The first choice a homeowner will make is what style their patio door will be. There are two main types of doors, sliding patio doors and hinged (often referred to as French) patio doors. Sliding doors are perfect when space is tight. They don't swing, so they take up much less floor space.

Hinged patio doors create a dramatic design element. You can choose two movable doors that swing out and open from the center, or have the simple elegance of just one door, with or without stationary sidelights, giving you more furniture placement options. Newer options include bifold or accordion-style doors that give the impression of an open and indoor/outdoor living space. No matter which you choose, patio doors showcase your yard or deck by drawing the eye outdoors.
