Hi,
I am trying to work out the resistances for the following cavity wall. I am having to work backwards. I have the U value, which is 0.48. The brickwork is 103mm, the insulation in cavity is 50mm, lightweight concrete block is 100mm and plaster board is 13mm.
I know
total thickness (0.103+ 0.050 +.100+.013) / total resistance = a
1/a = .048.
Thanks
