At Centennial Home Improvement, we offer a variety of modern window styles designed to enhance your home’s comfort, energy efficiency, and visual appeal. Each window type provides unique benefits and can be customized to fit your space perfectly.

Bay

Bay Windows

Bay windows feature a large center picture window framed by two smaller angled windows. This design projects outward to create a cozy nook or window seat. Bay windows invite natural light and add depth and character to your home’s interior.

Bow

Bow Windows

Bow windows consist of four or more panels set at equal angles to form a graceful outward curve. Similar to bay windows, they fill your room with sunlight while offering panoramic outdoor views. Their smooth design complements both traditional and modern homes.

Casemaster

Casement windows open outward on side hinges, operating easily with a crank or manual handle. Their tight seal reduces air and water infiltration, improving energy efficiency. These windows provide a sleek, contemporary look and excellent ventilation control.

Our Windows Can Make Your Home Greener
You can improve your home’s energy efficiency by choosing insulated glass packages for your replacement windows that will pay for themselves by providing year-round energy savings. Our windows help reduce heat transfer with Low-E glass that acts as a thermal mirror, a warm-edge spacer system that provides an effective thermal barrier, and argon gas fills that increase energy efficiency.
