Never come across this situation before but someone has asked me build a simple bungalow - 300mm cav construction - therms inside and high strength therms on the external skin.
The back wall will be then faced with a stonework face.
Thermalite have told him he can't use the high strength block for this application (ie; as a backing block).
He's asked me to build the rear elevation out of concrete blocks instead but still keeping the flank walls as thermalite - how would I build the corner? It doesn't seem right to me to come around a corner in thermalite & concrete blocks, i'm guessing they will move at very different rates causing cracking.....
Any thoughts anyone?
