French doors are also referred to as French windows because they were first used as oversized windows opening out to balconies, characterized as having a lot of glass.

Their glass portions have also improved throughout the years, today fitted with advancements like, low-emissivity coating and multi-pane construction, to offer better function on the overall.

Depending on what is preferred, a French door can come in either a hinged or gliding configuration. Hinged French doors can also be made to swing in or out.

For many homeowners, French doors are attractive because they offer incredible aesthetic appeal, creating a brightly-lit, space-expanding effect in the home. The large amount of glass surface the door has not only lets light in but also contributes to the illusion of space by allowing you to see beyond the door even when the door is shut. This leads to a seamless connection between indoor and outdoor spaces in your home.

But while French doors will indeed give your property an aesthetic boost, they are also more than capable of improving function in the home. For instance, letting in a lot of natural light lets the door support daylighting efforts, reducing your dependence on artificial light during the day.
