|+ align="top" | R-values per inch given in SI and imperial units. In practice, the values for the materials will have been obtained using different methods. Typical values are approximations based on the average of available figures. Clicking on the RSI column sorts by median value of the range. Clicking on the R-value column sorts by lowest value.
