Hi guys,
Just wondering if anyone can advise if there is any tangible difference energy-wise between Colourbond roofing with Monument or Woodland Grey.
We are building in adelaide and prefer Monument, but not if its going to deliver a significant increase in cooling costs for the life of the house.
As an aside, would adding a whurly (sp.) bird to get the hot air out of the roof space help balance things out?
Our ceiling will have R3.0 and has a 25degree roof pitch with evaporative cooling, if it helps.
