For example, to those R-values I would add the value of air spaces in the construction but I would deduct for those same air spaces if they are not sealed and protected from in-wall-cavity convection currents that can actually pump heat between the hot and cold side of such a wall. When buying various insulation materials you will almost always see an "R" value quoted for the material. The R-value of an unfilled 8-inch by 8-inch by 16-inch CMU is 1.11.
