Improving the energy efficiency of a home often involves treating vertical surfaces. In the French-speaking part of Switzerland, poorly insulated walls can account for up to 20% of thermal losses in a home.
When external insulation is not considered, interior insulation is a relevant solution. It improves thermal comfort and helps reduce heating consumption.
The average price for insulating walls from the inside ranges between 47 CHF and 90 CHF per m² including installation. For materials alone, the budget typically varies between 21 CHF and 42 CHF per m², depending on the chosen insulation and its thickness.
Attics are a key area for energy efficiency since heat naturally tends to rise.
In converted attics, insulation is generally installed under the framework in the form of panels or rolls fixed between structural elements.
In uninhabitable attics, the technique of blowing in loose insulation is frequently used. This method allows for a homogeneous layer covering the entire surface.
In the French-speaking part of Switzerland, the cost of interior attic insulation averages 42 CHF to 80 CHF per m² including installation. The materials alone account for approximately 16 CHF to 32 CHF per m².
The roof is one of the main areas of thermal loss in a house. Effective insulation is therefore essential to improve the overall performance of the building.
In homes with a sloped roof, insulation is generally installed between the rafters from the inside.
Before any intervention, it is important to check the condition of the framework. The presence of moisture or damage may require preparatory work.
The average cost to insulate a roof from the inside ranges between 63 CHF and 125 CHF per m² including installation. Excluding labor, the price typically varies between 32 CHF and 58 CHF per m².
Poorly insulated floors can cause a feeling of cold and lead to significant energy losses.
In houses built on crawl spaces, the installation of synthetic insulating panels is often preferred. In some cases, natural materials may also be considered.
In the French-speaking part of Switzerland, the cost of interior floor insulation ranges between 52 CHF and 100 CHF per m² including installation. For materials alone, the budget is between 26 CHF and 47 CHF per m².
Basements and underground spaces are particularly exposed to moisture due to their direct contact with the ground.
Before implementing the insulation, a waterproofing treatment may be necessary to protect the walls.
The cost to insulate a basement from the inside in the French-speaking part of Switzerland generally varies between 68 CHF and 147 CHF per m² including installation. Without labor, the budget ranges between 37 CHF and 95 CHF per m².
