What materials make up the ITE in Bordeaux?

In a context where energy performance and thermal comfort are becoming priorities for residents of Bordeaux and its surrounding areas, external thermal insulation (ETI) is emerging as an essential solution. This technique not only optimizes the energy consumption of homes but also enhances the appearance of facades by giving them a new lease of life. However, successfully implementing an ETI project requires a thorough understanding of the materials used, adapted to local climatic and architectural constraints. Bordeaux, with its specific standards, mild but humid climate, and an urban fabric blending old and contemporary buildings, requires that each material choice be carefully considered to ensure durability and efficiency. Understanding the specific characteristics of the insulation materials available on the market is essential to benefit from the best performance while complying with the standards of the 33 department. Discover in this article a complete overview of the preferred materials in Bordeaux for ETI, their characteristics, as well as the personalized solutions that Ravalement Bordeaux – Ravalement33 offers to support you through every step of your renovation.

External thermal insulation must ensure a perfect balance between quality, durability, and adaptability to the local climate. In Bordeaux, where ambient humidity and temperature fluctuations are key factors, the choice of insulation materials is not left to chance. Ravalement Bordeaux – Ravalement33 offers several insulation solutions that meet the thermal and environmental performance requirements set for 2025.

Among the most common insulation materials, certain suppliers stand out for their expertise and the quality of their products. Here are the main ones:

🌿

• Rockwool (Rockwool, Rocksil): This mineral material has the advantage of being non-combustible, highly resistant to impact and weathering, with an insulating power of between 0.033 and 0.044 W/m.K. Its robustness makes it an ideal choice for buildings subject to the strictest fire standards. 🧱 Expanded polystyrene (Knauf, Saint-Gobain):
• Lightweight, affordable, and high-performance (0.031 to 0.038 W/m.K), it is widely used for simple and economical insulation. Its main drawback is its sensitivity to impacts and chemical agents. 🍃 Wood wool (Ecovent):
• A natural and recyclable insulation material, it has an excellent environmental impact. Its coefficient ranges from 0.036 to 0.046 W/m.K, providing good thermal insulation while regulating humidity. 🌰 Expanded cork:
• Naturally rot-proof and hydrophobic, this material is more expensive but remains an excellent solution for eco-friendly buildings and those exposed to humidity. 💨 Cellulose wadding:
• Made from recycled paper, it stands out for its ability to regulate humidity and its fire resistance. Since its installation requires blown-in air, it’s best suited for specific renovations. 🔬 Glass wool (Isover, Maviflex):
• Very lightweight, environmentally friendly thanks to recycled glass, and offering good thermal insulation (0.032 to 0.046 W/m.K), it is a safe bet for the general public, despite its current recycling limitations. These materials offer various technical advantages, but their choice also depends on the nature of the walls to be insulated and the surrounding environment. Some materials, such as rock wool or wood wool, are more suitable for tall facades, while polystyrene or cork are preferred for residential walls. Insulation Material Origin

After the insulation has been installed, the longevity and aesthetic success of exterior thermal insulation depend largely on the finishing and protective materials. These layers play an essential role in protecting the insulation panels from external aggressions: UV rays, rain, impacts, and dirt. They also define the final appearance of the facades.

Traditional or thin coatings:

Covering the insulation, they provide effective protection while offering a wide range of textures and colors adapted to urban planning regulations. These coatings can be applied with lime, cement, or a natural version for historic buildings, which is common in the Bordeaux metropolitan area.

• 🪵 Wood or composite cladding (BatiGroupe): Durable and aesthetic, cladding creates a contemporary effect. It offers high resistance to weathering and can be combined with bio-based insulation. 🧱
• Fiber-cement cladding and panels (Sika): These robust materials protect facades exposed to strong winds and add a designer touch to modern buildings. 🔧
• Specific facade paints (Thermotech): Applied after renovation, they contribute to waterproofing and protecting walls. Modern paints provide increased resistance and a diverse color palette while allowing the facade to breathe. The choice of these materials must take several criteria into account:
• Compatibility with the chosen insulation to avoid any deterioration. Regulatory constraints imposed by the Bordeaux City Hall, particularly in protected areas. Local climatic conditions: humidity, dirt, wind exposure.
