Door closers: why are they fundamental?

Both from an aesthetic and functional point of view, door closers are now part of fire doors architecture, by also contributing to the safety of the environment. Let's see together the main features of their use.

Door closers are increasingly being integrated into the architecture of fire doors to make them complete in terms of use and improvement of their aesthetics, but what exactly are they for? Obviously, the first factor this accessory is connected with, is the more comfortable and silent movement of the door that dampens the noise during its closing phase, but its use goes well beyond these two aspects.

DOOR CLOSERS: AN ACCESSORY DESIGNED FOR SAFETY

Fire door closers are daily strained to innumerable movements and, in addition to ensuring greater comfort during the use of the door thanks to the asymmetrical transmission, they contribute to the safety of the environment. In fact, during emergency situations such as a fire, this special accessory combines its own functionalities with those of fire doors and, while keeping the latter well closed, it creates a real barrier that prevents the fire from entering inside a room. Door closers are also indispensable for securing very wide fire doors that can reach a weight of over 120 kg. These heavy doors are extremely dangerous without a door closer that slows their run, since a sudden movement could seriously injure anyone crossing the threshold in that very moment.
