwards when exhaust gases are released. A cap over the duct prevents water and debris from entering the air shaft when the flap is open.
