So battons over the 'final' pir - plasterboard fixing to that? Link to comment Share on other sites More sharing options...

Yes unless you do what we did and go with board between the battens. You’re talking about a cold bridge 50mm square at best that is made up of 200mm of timber - it’s got about the same loss overall as one of your windows so don’t panic ..! Much easier to get a flat finish too. This then has 100mm foil tape over it to form the VCL. 2 Link to comment Share on other sites More sharing options...
