Designed to fill standard bay openings while maximizing daylight and controlled airflow, this new five-pane window assembly measures exactly 115.5 inches wide by 68.25 inches high with a 20-inch depth extending into the room. The layout combines three fixed viewing sections with two operable crank units to balance structural rigidity with practical ventilation.

• Precise Dimensional Alignment: At 115.5W x 68.25H x 20D, the frame matches standard residential bay rough openings and eliminates the need for custom framing or drywall adjustments.
• Dual Crank Ventilation: The second and fourth panes utilize integrated winder cranks to tilt open for targeted cross-breezes or closed operation when rain or debris is expected.
• Sealed Stationary Panels: First, third, and fifth sections remain permanently locked to maximize unobstructed natural light, reduce moving-part wear, and maintain a consistent thermal barrier.

This configuration delivers reliable temperature regulation, easy maintenance, and a stable architectural fit that integrates seamlessly into existing wall structures. Install this accurate-dimensional bay window to improve room circulation and upgrade your property’s energy efficiency today.
