Guest Tony Posted July 4, 2023 Report Share Posted July 4, 2023 In our block of flats the corridor doors which are fd30 have had 20mm fire seals put on them recently to upgrade. I read that the seals should be 15mm. Does this mean that the door is no good? Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted July 6, 2023 Report Share Posted July 6, 2023 The product data sheet for the particular model of door leaf will provide information about the exact fire seal requirements. Generally speaking a firmly closed fire door is unlikely to be adversely affected by having seals that are 5mm wider that those specified.
