richardinnorwich Posted June 27 Report Share Posted June 27 Hi all, looking at doing some upgrades to existing 'Nominal' fire doors that are flat entrance doors. Been looking at metal thresholds that have intumescent brush strips in them, a little bit concerned that the brushes will get worn down really quickly and require constant replacement. Has anybody used them/got any feedback on their durability/suitability Thanks, Richard Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted July 1 Report Share Posted July 1 Why not use one of these and if you still need a flexible seal, fit it to the door leaf? Quote Link to comment Share on other sites More sharing options...
