ENERGY STAR®

Products with the ENERGY STAR label are designed to use less energy, help you save money on utility bills, and help protect the environment. Renewal by Andersen® windows with High Performance™ low-E glass are ENERGY STAR compliant for all regions of the United States; see your Renewal by Andersen retailer for more information. An ENERGY STAR compliant product must be NFRC labeled and meet energy efficiency rating requirements. 15% of your total energy bill can be saved with ENERGY STAR qualified windows.

NFRC

In 1992 the National Fenestration Rating Council (NFRC) – fenestration is a technical word for windows and doors – established uniform tests and ratings to help homeowners make accurate comparisons among brands of windows. The NFRC label identifies a product’s U-factor – the ability to conduct heat. On a window, U-factor means how much indoor energy (heating and cooling) may be transferred through the window as a whole. A lower U-factor means better insulating quality. When comparing, keep in mind that some manufacturers present R-values, which measure resistance to energy transfer and often refer only to individual parts of the window such as the frame or the glass.

Andersen Corporation is a founding member of the NFRC, which includes product designers and manufacturers, builders, utility company energy specialist, government agencies and consumer advocates. Renewal by Andersen adheres to the rating system and proudly displays the NFRC label on our certified windows.

Green Seal certified

Renewal by Andersen windows have been awarded Green Seal certification. Green Seal is the national non-profit environmental organization that helps consumers, both individual and institutional, choose environmentally responsible products. Green Seal awards a “Green Seal of Approval” to products found to cause significantly less harm to the environment than similar products.
