Plaster board touching dpm

[CB76]

Hi,
I am building a garden studio and wanted to know if it's okay for plasterboard to touch dpm or vapour barrier on single skin wall and if so should i use moisture resistant plasterboard. I have the dpm on a concrete slab which goes up two courses of breeze blocks (one course is under ground)to link in with the dpc. Timber frame is on top of breeze blocks. Vapour barrier will be between dpm and plasterboard.
Hope this makes sense. Thanks

from what i can make out you should be ok just keep the p/b about 50mm off the floor.

Hi Bobasd,
Thanks for that. Would it be advisable to use moisture resistant plasterboard or would standard be ok? Thinking of using 9.5mm to keep cost down.

 

[bobasd]

use regular 12.5mm p/b.

I would use poly backed plaster board...

Was planning on using foam sheets behind plasterboard but want to leave out now due to a number of reasons.
