Ceiling plasterboard - standard or Fireline?

[Possom]

If having the ceiling plasterboard of a small 1st floor bedroom replaced I could use either standard plasterboard (£2.50 / M2) or alternatively I noticed there is a Fireline plasterboard product (£4.16/M2). The cost between these will be nominal for a small room.

Presumably the obvious choice is therefore the Fireline poduct? Any comments? Thanks.

Just over board the ceiling with 12.5mm plaster board.

The ceiling was a lath and plaster ceiling, though with damage to the plaster. The plaster has already been removed, with the laths remaining intact. The laths are currently holding up the loft insulation.

If the laths are level then double board the ceiling.

Double boarding is done for 1hr fire proofing, also helps with sound transfer.

Double boarding the 12.5mm Gyproc FireLine board gives 2 hrs of fireproofing.

After 2 hours of a house fire, you wouldn't have anything left.
