Benefits of Solar Powered Attic Fans

With solar powered attic fans, Fafco Solar can help you achieve:

• Lower attic temperature which in turn reduces the load on your HVAC System. Attic temperatures can exceed 160 F during hot summer days. Proper attic ventilation can reduce those temperatures by 50 F. Attic insulation can actually add to temperature increases because heat is trapped in the insulation. Proper ventilation evacuates this excess heat build-up. As the heat is exhausted the work of the air conditioning system is reduced thereby saving energy and extending the life of the air conditioning system.

• A longer life for your roof. Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is what happens in an under ventilated attic in the warmer months. In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers, there are air leaks around ceiling light fixtures, and bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing.
