Expandable container houses typically use durable, lightweight materials for both structure and finishes. The frame is made of high-strength steel, ensuring stability and longevity. Exterior walls often feature weather-resistant cladding like aluminum or fiberglass-reinforced panels. Interior walls may use plywood or gypsum board, while flooring options include vinyl, laminate, or engineered wood. Insulation materials range from polyurethane foam to eco-friendly options like recycled cotton. All materials are chosen for durability, safety, and sustainability, with many meeting international standards for fire resistance and environmental impact.
