Bay Windows

Replacement Windows Appleton, Green Bay, Clintonville, and Madison, WI

Bay windows instantly elevate your home’s style and create additional space all without the cost and hassle of a full room addition.

A bay window extends outward from your home’s exterior wall, forming a three-dimensional space that adds depth, light, and architectural interest. Typically made up of three window units (a large center picture window flanked by angled casement or double-hung windows), bay windows are a timeless choice for homeowners looking to enhance both curb appeal and interior charm.

Our bay windows are custom-built to fit your existing opening and available in a wide range of configurations. Whether you prefer operable casement sides, traditional double-hungs, or fixed picture windows, we’ll help you design the perfect setup to meet your style and performance needs.

As with all of our window styles, AHT’s bay windows feature a composite frame that’s 400% stronger than vinyl, plus a high-performance 1 1/8″ insulated glass unit filled with krypton and layered with 22 coatings of Low-E offering superior thermal performance built for Wisconsin’s climate.
