We have a cathedral raked ceiling in our lounge, kitchen, family room area. We have only a small amount of space between the colourbond roof and the battens where the plasterboard will go. There is a 50mm anticon blanket already installed.
My question... I know foil is better for heat insulation, but I dont think it will give any acoustic insulation and we have a colourbond roof.
We live in SE Qld....and we are thinking of putting battens in so that we get some acoustic properties...
any comments???
