yes, since masonry has so little resistance to heatflow, about r0.2 per
inch, eg 100" for an r20 wall. this site is confused, with statements like
"...the low specific heat of thastyron results in a wall surface close to
ambient room temperature," and specs like a "dynamic r-value of 22.6" for
a 10" wall in minneapolis, vs a static value of r11. it cites "sickness due
to tightly laid reinforcing forming a faraday cage" as a disadvantage of
conventional concrete. woowooowoooo... very green architecture.
