Drylining/stud wall questions

[naffoff]

Hello,

I'm installing some 50mm insulation board as part of some renovations that. Had looked at the laminated plasterboard, but need space for socket backboxes/cables etc. without compromising the insulation and vapour barrier.

I'll need to dry-line this, and also hang a 450x1400mm radiator on the wall.
Not sure of the radiator weight - I think it's probably > 50kg (bog standard Stelrad).

Am I best off using 2x4 timber and essentially building a stud wall, or will smaller battens do?
Or is there a better way of fixing the radiator brackets straight through to the stone, bearing in mind the sheer forces on long bolts?

Cheers,

Andy

Your choice of stud thickness will really depend on how much insulation you want between them - ie whether you want to maintain a minimum thickness of insulation, or if you can accept slightly reduced insulation where your electrical fixtures are

For the radiator, you can either locate vertical studs or horizontal noggins where the brackets will be, or recess some plyboard into the frame and this will give you more leeway for fitting the radiator

2x2 battens will do if you want to/can use them

Thanks Woody.

It's going to be 50mm behind the studs to avoid any thermal bridging (so it's continuous across the wall) - also, BC are inspecting for part L. May well insulate insulate between them, too, though.

Cheers
