9.5 or 12.5 mm

[Terry7556]

Conservatory built, firm are about to plaster/dot & dab using 9.5mm p/bd
Why not 12.5mm
When I go to magnet 12.5 is cheaper than 9.5 so what's the benefit of using the thinner material

Tell them you want 12.5mm boards as they are stronger and less likely to get bashed and dented. Don't accept any "flannel" off them tell them you want 12.5 Boards....You will probably regret it if you dont

I agree with Roy,, use 12.5mm boards, far stronger. There's no benefit at all in using thinner boards.
