Why insulate a flat roof?

Insulating a flat roof is much more than a simple step in the construction of a building or house; it’s a strategic investment for any homeowner in Geneva.
Firstly, it’s synonymous with energy efficiency. By minimizing heat loss, you reduce your heating costs in winter and air-conditioning costs in summer, guaranteeing constant indoor comfort. Thermal stability also means greater protection against the vagaries of the weather, extending the life of your roof. From an environmental point of view, optimal roof insulation reduces your carbon footprint, in line with current ecological concerns. What’s more, in Geneva as in the rest of Switzerland, compliance with energy standards is essential to preserving the country’s ecosystem. A well-insulated roof ensures that your building complies with current regulations, while enhancing the value of your property on the real estate market. Finally, beyond the thermal aspect, insulation offers appreciable acoustic peace of mind, attenuating outside noise pollution. At Bertolit, we understand the importance of these issues and are committed to providing flat roof insulation solutions tailored to the specific needs of our customers.

Insulating your flat roof

At Bertolit, we believe that every insulation project is unique. That’s why we’ve developed a rigorous, personalized process to ensure that every customer receives an insulation solution tailored to their specific needs.

Initial consultation

It all starts with a meeting. Before proposing a solution, we take the time to understand your needs, your concerns and the specifics of your building. This initial consultation allows us to assess the current condition of your roof, identify areas requiring special attention and discuss your energy efficiency goals.

Selecting insulating materials

Following our consultation, Bertolit’s team of experts focuses on selecting the ideal materials for your flat roof insulation project. We give preference to insulating materials such as rock wool and polyurethane foam, primarily on the basis of their performance and suitability for your building. At Bertolit, quality is paramount. By considering Geneva’s specific climatic conditions, the structure of your property and your budget, we aim to offer an insulation solution that perfectly meets your requirements while optimizing energy performance.

Removal of old insulation, if necessary

Before starting any insulation project, it’s essential to assess the condition of the existing insulation. In some cases, previously installed insulation may have aged, been damaged or no longer performs as expected. At Bertolit, we take this step very seriously. The process begins with a thorough inspection to determine the need to remove the old insulation. If removal is necessary, our experts proceed with caution to avoid damage to the building’s structure. The possible presence of pollutants (asbestos, HBCD, PAHs, etc.) in the old insulation and waterproofing materials is also a question to be asked, etc. Worn-out or defective materials are then disposed of responsibly, in compliance with environmental standards. Once this stage is complete, the site is prepared for installation of the new insulation. This preparation ensures that the new insulation fits perfectly, offering maximum efficiency. By choosing Bertolit, you ensure a smooth transition from old to new insulation, guaranteeing the safety and efficiency of your project.

Installing new roof insulation

Insulation installation is a fundamental step in guaranteeing an effective thermal barrier. Our experts ensure uniform installation, eliminating the risk of thermal bridges. After this first step, we apply a waterproofing membrane, essential for protecting the insulation from water infiltration and ensuring its durability. Finally, to complete the job and provide an impeccable finish, a finishing coat of ballast is carefully applied. This not only enhances the roof’s protection, but also lends a refined aesthetic to your building. With Bertolit, every detail counts to guarantee perfect insulation.

WHAT ARE THE ADVANTAGES OF INSULATING A FLAT ROOF?

Insulating a flat roof with Bertolit offers a multitude of benefits, both for your comfort and the durability of your building:

Increased energy efficiency: Thanks to high-quality insulation panels, heat loss in winter is minimised and heat penetration in summer is limited. The result: significant savings on your heating and air-conditioning bills.
Indoor comfort: With a well-designed insulation system, temperature variations are a thing of the past! You benefit from a stable indoor temperature, protected from excess condensation and humidity.
Protection from the elements: As well as providing comfort, insulation also acts as a weather barrier. Whether it's rain, snow or wind, your roof, reinforced by a suitable coating, is better able to withstand the elements.
Reduced carbon footprint: By optimising energy consumption, you're actively helping to reduce polluting emissions, thereby protecting our environment.
Enhancing the value of your property: A roof made of wood or with insulated decking is a major asset when selling or renting. It is a sign of quality renovation and attention to the building's sustainability.
Regulatory compliance: Geneva, like other regions, imposes energy standards. A properly insulated flat roof will ensure that your property complies, protecting you from penalties. (CHF 70.00 /m2)
