Andy Mack Posted November 7 Report Posted November 7 When a fire door has been fitted occasionally they do not close exactly flush to the door stop. May be warped Twisted Poorly fitted Water damage Structural movement And other possibilities. I know its 2-4mm max between leaf and. Frame but What is the maximum acceptable gap size between the header and the latching side of the door leaf? Cheers Quote
Neil Ashdown MAFDI Posted November 11 Report Posted November 11 Misalignment of the door leaf and door frame is a common issue. In terms of requirement of the installation to comply with product certification the door leaf must not stand proud of the door frame or if this is permitted there will be a very tight allowance, typically 1mm. As far as the door leaf being "off" the rebate stop, I have not yet encountered a limit for this issue and recommend where the stop is the planted type that it be moved to compensate for any twist in the door. For a frame with a rebate machined from the solid this would not be possible of course. To be correct, one should always check with the particular door manufacturer to see what is permitted in terms of tolerance for the door leaf to stop dimension. Quote
