Hello,
I am planning to change my current living room door and I am struggling to find information on what are the requirements for the new assembly to be fire rated.
The existing door is single leaf and it opens into the living room. At the top and sides of the existing frame there is a rebate which the door closes against. Outside the living room is a corridor which leads to the main exit door of the flat (second floor stairs).
I would like to make the current opening wider and install two leaves, one leaf to be 838mm wide to open into the living room plus a 533mm wide side panel which (if opened) would open into the corridor (not to clash with furniture in the room). Also, due to limited ceiling height, in order to fit standard size doors on the market I will need to change the frame too (I believe current door was cut from previous owner).
Considering I will have a new frame and two new leaves opening in opposite directions, what are the minimum requirements for the system to be fire rated? What do I need to specify to the carpenter?
Because of the two leaves opening opposite directions, it will be difficult to have a continuous rebate to the top of the door. Do I need a rebate or can I just have intunmescent strips?
Please help, thank you!
Joana
