We want our build to be as thermally efficient as possible, and have been told that a roof blanket isn't necessary, and that PD can only install wrap and sisal in the walls...
A couple of my custom builder mates won't install a colorbond without without a blanket, and nearly always install bats to exterior walls..
Our sales consultant is being awesome trying to get a win for us, but ultimately, if we're prepared to pay for it, what's the issue?
This would make our build closer to 7 star than 6... Surely that's a win for PD too?
Sarking is an additional cost that PD does not include in the base price. We added it on no issue.
As for the insulation, wait for your energy rating application. Most likely they will ask for upgraded insulation and PD will upgrade those at no cost to you. Then you can choose wether to upgrade even further from what they will include as a minimum for 5 or 6 star rating.
Hope that helps.
How much do PD charge for sarking now?
