energy star^® support

The ENERGY STAR® program is a major business driver for residential fenestration manufacturers, and at Quanex, we’re committed to being your ENERGY STAR partner with advanced technologies and design and engineering assistance to help you meet even the most stringent new criteria.

To achieve ENERGY STAR® status, windows must be National Fenestration Rating Council (NFRC) approved and labeled for U-Factor (the rate of heat loss through the window) and Solar Heat Gain (how well the window blocks heat from the sun). In warmer climates, solar heat gain can warm air-conditioned indoor space causing excessive energy consumption.

We stay up to date on ever-evolving ENERGY STAR criteria to help you understand zone-specific requirements. Then we help you select the right components, designed in the right configurations, to meet ENERGY STAR program requirements in the way that works best for your business and your operations. We’ll help you model new designs to find the right fit.

Between our advanced, energy-efficient Mikron suite of vinyl window profiles and our proven warm-edge spacer technology, a solution that’s right for you is at hand. Deliver the ENERGY STAR windows your customers demand with Quanex.
