A Fire Door is a type of door or movable barrier used as part of a
passive fire protection system within buildings to prevent the spread of
fire or smoke between separate sections. It is usually the only means.
Fire Doors maybe made of a combination of materials such as:
Timber
Steel
Gypsum
Calcium Silicate boards
Glass Sections
Apart from the door leaf (the swinging panel of the door) there is the
door frame which also has to meet fire rated regulations, intumescent
strips, smoke seals, door hardware and the structure that holds the fire
door assembly in place. Together, these components form an assembly,
typically called a door set which holds a rating, in hours, specifying
the amount of time it is able to resist a fire at a given temperature.
