Owens Corning Proper Vents:
Proper vents assist in the constant flow of fresh air from soffit vent to attic. and cooling costs.
Recommended for finished attic spaces.
How Ventilation Works:
In a balanced system, wind blowing over the ridge and roof vents creates negative pressure that draws the warmer air out of the attic. Replacement air then enters through the undereave or soffit vents, bathes the underside of the roof, and exits at the ridge cap through ridge, roof or gable vents. Even without wind, the natural convection action of rising warm air maintains a continuous air flow along the underside of the roof. Ultimately, proper ventilation – along with attic insulation – helps maintain a comfortable temperature inside a home, increase energy efficiency, prevent moisture damage and contributes to the longevity of a roof.
One of the most straightforward ways to help meet energy codes as a builder or architect, while still designing bright, airy buildings, is to specify ENERGY STAR® certified products. Most VELUX residential products are ENERGY STAR® certified in all 50 states, which means they meet energy efficiency standards set by the US Environmental Protection Agency (EPA). In order to be ENERGY STAR® certified, fenestration products must have their U-factor, Visible Transmittance, and Solar Heat Gain Coefficient ratings independently tested and approved under the FenStarSM Certification Program of the National Fenestration Rating Council (NFRC) to qualify.
By using ENERGY STAR® certified products, architects and builders can use skylights to bring much needed daylight and fresh air inside, allowing them to create more attractive buildings and more livable spaces while still meeting local energy codes. In warmer climates, there is great potential for lighting energy savings by using emerging control technologies like VELUX ACTIVE or more effective daylighting products like VELUX skylights with blinds and Sun Tunnel® Skylights
