top I know I saw the info around somewhere, but I’ll be damned if I can find it. The only thing I can find, if its any use, is this section from the Bulletin 5 “Earth Wall Construction” by the CSIRO (Commonwealth & Scientific Research Organisation) Division of Building Construction and Engineering. It says: 3.6.1 Insulation: The insulation properties of earth-wall are similar to those of concrete or brickwork. Actual values are given in the table below. Good insulation results from the greater thickness of the wall. Thickness (mm) U-value W/M(squared) (degrees)C 250 2.86 300 2.56 350 2.33 400 2.14 450 1.97 Latest info on R ratings: And it isn’t encouraging… The CSIRO has done a study which shows that the insulation properties of Rammed Earth is pretty low.
