External White Colour Help and Colorbond Roof Colour

6 years ago

If we have decided on a white render, which Dulux white would you go with (thinking maybe Surfmist) and Ironstone or Basalt Roof ? Photos above are what we like. Our elevation below, will plan to do trims and cladding in Lexicon Quarter.

Solar absorption of Basalt is 0.69 with Monument at 0.73. Both are considered to be dark according to the BCA. So really not a significant difference at 0.04.....

To make a lot of difference you'd be looking at Shale Grey at 0.43 or Surfmist at 0.32.

Use a 75mm foil backed blanket as a minimum under roof sheet.
