Why choose aerogel plaster?
Aerogel is an innovative material offering exceptionally low thermal conductivity, placing it at the top of the range of insulating materials available on the market. Resembling a gel in which the liquid is replaced by gas, its low density and insulating properties make it unrivalled for insulating the facades of older buildings in particular.
Silica aerogel stands out for its ability to interrupt thermal conduction, thermal radiation and convection. Compared with other materials, it is twice as insulating as glass wool. Buildings treated with this insulating plaster can therefore achieve energy savings of up to 50%, reducing energy costs and promoting an eco-responsible approach.
Opting for aerogel plaster in Geneva means choosing excellence in insulation, combining performance, durability and aesthetics.
Application process for exterior insulating plaster in Aerogel
Applying aerogel exterior insulating render is a meticulous process that requires expertise and precision.
Each step is essential to guarantee optimum insulation and an impeccable aesthetic finish.
Making an appointment
Before any work is carried out, it’s essential to make an appointment in advance at your home or building. This will enable us to assess the current state of your façade, understand your specific needs and determine the best approach for applying thermally insulating rendering. It’s also an opportunity to discuss the benefits of aerogel, answer any questions you may have, and propose an appropriate quote.
Plastering your facade using our plastering machine
Once the consultation has been completed and the project validated, application begins. Using a spray machine specially designed for this type of rendering, the aerogel insulating plaster is applied evenly over the entire facade. This technique ensures uniform coverage, even in the most inaccessible areas.
Aerogel is applied in a thin, even layer
The effectiveness of aerogel lies in its ability to insulate even in thin layers. A thin layer of just 30 mm is all that’s needed for optimum insulating performance. This thinness also preserves the aesthetics of the building, while guaranteeing first-rate thermal protection.
ALL YOU NEED TO KNOW ABOUT AEROGEL INSULATING PLASTER
WHAT ARE THE ADVANTAGES OF AEROGEL?
Insulating an aerogel façade with Bertolit offers a multitude of benefits, both for your comfort and for the longevity of your building:
- Superior thermal performance: Aerogel has one of the lowest thermal conductivities of all insulating materials, guaranteeing an effective barrier against cold and heat.
- Reduced thickness: Thanks to its effectiveness, a thin layer of aerogel is all you need to achieve results comparable to thicker insulation materials, preserving interior space.
- Moisture resistance: Aerogel repels water, preventing moisture and mould problems and extending the life of the structure.
- Lightweight: Its low density makes it particularly light, making it easy to handle and install, without overloading structures.
- Durability: UV and weather resistant, aerogel retains its insulating properties over time, without degrading.
- Environmentally-friendly: Its manufacture requires less energy than other insulating materials, and its longevity reduces the need for frequent replacement, contributing to an environmentally-friendly approach.
- Non-combustible: Aerogel is non-combustible, offering added security against fire risks.
- Flexibility: Despite its porous structure, aerogel is flexible, making it suitable for a variety of applications, including irregular surfaces and complex geometric shapes.
- Reduced thermal bridges: Its ability to be applied continuously eliminates thermal bridges, areas often overlooked with other insulation methods.
- Improved quality of life: by effectively regulating interior temperature, aerogel contributes to greater thermal comfort for occupants.
HOW MUCH DOES AEROGEL PLASTERING COST?
Aerogel plaster is usually applied to replace existing conventional plaster, which has to be jackhammered and removed to make way for the insulating plaster. The service of pricking out this old plaster and re-applying the 30 mm thick insulating Aerogel plaster represents a budget of around CHF 400.00 to 500.00 per m2.
AM I ENTITLED TO A SUBSIDY FOR AEROGEL PLASTER IN GENEVA?
A study such as the CECB+ may enable you to obtain subsidies: in fact, the Cantonal Energy Certificate for Buildings is a real thermal assessment of a building's envelope, which is the only way of assessing entitlement to a subsidy, while quantifying it, and is the starting point for the process.
