What Is a French Door?
A french door is a door style featuring large glass panes that run through most of its length, allowing maximum natural light and creating an open, elegant connection between indoor and outdoor spaces. It usually comes in pairs and swings open from the center. This classic design makes french doors a favorite for patios, living rooms, and modern architectural spaces.
What Is a French Door?
A french door is essentially a light-filled door with multiple glass panels—traditionally called “lites.” It was originally designed to bring daylight deeper into buildings, and today it’s widely used to elevate aesthetics, visibility, and ventilation.
They can be made from WPC, wood, steel, or aluminum, and are available in both inswing and outswing configurations depending on the space.
