A Stylish Enhancement for Your Home

Coastal Bay windows and Bow windows are the perfect way to create a dramatic focal point in any room. These windows project out beyond your exterior wall to create the illusion of additional interior space. They are ideal for adding dimension, expansive views and natural light into rooms – making smaller spaces seem larger.

Bay Window

Bay windows feature three window units, consisting of a larger center window with two smaller angled windows on either side, and are mulled at either a 30, 45, or 90-degree angle.

Bow Window

Bow windows are typically made up of four or more windows of the same size and shape, mulled at a 12-degree angle, resulting in a more subtle curve than a bay window.
