Wrongly glazed fire doors, doors with no intumescent seals, and non-fire rated letter plates can cause catastrophic results as our latest video shows.
We put three FD30 (1/2 hour) fire doors to the test, simulating some of the installation and maintenance errors we often see during fire door inspections, or based on questions we are often asked.
The left hand door ‘A’ was incorrectly glazed using safety glass, with no certificated intumescent glazing system. Intumescent smoke seals around the doorframe were pieced together instead of using a continuous length on each side and across the top.
The right-hand door ‘C’ was installed with no intumescent smoke seals and had an ordinary letterplate fitted to it – simulating a front entrance door in blocks of flats.
The central door ‘B’ was correctly glazed and installed.
Watch our film to see how long each door endured the test – and see what happens when you get it wrong!
