Door closers are an important element in residential and commercial buildings. Door closers are used to shut doors automatically, without any effort. They are mounted for two main reasons. First, door closers are a security constituent because they ensure that doors close whether human force is applied or not. Second, they help making sure that fire does not spread from one part of a building to the other or from one building to another building, during a fire emergency. A secondary cause to use door closers is to keep indoor air inside and outdoor air outside.

The first use of door closer is to maintain privacy. Whether at office or at home, people need their privacy to be maintained, and it gets a bit irritating if your door is left open by people coming and going out of your room. So, in order to maintain privacy and to guarantee no external interferences, people opt for the use of door closers.

Also, people usually are not in the favour of external noises and irritable sounds. A door closer will close the door as soon as someone comes in or leaves, so the sound that was present outside the door remains confined to the outside only.

Door closers are also used in providing security to homes. Homes that are designed stunningly, people need to secure them right from the entrance gates. So, even the entrance gates have automatic door closers installed in them, which open and close themselves as soon as a person or a car comes inside. Moreover, the entrance doors to the inside of the house are also guarded with door closers.

Door closers exhibit their highly beneficial use in case of fire doors. In a place where fire may break on an unexpected note, the door closers on fire doors can help in suppressing any possibility of the flames spreading out in the entire building out of that one room. In fact, most of the material used for door closers is fire repellent. When it comes to security of a household, trespassers and even burglars can face a lot of difficulty in breaking in because of the strong hold of door closers joined with door frames, barred with various codes.

Door closers turn out to be quite long lasting. Since grade one closers tend to last for quite a long period, they are fixed to some good traffic areas and can handle entrance as well as exits at such areas for about 400 times a day. Grade two closers are meant for moderate traffic areas and are therefore used mostly in offices. They can only function for around 50 to 100 times per day.

Door closers may be surface mounted door closers or concealed closers. Concealed closers may be concealed overhead, hidden within the doors, or hidden on the floor. A surface mounted door closer is a small box that remains attached to the top of a door with a mechanical arm extending from the box to the doorframe. In the concealed prototypes, the box will be hidden, with only the arm being visible.

Nowadays, door closers are also available with “delayed action”. They help the doors to remain open for a preset period of time and after that time span ends, they start closing slowly. This is a special type of door closer that is available for those families who have an old member or someone who uses wheelchairs.
