DENVER -- Winter may be behind us, but the chilly weather might be around for a while. Wouldn't it be nice if you could replace your windows and turn down your furnace at the same time?

Radiant Glass Industries, a Denver company, has developed a window that can actually heat your room and help you save money on your energy bill.

Richard Westgard's home in Golden is nestled in the foothills, where the wind often blows and the temperatures are colder than in Denver.

A recent remodeling project allowed Westgard to change the windows in the main living areas of his home. Westgard, like many homeowners, regarded the windows as the main source of heat loss in the home.

During a recent tour of his home, Westgard made specific reference to the large windows in his living room.

"It's cold to the outside and very warm to the touch inside," said Westgard as he touched the glass in the newly remodeled part of his home.

Not too long ago, the situation was very different in the room, he said.

"A year ago you couldn't even sit in the room without a roaring fire and the heat going," said Westgard.

Nobody in his family wanted to sit in the living room, although it had the best mountain views. It was always too cold. Westgard heard about Radiant Glass Industries in Denver and contacted the window designers.

"We've developed the technology to run electricity through the window and turn it into a heater," said Duff Stroumbos, a developer at RGI.

RGI used existing technology that can be found in grocery store freezer doors. The technology keeps the the store's glass from fogging up and can work to help home windows warm up.

"We were able to take the technology to the next level and make windows a clear heater that you can use to heat your building," said Stroumbos.

Stroumbos illustrated the technology from the design office in Denver. With an infrared heat gun in his hand, he placed it next to the Radiant Glass window. The temperature outside was about 30 degrees.

"The inner pane is now running at 104 degrees. So it is radiating heat into the building and is an inch away from outside where it is 30 degrees," said Stroumbos.

Low voltage wires, similar to those used for cable television, run between the glass panels and create a safe heating source. Developers at RGI say an average sized radiant glass window uses as much energy as two light bulbs.

"We're making the claim this is the most efficient, electrical heater on the market. And, it's a window," said Stroumbos.

RGI is now hoping to provide this option to Colorado homeowners who are looking for a way to use less energy and be a bit green.

"You don't have to be a rocket scientist to lend yourself to some support for helping out with the energy crisis we have going on and to add some comfort to our lives," said Gino Figurelli, a researcher at RGI.

At the Westgard home the furnace in the living room has not turned on once since he installed the new windows. It is now a literal hot spot.

"Now it's the most popular spot because those two windows are both heated and it's coming from two directions. It is unbelievable, amazing," said Westgard.

The Gadiant Glass windows will cost more than regular windows, maybe even twice as much. But the hope is that homeowners can save that money and much more in monthly energy expenses.
