A glass garage door can be a stunning complement to the clean-lined geometry of modern architecture. During the day, glazed panels allow abundant natural light to filter into the garage. Then at night, when lit from behind, the door almost seems to glow, transformed into a magical focal point on the home exterior. You can customize the tint and transparency of the glazing to control daylight and privacy. With a Clopay Avante Collection door like the one shown here, you can even customize the frame color.
