® Atrium is one of the most vertically integrated window and patio door manufacturers in the world. Our philosophy is simple: to provide our customers with energy-efficient, maintenance-free products that help to lower their energy bills. But we dont stop there. Many of our windows have extended life cycles, which helps to keep them hard at work saving energy in Americas homes. From our environmentally sensitive manufacturing processes to our recycled content, our goal is to produce high-performance windows that meet or exceed current energy-efficiency standards. With Atrium high-performance window technology, you can have a proven solution to resist the suns heat in summer - and welcome it in winter. How do we do it? Our warm-edge glass sealant systems insulate the window frame and edge of glass up to 50 percent better than roll-formed metal spacers and up to 90 percent better than aluminum spacer bars. Our low-E glass includes up to three layers of a thin silver coating that allows ample visible light to pass through, while blocking infrared and ultraviolet radiant solar energy. The result: Cooler rooms in summer and warmer rooms in winter. Argon insulating gas, fills our double-pane window and door products. Greener Commitment ATRIUM COMPANIES OVERVIEW
