For outstanding replacement windows and doors in Clintonville, Madison, Appleton, Green Bay and nearby areas, look no further than AHT Wisconsin Windows, a family-owned and -operated home improvement company that has served local residents since 1967. We understand the unique needs of Wisconsin homeowners and proudly offer products that are “built frozen tundra tested tuff” to withstand the frigid weather we often experience here in the Badger State.

Our attractive replacement windows are made with expanded polymer composite, which is 400% stronger and insulates 214% better than any vinyl window on the market. These triple-pane windows feature 2 low-E glass coatings and 2 chambers of proprietary blend gas, mix of gases including krypton and argon, which drastically reduce heat transfer into and out of a home. As a result, they are ranked as “the most efficient” windows by ENERGY STAR. Plus, our house windows require virtually no maintenance, so homeowners won’t need to spend hours sealing, staining, and painting them. The combination of durability, energy savings, and overall beauty mean there’s no better value in the window industry than our composite windows.
