Why carry out insulation work in the Swiss Romandy
Insulation is not just a simple technical improvement. It is an investment that directly impacts the quality of life, real estate value, and energy performance of your property.
Reduction of heat loss
Effective insulation prevents heat from escaping, thus reducing heating consumption. This helps maintain a pleasant temperature in winter while limiting thermal variations indoors.
Thermal comfort in all seasons
Good insulation protects against winter cold and preserves coolness in summer. It stabilizes indoor temperature, thereby improving the well-being of occupants regardless of the time of year.
Real estate enhancement
A well-insulated home is more attractive on the real estate market. Future buyers pay attention to energy performance, and recent insulation can justify a better valuation of your property.
Reduction of environmental footprint
By consuming less energy to heat or cool your home, you contribute to the reduction of CO₂ emissions. Insulation is therefore one of the key actions for a more sustainable dwelling.
Steps of an insulation project with Avenir Rénovations Suisse
Each insulation project is carried out according to a precise process to ensure an optimal, durable result that complies with local regulations.
The different types of insulation work
Depending on the configuration of your home and your goals, several insulation techniques are possible. Avenir Rénovations Switzerland advises you to choose the one best suited to your project.
Roof insulation is essential as it is where most of the heat escapes. It can be done from the inside or the outside, depending on the structure of the building.
This technique involves placing insulation on the internal walls. It is ideal for renovating without touching the facade while improving the thermal and acoustic comfort of the home.
External insulation wraps the building in a protective layer. It improves thermal performance and renovates the aesthetic appearance of the facade at the same time.
By insulating floors located above basements, garages, or crawl spaces, heat loss through the floor is limited. This is an effective intervention to improve the overall comfort of the home.
In addition to thermal insulation, it is possible to install materials that reduce noise disturbances. This allows for a quieter and more pleasant environment on a daily basis.
How much do insulation works cost in the Romandy region
The cost of insulation depends on the type of intervention, the materials chosen, the area to be treated, and the complexity of the site. Prices may vary depending on location and access constraints.
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Insulation of lost attics | 60 to 90 | 3,000 to 4,500 |
| Roof insulation from the outside | 180 to 250 | 12,000 to 18,000 |
| Wall insulation from the inside | 100 to 140 | 6,000 to 9,000 |
| Wall insulation from the outside | 180 to 250 | 18,000 to 25,000 |
| Insulation of ground floors | 90 to 130 | 4,500 to 6,500 |
These prices include technical study, supply of materials, labor, finishes, and warranty. A precise quote remains essential to assess the exact cost of your project.
Insulating materials for your work
The choice of materials is crucial for the performance and durability of insulation. Avenir Rénovations Switzerland selects certified products that meet Swiss standards.
Mineral wool
Glass wool and rock wool offer excellent thermal and acoustic performance. Fire-resistant, they adapt to many types of work and interior configurations.
Natural insulators
Hemp, cellulose wadding, and wood fiber are ecological alternatives. Derived from renewable resources, they provide good summer comfort and limit environmental impact.
Synthetic insulators
Polystyrene and polyurethane guarantee high thermal performance with low thickness. They are well-suited for challenging areas such as facades or roofs.
Financial aids for your insulation work in the Swiss Romandy
In Switzerland, insulation is encouraged by various financial aid programs aimed at reducing the energy consumption of buildings and CO₂ emissions.
Cantonal and municipal subsidies
As part of the Building Program, several Romandy cantons grant subsidies for high-performance insulation work. The amounts vary depending on the materials, the performance achieved, and the insulated area.
Energy bonus
Some energy suppliers offer bonuses to encourage energy renovations. These aids can be added to cantonal subsidies and represent an additional financial advantage.
Reduced VAT rate
For energy improvement work, a reduced VAT rate may be applied, thus lowering the overall cost of the operation.
Eligibility conditions
To benefit from these aids, it is imperative that the work is carried out by a qualified professional and that the chosen materials comply with Swiss thermal standards, notably the SIA 380/1 standard.
Regulations for insulation work in French-speaking Switzerland
The insulation of a building is governed by strict regulations to ensure energy performance and architectural compliance.
Permits and preliminary procedures
In some cases, a municipal permit is required, especially for external insulation that alters the appearance of the façade. Deadlines and formalities vary by canton.
Thermal standards
The work must comply with the SIA 380/1 standard, which sets minimum requirements for energy performance. These values ensure a significant reduction in heat loss.
Work in co-ownership
In a co-ownership, any intervention on common areas such as the façade or roof requires the agreement of the co-ownership. A permit at the general assembly is generally required before starting work.
Compliance with safety rules
Interventions, especially at height, must comply with strict safety standards. Careful installation ensures airtightness and avoids thermal bridges for durable and effective insulation.
FAQ on insulation work in French-speaking Switzerland
Is a permit required for external insulation?
Yes, most municipalities require a permit or authorization for any façade modification. This allows for verification of the aesthetic and energy compliance of the project.
What is the return on investment for insulation?
On average, good insulation can reduce energy consumption by up to 30%. The return on investment can range from 5 to 10 years depending on the initial cost and the savings generated.
Insulating an old house without changing its appearance
It is possible to insulate an old house from the inside to preserve its façade. Suitable solutions exist, even for listed or protected heritage buildings.
Most effective insulating materials
Mineral wools are economical and effective, while bio-based insulators offer better comfort in summer. The choice depends on your priorities: thermal performance, sound insulation, or ecological impact.
Insulation and acoustic improvement
Some insulating materials, such as rock wool or wood fiber, also reduce external noise. This significantly increases sound comfort inside the home.
Assistance for partial insulation
Subsidies are possible even for partial insulation if performance standards are met. However, the intervention must be carried out by a certified professional according to cantonal requirements.
