A fire door is one that’s specifically designed to do this effectively. They can be placed throughout your property, dividing the entire building into compartments and thereby providing its occupants with time to escape. Fire doors form part of a building’s passive fire protection system – and they play as important a role as active components like smoke alarms. Your building’s planning regulations will dictate which doors will need to be fire doors.
Before they’re shipped, a given model of fire door must be subjected to a special test of its efficacy. During this test, the door is equipped with all the same frames, seals and hardware. To replicate the results of this test in the real world, then, a door must be kitted out with these same components.
Fire doors are rated according to the length of time they’ll hold a fire at bay. You can glean this information from the code attached to the door. ‘FD20’ describes a fire door that will repel a blaze for twenty minutes before failing, while ‘FD30’ will hold one back for thirty minutes. The fire doors we sell are all rated for thirty minutes. Of course, in the real world, these lengths of time might vary – especially if there’s some inconsistency in the way they’ve been installed. That’s why proper installation is essential.
The main point of vulnerability for any door is the gap between its edge and those of the surrounding frame. Hot air might be able to pass through these gaps, heating the door more quickly and causing it to fail sooner. Intumescent seals help to combat this. They’re special kinds of seals which expand in response to heat, forming a tight barrier through which hot air can’t pass.
