Why choose ENERGY STAR® qualified windows and doors from JELD-WEN?

Replacing old windows with ENERGY STAR qualified windows can lower household energy bills by 7 to 15 percent, according to the U.S. Environmental Protection Agency (EPA). Lower energy consumption also reduces greenhouse gas emissions from power plants and shrinks a house’s carbon footprint.

With thousands of ENERGY STAR qualified windows and doors, JELD-WEN can help improve the comfort and energy efficiency of your home while also providing style and long-lasting durability. Simply tell your JELD-WEN dealer that you want ENERGY STAR qualified windows and doors.

How do JELD-WEN® windows and doors earn the ENERGY STAR® label?

To earn the ENERGY STAR label, windows and doors must meet rigorous energy performance levels. Qualified products must also have third-party certification based on testing in recognized laboratories.

ENERGY STAR divides the U.S. into four climate zones, each with its own unique set of energy performance requirements (shown at right). Energy efficiency for windows and doors is compared by using two important measurements: U-FactorU-Factor: U-factor measures insulating value and indicates how much heat or cold transfers through the window or door. The lower the U-factor, the more energy efficient the product is. and Solar Heat Gain Coefficient (SHGC)SGHC: Solar heat gain coefficient (SHGC) measures a window’s ability to block the sun’s heat. The more solar heat it blocks, the lower the SHGC number. Where air conditioning is prevalent, ENERGY STAR requires a lower SHGC. Where heating is more prevalent, opt for a higher SHGC so the sun’s rays can stream in on cold winter days..

In the northern zones, U-Factor and SHGC requirements focus on helping reduce the need for heating. In the southern zones, requirements generally aim to reduce the need for air conditioning. Special glass coatings help control how much of the sun's heat enters and how much of the controlled air temperature inside escapes.

Because JELD-WEN offers a variety of glazing packages, including several high performance glass options, a professional JELD-WEN dealer can configure windows best suited for your climate zone.
