I’m closing up an opening in my kitchen. I plan to do this with a studwork wall. Are there any regulations which cover the construction of the wall because it’s in a kitchen, i.e type/thickness of plasterboard used, number of layers of plasterboard, lagging to use in the cavity? If not, any recommendations?

Current plan is for the new wall to have a hatch in it (not over the cooked) - does that change anything?

Also, this wall will be finishing flush with the existing wall, how far recessed should the surface of the plasterboard be to allow a sensible depth of plaster (I shall have the whole wall skimmed - the existing wall won’t need any more than that).

A cooker and hood will back onto part of this wall – does that affect the construction?

Thanks

nivagg,
Use acoustic insulation in the wall pockets and face with 12.5mm plasterboard.
The junction between your masonry and stud wall will be a problem - consider overboarding into a corner.

Thanks for the quick response Stoneyboy. What is the nature of the problem with the interface between the two - is it that it will be difficult getting a snug fit, or is there a risk of the plaster cracking at the join due to different thermal expansions of the different materials?

Thanks

nivagg,
You will always get a crack along the line of the join.
