Hi
I just was reading my building contract and in the Addendum said that Wall insulation note .. Not applicable .. is this mean that I don't have insulation in the walls???
According to the roofing section
I have Insulation R4.0 in Roof with Polyglass Batts
The builders said that the house could get easily 6 start rating because the orientation, but now I'm wondering about if it is ok without insulation in the walls.
Anyone have an idea of how much cost to put insulation in the cavity wall (it is double brick) and if it's really necessary for Perth metro area
If I really need it .. Could I upgrade in the pre-start or I have to change all the contract???
The house is going to be build in Perth Gosnells..
Thanks in advance!!
