I need to provide a 60 min fire protection between my public house and living accomodation above. The floor between consists of 225 x 60 timber floor joists at 400 mm centers, timber tongue and groove floor boards, Lath and plaster ceiling which has at some time had timber battons and 12.5 plasterboard fixed to it . I proposed to overboard the ceiling with 12mm fireline board , coverstrips to joins and emulsion the fire board. ( would this give me 60 min protection ?? )
