Our bedroom faces south and the outer skin of the upper storey is made up of dark stained horizontal wooden cladding apparently fixed to the inner block skin by battens, probably no more than 1" thick. There is no vapour barrier we can see and the temperature in the summer is beyond words! The process must be that the dark wood absorbs solar radiation and passes the stored heat to the block material, which then kindly radiates into the bedroom. We are told that to insert a layer of insulating material would require the entire cladding to be removed, insulation material to be placed between battens, a vapour barrier to be fixed over and then the cladding re-applied. I guess the other alternative would be to apply dry lining board with polystyrene layer to the inside walls. Anyone had experience like this? Any suggestions? Any idea how much of a temperature reduction could be achieved by either method?
We are in the south of England and our summers are becoming warmer and longer so this is a problem we need to address.
Thanks
