At Avenir Renovations Switzerland, we guide you towards the most suitable solution for your home, taking into account your energy goals, the technical constraints of the building, and the budget you wish to allocate to your project.
The chosen material directly influences the total cost of the work.
Here is an estimate of the average prices observed in Switzerland for an area of about 100 m², expressed in Swiss francs (CHF).
| Insulation | Average price for 100 m² (CHF) | Particularities |
| Expanded polystyrene | 1,140 to 2,280 CHF | Economical solution with good thermal performance |
| Extruded polystyrene | About 2,280 CHF | High resistance to moisture and excellent strength |
| Rock wool | 1,710 to 3,325 CHF | Good sound insulation, fire resistance, breathable material |
| Polyurethane | 1,710 to 2,850 CHF | Very high thermal performance with low thickness |
| Glass wool | 1,330 to 2,280 CHF | Lightweight and easy to install, reliable thermal efficiency |
| Wood fiber | 1,900 to 3,040 CHF | Eco-friendly insulation improving thermal and acoustic comfort |
| Cellulose wadding | About 1,900 CHF | Recycled material offering good durability |
Expanded polystyrene is both an economical and effective solution for exterior insulation in Switzerland. Due to its lightweight and insulating properties, it is frequently used in projects aimed at improving the thermal performance of a house while keeping the budget under control.
For a 100 m² home, the cost of the material generally ranges between 1,140 CHF and 2,280 CHF. To obtain a complete estimate including implementation, it is recommended to request a personalized quote.
Denser than expanded polystyrene, extruded polystyrene offers excellent resistance to moisture and mechanical stress. It is particularly suitable for facades exposed to the elements.
To insulate an area of approximately 100 m² in Switzerland, the cost of the material averages around about 2,280 CHF, depending on the chosen thickness.
Rock wool is valued for its versatility. It provides good thermal insulation and excellent acoustic performance. Fire-resistant and vapor-permeable, it also helps to limit moisture problems.
For a 100 m² house in Switzerland, the price of the material generally varies between 1,710 CHF and 3,325 CHF.
Polyurethane stands out for its particularly high insulating capacity, allowing for excellent results even with a reduced thickness.
To insulate a 100 m² house, the cost of the material generally ranges between 1,710 CHF and 2,850 CHF in Switzerland.
Glass wool is a lighter alternative to rock wool while offering comparable thermal performance. It is easy to handle and quick to install.
For an area of 100 m², the cost of the material generally ranges between 1,330 CHF and 2,280 CHF.
Wood fiber is a highly valued natural insulator in sustainable renovation projects. It enhances thermal and acoustic comfort while contributing to the regulation of indoor humidity.
For a 100 m² house in Switzerland, the price of the material generally ranges between 1,900 CHF and 3,040 CHF.
Cellulose wadding is made from recycled paper. It represents an ecological solution offering good thermal performance and great durability.
To insulate an area of 100 m², a budget of around 1,900 CHF is needed for the purchase of the material, excluding installation.
In Switzerland, the amount of 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 resistance.
The most common technique remains insulation under render, but other systems can be considered depending on the building's configuration.
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 Switzerland, the overall cost of a complete 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 render | 85 to 133 CHF/m² | 8,550 to 13,300 CHF |
| Insulating panels under render (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 facing | 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 render or with cladding, external thermal insulation may require certain additional interventions that add to the initial budget.
Here are the main items that can 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 efficient insulators.
To obtain reliable results, it is recommended to consult a qualified specialist.
An air infiltration test allows for the detection of air leaks in the home. This operation involves pressurizing the building to precisely measure air leaks.
In Switzerland, the average cost of this analysis is around 620 CHF, depending on the configuration of the home.
During external insulation, certain ancillary interventions may be necessary.
For example:
These adjustments can affect the overall budget of the project.

Carrying out external thermal insulation can represent a significant cost for homeowners. Fortunately, in Switzerland, several financial aids and incentive programs are offered to support energy renovation projects and reduce the overall budget for the work.
In several cantons, incentive programs allow for financing part of the insulation work.
These subsidies are generally granted when the work significantly improves the energy performance of the building.
Some schemes provide enhanced financial support for households with modest incomes. This facilitates access to energy renovation work.
Some financial institutions offer loans specifically designed to finance work aimed at improving the energy performance of a home.
These solutions allow for spreading the cost of the project while achieving long-term energy savings.
In some cases, energy improvement work may qualify for tax deductions. This helps reduce the final cost of the investment.
Whether it is insulation done from the inside or the outside, the quality of the result largely depends on the company chosen to carry out the work. By entrusting your project to Avenir Renovations Switzerland, you benefit from comprehensive support and the expertise of a network specialized in energy improvement projects for homes.
