What is the R-value for timber cladding?

The R-value for 19mm hardwood timber cladding is R 0.12.

ATFA states that the thermal conductivity of kiln-dried hardwood (across the grain) is 0.16 W/mK. The R-value of a material is determined by dividing the thickness (in metres) by the thermal conductivity of the material so the R-value of 19mm thick kiln-dried hardwood is R 0.12. R = Thickness (m) / Conductivity (W/mK) =0.019 / 0.16 = 0.12 (m²·K/W).
