Ronan Posted July 30 Report Share Posted July 30 Hi, I am thinking to fit something like surface mounted intumescent strips or surface mounted intumescent fire & fire/smoke seals over the hinges and the latch area, because I don't understand how smoke wouldn't pass through those. I wanted to get your expert opinion: is it a good idea? Bad idea? Useless? Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted July 31 Report Share Posted July 31 There are better ideas: For FD30 doors the intumescent seal may be interrupted at the hinge positions (3 @ 100mm) and single lock/keep. For FD60 one of the twin the intumescent seals can be located to by-pass hinges due to the extra thickness door leaf. For smoke sealing use a seal that is attached to the door frame rebate stop, therefore continuous without interruption. Quote Link to comment Share on other sites More sharing options...
Ronan Posted August 1 Author Report Share Posted August 1 Thank you @Neil Ashdown MAFDI, do you mean something like this? https://envirograf.com/product/surface-mounted-brush-smoke-seals/ I can look into it, I understand how you would fit it at the hinges side, but how would you install it on the latch side? I also understand that this is a better solution based on your expert advice, but if I installed something like Surface mounted intumescent fire & fire/smoke seals at the hinges and latch, would it be better than nothing? https://envirograf.com/product/surface-mounted-intumescent-fire-firesmoke-seals/ Quote Link to comment Share on other sites More sharing options...

Neil Ashdown MAFDI Posted August 3 Report Share Posted August 3 These fit to the door frame rebate stop so that the flexible seal compresses when the door leaf closes against the stop. Quote Link to comment Share on other sites More sharing options...
