Reply To: Underfloor insulation mandatory?

All great technical rationals added above.

Insulation for the under floor, most definitely, with out question, do it

In a simple view, my personal opinion is we focus in NZ on the “minimum requirement” way too much. This will clearly be the cheapest budget way to get council approval for your build but why focus on the minimum. A constant issue I faced when insulating new builds was “what will get me council sign off”. Clients would happily spend thousands on nice tap fittings etc, but want to scrimp on what can’t be seen behind the gib/under the floor. 1-2% of total build cost is all the insulation will cost and the improvement to total house performance is massive, virtually vital in my view.
