Can anyone help - we have the following inclusions for our skillion roof and are abit confused re R values and Anticon.
Colourbond (will be skillion surfmist or shale grey)
Anticon blanket
R3 roof insulation.
We're trying to figure out if the Anticon is counted towards insulation so we will have blanket +R3 batts. We figure our roof is a good place to work in thermal efficiency so looking for advice if this is a good level of insulation or should we upgrade blanket or batts to higher R values.
We're located in the Illawarra NSW and will have raked ceilings if that adds any considerations.
