We publish standard energy-efficiency performance ratings on all our products ratings that are consistently among the best in the industry. Homes with Renewal by Andersen© products can dramatically help reduce their heating and cooling costs.
*Values are based on comparison to U-Factors and SHGCs for clear glass non-metal frame default values from the 2006 International Energy Conservation Code (IECC).
Poor performing windows are an energy drain and can account for a significant percentage of a
home’s heat loss in winter and heat gain in the summer.*
Renewal by Andersen® window replacement can save you money on your energy bills.
Plus, the great combination of our exclusive Fibrex® material, High-Performance™ Low-E4® glass, and expert installation means your Renewal by Andersen windows have excellent NFRC ratings. Our ENERGY STAR® certified units are available with select glass options.
Did you know:
Our Fibrex® material frames and sashes contain 40% reclaimed wood fiber by weight—much of that comes from Andersen Corporation’s wood-window manufacturing process.
Renewal by Andersen and its parent company, Andersen Corporation, were the first window companies to receive the SCS Global Services Indoor Advantage Gold™ certification. This certification is the most rigorous indoor air emission standard in the United States and meets the California Section 01350 Specifications.
