The ENERGY STAR® Sustained Excellence distinction is reserved for ENERGY STAR partners demonstrating outstanding leadership year after year. The 2013 Sustained Excellence Awards are given only to organizations that have been named ENERGY STAR Partner of the Year for three or more consecutive years.
For over 100 years, Andersen has built a reputation for environmental stewardship and energy-efficient products. In fact, Andersen has been part of the ENERGY STAR program since it started, and was the first window manufacturer to be named an ENERGY STAR National Window Partner of the Year in 1999.
Which is why, when you choose Andersen windows and patio doors, you know you’re getting energy-efficient products that help reduce the transfer of heat, so your house requires less energy for heating and cooling. And since the durability* of Andersen products reduces maintenance, painting and the need for replacement, they help save resources and energy in the long run.
Andersen. Committed to being good stewards of the environment. And committed to you.
