Bow and Bay Window Design

Bow and bay windows are similar in design however, there are a few characteristics that set them apart.

The typical bay window is angled with three windows and project about 3 feet away from the wall. Our uPVC Liniar bay windows come in multiple sizes but a standard bay window usually includes a large centre window surrounded by two smaller windows.

Bow windows are a variation of the bay window design and are made from various window units of a similar size that are joined together creating a softer, curved edge.

Our uPVC bow and bay windows can be installed throughout your home. Bedrooms and living rooms can especially benefit from their added light and depth. They can be internally or externally beaded and are available in either chamfered or sculptured profiles.
