Sandwich panels are composite building materials commonly used in construction and industrial applications. They consist of two outer layers, known as facings or skins, and a core material in between. The facings are typically made of metal, such as aluminum or steel, while the core material can be foam, polyurethane, or mineral wool. These panels offer excellent insulation properties, structural strength, and fire resistance. Manufacturers, suppliers, and sellers of sandwich panels include a wide range of companies in the construction and building materials industry. Some well-known manufacturers include Kingspan, Metecno, Tata Steel, and ArcelorMittal. These companies produce sandwich panels in various sizes, designs, and specifications to meet different project requirements.
