Proven long-term durability, even over the extended wheelbase of an L3H3

The Armaflex ChezMoi insulates your L3H3 van from floor to ceiling, including the walls and reinforcements.

On the doors, the Armaflex ChezMoi gives way to the Biofib Trio: this natural fibre panel (hemp, flax, cotton) retains its insulating volume even after thousands of kilometres, a key point on a large van subject to greater vibrations. A vapour retarder completes the installation to prevent condensation against the metal sheet. Cork insulates the floor. Quantities already calibrated for this format, adhesives and accessories included.

Compatible with L3H3 vans on the market (Renault Master, Fiat Ducato, Citroën Jumper, Peugeot Boxer, Ford Transit, Mercedes Sprinter, Volkswagen Crafter and equivalents), this kit covers walls, ceiling, doors, wheel arches and floor.

• Quantities calibrated for an L3H3: no calculations needed on your part, even for this large format.
• Armaflex ChezMoi, designed for the van: unlike the former AF, which was designed for construction.
• Does not compress over time: the Biofib Trio retains its insulating volume over the kilometres.
• Insulation that covers everything: walls, ceiling, doors, wheel arches and floor.
• Designed and manufactured in France: hemp, flax and cotton, 85% French-sourced.

Materials chosen for their role in insulation

Armaflex ChezMoi — the insulation designed for the van

The successor to the Armaflex AF, the ChezMoi uses the same closed-cell technology in a formulation designed from the outset for van conversions rather than construction. Its integrated vapour barrier means there is no need to add a separate vapour retarder to the walls and ceiling.

• Role in the kit: walls, ceiling, reinforcements, wheel arches
• Thickness / packaging: 19 mm (6 m² roll) and 10 mm (10 m² roll)
• Thermal conductivity (λ): 0.035 W/(m·K)
• Integrated vapour barrier: closed cells, no vapour retarder to add
• Antimicrobial treatment: Microban®, integrated into the material
• Service temperature: -50 °C to +85 °C
• VOC emissions: A+ rating (ISO 16 000)
• Manufacturer's warranty: 10 years
• Origin / manufacture: Europe, Armacell technology

Biofib Trio — the natural insulator for hard-to-reach areas

Made from hemp, flax and cotton (85% French-sourced), the Biofib Trio is designed and manufactured in France. Its natural hygroscopic regulation helps prevent excess moisture in the vehicle, and its structure does not compress even after thousands of kilometres.

• Role in the kit: doors
• Thickness / packaging: 45 mm (0.75 m² panel)
• Density: 30 kg/m³
• Thermal conductivity (λ): 0.038 W/(m·K)
• Thermal resistance (R): 1.15 m²·K/W
• Hygroscopic regulation: yes, permeable to water vapour (µ ≤ 2)
• Long-term durability: does not compress, natural spring-back effect
• Origin / manufacture: France, 85% French supply chain (hemp, flax, cotton)

Cork — the natural floor insulator

Naturally rot-proof and moisture-resistant, cork insulates the floor without adding unnecessary thickness. Its lightness and flexibility make it an easy solution to apply with spray adhesive, directly onto the metal sheet.

• Role in the kit: floor
• Thickness / packaging: 4 mm (4 m² roll)
• Moisture resistance: rot-proof, naturally water-resistant
• Origin / manufacture: natural material
