$$R = \frac{e}{\lambda}$$

Where:

• $R$: Thermal Resistance ($m^2 \cdot K \cdot W^{-1}$)
• $e$: Thickness ($m$)
• $\lambda$: Conductivity ($W \cdot m^{-1} \cdot K^{-1}$)

So your insulation layer is wall_consol_layer:

You just have to calculate the R-value of materials:

$$R = \frac{e}{\lambda}$$

Where:

• $R$: Thermal Resistance ($m^2 \cdot K \cdot W^{-1}$)
• $e$: Thickness ($m$)
• $\lambda$: Conductivity ($W \cdot m^{-1} \cdot K^{-1}$)
