Hi,
we just recieved our preliminary estimate for our house but have been given a bit of a shock regarding energy rating costs.
On our house we have 3 large sliding doors on the rear of the house, 2 will be facing a little bit north of straight west and the 3rd facing north. This brought the cost up another $4k.
The builder had already quoted us double glazing everywhere else on the house except those doors and it has R6 ceiling, R4 in subfloor and R2.5 walls. Also we are on the eastern slope of a hill so the west sun should drop behind our neighbours pretty early.
Anyone aware of any other options for these doors we could bring up with the builder to get our 6 star?
