Fire Resistance, Means of Escape And Access
The floors, walls and doors in your house and Loft/Attic conversion must be able to resist fire for a specified amount of time (this is usually 30 minutes). The aim of the requirements is that there should be a fire protected path from the conversion to the outside.
Under previous requirements a low level window and ledge were to be installed in the Loft/Attic as a means of escape and self closers were required on the doors. It has now been deemed that escape via the Loft/Attic is too dangerous and the main escape route should be through the house.
The main stairway should be protected by installing fire rated doors on both storeys, self closers are no longer required for most houses. Fire doors may not be required for non inhabited rooms such as bathrooms and cupboards if they are deemed a low fire risk.
