Insulation values are most commonly expressed as R-values, a measurement that denotes the ability of a material to resist the flow of heat. R-values for residential wall systems typically range between R-12 and R-20, depending on climatic conditions, building code regulations, and type of insulation. Plastered bale walls have R-values ranging from R-30 to R-50, depending on their width and orientation.
