[quote=Anonymous][quote=Anonymous][quote=Anonymous]concrete walls have an r value of around .1 per inch, so basically a thermal conductive highway. [/quote] What are you talking about? You think that is the only calculation for efficiency? [/quote] "What am I talking about?" I'm talking about putting in a concrete wall for a single or two story house that has a wide profile for the wall assembly with almost no insulating value. So then you have to add significant width with a framed wall and insulation on the interior, or layers of XPS, EPS, or polyiso on the exterior. What is the point of that significant inefficient wall assembly with an enormous carbon footprint?[/quote]
