Hi
We are building the Cremorne 41 with PD and the standard insulation provided as part of the 5 star rating are:
R1.5 GlassWool Batts to the wall and
R2.5 Cellulose Fibre insulation to Ceiling.
Any idea is this good enough or should we upgrade ? If upgrading, any idea to what and how much it would cost (especially those who are building with PD).
Thank you
