Door closers play a role in security at building entrance doors, closing doors once somebody has passed through and re-latching the door lock.
In buildings that require noise control (Studios) door closers play an important part in the suppression of unwanted noise both in and out rooms and the buildings themselves.
Door closers are most commonly installed on bathroom doors, fire doors, and exit doors in commercial buildings. During a fire, any door that penetrates a firewall must be fire-rated. Fire doors need to be closed in case of fire to help prevent the spread of fire and smoke. Any fire doors which are normally held open must automatically close and lock when a fire is present in the building.
Some closers incorporate a back-check facility which prevents the door from being opened too fast; this is useful for exterior doors where there is a danger of wind catching and blowing it open, potentially damage to the door, nearby objects, or people near it. The speed at which the door closer closes the door may be adjustable by up to three adjustment valves. These valves often adjust the sweep speed and the latch speed of the door and some closers are optioned with a delayed action valve.
