I just googled & found this site, which quotes cost of R2.5 75mm. there are other suppliers as well. What was quoted to you for cost of roof installation, and was it itemised so you can see exactly what thickness the foil-backed insulation builder will use? I'm guessing the thinner (lower R factor). So, the new quote should reflect a credit for the cost of previous insulation, since it won't be used, then cost of thicker insulation added. Does that make sense? If you are unsure, best to speak with the builder. https://www.pricewiseinsulation.com.au/product/heavy-duty-fletcher-permastop/

I don't like drab except as a way of filling in the gaps . Oops , bloody autocorrect , I meant dune . And anything grey . I'd actually go Eucalypt on the walls and roof , 'natural' wood but with a charcoal or green tinge , and Forest Green for the gutters and barge boards around the roof , the windows and also that front veranda roof , just as a bit of contrast . Yes , I know , it will get a bit warmer , but it's 1/20th of the cladding , on 25% of the year , so live with it ! And of course , the nicest bright dark green shade you can get for the front door . Don't want greens ? Go with surfmist as the main , roof and walls , Deep Ocean everywhere I suggested Forest Green , and an almost glowing Royal Blue front door .

Hi I'm on Sydney Northern Beaches and we are about to renovate our house. I would like to clad it in matt colorbond. I've heard that this is a great finish, but that you need to insulate (a lot) or it gets very hot. I'm thinking Monument or Basalt as the colour. Has anyone used this recently.

Timber paling fences vary depending on whether it's hardwood or treated pine and whether the in-ground posts are timber or not. Ours were concrete but from time to time individual palings warped and came loose and needed to be hammered back down. The posts were still standing when we eventually decided to replace with colorbond. A fence replaced only a few years ago shouldn't be leaning if it was done properly?
