Thank you Guyod That's what I wanted to find out. Getting a little more insulation on the corners of the house is about all the benefit of not using 2 x4s and 2 x 6s as far as I can tell. I will go with the contractor that is using the 2 x4s and 2 x 6s.

My questions are: is the brittleness of cinder block going to causes screws to eventually detach, or is the glue alone weak enough to eventually detach? If screws coming out cause the block to fragment, it that repairable? How much weight can a furring strip hold? Is a 2 x 4 better for...
