Why install a roof window or a Velux in French-speaking Switzerland
Installing a roof window or a Velux is not just an aesthetic choice; it is also an investment that affects daily comfort, energy efficiency, and the value of your property.
Improvement of natural light
A well-positioned roof window significantly increases the amount of light in a room, sometimes up to twice as much as a vertical window. This natural light promotes well-being and gives a sense of a larger and warmer space.
Optimization of ventilation and air quality
In addition to letting in light, a roof window facilitates air circulation. Regular ventilation improves indoor air quality, reduces humidity, and prevents mold formation, especially in attic rooms.
Property enhancement and aesthetics
A room in the attic with a well-integrated Velux gains appeal and value in the real estate market. The modern and neat appearance of these openings contributes to the architectural harmony of the house and its high-end image.

Regulations for the installation of roof windows and Velux in French-speaking Switzerland
In Switzerland, the installation of a roof window or Velux is subject to certain rules to ensure safety, compliance with urban planning, and energy conformity. Depending on the canton and municipality, requirements may vary, so it is important to gather information before starting work.
Permits and preliminary steps
In most cantons, any visible modification to the roof, such as the installation of a Velux, requires a municipal permit or a simplified building permit. This step allows for checking the aesthetic and architectural compliance of the addition with the building and its environment. Deadlines and formalities vary from one municipality to another, but it is advisable to anticipate this request to avoid delaying the project.
Thermal standards and legal requirements
Roof windows must meet the insulation standards defined by the SIA 380/1 standard, which sets maximum values for the thermal transmission coefficient (U). This ensures that the installation contributes to the overall energy performance of the building and qualifies for certain financial aid. Certified products generally offer better thermal comfort and reduce heat loss.
Work in co-ownership or PPE
If your housing is in co-ownership or in a property by floors (PPE), you must obtain the agreement of the other co-owners before any external modification. Internal regulations may impose certain restrictions on the size, shape, or color of the roof window.
Compliance with safety and watertightness rules
The installation must be carried out to ensure perfect airtightness to air and water, in accordance with the manufacturers' specifications and current standards. Appropriate safety measures must be implemented during the work to protect occupants and workers.
Take advantage of financial assistance for the installation of roof windows and Velux
The installation of a Velux or a high energy performance roof window may qualify for subsidies and financial incentives, depending on your canton or municipality. These aids aim to encourage energy renovation and reduce energy consumption in buildings.
Cantonal and municipal subsidies
As part of the Buildings Program, several cantons in French-speaking Switzerland offer subsidies for the installation of high thermal insulation windows. The amounts vary depending on the type of glazing and the performance achieved, but can represent significant financial support.
Reduced VAT rate
For work aimed at improving the energy efficiency of a home, the reduced VAT rate may apply. This lowers the total cost of the investment and makes the project more accessible.
Energy bonus and specific credits
Some municipalities and energy suppliers offer bonuses to encourage the use of high-performance windows. These aids are generally cumulative with cantonal subsidies, increasing the financial interest of the project.
Eligibility conditions
To benefit from these aids, it is essential that the installation is carried out by a certified professional and that the chosen windows meet the energy performance criteria set by the authorities. Avenir Rénovations Suisse assists you in preparing the application and finding available funding.
