Been in our 18 year old house since 2014 since returning from 30 years in Sydney and this is the coldest the house has been. This year been running the two heat-pumps more than previous years. Yes we do not have double glazing but do have floor length thermal lined curtains.
Needing to redo my 18 year old loose fill macerated paper ceiling insulation which has compacted down, there was properly never much to begin with, it certainly never covered the joists. There seems to be only an inch thickness. Tauranga has a R2.9 rating and this wouldn't make R1.0, plus over the included garage open ceiling space there is none.
So I am looking at loose fill R3.2 GreenWool-100%NZ.
Would be interested in members thoughts and local installer recommendations.
Will also be replacing all my vented light fittings with sealed LED's at the same time with Robus Taylor LED Downlight 10w, 3000k dimmable. Which I can pick up for $28ea.
