Can anyone help me in deciding the insulation in my new double storey west facing house.The builder is offering the following as standard:
- Minimum R1.5 Batts to external walls with foil wrap.
- Minimum R3.5 Batts to ceiling( I got colorbond roof with sarking and one whirling bird)
Apart from this I have already added R1.5 Batts to all internal walls.Do you guys think that is enough for the Melbourne cold weather and hot summer?
When i asked for the upgrade they said they can do the following(with extra cost ofcourse!)
- R 2.5 batts to external walls ( cost approx $1000)
- R6.0 to ceiling ($500 approx)
Is it worth going for them?Because they have already put a buffer in quote to make it 6 start rated.
Any suggestions will be highly appreciated.Thanks
P.S Our builder is Henley.
