What are static caravans made from?

Static caravans are primarily constructed from a steel chassis and are typically built using materials such as wood, aluminum, and fiberglass for the exterior. The walls are often made of a combination of insulation and plywood or composite materials, while the interiors feature drywall or paneling. Windows are usually double-glazed for energy efficiency, and the roofs can be made from various materials like felt or metal. Overall, the construction aims to provide durability, insulation, and comfort for seasonal or permanent living.
