For a vehicle using 40 m² of these panels, this translates into a weight saving of 160 kg—the equivalent of two additional passengers or significantly enhanced equipment capacity. Optimal Thermal Insulation:With a thermal conductivity of just 0.034 W/mK, the panel provides excellent insulation. It keeps interiors comfortable under extreme conditions, whether in scorching deserts or icy regions. Sustainability as a Standard:The recycled PET core and bio-based flax-fiber face sheets set new benchmarks for eco-friendly materials. Our 4x4 Exterior Panel combines sustainability with outstanding performance—without compromises. Superior Strength and Load Capacity:The innovative panel structure offers exceptional load-bearing capacity and high resistance to mechanical stresses, making it ideal for use in demanding off-road and expedition environments. Flexibility and Easy Processing:The paint-ready finish saves time and effort during further processing. Panels can also be ordered in custom sizes to meet the specific requirements of any project.
