Hi
im in the process of building an extension and have a question regarding fire doors. Is the standard width 762mm for a fire door and if so what should the structural opening size be 840mm? What im trying to work out is what I need to buy frame and door wise any links would be appreciated? stud wall will be based on 75mm studs so total thickness would be around 100mm at a guess.
