If there’s an entry way in your business that handles two-way traffic, or where you need enough room for equipment or goods to pass through, a double door may be the solution. An exterior double door entry system may be useful for the front or back entrance to a building, or double doors may also be used in interior settings such as:
- Storage closets
- Conference rooms
- Hospital wards
Types of Double Doors
Double doors may or may not have a vertical mullion down the middle, separating the two panels in the frame. They may have one active leaf with a keyed lock and one inactive leaf, or two active leaves. Typically locking the active leaf keeps both leaves from being opened. A flushbolt may keep the inactive leaf in place until it needs to be opened to allow equipment to pass through. These types of doors are often used in corridors.
People sometimes wonder if it’s illegal to keep one of two double doors inactive, but it generally isn’t, since the other door can still be used as an exit. Knowing which door is active or inactive is important in the “handing” of a door, which refers to the direction of opening – push or pull. This issue of handing is crucial when installing the frame, doors and hardware. It’s also important for life safety codes that apply to the path of entry and exit.
You may also have double egress doors used in “cross-corridor” applications. With these doors the leaves swing in opposite directions so that traffic can flow two ways. Both doors may feature an exit device so that either leaf can be used. The doors can’t be described as active or inactive leaves, since there is no mechanical locking hardware on either leaf. Double acting doors, on the other hand, have leaves that swing in both directions, both in and out – like a saloon door. They’re often used in restaurant kitchens.
