Made from a combination of materials, fire resistant doors are constructed using a number of components. The door itself, the frame and the hardware attached to the door all help to act as a barrier to fire and smoke, preventing it spreading.
Doors have a fire rating, which establishes how long a door can resist fire before breaching. Complying with regulations, fire doors resist fire for a limited amount of time. The integrity of the door will be determined by the quality of the components involved.
The intumescent strip – sometimes called a seal – is just one of the key components in a fire door. Running around the edge where the door meets the doorframe, it helps to trap the smoke in the area, preventing it from spreading, as well as assisting in keeping flames from spreading beyond the door.
The strip also expands when there is a fire, providing extra protection by filling out the gap around the door. With low friction fibres, the seal can also aid in the door closing effectively to form the seal.
Fire resistant doors create a passive fire safety system, protecting commercial buildings from the spread of fire by confining it to a specific area for a longer period of time. This allows people within the building enough time to escape via alternative routes which might otherwise be cut off by fire.
They are a legal requirement for particular buildings, including for flats and commercial property, but the prime purpose for fire doors is to save lives and halt the progress of a destructive fire.
Fire doors in new buildings are required to meet regulations on the following:
There are many aspects to the responsible person’s duties for commercial premises when it comes to fire safety, with the inspection and maintenance of fire doors a vital part of regulations for existing buildings.
The amount of time a fire door can withstand a fire is key to how well it will do its job. The longer a door resists, the greater chance there is of everyone in the building being able to escape.
Designed from a number of different materials and varying in density, there are some specific ratings for the integrity of a fire door. The BWF (British Woodworking Federation) provides the certification for these ratings.
Fire doors are tested from both sides to gauge the integrity and stability of the door during a blaze. Doors with an FD60 rating or higher are generally not used for escape routes, they are usually recommended for containing a fire or preventing it from reaching high risk areas which a company may wish to preserve.
