Hi Marie, The doors are fire doors with smoke protection because building regulations (approved document B) say they need to be. When closed they should provide protection from fire and smoke spread so that in a fire somebody on the upper floor should be able to safely escape, passing a fire in a room in a lower floor, using the staircase.
Most designs of timber door are also available as FD30(s) fire doors. Fire doors are 44mm thick whereas standard doors are only 35mm or 40mm so you would have to alter the door frame accordingly. With this in mind and the fire and smoke protection issue I can't think of any reason to fit non fire doors instead.
All the best with your home improvements!
I have a 3 storey house built around the year 2000. All internal doors in the house are the same. The doors are 44mm think with 3 hinges, feel heavy and have percos. I am quite sure that they are the original doors, so would have complied with the building regulations at the time the house was built. They do not have any intumescent strips. I plan to add intumescent strips to them. The door stops and frames seem to be the correct specification for a fire door. Do you think that I can just add intumescent strips to make them FD30? Or should I consider getting new doors? My intention is to ensure that the house has FD30 doors, but I wish to determine if these existing doors are suitable for this. I cannot find any labels nor plugs indicating their specification. Along the top of the doors it says, "DALE 90623", which is probably the manufactures code for the style. However I have been unable to determine anything else about the door. I would be grateful for any suggestions.
