Guest Ross Posted March 14 Report Share Posted March 14 Can a FD30 fire door blank be installed in an old softwood frame if the frames are 30mm thick and over 70 wide. I’ve been asked to install a door and the manufacturer of the door states the frame has to be at least these dimensions. Would it matter if the frame is old?

Mike North Posted March 18 Report Share Posted March 18 As long as the frame meets the minimum requirements in the manufactures installation instructions then yes Quote Link to comment Share on other sites More sharing options...
