Is there a type of plasterboard on the market that is both "moisture resistant and is insulating"?

I'm plastering a solid brick exterior wall which is in the kitchen and have been advised that "moisture resistant" plasterboard is sufficient but other people have mentioned "insulation" and so wondered if it's possible to get a type of product which has both of these qualities combined?

Edit: I should have mentioned that it's an Edwardian house and the wall has no cavity in it so it's a solid wall that's been taken back to brick. This is the reason that I've been advised to use moisture resistant plasterboard as well as some type of thermal insulation.

Generally you would affix solid insulation to the wall before the plasterboard.

We have never put moisture resistant plasterboard in a kitchen.  What are you going to be doing in there?  I'd save your money.

Agree with @Doozergirl ... can't see any reason for moisture resiatant in a kitchen.

You planning on putting up wall units on this exterior wall ?

If so, insulate and use plywood instead of plasterboard - Look up "warm batten" for ideas on how to do it.

Thanks for the reply Grenage.

Thanks grumber. That's an interesting product and it might be the most suitable.

Thanks for taking the time to reply Doozergirl. I should have mentioned that the house is Edwardian and so the wall is an exterior solid brick wall with no gap and am wanting to know if it's possible to use a plasterboard product instead of having to use a traditional lime coating.

I will want to put cabinets along some of the wall as well. Do you have any suggestions as to a satisfactory way. I know that it's suggested that a traditional lime plaster is applied but am wanting to know if plasterboard is suitable - Thanks

Thanks Bradden. Have you ever known situations where exterior walls without a gap have had moisture proof plasterboard added instead of lime plaster?

Thanks for your reply FreeBear. Part of the wall will most likely have units attached. I should have mentioned originally that the house is Edwardian and the wall is solid without a gap. I'm aware that a traditional method would be to use lime plaster but is it acceptable to use a plasterboard product and skim? All plasterers suggest that they've only ever used insulated plasterboard.

I will use plasterboard in an older house if I am totally satisfied that the wall is not a damp risk - so internal walls, upstairs walls and insulated plasterboard to some external walls if there aren't risks outside and the floor is well raised from ground level, for example. 

If the wall could be a damp risk then you can use metal studwork as batons (better than wood for obvious reasons)  fill with natural insulation and then board over with a natural board and then lime, or maybe plasterboard.  

Moisture proof plasterboard is the exact opposite of using lime - it's hiding damp instead of allowing a wall to breathe.  It's like sticking your fingers in your ears and singing 'lalalala' in terms of how it deals with damp.

So the exterior kitchen wall doesn't have a damp problem so therefore you mean I can use ordinary plasterboard perhaps with some insulation properties?

Moisture proof plasterboard has no point then being used on the inside of an exterior wall with no gap? I understand the logic regarding it preventing moisture to escape.

Always with insulation!  It's a no brainer to put insulation on if the plaster is off.  

If you have some damp issues, you want to know about it so you can sort it, not hide it.  Moisture resistant plasterboard is for bathrooms, nowhere else, imo.

Thanks for your reply Doozergirl. The guy who has bought the house from me "uncomplete" is going to insulate all of the walls. I didn't realize people did this in these older Edwardian mid terraced properties. Is this something you do when you refurbish houses can I ask?

I got the fundamental building works finished and decided to accept an offer from a chap who is going to change rooms around and use an architect and do further building works than I was intending to do.
