Since 80% of a window is glass, substantial heating and cooling savings come from improved glass performance. Our combination of UV-filtering Low-E glass (LG), insulating argon gas and the Intercept™ warm edge spacer system creates significant energy efficiency. Together they can cut the damaging effects of the sun, which can lead to faded carpets, curtains and furniture.
The result: your monthly utility bills will reflect savings year round—and that should help make you even more comfortable.
In winter, a warmer glass temperature is maintained, increasing the R-value by an additional 104%. |
In summer, a 48% reduction in solar heat gain helps cut air conditioning costs. |
When comparing the two thermography images, the difference is obvious. The window on the left is a clear insulated glass unit. The heat transmittance, indicated by the green, yellow and orange colors from the heat scale, is far inferior to that of the window containing the Solarban® 60 Low-E insulated glass unit (right).
ENERGY STAR is a government-sanctioned symbol for energy efficiency, credibility, sustainability and cost-savings for the consumer. Window World offers many ENERGY STAR® qualified glass packages.

U-Factor measures the rate at which heat flows through an object. The lower your U-value, the less heat your windows allow through them.
R-Value determines how well the insulation inside your window performs. The higher your R-value, the better insulated your window is.
Window World of Central Illinois is located in ENERGY STAR’s North-Central Climate category. To maintain certification here, our windows and doors must maintain a U-Value of ≤ .30 and an R-Factor from 13 to 21.
Low-E glass is a type of glass that has been treated with a microscopic, metallic coating designed to filter certain types of light into your home. The glass blocks heat gain from the sun’s reflected rays in warmer months and allows warmth from the sun’s shorter rays to flow into your home during cooler seasons.
Our Intercept™ warm-edge spacer system is a new-age technology used to extend the shelf-life of window glass by reducing condensation build-up and edge-to-glass temperatures. Designed to seal in escaping heat, this spacer system is the most effective of its kind.
Argon is a colorless, odorless and nonreactive insulating property with extremely high density and extremely low thermal conductivity, making it an ideal agent for year-round comfort.
Energy-efficient windows and doors are a smart investment into your home. The payoff is not only significant, but also tangible. You’ll reap the benefits in comfort and cost, as energy-efficient products pay for themselves time and time again.
