Hello
I need to fit a fire door frame between a living area and a garage.
I've picked up a frame but cant understand why the fire door frame is 40mm taller than standard frames? I know the wood is slightly thicker but doesn't account for 40mm.
Also do you need a intumescent strip at the bottom on the cill? Are there any special requirements regarding the cill ?
Thanks all
