You and your family deserve to be comfortable in your home year round—and NOT have to worry about high energy bills. Timeless windows are as energy efficient as they are beautiful. Every Timeless product incorporating any of our high-performance glass systems qualifies for the ENERGY STAR® label. Timeless glass systems feature technologically advanced Low-E coatings, the industry’s most effective and accepted spacer system, and safe, natural, inert gases between the panes that also improve your windows’ thermal performance.
U-Values for aluminum, wood and typical vinyl windows were obtained from LBNL Windows W5 generic window components. Actual values may vary.
"U-Value" indicates the rate of heat flow that escapes your home when you want to keep the heat in. "Solar Heat Gain Coefficient" (SHGC) indicates the rate of heat flow that enters your home when you want to keep heat out.
With all Timeless Series windows, you can choose from numerous high-performance glass systems for just the right level of comfort and energy-saving efficiency—and security—that you prefer for your home.
