Attic Ventilation
Why you should consider and attic fan this winter.
Most homeowners buy attic fans in the summer. That’s when they’re most concerned about venting hot air before it can build up and overheat their homes. But here’s a fact many people don’t know: attic fans are just as important, if not more so, in the winter. That’s when moisture accumulation tends to increase due to extreme temperature variances, and it can be just as damaging to a home as heat. This silent menace can prompt leaks, mold and fungus growth, insulation damage, and wood rot.
During summer, hot air that builds up in an attic flows downward into the living spaces below. In the winter, the process reverses. As heated, interior air moves throughout a home, it collects water vapor that is created when homeowners bathe, cook, wash dishes, do laundry, and run humidifiers. The warm, moist air then travels into the attic where the air is cooler and drier. Even homes with vapor barriers are vulnerable because air can travel through openings around light fixtures, bathroom exhaust fans, and attic entrances into the upper recesses of a home.
All homes are at risk for moisture accumulation, even newer ones that use advanced insulation materials and methods to make them more energy efficient. The drawback is that this also keeps cooler, drier exterior air out, so interior air tends to hold more moisture.
An attic fan helps by equalizing the indoor and outdoor temperatures. By continually exchanging warm, moist air from inside the attic with cooler, drier air from the outside of the home, it prevents condensation from occurring. The ventilation process also helps to maintain even attic temperatures.
Installing an attic fan before winter cold temperatures hit can help eliminate structural damage and costly home repairs. Solar Star Attic Fans by Solatube offer a simple, affordable and easy solution for common attic ventilation winter woes.
