Fire Door Flush Tolerance

Featured Replies

Hi

This is my first time on this forum, have have recently taken a BM Trada fire door installer registration, A question that i have been unable to Answer is to the flush Tolerance on fire doors ? can anyone help with this please. I have looked through the Manufactures installation details and ASDMA Installation Guidance but i cant see any Detail on this

You are correct Kevin, some fire door data sheets fail to deal with this issue.  Where this is the case the door leaf should not stand proud of the door frame at any point. Some fire doors have an allowance of 1mm proud - I am yet to see a more generous allowance.
