Bay Window vs Bow Window: Key Differences for Knoxville Homes

The Core Difference Between Bay And Bow Windows

Bay windows and bow windows both add depth and light to a room, yet their shapes, structure, and costs are not the same.

Most bay windows are built as a three-panel unit, which gives the exterior a sharper, more defined projection.
