With roots dating back hundreds of years, bay windows are nearly ubiquitous today, in part because vendors like JELD-WEN have introduced options in grilles, clad color, and glass as well as ENERGY STAR-qualified features to suit every budget and aesthetic. But bay windows' popularity is due to more than modern innovation. The style offers many compelling advantages. Because they project outward, bay windows add volume to the home. Plus, because they capture light from three exposures, bay windows make the most of the sun all day long and throughout the changing seasons. But most of all, homeowners embrace bay windows for the panoramic views they afford, which encourage a feeling of unity with the outdoors.
