R4.1 batt insulation to ceiling and R2.5 wall batt to external walls in included as standard in the house. We will be building our house in west Melbourne. Wondering if this is enough to provide comfort? i am more concerned about thermal insulation and not acoustic.
there is an option to upgrade to R2.0 batts to internal plaster stud walls. But not sure how much difference it will make.
probably a silly question - if we upgrade the R2.0 internal plaster stud wall, will my house turn into a sauna during summer?
appreciate your help..
