Properties of the exterior rendering (resin finishing coat).
| Property | Adopted value |
| Basic properties | | Bulk density (kg/m³) | 1600 | Porosity (m³/m³) | 0.2 | Heat capacity (J/kg·K) | 850 | Heat conductivity dry (W/m·K) | 1 | Diffusion resistance factor dry (—) | 25 | Additional hygrothermal functions | | Moisture storage function | No* | Liquid transport coefficients for suction and redistribution (m2/s) | 0 | Water vapour diffusion resistance factor, moisture-dependent | Not moisture-dependent | Thermal conductivity, moisture-dependent | Not moisture-dependent |
