John W Posted March 21, 2023 Report Share Posted March 21, 2023 I am replacing the intumescent seals on the firedoor frames of a small theatre. It seems when they were installed in 1997 the chippy cut bits out to accommodate the hinges, this cant be right. Do I need to relocate all the hinges to clear the channel for the strip or can I cut the strip either side of the hinges and fill the channel? The door sets came from Shapland, I can't find any data about them. Quote Link to comment Share on other sites More sharing options...
Mike North Posted March 22, 2023 Report Share Posted March 22, 2023 Most 30 min doors can be installed like this, it is only 60 and above where at lease one the strips must be continuous Quote Link to comment Share on other sites More sharing options...
