French doors, also known as hinged patio doors, have become popular for their aesthetic appeal and how they bring light and openess into a home or room. French doors are characterized by their glass panels that extend from the floor to the ceiling, allowing for an unobstructed view of the outdoors. Some synonyms for French doors include double doors, patio doors, glazed doors, and sliding glass doors. Double doors highlight the fact that there are two separate doors that have the ability to swing open. Patio doors, like French doors, bring the outdoors in and make entertaining on a patio easy and convenient. Glazed doors simply refer to doors that have been fitted with glass panels. Finally, sliding glass doors operate horizontally, a characteristic that sets them apart from French doors.
