Where they cannot completely prevent a fire from spreading, it will certainly buy you a considerable amount of time, allowing the occupants of the building to safely evacuate, without coming to any harm. FD30 fire doors have been engineered and built to withstand a fire for a solid 30 minutes, whereas FD60 fire doors are able to prevent the spread of a fire for 60 minutes. Depending on the size and layout of the building, one type of fire door may be more suitable than another. ( source https://www.cityfire.co.uk/news/fire-doors-explained/#fd30-vs-fd60
