| Frame profile | Timber exterior insulation finishing system (EIFS) | insulated PVC profile |
| Frame U-Value Uf [W/(m²K)] | 0.62 | 0.69 |
| Elevation width [mm] | 131 | 120 |
| Edge bond ψg [W/(mK)] | 0.031 | 0.029 |
| Glas rebate d [mm] | 26 | 30 |
| Glazing (44 mm) Ug [W/(m²K)] | 0.70 | 0.70 |
Example 2: External wall connection to unheated cellar ceiling
U-Value (External wall) = 0.12 W/(m²K) Thermal bridge coefficient: |
