Andersen Corp. has released the first Environmental Product Declaration (EPD) for a U.S. window manufacturer. The independently verified document provides information about the life-cycle environmental impacts of the company's Renewal by Andersen Double-Hung window. 

The EPD addresses the cradle-to-gate lifecycle impacts of the window, which is made with Fibrex, a pre-consumer recycled material made of up to 40% reclaimed wood fiber by weight. Fibrex material is twice as stable and rigid as vinyl and has excellent thermal insulating properties, the company says.

Green building certification systems, such as LEED recognize and reward the use of products that have a published EPD.

“Publishing our first EPD is an important step in Andersen’s sustainability journey,” says Jim Weglewski, vice president of sustainability. “Increasing product transparency supports our ongoing efforts to produce durable, energy-efficient products that help customers reduce energy consumption, lower utility costs and reduce greenhouse gas emissions.”
