Vinyl Replacement Windows Chicago

What Makes Our Chicago Vinyl Replacement Window The Best?

There are many vinyl replacement windows available in Chicago, but there are certain features that make Defender’s vinyl windows a superior product.

It starts by using pure, virgin vinyl. Because our vinyl is pure the color of our windows lasts longer and the strength of our windows is unmatched. The window is further strengthened by fusion welding all of the corners. Finally, the frame and sashes are reinforced with steel. This makes the window extremely rigid and results in windows that last as long as you live in your home.

Our vinyl replacement windows come with 7/8 in. insulated glass. By utilizing 7/8 instead of 5/8 we are able to create a wider space between the glass and offer a much more energy-efficient window. Options such as Low E and Argon Gas are also available to improve the energy efficiency of your insulated vinyl window.

In addition to providing an outstanding product, our installation process is professional with great care being given to the small details. All of our windows come with a transferable lifetime warranty, as well as a warranty on our workmanship.
