Cellulose panel: why choose this ecological and efficient insulation

The panel cellulose jump is an innovative solution for energy renovation works, combining thermal performance and respect for the environment. Coming from recycled documents and natural adjuvants, this biological material meets the requirements of buildings for high energy performance (HPE) by limiting its ecological imprint. Its use is widespread in the walls and internal roofs, in particular thanks to its ability to adapt to the complex forms of old structures.

Technical characteristics of the cellulose sail of the panel

Ecological composition

The cellulose is composed of cellulose fibers from recycled and crushed recycled cards, mix with natural additives (Borace, ammonium phosphate) to improve its fire resistance and insects. Unlike synthetic insulators such as polyurethane or polystyrene, it does not contain No aggressive chemical And of course degrades at the end of life.

Thermal and phonic performances

With Thermal conductivity (λ) of 0.035 W/MKThe cellulose vagabond offers thermal resistance (R) of 5.7 m².k/W For a thickness of 20 cm. Although slightly lower than that of wood fiber (λ = 0.036 w/mk), it stands out for a 10 hours phase thermal shyutingIdeal for regulating temperature variations in summer.

Advantages of the cellulose panel

Ecology and sustainability

RGE and Libibat certificatesThis solution meets the aid criteria for the renewal of energy. His Reduced carbon impact (recycled raw material) and is sustainability (Mold with mold and insects) make it a lasting choice for old or new buildings.

Ease of installation

Available in Rigid or semi-riigid panelsCellulose adapts to different insulation techniques:

• Boring : Fix on a wooden or metal structure for the internal walls.
• Projected : Direct application on irregular walls or lost attic.
• Insulating : Complement to limit thermal bridges.

Practical applications

Attic insulation

In the lost attic, the wandering of the cellulose booty is soup To fill the interstices between the beams, eliminating thermal bridges. A The elevation of Vph (Value of the house floor) and the installation of deflectors At the base of the beams optimizes its effectiveness.

Insulation of the internal walls

For stone walls or blocks, a Wooden frame It is mounted, followed by the installation of cellulose panels. This method allows:

• Preserve the living space (Minimum thickness of 15 cm).
• Integrate technical networks (electricity, hydraulic system) in the technical space.

Minimum thickness

For Optimal insulationfavor:

• 15 cm in the panel For the internal walls.
• 20 cm and VRAC For the attic.

Certifications and seats

Opt for Craftsman rge To ensure an installation according to the standards (laying of air seal membranes, thick control). Avoid self -regulation to limit the risks of condensation or from settlement.

The cellulose vagabond of the Panel Incarna a ecological transition success in the isolation area. His Balance between thermal performance, respect for the environment and ease of installation In fact, an essential choice for the renovation of old or new buildings. Although its cost is slightly higher than that of synthetic insulators, it is sustainability and his Reduced impact on the planet Make it a long -term long -term value.
