Roof termination dryer vent.

Clothes dryer exhaust vent termination at walls or rooftops. Clothes dryer vents should terminate outdoors and should be screened enough to prevent entry by animals as well as to minimize cold back drafting when the dryer is not in operation. Since many laundry rooms are located in the middle of the house and so many homes are single story with easy to walk on roof slopes about 6 12 venting the dryer to the roof makes the most sense shortest run with least amount of elbows. Venting dryers to a roof termination or roof cap is very common in the south.

The position and curvature of the damper combined with collar placement optimize airflow efficiency. If the manufacturer s instructions do not specify a termination location the exhaust duct shall terminate not less than 3 feet 914 mm in any direction from openings into buildings. Until now however there were no roof terminations that met all of the stringent dryer venting requirements. Unlike the vents shown above left the dryerjack affects airflow by less than 01 water column inches of pressure.

The new dryerjack is engineered specifically for dryers. Efficient dryer roof termination dryerjacks are the first roof vents designed to meet the more stringent requirements for dryer venting.
