Introduction to Sandwich Panels
Sandwich panels are composite materials consisting of two outer layers (facings) and an inner core material. The facings are typically made of metal, such as steel or aluminum, while the core can be made of various materials like polyurethane (PU), polystyrene (EPS), mineral wool, or fiberglass. These panels offer several advantages, including high strength-to-weight ratio, excellent insulation properties, fire resistance, and ease of installation. They are widely used in the construction industry for roofing, wall cladding, cold storage facilities, clean rooms, and modular buildings.
