All, I've got to fit a 30 minute fire door on a property that's rented to a Housing Association. I've worked out what door to get and from where. However, I'm a little unclear as to what other bits have to be in place for the door to pass it's test, so as to speak. So, my questions are.... 1) Hinges I'll be using the special recommended ones - however, is there a legal requirement to have 3 hinges per door? Or will 2 be sufficient? The door in question is 78" X 30" and will be less than 40kg in weight. 2) Frame. Can the existing door frame remain, or will I have to have it replaced with a special one? The door is 44mm thick, so if the existing frame is 44mm deep, than can I just leave it in place? 3) Door closers The door has to auto-shut. I have a choice of 'Sprung closers' which are surface mounted and very easy to install, or 'Radius Plate Concealed' which are like a 6 inch long, 1 inch diameter tube that's fitted on the inside the door. I'd prefer the former - does anyone know if legally they are acceptable ona fire door? 4) Intumescent strip How exactly is this supposed to be fitted? 5) Paint Can I use normal paint on the door, or is there some kind of regulation regarding this too? Many thanks in advance.
