What is more important in saving energy, the frame or the glass?
Since 80% of a window is glass, real heating and cooling savings come from what is known as “improved glass performance,” not a high R-value on the frame. Thermal Advantage uses the latest technology, known as a high performance warm edge spacer system. This spacer system helps to improve the performance and the longevity of the insulated glass unit, and is standard on all Thermal Advantage windows.
The glass is the most important factor in energy efficiency as approximately 85% of a window is the glass. WeatherGard uses the latest technology, incorporating the Superspacer® warm edge spacer system. This state of the art spacer system has a no-metal design, which reduces condensation forming on the window, thereby minimizing mold growth. Furthermore, WeatherGard windows are manufactured with energy efficient, 7/8″ thermal-pane glazing with double strength glass which provides superior thermal performance. The patented titanium Low-E glass we offer is standard in all of our windows and is designed to keep your home comfortable year round. WeatherGard’s titanium Low-E glass works by sending heat back to its source. Therefore, in winter, the low-E glass keeps the heat generated by your home’s heating system inside your house, and in the summer, it keeps the heat generated by the sun from entering your home. This results in a more home as well as reduced heating and cooling costs. Low-
