Just as the roof over your head shelters you from the rain and sun, double pane windows protect you from winds while allowing natural light to fill a room. Windows play a vital role in your home’s energy performance, as its structure and seals prevent air leaks. Glass Doctor® of Knoxville offers insulated glass units, or IGUs, that help maintain the comfort levels in your home while conserving energy.

Double Pane Windows
A double pane window is a unit of insulated glass. The window has two panes of glass that are slightly separated and sealed using an insulating spacer. Glass Doctor Knoxville uses different types of insulating spacers, such as a warm-edge spacer called a “super spacer” or those filled with desiccant materials that absorb excess moisture.
To prevent condensation and moisture from forming between the glass panes, glass specialists use a high-grade sealant. They may also fill the space between the two panes with krypton or argon gas to further insulate the glass.
Double Pane Glass Windows to Lower Energy Bills
The insulated glass in double-pane windows reduces heat transfer in a home. This means that they help prevent the escape of warm air in your Knoxville home during the winter. During the summer, the windows help maintain the cool temperatures in your dwelling and reduce heat gain. In addition to maintaining comfortable temperatures in your home, windows with insulated glass reduce the load on your heating and cooling system, keeping your energy costs low.
Double Pane Window Replacements
When double-paned windows have a broken seal, you may notice condensation or fog-like moisture between the panes of glass. Fortunately, you may not have to purchase a new window in such a situation. At Glass Doctor of Knoxville, our glass specialists may be able to replace the insulated glass and install new seals in your existing window frame for less than the cost of a new window. They may also be able to repair chips or cracks in single-pane windows.
Glass Doctor of Knoxville will work around your schedule when you need home glass replacement services. If you want to upgrade the windows in your home with insulated glass, we offer a variety of options that may help reduce your power bills and increase your home’s value.

Josh Hensley4.8/5 -
I had work done around November 23 2025. The work that was done was definitely to my satisfaction. Being an over the road truck driver and owning my own semi truck it is hard to find any glass company that will work on them. Called these guys and they said come on in and we will take care of it. Sure enough when I got there two guys got right on it. They spoke, worked and did the job in a very professional manner. To my experience with how much it costs for work to be done on semi trucks, I feel it to be a very reasonable price. Thanks again guys and sorry for the late review.
