I am building a large outhouse at the back of my garden. 7m x 5m. It will have a flat roof and only be single storey. I want to use cellular clinker,breezeblock to build the outside (because it is lighter to work with, I am getting old and the dense concrete block is to heavy)and use thermalite block inside.
My local builders merchant tells me this block is only for oartition walls and is non load bearing and should not be used for this. The only load would be a flat roof. Surely I can use this block and render the outside.
Thanks Ian.
