Plasterboard thickness sizes

evosteo

Hi folks. Just looking for a bit of info. I know drylining comes in 9.5mm and 12.5mm standard sizes.

From searching on google theres also a sound board available which is 19mm thick

Is there any other thickness sizes that they come in apart from insulated plasterboard?

Like 15mm 17mm etc.....

Cheers

Steve

12.5mm is the most common but you can easily get 15mm and as you mentioned 9.5mm.

Bear in mind the extra weight as you move up from standard 12.5mm.

Why are you looking for thicker sizes than standard?

9mm for ceilings, typically 12.5mm for walls, although I've seen houses with 9mm used on walls.

dont do that. slabs are weak enough as it is without going for 9mm on walls. you damage it too easily. if you want to do that then put ply behind it

jack of all

Also be careful with what thickness you use on ceilings- 9mm is not suitable for use with prefab trusses at 600mm c/s as it will sag over time, use 12mm here. Only use 9mm on ceiling joists at max 400mm c/cs. Thicker plasterboard on stud partitions will improve acoustic performance.

I was working in my sisters house which is timber framed and in the middle of a terrace. We were stripping back the wall in the bathroom due to moisture damage from badly installed tiles. The 1st layer of plaster board was standard 12.5mm. Behind that was 15-17mm thick plasterboard im 600mm wide sheets. Never come across it before so i was shocked to see it. Spoke with the lads in the builders providers who said its not used as much anymore. Advised to double up 2 x 9.5mm slabs instead covered up by 12.5mm moisture board in the new shower enclosure. Job done. Cheers for the info lads

You sure the new build meets the fire regs in a terraced TF house for what may have been a load bearing wall?
