ECO block is the name used for the ones my helper installed. Foam insulation on outside and inside acting as a form, reinforced throughout, and poured concrete on the inside. Very good for veneer if set up with the shelf. Wish I had went this way on my cabin instead of block. The price was more but I believe would have been money well spent.
If these are all the same thing with different names, I do not know. Good advise from Jim R. on contacting the manufacturere.
