JohnSur Posted July 3 Report Share Posted July 3 Hello, Had a question asked to me regarding adding smoke/intumescent seals to already fitted fire doors. These fire doors don't have any seals currently fitted and need to be brought up to standard. What would be the case for the best way to do this? Just cut grooves into the fitted doors and install the appropriate seals whether FD30 or 60 and reinstall? Also what would be the best way to fix the seals. I've seen some recently that don't look too good, some have been nailed in, some have been stuck in with weak glue and the strips are popping out. So wanted to know best procedure for now on. Any advice would be helpful. Thanks, John Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted July 3 Report Share Posted July 3 First thing to check is that intumescent seals are not already fitted, concealed behind the lipping of the door leaf. Once you've checked that seals are actually required you could remove the door and then router grooves around the top and vertical edges of the door leaf and fit the seals tight and flush within the grooves. Seals are self-adhesive and must be an intimate fit in the groove so you won't need adhesive or pins. Do not mix different types of seal.

Much appreciated Quote Link to comment Share on other sites More sharing options...
Mike North Posted July 4 Report Share Posted July 4 How old are the doors? they may not need strips if the door stops are 25mm. (but they will be old doors) Quote Link to comment Share on other sites More sharing options...
