Similar to bay windows, bow windows are multi-window units that are designed to provide expansive, almost panoramic views and allow sunlight in from several angles simultaneously. However, unlike bay windows, bow windows typically consist of either 4, 5, or 6 window panels, all of which are operational. This configuration creates a slightly curved â€œwall of windowsâ€ effect that can make a room feel more spacious and provide breathtaking visual appeal.
