Guest Mark Posted January 23, 2022 Report Share Posted January 23, 2022 Hi, I have just had an FD30 internal fire door installed between a garage and hallway. The frame of the door has been rebated a fitted by our joiner with an intumescent strip. There is a cold draught coming through the door due to a 3-4mm gap around the whole of the door (between the door and rebated intumescent strip). I have seen that there are intumescent strips with a single, double or triple fin that look like they could act as a smoke seal and draught excluder. Please may someone advise whether the installation of these would be recommended to solve my problem? If so, should I be buying an intumescent strip with a single, double, triple or a side fin? What would be this difference in installing one over the other? finally, would anyone know how many millimetres the fin protrudes out? Thank you!

Sorry, the 3-4mm gap around the door is more like 2mm Quote Link to comment Share on other sites More sharing options...

Neil ashdown Posted January 24, 2022 Report Share Posted January 24, 2022 (edited) Current Building Regulations require that a door between a dwellinghouse and a garage is a self-closing thirty minute fire door with cold smoke seals. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/937931/ADB_Vol1_Dwellings_2019_edition_inc_2020_amendments.pdf Appendix C Various types of smoke seals are available including bat wing, compression, combined intumescent with brush and combined intumescent with a fin or fins. There is guidance about selecting smoke seals for doors here https://www.ifsa.org.uk/documents/ Edited January 24, 2022 by Neil ashdown To add a useful link Quote Link to comment Share on other sites More sharing options...
