Was wondering if anyone can help me. Pretty easy one - I'm about to start plasterboard lining my loft, however, I was advised by an architect to use insulated plasterboard on the internal cheeks of the dormer.
I've been checking the insulated gyproc out and it's quite pricey - however, I do have a quantity of 75mm kingspan left. I'm just wondering if it'd be possible to use that with plasterboard on top as opposed to buying the thermaline stuff? On the other hand, 75mm might be a little thick, what would typically be recommended for a dormer?
