In the Romandy region of Switzerland, the amount for external thermal insulation largely depends on the chosen method. Several processes can improve the energy performance of a facade, each having its own characteristics in terms of finish and durability.
The most common technique remains insulation under plaster, but other systems can be considered depending on the configuration of the building.
For a house of about 100 m², the total budget can vary significantly depending on the chosen solution, the materials used, and the complexity of the project.
On average, in the Romandy region of Switzerland, the overall cost of a complete external thermal insulation (ITE) ranges between 13,300 CHF and 22,800 CHF, including installation.
| External insulation technique | Average price per m² (supply + installation) | Estimate for 100 m² |
| Insulating plaster | 85 to 133 CHF/m² | 8,550 to 13,300 CHF |
| Insulating panels under plaster (ETICS) | 114 to 190 CHF/m² | 11,400 to 19,000 CHF |
| Cladding | 133 to 257 CHF/m² | 13,300 to 25,650 CHF |
| Insulating covering | 152 to 209 CHF/m² | 15,200 to 20,900 CHF |
| Vacuum insulating panels (VIP) | 190 to 304 CHF/m² | 19,000 to 30,400 CHF |
Whether done under plaster or with cladding, external thermal insulation may require certain complementary interventions that add to the initial budget.
Here are the main items that may increase the overall cost of the project.
Before selecting an insulation solution, it may be relevant to conduct a complete thermal analysis of the home. This study helps identify areas of heat loss and guide the choice of the most effective insulators.
To obtain reliable results, it is recommended to consult a qualified specialist.
An air infiltration test detects air leaks in the home. This operation involves pressurizing the building to accurately measure air leaks.
In the Romandy region of Switzerland, the average cost of this analysis is around 620 CHF, depending on the configuration of the home.
During external insulation, certain additional interventions may be necessary.
For example:
These adjustments may affect the overall budget of the project.
