Energy Efficiency

Replacing your old windows and doors with new, energy efficient models from Renewal by Andersen® will make a big difference in your monthly energy bills. Here’s how:

Renewal by Andersen® is the leading manufacturer of energy efficient windows and doors in the U.S. But our commitment to environmental responsibility goes far beyond helping homeowners save money every month. Our manufacturing processes themselves are performed in environmentally responsible ways, using recycled materials and never wasting what need not be wasted.

The prime example of our efficient manufacturing process is our production of Fibrex® material. This wood grain and thermoplastic polymer is more sustainable than any vinyl or fiber cement material available. It is even efficient in the manufacturing process. Any excess material from one production gets recycled right into the next one. That way waste material isn’t disposed of in landfills like the majority of manufacturers who create vinyl products.

Using our exclusive Fibrex® material, we create doors and windows that keep costly energy trapped inside their home. Our High-Performance™ Low-E4® glass, which limits penetration of both UV and IR light, works with our Fibrex® to help homeowners get a superior level of energy efficiency from Renewal by Andersen® products.

For more information about our energy efficient replacement windows and doors we offer, please contact us today to schedule a design consultation, completely free of charge. We also invite you to visit our showroom in Austin, Texas, to see the quality, durability, and beauty of Renewal by Andersen® windows and doors for yourself.
