There are several types of French doors perfect for any number of different applications:

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 elements 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 wood choices.

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.

Bifold French doors. A bifold door is a unit that has two to four sections that fold in pairs. Each door does not usually exceed 6 feet in width. The doors can open from either side or from both sides. Bifolds are most commonly used for closets.

Multifold 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. 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 of 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 for sliding French doors.
