Hello,
Is it recommended to include a vapour barrier to protect the insulation & timbers during renovation? Alternatively, will it do any harm to put up 1000 gauge polythene before plasterboarding?
Bay is in the front living room. Roof is insulated using 50mm cavity wall boards between the joists - Xtratherm Thin-R CW cavity wall boards if it's worth mentioning (similar to Celotex), plus 100mm std insulation blanket above that.
Cheers..
