A French door brings elegance and beauty to a room. With two operating panels and expansive glass, the French doors bring in light and expand the view. An exterior French door allows you to enjoy the beauty of nature with open views to the outdoors and allows easy access to a patio, deck, pool or other outdoor space. You can also install a French door inside your home for a graceful transition between rooms. Interior French doors are great for maintaining visual openness to connect living spaces while also providing a functional boundary when you need it.
