A French door is typically a type of door constructed using glass panes, which extend over its entire length. You may also hear French doors referred to as French windows. Technically, they function as both doors and windows and are ordinarily integrated into both interior and exterior spaces due to their high level of versatility.
French doors tend to be manufactured using light construction, and due to their simplicity and light, they can completely change the interior look of a home. They’re especially useful for opening up a space and making better use of a home’s existing natural light.
