allside recently invested more than a million dollars in the Intercept® spacer system. It's the industry's first computer-integrated, automated Insulated Glass fabrication process � the state of the art in "warm edge" window technology.
It's what to look for in a window
Intercept spacers improve the energy-saving ability of your windows by as much as five percent.
That can save you money over the years � especially in combination with optional Wallside features such as Low-E glass and argon gas.
A window without warm-edge technology just isn't as good
Intercept spacers improve a window's insulating value, reduce condensation, improve its structural integrity and help retain insulating gas. And with no shiny, distracting spacer reflection in the window glass, windows with Intercept spacers were judged better-looking by 61 percent of people in a demonstration survey in the Mall of America in Minneapolis.



Intercept spacers are made from a continuous piece of tin plate, precision bent and overlapped to join. There are no gaps in the corners to let insulating air escape.
