Extruded polystyrene (XPS) sandwich panels are building materials that consist of a core made of extruded polystyrene foam sandwiched between two outer layers, typically made of metal or other suitable materials. XPS foam is a rigid insulation material known for its thermal insulation properties and strength.

Here are some key features of extruded polystyrene sandwich panels:

• Thermal Insulation: XPS foam has excellent thermal insulation capabilities. Its closed-cell structure minimizes heat transfer, providing effective insulation and energy efficiency in buildings.

• Lightweight and High Strength: XPS sandwich panels are lightweight, making them easy to handle and install. Despite their lightness, they offer high structural strength and durability.

• Moisture Resistance: XPS foam is moisture-resistant and does not absorb water easily. This property helps prevent the growth of mold, mildew, and rot, making it suitable for applications in areas with high humidity or moisture exposure.

• Dimensional Stability: XPS foam has low thermal expansion and contraction rates, ensuring the dimensional stability of the sandwich panels over time. This reduces the risk of cracks or gaps in the construction.

• Fire Retardant: XPS foam is treated with fire-retardant additives during the manufacturing process, enhancing its fire resistance. It contributes to the overall fire safety of buildings.

• Versatility: XPS sandwich panels are versatile and can be used in various applications, including walls, roofs, floors, and cold storage facilities. They provide both thermal insulation and structural support.

XPS sandwich panels are commonly used in commercial buildings, industrial facilities, residential constructions, cold rooms, and other structures where thermal insulation and strength are important factors. They offer excellent energy efficiency, moisture resistance, and durability, making them a popular choice for construction projects.
