Does anyone have any pink plasterboard that they feel like recording and setting on fire? I've not managed to find a video. Lots of speculation and thoughts but no actual footage.

Just interested to see how it actually does burn when hit with heat and also a flame.

Anyone care to indulge me?

Thanks

Pink should be fire and possibly moisture resistant.

It’s one of the least combustible materials you’ll find. When tested to BS476 which tests it to some pretty unfavourable conditions it achieves A2-s1,d0 which basically means it doesn’t burn, doesn’t smoke and doesn’t drip when exposed to a sustained flame.

I used to build test pieces for BS476 tests and it's somewhat unnerving how you can be throwing 1000 degrees at it via what looks like a fighter jet with the afterburners on and it just sort of does.... nothing biggrin

Never thought about it but I can't imagine normal plasterboard is particularly flammable, barring the paper. Is this actually the case?

Thank you.

So what happens to the paper layer on pink board? Will it catch, or not.

Does the board (the actual structural plaster part) eventually crumble?

Thanks

Burn test video here, unfortunately it's from the Americans. In essence everything burns eventually, pink plasterboard just gives you a tested resistance to fire for long enough to evacuate the building.

Its reasonable fire retardant, but as anyone whos made a mess of cutting it know, plasterboard without the paper is very fragile.
