[Reducing gaps between door and frame]

Thanks Neil, but it costs GBP218 to read that standard.  I will be contacting a local Fire Door installer and I am hoping he will be able to reposition the door leaf.  The door is 838mm wide and the frame spacing is 846mm so I am hoping that by packing the hinges the gap will be 4mm on each side.

[Reducing gaps between door and frame]

Hi - I wonder if this topic is still active.   The fire doors in our residential block have recently been inspected and all  of the doors have failed. The building was completed 2007-8 and presumably the fire doors would have satisfied the regulations of 2005.  The doors do not have any labels and according to the BWF web site would be regarded as nominal fire doors.  The doors were supplied as door sets - door leaf and frame. The doors are 44mm thick and are of solid construction and would be classed as FD30. The frames have intumescent strips, draught seals and smoke seals on the frame jamb.  The obvious fault with my own door is the  gap between leaf and frame. It is about 2mm on the hinge side and 5-6mm on the latch side, and about 5mm at the door head. The threshold gap is about 10mm.  Could this door be repaired and certified? I have attached two photos.
