Attic Fan

Many people believe that a roof is a sealed unit. IT IS NOT! Roofs must breathe so that water vapor is not trapped causing condensation that ultimately rots wood and rusts fasteners. This is not the only reason. Ventilation permits air to enter through the soffit eave vents and flow out through the eyebrow vents placed in the roof top. Modern day scientific proof indicates that ventilation is more important than ever before in reducing energy costs and preventing mold and mildew. You may have noticed the metal vents on top of the roof. This is where hot air is exhausted during the summer, and moisture laden air is exhausted in the winter. This point alone fosters energy conservation so much that your utility company is offering generous rebates for improving it.* Ventilation's two part system consists of

In certain applications it is even more beneficial to include an attic fan to assist in the natural flow of air through the attic/roof. During the summer months temperatures in the attic can rise to 160 degrees or more building up heat in the attic that cause cooling equipment to work harder and use more energy. During the winter moisture migrates to the attic from shower stalls, washing machines and dishwashers. This damp laden air needs to be expelled to prevent water damages. Quiet fans are available in low power regular power and solar power with automatic thermostatic switches or conventional switches that make the fan start and stop depending on the needs. Does your roof need improved ventilation?

During the peak summer months, your attic's temperature can rise to 160° or more. This heat build up can raise the temperature inside your home and increase the amount of electricity used by air conditioners and other cooling equipment.

During the winter months, warm moist air from inside your home rises into the attic and collides with the colder underside of the roof. The moist air condenses and promotes mold and mildew. If you live in an area that has snow, the warmer attic air will heat the roof and melt the snow which drips to the eaves where it can refreeze as ice and form ice-dams under the eaves. These ice-dams will cause water to work back up under the shingles into the attic and down to the ceiling.

Lowers your energy costs - Attic temperatures can exceed 160° F in the summer months heating up air-condition ductiing and radiating heat into your home. This forces your air conditioning to work harder.

Removes Damaging Moisture - In the winter moisture is constantly added to your home by the washing machine, showers, and dishwasher. During the winter, this moisture can migrate to the attic and condense in the cool air promoting the growth of mold and mildew.

Adjustable Solar Panel and Shroud - It is important to capture as much of the available sunlight as possible. Orient the solar panel by tilting the panel and/ or rotating the shroud to the position that will face the sun at it's highest point during the day.

Oversized Flashing - US Sunlight's oversized flashing is made of a heavy gauge steel and has been designed for leak-proof installation. The attractive bronze powder coating blends in with any roof color.

Cools Your House In The Summer - By expelling the hot attic air and pulling in cooler air from the soffit vents, your house will stay cooler.

Ventilates up to 1250 square feet - One attic fan will ventilate up to 1250 square feet of attic space depending on the slope of the roof and available sunlight. Add more fans for larger attics.
