IanS Posted May 1 Report Share Posted May 1 For a flat on the 3rd floor of a 4 storey block of flats. A door inspection found a 9mm gap under one part of the threshold drop down smoke seal. The flat is new and the developers contractor came and said there was no problem as the gap could be up to 10mm. The inspection report says it should be 3mm as the door has smoke seals. The inspection report matches my understanding but am I missing something? Quote Link to comment Share on other sites More sharing options...
Mike North Posted May 1 Report Share Posted May 1 The contractor is partly correct, the gap can be up to 10mm as long as when the door is closed there is a drop-down seal that touches the floor Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted May 1 Report Share Posted May 1 BS 8214: 2016 requires that a flexible threshold seal, where fitted, seals the gap. Alternatively, the maximum gap is 3mm. Quote Link to comment Share on other sites More sharing options...
