Awning Windows

In Windsor, awning windows are a great choice. They hinge at the top and open out from the bottom, which is perfect for letting air in, even when it’s raining. These windows are great for higher wall placements, offering both light and air without compromising privacy. Plus, they’re easy to use and energy-efficient, making them a smart and stylish pick for any home.

Bay & Bow Windows

Bay and bow windows bring a stunning architectural touch, extending out from your home to create wide views and a sense of more space. In Windsor, these windows are popular for boosting a home’s visual appeal, offering wide outdoor views and extra indoor space, perfect for a cozy reading spot or displaying decor. They’re excellent for rooms where you want lots of natural light.

Casement Windows

Casement windows, which open outward like a door, are a favorite in Windsor for their clear views and great airflow. These windows are especially good for places where you want to let a lot of air in from top to bottom. Casement windows seal tightly when closed. These windows are energy-efficient and a good choice for saving on energy bills. The design fits well with both modern and traditional homes.

Sliding Windows

Sliding windows, moving horizontally on a track, are a functional and stylish fit for Windsor homes. Great for places where windows that open outwards aren’t practical, they’re easy to operate, need minimal upkeep, and have a modern look. The large glass areas also let in plenty of light, making rooms feel more open.

Double Hung Windows

Double hung windows, with two sashes that move up and down, are versatile and fit many home styles in Windsor. These replacement windows offer flexible ventilation options and are easy to clean, as both sashes can tilt inward. This classic window style also helps conserve energy, making double hung windows a practical option for homeowners.

Picture Windows

Picture windows are ideal for Windsor homes that want to capture stunning outdoor views. These fixed windows offer broad, uninterrupted views and bring in lots of natural light. Often used to create a visual focal point or to frame a beautiful outdoor scene, their energy efficiency and customizable sizes and shapes make them a top choice for enhancing your home’s interior and exterior.
