Why insulate a building from the inside?

Insulating a building is an essential step in ensuring optimum comfort while saving energy. By efficiently insulating from the inside, you can significantly reduce heat exchange between the building interior and the outside environment. As a result, the need for heating in winter and cooling in summer is significantly reduced.
For example, well-insulated interiors can reduce heating energy consumption by up to 50%. Thanks to its innovative techniques, Bertolit offers extremely fine interior insulation, guaranteeing optimum performance without compromising living space. By investing in quality insulation, you’re also helping to reduce greenhouse gas emissions, playing an active role in the fight against global warming. Don’t wait any longer, contact Bertolit to transform your home into an eco-responsible and comfortable space all year round.

The different types of interior insulation

Interior insulation is a solution for improving a building’s energy performance while preserving its interior aesthetics. It involves wrapping the interior walls in a layer of insulation, protected by a finishing coat. The advantage of this method is that it effectively treats thermal bridges and provides the structure with greater thermal inertia.
In Switzerland, where energy standards are strict and attention to detail is paramount, opting for quality exterior insulation is a wise investment. Here are some of the finest, high-performance materials we use.

Glass or rock wool

Wool, whether rock or glass, is renowned for its excellent insulating properties. Thin and light, it offers first-rate thermal and acoustic insulation. It is also fire-resistant, enhancing building safety.

Wooden panels

In addition to being a natural, renewable material, wood has remarkable insulating qualities. Wood fiber panels are thin, robust and naturally regulate humidity, guaranteeing optimal interior comfort.

Spaceloft panels

spaceloft panels made from silica aerogel are between 10 and 90 mm thick. They are specially designed for use in narrow spaces such as interior rooms or window openings.

Expanded or extruded polystyrene

Expanded or extruded polystyrene is particularly appreciated for its lightness and ability to provide effective insulation against cold and heat. Its thinness and ease of installation make it a preferred choice for projects requiring speed and efficiency.

Cellulose wadding

Made from recycled paper, cellulose wadding is a high-quality, environmentally-friendly, high-performance insulator. Its fine texture makes it easy to install, and its insulating properties are comparable to those of mineral wools. It also offers good protection against noise pollution.

Stages of interior insulation work

Interior insulation is a technical task which, when carried out properly, radically transforms the thermal comfort of a home. As experts in the field, we have refined our process to ensure impeccable implementation. Here are the four essential steps in our method:

Diagnosis and analysis

Every building is unique. That’s why we start with a detailed assessment of your home’s interior. This allows us to understand the layout, identify areas requiring special attention, and determine the most appropriate thickness and type of insulation.

Surface preparation

Before installing insulation, it’s essential to prepare the walls properly.
This includes cleaning, rectifying irregularities and, if necessary, installing a vapour-barrier membrane to protect the insulation from damp.

Installing interior insulation

Depending on the material chosen and the specifics of the home, the insulation is either fixed directly to the walls or mounted on a pre-installed framework.
This step is carried out with surgical precision to guarantee complete coverage, thus avoiding thermal bridges.

Cladding and finishes

After installing the insulation, we apply the finishing cladding, whether plasterboard, wood panels or other options.
This process gives your spaces a neat, elegant look, while ensuring that the insulation is protected.

ALL ABOUT INTERIOR INSULATION

WHAT ARE THE ADVANTAGES OF INTERIOR INSULATION?

Interior insulation, which is very popular in Switzerland, has undeniable advantages:

  • Increased thermal comfort: It guarantees a stable indoor temperature, providing protection from the harsh Swiss winters and summer heat.
  • Reduced energy costs: By minimising heat loss, it significantly reduces heating and air-conditioning bills.
  • Discretion and aesthetics: Unlike external insulation, the internal solution preserves the external appearance of buildings, an asset for heritage buildings in Switzerland.
  • Moisture barrier: It regulates ambient humidity, preventing the unpleasant effects of condensation and mould.
  • Soundproofing: As well as providing thermal insulation, it reduces external noise, providing a haven of peace in an urban environment.

In Switzerland, where quality of life and compliance with energy standards are paramount, interior insulation is the solution of choice for any home.

HOW MUCH DOES INTERIOR INSULATION COST?

The cost of interior insulation depends on a number of factors, including the materials used, the complexity of the project and the labour involved. Prices generally vary between CHF 100 and 350 per square metre. This cost includes materials, installation and ancillary work. The choice of materials and the quality of installation can influence thermal performance and energy savings. For an accurate estimate tailored to your project, it is advisable to consult several professionals and ask for detailed quotes.

ARE THERE ANY GRANTS AVAILABLE IN GENEVA FOR INTERIOR INSULATION?

In Geneva, grants for interior insulation depend on the CECB+. Grants may be awarded on the basis of specific criteria linked to the CECB+, but they are not systematically obtained. For details and eligibility, we recommend that you consult the relevant authorities in Geneva.

HOW LONG DOES INTERIOR INSULATION LAST?

Interior insulation lasts for around 30 years. Of course, this can vary depending on the quality of the materials used, environmental conditions and maintenance carried out over the years. To ensure optimum performance, it is advisable to check the condition of the insulation regularly and carry out any necessary repairs.

HOW CAN YOU SPOT FAULTY INTERIOR INSULATION?

Faulty interior insulation often manifests itself in the form of thermal bridges. These uninsulated or poorly insulated areas lead to heat loss. The direct consequence of these thermal bridges is the appearance of mould, a sign of excessive damp and poor insulation. It is therefore essential to keep an eye on these signs so that you can intervene quickly to ensure effective insulation.
