Thankyou for your answer regarding our drywall concerns. You advised 2×4 and 6mm poly but didnt mention insulation.Should we use pink insulation?,styrofoam,or no insultaion.
We live in a northern climate.Thank you
Fiberglass would probably be fine. You should also check your local building codes for this. Blown in foam would be good also, but is about twice the price.
