Improve the comfort, efficiency, and longevity of your home by removing hot air and moisture from your attic with the award-winning solar attic fan from U.S. Sunlight. By removing excess heat in your attic, you can be more comfortable in your home, reduce energy usage, and save money. Attic temperatures can reach 160°F or more in the summer. These elevated temperatures can have devastating effects on your roof, temperatures on the top floors, and the overall health of your home. Moisture and condensation can form in the attic during the colder months causing the negative effects of mold and mildew growth, wood rot, musty odors, wet attic insulation, and ice damming. Reducing attic moisture can protect your shingles, roof deck, rafters, and insulation from costly long-term damage. The solar attic fan is designed for do-it-yourself installation, and can typically be completed in a single afternoon. If you'd like to hire professional, U.S. Sunlight has a nationwide network of certified installers who can help. For details, or to find an installer near you, call: 877-50-USSUN.
