Information About Our Bay and Bow Windows

Bay windows project outward from the wall of the home. They create a feeling of extra space inside the room and create a larger viewing area of the outdoors.

Bay windows first became popular in the 1870s. Today, bay replacement windows are sometimes installed to achieve the Victorian feel of that era. Due to their versatility, Premium Vinyl Windows’ bay replacement windows are also installed for a variety of other reasons.
