The ENERGY STAR^® Window Program is a voluntary partnership between the U.S. Department of Energy and participating window manufacturers. ENERGY STAR^® performance requirements are tailored to fit the energy needs of the country’s different regions – northern, central and southern states. Your investment in ENERGY STAR^® windows will pay for itself over time, and then the savings is money in the bank every year! 

You’ll be doing your part to help the environment. In fact, if all households and businesses bought ENERGY STAR^® products for the next 15 years, our national energy bill would be reduced by approximately $100 billion. The reduction in carbon dioxide emissions would be equivalent to reducing gasoline consumption by 120 billion gallons, taking 17 million cars off the road, or preserving 142 million acres of trees for the next 15 years.*

By choosing GrandView™ windows, you can cut your heating and cooling costs, help make your home more comfortable and reduce air pollution – all without sacrificing versatility or style.

*ENERGY STAR^® qualification is based on NFRC certified product ratings.
