Hi, I am new to the forum and wonder if anyone is able to help me with some insulation queries. I am building a new home, 176 sqm house, garage 40sqm, alfresco under roof 22sqm. Concrete slab, colorbond roof. I live in southern Victoria. (Gippsland)
To attain 5 star, rater has included R5 ceiling batts. I am keen to use loose fill insulation in the ceiling to fill all and any spaces however various suppliers rate this as only R3 or thereabouts. What else could I do to achieve R5 in the ceiling rather and use loose fill as compared to the insulco R5 batts.?
Also querying how many packs of batts I would need for the ceiling if I end up having to use the insulco R5 product.
Last question, should I ceiling insulate the garage and alfresco too, or just the living areas?
All advice appreciated
