I have been looking into how to do this and have been finding mixed information. Can anyone give a clear answer, please?
We have solid outside walls which are rendered. The rendering is in good condition as it was re-done last year and there is no damp. The internal plaster is sound.
We wish to put insulated plasterboard on the outside wall where the staircase is, so space is a premium. My initial thoughts were to use adhesive to dot and dab the boards directly to the wall. However, some articles say that this method can result in damp patches and mould on solid walls because the glue creates a cold spot. Instead, they say to use battens.
So which is the correct method for a solid wall? Dot and dab directly to the wall or put in thin battens (1"?) and glue to the battens?
I should be grateful for advice.
Regards,
James.
