A hot attic acts like a giant radiator, transferring heat into your living spaces, sending both utility bills and temperatures soaring.Installation of solar ventilation and exhaust fan system on roof can eliminate a lot of heat in indoor air in hot summer, reduce up to 50% of the use of air conditioning equipment for indoor cooling, and make your indoor life more comfortable.
