Renewal By Andersen Replacement Gliding Windows - Glass
You may not be able to see the difference in the glass we design, but we promise you'll feel it. Renewal by Andersen uses High-Performance™ Low-E4™ glass as standard in every window we build. This microscopically thin, metallic coating on the inner surface restricts the flow of radiant heat, helping keep your home warmer in winter and cooler in summer. It helps reduce ultraviolet and visible rays, while providing a clear, non-tinted view.

Our glass also uses a patented, low-conductivity spacer made of stainless steel that resists heat transfer much more effectively than the aluminum spacers used by many other manufacturers. An Argon gas blend is sealed between the glass to help inhibit the transfer of energy (heat or cold).
