Please could you advice on what type of fire door needed for a kitchen door to ensure if there is  fire, it  is contained in the kitchen?

Thank you kindly

A FD30 fire door if you wish to prevent fire breaching the door and a FD30s if you require cold smoke stopping as well. If the door is opening onto a protected escape route then you require a FD30s fire door if it is to prevent the spread of fire only a FD30 fire door should be satisfactory.
