Thank you so much Neil and Anthony, I will loom at the link and think further.

Hello, Our building inspector has asked us to upgrade several door sets to FD30 in our 1909 house. For most of these I would much rather do this by upgrading the existing doors to nominal Fd30 doors and am confident that I have the practical skills I need. A previous inspector had said this would be fine and that there would be a straightforward solution for our doors. The problem I have is that the doors are all a little over 30mm thick. Why are nominal doors normally required to be 44mm thick or more? Is the requirement for a nominal fire door to be 44mm thick or greater an absolute rule, or is there a way round this? Thanks in advance Peter
