Insulated plasterboard - walls not level.

[Tommy19]

Hi guys,

Hoping someone can offer advice on this.

I am wanting to apply insulated plasterboard to my external facing solid walls. I understand the foam is the chosen option however when putting a level on my wall I can see the top part of the wall is 30-40mm out.

What would the best method be here? Battens with packers? I’m assuming that’s too much of a gap for the foam? Thankfully it’s just this one wall and which is this bad.

Thanks
Tom

Bodging time! Maybe foam some plasterboard over the deep areas to bulk them out.

Have you checked your spirit level…….

Ha, yep I have checked it!

What about batten packed out with shims / wooden wedges?

Batten with shims/wedges will work fine and gives you a useful 'hard' line to level to. Drywall adhesive (the stuff used for dot and dab) will also work at that thickness but it gets expensive...
