ENERGY STAR Requirements

  Look for the ENERGY STAR label. Pella Corporation is a proud volunteer partner in the Department of Energy’s ENERGY STAR program to promote the use of high-efficiency products.

Most Pella® products with Low-E insulating glass meet or exceed ENERGY STAR guidelines in all 50 states.* In fact, we have some products that have U-Factors that significantly exceed U.S. ENERGY STAR guidelines.

U-Factor. The lower the U-Factor, the better the window insulates.

Solar Heat Gain Coefficient. This number tells how effective the product is at blocking the sun’s radiant heat. The lower the solar heat gain coefficient, the less solar heat the window allows into your home.
