Some of the styles we offer include Double Hung windows, Horizontal Sliders, Custom Shapes, Casement Windows, Awning Windows, Picture windows, and Bay and Bow windows. Each of these styles offers unique benefits and features, making it easy to find the perfect match for your home.

Double Hung Windows

Double Hung windows are a popular choice, providing a classic look and easy ventilation. Both sashes are vertically adjustable and interlock for improved energy efficiency. Cleaning is made easy with the tilt-in feature.

Casement Windows

Casement windows are a hinged design that opens outward with a fold-in crank handle for easy operation. They offer versatile ventilation options, opening up to 90 degrees or less for cleaning and air flow. The lever lock ensures an airtight seal for increased energy efficiency.

Awning Windows

Awning windows are hinged at the top and open outward, providing ventilation while keeping rain out. They're often placed above or below other windows for added light and air flow. With a sleek design, awning windows are a popular choice for modern or contemporary homes.

Bay Windows

Bay windows add natural light and space to any room with their projecting design, featuring an insulated head and seat board with a birch finish. Choose from double-hung, casement, or picture windows with a 30- or 45-degree projection. For a more curved, classical look, consider a Bow window with a shallower 10- or 15-degree projection using casement or picture windows.

Bow Window

Bow Window is a curved style of window that projects outwards from the wall, creating a rounded appearance. It's made up of multiple smaller windows, typically casement or picture windows, arranged in a curved formation to add natural light and stylish touch to a room. The shallow projection of a Bow Window provides a soft, elegant look.

Picture Window

Picture windows are large, fixed windows that provide an unobstructed view and maximize natural light. They're a great option for showcasing a beautiful view or creating an open and airy feel in a room. Picture windows are available in various sizes and shapes to fit any space and design style.

Horizontal Sliders

Horizontal Slider windows consist of two or three adjustable sashes that slide right or left for ventilation. With a smooth glide track and sleek frame, they provide unobstructed views and improved sunlight exposure. Ideal for areas with limited vertical space.

Custom Shaped Windows

Custom Shaped Windows are windows that are designed and manufactured in unique shapes to fit specific architectural or design needs. These shapes can include half rounds, quarter rounds, circles, hexagons, and many others. Custom shaped windows can add a unique and personalized touch to a home and provide an opportunity to incorporate unique shapes into a design scheme. They can also provide additional natural light and ventilation, as well as enhance the overall aesthetic appeal of a home.
