A plasterboard on its own does not give a fire resistance rating. It is the whole combination of products in a Siniat partition system which provides the fire resistance.

For Siniat Fire Board, on our typical Siniat C-Stud framing, a single 15mm layer each side of the stud frame achieves 60mins fire resistance (insulation and integrity) and 2x 12.5mm layers each side achieves 120mins, see our system selector for more performance information.
