Wood fiber is becoming an increasingly popular insulation material, thanks to its many advantages in terms of energy savings and thermal comfort. This natural, environmentally-friendly material offers excellent thermal insulation performance significantly reducing heat loss in buildings.
In addition, wood fiber regulates ambient humidity, ensuring greater indoor comfort. In this article, we invite you to discover all the benefits of wood fiber insulation, and how it can help improve the energy efficiency of your home.
Manufacturing process for wood fiber from ground wood shavings humidified with steam
The manufacture of wood fiber begins with the wood chip grinding The chips are then moistened with steam to soften them. This process facilitates defibration of the chips, which consists in separating the cellulose fibers from the wood.
Once the fibers have been extracted, they are mixed with an organic or inorganic binder to form wood fiber sheets. This material is widely used in industry to manufacture particleboard, cardboard, insulation and many other products.
Advantages of wood fiber insulation
Wood fiber is renowned for its excellent acoustic insulation properties making it an ideal material for reducing noise pollution inside buildings. In addition, its ability to absorb moisture without alteration makes it a perfect insulator for regulating humidity levels in interior spaces.
Finally, with a thermal conductivity of up to 36 mW/(m.K)wood fiber provides effective thermal insulation, limiting heat loss and generating significant energy savings.
Performance and environmental sustainability of wood fiber
The environmental sustainability of wood fiber is also a strong argument in favor of its use. Indeed, this material is renewable and recyclable. This helps to reduce the carbon footprint of construction and renovation projects. What’s more, wood fiber is often sourced locally, thus promoting the circular economy and sustainable development. at regional level.
The ecological dimension of wood fiber makes it an increasingly attractive choice for those wishing to combine thermal performance with respect for the environment in their real estate projects.
The look health and comfort is also a major advantage of wood fiber insulation. Unlike some synthetic materialswood fiber does not release toxic substances or particles harmful to health. It therefore helps improve indoor air quality by limiting the risk of allergies and respiratory problems.
Rates and subsidies available for wood fiber insulation installation
On average, the cost of installing wood fiber insulation varies from between 20 and 50 euros per square meter, depending on the complexity of the work and the quality of the materials used. However, it is important to note that various forms of financial assistance are available to support this type of project.
These include MaPrimeRénov’, the Energy Savings Certificates (CEE), Zero interest rate eco-loan and reduced VAT rate of 5.5. To qualify for these subsidies, it is generally necessary to meet certain eligibility criteria linked to income, the nature of the work and the targeted energy performance.
