I have seen your recommendation for the Legalett concrete slab technology, but I wonder how their wall-insulation system compares to the wall systems that you propose. I see a number of advantages to their system--it's much less labor intensive and is potentially much faster to install. Also, one would only need to use 2x4 instead of 2x6. But the fact that you did not mention it makes me wonder. Kindly let me know.
