Hi,
We will be building a new house in north west sydney area and just working what insulation we ask the builder to include. Any advice on what is worth spending the extra money on would be appreciated.
The house will be hebel panels, and roof will have sarking.
Builder does R3 in ceiling, so we want to increase that to R4. And also insulate garage ceiling.
In the walls R2 is standard. Not sure if it's worth increasing to R2.5? (Sales said R2 is max that fits in external wall, but I want to ask again)
Should we leave it as R2 in external walls and then get wall wrap (instead of increasing to R2.5)
The more insulation the better, but with a limited budget just trying to work out where our money is best used.
Thanks!
