A fire door is an important safety feature that stops the spread of fire and smoke within dwellings and non-dwellings. They’re designed to be installed correctly and regularly inspected and maintained for maximum effectiveness.
The main categories of fire door are FD30 and FD60, which provide 30 and 60 minutes protection from fire. They also vary in their size and any additional features such as glazing, which are used to maximise natural or shared lighting and increase safety and visibility for first responders.
What are the two types of fire doors?
Typically, they’re tested by the manufacturer using a test procedure that follows BS 476-22:1987 or BS EN 1634-1:2014. The test involves exposing the door to heat conditions that are expected in a fire, then assessing it for stability and integrity.
There are also some specific requirements for a Fire Doors Kent to meet, such as an air-tight seal on the outside of the door that can’t be breached by fire or smoke and a temperature-rise test that limits the amount of heat transferred from one side to the other. These tests are necessary to ensure that occupants have a way of exiting a building even when temperatures are high on the fire side.
The fire doors that you select should be certified by a third party certification body, such as the BWF Fire Door Alliance or BM TRADA. They should have labelling on them that indicates the certification and that they’ve been made in accordance with relevant standards for safety. They should also be inspected regularly, usually six monthly.
