Maybe the weather has cooled a bit still ok here till we get the storm.... and the temp drops a fair bit.
I know NZ homes don't have a good reputation with insulation. Our house is maybe 40yrs old and the front of the house (lounge) has a high pointy roof with no accessible cavity. So insulation isn't even possible. Are these still allowed in NZ new builds? Like this image:
What about flat concrete floor where no underfloor insulation is possible.
For those of you who have ripped down gib and redid them what was the cost of doing so for a 3 or 4 bedroom typical NZ home? I know this isn't the requirement for existing homes and even rentals for that matter wall insulation isn't needed. There are new suburbs and streets with newer homes where they are more insulated per the building code but there are existing older suburbs like Mt Victoria in Wellington where many houses are over 100yrs old - you know some are inches away from the next door neighbour ;), some are yellow stickered (earthquake) but others are still OK. Thing is the land value there is quite high but the building itself might only be worth $100k, to some owners retrofitting insulation and double glazing windows might not be that beneficial right?
