Hello The school i work in was built over 40 years ago and still has the original fire doors. A company was appointed to assess the doors and failed them all because they had no lables/plugs. They recommended that they all needed replacing. I'm no expert but can these doors be listed as nominal fire doors as long they have a solid timber core? What would be the other conditions? Am I right in saying: - 3 hinges of fire resistant construction - fire and smoke seals - no damage to the door - suitable frame and no excessive gaps If some of the doors have deficincies can they be upgraded, for example changing the hinges, adding smoke/fire strips, increasing the size of the rebate on the frame? If so, what qualifies a person to carry this out? Finally, if the gap beneath the door is greater than 10mm and there is no smoke seal can a hardwood strip be glued/screwed to the bottom of the door to reduce the gap? Thanks in advance.
