Where to position insulation for plasterboard in loft
Posted: Mon Jan 23, 2023 1:09 pm
I want to put plasterboard walls in my attic but they will be about 40 cm in from the external walls. Should I put the glass wool insulation against the wall and have a gap between the insulation and the plasterboard or should the insulation be against the plasterboard and have a gap between the insulation and the external wall?
