Guest HKR Posted October 23 Report Posted October 23 I am converting a commercial space into two duplex flats above a ground floor commercial space. It's a three story terrace. The top floor ceilings have been plasterboarded with normal plasterboard and skimmed. I assume this offers 30mins FR. Does this meet the regs? There is a mains smoke alarm throughout the whole building, including the loft space above this ceiling. My former builder fitted plastic loft hatches with no FR. Do these need to be replaced with FR hatches? If so, 30 or 60? Many thanks in advance. Quote
