There are several aspects of glass that influence performance including the number of panes and their coating. Energy-efficient windows use two or three panes of glass to increase the insulating space between them. A virtually invisible Low-E coating is applied to the glass to help reflect heat and keep your home comfortable. Coatings are also used on different types of glass to optimize them for various locations.
Our vinyl windows and patio doors are engineered with air chambers inside the sash and frame reduce heat loss and sound transmission to keep your home quieter and more comfortable year-round.Explore Vinyl
That's why we test our products to help ensure our designs will withstand the test of time. We tried to count the number of quality checks that we do in a typical hour, but we had to stop at 7,502 to get back to work.
A specially designed chamber tests for air, water and structural performance. There is a separate set of conditions for the three tests and the testing simulates positive and negative wind loads.
An infrared camera visually shows the efficiency of our glass. We compare dual-pane glass with no coatings or argon gas to dual-pane glass with Low-E coating and argon gas.
To test how sealants perform, glass is placed in a chamber at 140 degrees Fahrenheit with 100% humidity. It is then moved to another chamber, that simulates ultraviolet radiation, and back again.
A Sound Control performance package with varying glass thicknesses helps ensure that a lawnmower and the neighbor's barking dog doesn't wake you.
