Plasterboard fire resistance

[lingmoor]

Hi

Can anyone point me in the direction of information relating to fire resistance of plasterboard.

I was in a tax office building the other day (yes I know ) where it appeared that one leaf of a 30 minute double fire door had been replaced by plasterboard, the joints has been smeered with what looked like filler and a painter was there in the process of painting this plasterboard

Could someone remind my aging memory of what would achieve 30 minute fire resistance?

My memory is that  that a 9.5 mm plasterboard had to  have a skim of plaster but a 12.5 mm plasterboard didn't...but as I said it's aging

cheers

Try British Gypsum website. I think your spec for plasterboard  FR is maybe from a bygone age but I could be wrong. Fireboard seems to be the thing. I do know of a BC Dept that would not accept plain skimmed plasterboard for fire protection purposes.

It was only a brief encounter with an ex-door/new wall, as I was visiting draculas assistant, but I'd imagine the door furniture went the same way as the door itself
