Attic Venting Key Concepts
Attic ventilation is an important aspect of maintaining the structure of your home as well as saving energy. Improper attic venting can lead to moisture buildup that can cause mold growth and also cause wood rot. The key to proper attic ventilation is to create continuous air circulation throughout the attic space while preventing moisture from entering. In an ideal venting system, air should enter the attic from the eaves or soffits and escape outside at the roofs ridge.
Solar Attic Fans Work With Your Existing Passive Vents
If you’ve ever been in your attic, you know just hot the space can get, especially in summer months. The sun beats down on the roof surface and heats up the stagnant air inside the attic. Building codes require homes to have a passive vent system. But, passive ventilation does not provide the pressure needed to force the air through the attic and outside. That’s where a motorized fan comes in. An attic fan placed at the roofs ridge will pull air in from outside, force it to move through the entire attic space and escape through the attic vent.
In summer months, a solar attic fan can reduce the temperature in an attic by up to 40°F!
