Electric-powered attic vents use a thermostat to fight heat and a humidistat control to help prevent moisture buildup inside the attic. Electric Attic Fan Featuring a low-profile dome, the power attic vent is unobtrusive when installed on the roof face slanting away from the front of your home. It's an efficient option to replace wind turbines or roof pots already in place. Roof-mount power attic ventilators are available in several CFM capacities and dome colors that blend with the color of your roof shingles.
A typical family of four produces an average of 2 to 4 gallons of water vapor per day in a home. In the winter this vapor is attracted to the cooler air in the attic, where it quickly condenses. Condensation can drip onto attic insulation, reducing its effectiveness. This moisture can cause wood rot to the attic structure and promote the growth of mold and mildew, affecting the quality of the air in the home. So, for added protection, install a power vent equipped with a humidistat.
1.Pre-painted 22-gauge galvanized steel dome is more durable than aluminum. Screws are painted to match dome color. 2.Raised dome for greater airflow and easier flashing. 3.Plastic screen has distinct advantages over metal: it won't corrode or rust and it won't vibrate or create noise. 4.Six brace struts hold dome firmly in place. 5.Oversized 24" × 24" G-90 galvanized base flange for easy nailing and flashing. 6.Stiffening rib improves edge sealing and adds rigidity.
