Interior French doors. These doors are made specifically for adjoining one interior room to another interior room. They function as a wall, to separate yet open up rooms in your house. Any standard interior wood can be used for an interior French door.
Exterior French doors. These doors are made specifically for exposure to the outside and are a wonderful way to bring natural light and views into your home. They are typically manufactured with tempered glass, which is stronger and more durable than glass used on interior doors. Mahogany, Spanish cedar, and white oak are popular choices for the wood.
Pocket French doors. Pocket doors, which slide into a wall instead of opening on a hinge, are great space savers. Pocket French doors allow for handicap accessibility for freer movement from room to room.
Bi-fold French doors. A bi-fold door is a unit that has two to four sections that fold in pairs. Each door does not usually exceed 6 feet in total width. The doors can open from either side for one pair or fold off both sides for two pair. Bi-folds are most commonly used for closets.
Multi-fold French doors. These are designed to be used where folding doors are needed to cover a wider than normal area. They are typically used as room dividers or hall dividers. Depending on the hardware used, door sections from 12 to 42 inches wide are available and can be used in any number of configurations as long as the doors are in even numbers on each side the opening.
Sliding French doors. With these, you no longer have to worry about where to place indoor or patio furniture in relation to the entryway. Balconies, where space is usually tight, are perfect opportunities for sliding French doors.
