Hello, The fire door survey for our building has been done and tells us that all our riser cupboards and communal doors now have to be smoke doors now with smoke seals added and the gaps at the bottom reduced to 3mm. It is a 20 year old block and the doors have flat fire strips in them and gaps at the bottom of around 6-8mm. Why now, after all this time do they suddenly have to be smoke doors? They said Approved Document B of the Building Regs states all fire doors in residential blocks should be smoke doors, but I thought this document was for new builds or big changes to buildings - not repairing existing fire doors. Any thoughts would be appreciated! Regards, Jan
