We are looking into Gold batts for our ceiling and walls. We just want to know what we are talking about before we speak to builders.
If we use wall batts (90mm R2), do you still need foil wall wrap?
If we use Anticon 55mm with the foil backing, do we still need sarking, or is this what the foil is?
What components go into the walls? Foil wrap, and optional batts?
What would you recommend? Any information or links would help a lot.
