Natural insulation without compromise

Armaflex ChezMoi insulates your L4H3 van from floor to ceiling, including the walls and structural supports.

On the doors, Armaflex ChezMoi gives way to Biofib Trio: this natural fibre panel (hemp, linen, cotton) effectively insulates the hard-to-reach corners of your van's doors. A vapour check protects the whole assembly from condensation. Cork insulates the floor. Quantities already calibrated for this size, adhesives and accessories included.

Compatible with L4H3 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 L4H3: no calculations required on your part, even for this large format.
• Armaflex ChezMoi, designed for the van: unlike the old AF designed for construction.
• Does not compress over time: Biofib Trio retains its insulating volume over thousands of kilometres.
• Insulation that covers everything: walls, ceiling, doors, wheel arches and floor.
• Designed and manufactured in France: hemp, linen and cotton, 85% from French supply chains.

Materials chosen for their insulating properties

Armaflex ChezMoi — the insulator designed for the van

The successor to Armaflex AF, ChezMoi uses the same closed-cell technology, in a formulation designed from the outset for van conversion rather than construction. Its integrated vapour barrier eliminates the need for a separate vapour check on the walls and ceiling.

• Role in the kit: walls, ceiling, structural supports, 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-cell, no separate vapour check required
• 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, linen and cotton (85% from French supply chains), 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, vapour-permeable (µ ≤ 2)
• Long-term durability: does not compress, natural spring effect
• Origin / manufacture: France, 85% from French supply chains (hemp, linen, 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 easy to install 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
