Sandwich Panels are composite building materials consisting of two outer layers (usually metal) and an insulating core (such as polystyrene, rock wool, or polyurethane). They are widely used in construction for walls, roofs, and partitions due to their excellent insulation, strength, and lightweight properties.
• Material: Outer layers made of galvanized steel, aluminum, or stainless steel; core materials include rock wool, polyurethane (PU), or expanded polystyrene (EPS).
• Thickness: Typically ranges from 30mm to 150mm, depending on insulation requirements.
• Applications: Used in cold storage, warehouses, industrial buildings, and residential buildings.
• Advantages: High thermal insulation, soundproofing, fire resistance, and quick installation.
Sandwich panels provide an efficient, durable, and cost-effective solution for modern construction needs.
