The Glass

Our High-Performance insulating glass is 35 percent more energy efficient than ordinary double pane windows in winter; 41 percent more in summer. Our special Low-E coating allows light to enter your home, but inhibits the passage of heat. So, if it's 0 degrees outside and 70 degrees inside, the temperature of the innermost glass pane is a comfortable 57 degrees.

The Seal

Our windows and patio doors seal shut to some of the tightest tolerances in the industry, minimizing drafts, dust, and water infiltration. The closure and thermal performance, along with our High-Performance insulating glass, help make us one of the world's most energy efficient windows and one of the first window manufacturers to be included in the EPA/DOE ENERGY STAR windows program.

The Warranty

There's no other like ours, because it's non-prorated and it's fully transferrable. Plus, we give you a 20-year warranty for glass (five years for impact-resistant glass) - 10 years for other components - that's backed by over 700 service representatives nationwide.
