5 Important Facts About Fire Door That You Should
Know

What is Fire Door?
Buildings are compartmentalised to delay the
spread of fire from one area to another. These
compartments are usually linked by fire doors to
allow the flow of traffic around the building.
Fire doors have two important functions in a
fire when closed they form a barrier to stop the
spread of fire and when opened they provide a
means of escape. So, having a proper fire door
inspection is mandatory.

How are fire doors different to normal doors?
Fire doors are manufactured to withstand the
spread of fire for a given period of time,
normally a minimum of 30 minutes. This allows
time for inhabitants of a building to escape.
Fire doors may be of solid construction or made
with a special core, often flax board or a wood
composite material that is slow to burn. They are
also made with special seals, fitted into either
the door or frame, which seal the door on impact
with heat, to stop the spread of fire and/or
smoke around the edges of the door.

How do I know if I need a fire door?
Fire doors are mainly used in commercial
buildings, such as hotels and offices but are
also mandatory in some domestic homes, depending
on the country specific building regulations. You
therefore need to check your building
regulations. The majority of fire doors are
fitted internally but in certain situations they
may be required for external use, such as a
sheltered passageway. The regulations are there
to stipulate the legal requirement for fire
safety.

Can I choose any style of door as a fire door?
Many doors are available as fire doors, so there
is a huge choice of designs including many
finishes and glazing options. Fire doors are
commonly sold as a complete 'set' including the
frame and essential ironmongery, that holds the
door in place in the event of fire. This is often
a safer solution as the 'door set' should have
been tested to ensure all elements are compatible.
6
Is there anything different about installing a
fire door?
Yes.  A new fire door is a life-saving product
and must be fitted correctly. The installation is
critical to the door's performance in the event
of a fire. Fitting instructions would normally be
supplied with the door and it is essential to
follow these instructions and to check that any
elements used are compatible including the
correct seals and ironmongery.
7
How are fire doors tested?
 There is a legal requirement for fire door
manufacturers to prove that their doors perform
as claimed. This is usually done with an
independent third party testing company. A 'door
set' is built into a suitable construction on a
furnace and a real fire test is conducted to
determine the period of resistance, 30 minutes
etc. This test provides the evidence for this
particular 'door set' construction.
