Folks,
I want to build a house in Florida using surface bonded concrete blocks.
I like standard CMUs since these can be dry stacked (mortarless) but then it will be necessary to insulate the exterior walls outside.
If I use autoclaved airated concrete (AAC) blocks then the wall itself will provide the insulation but I have to use mortar. With AAC I do not need surface bonding, I need only ordinary stucco.
But I like the idea of surface bonding cement since it increases the wall strength and seals against water. Can this be applied to AAC blocks and how much more expensive is this than ordinary stucco.
Would it be cheaper to go with fully grouted ordinary dry stacked CMUs and ouside insulation on the exterior walls. What sort of insulations are recommended here?
Thanks
