June 27, 20241 yr comment_43479 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 Report
