I've just had the colourbond roof put on, and there was a roll and several metres of roofing blanket left over, and was wondering if it could be used between the bricks and frame as an additional insulation for the house ?
I'm going to be putting normal batts in the walls on the northern side of the house, and thought since this roofing blanket was R1.3 it could be of additional benefit over the R2.0 batts that were going to go in the frame behind the gyprock.
Are there any issues using roofing blanket in the walls, as the blanket has foil on one side ?
