Expanded Polystyrene Sandwich Wall Panel

Detalles Del Producto

Expandable polystyrene (EPS) sandwich panels, also known as polystyrene foam sandwich panels, are a type of lightweight composite panel with closed-cell polystyrene foam as the core material. Expanded polystyrene sandwich wall panel use color-coated steel sheets as the face panels, which are bonded together under high pressure with a high-strength adhesive to form a lightweight composite panel. Its classic “sandwich” structure integrates load-bearing, thermal insulation, waterproofing, and decorative functions.

Structurally, the upper and lower face panels of expanded polystyrene sandwich wall panel is typically made of 0.3mm–1.2mm thick color-coated steel sheets, galvanized sheets, or aluminized zinc sheets. The core material is flame-retardant polystyrene foam with a density of 18–22 kg/m³, manufactured through automated continuous molding machines under high temperature and pressure, followed by edge trimming and grooving processes.

Standard thicknesses for EPS sandwich panels range from 50mm to 200mm, with common widths of 950mm, 1000mm, and 1150mm. Lengths can be customized to project requirements. The panels weigh only 10.0–13.6 kg/m², have a thermal conductivity ≤0.039 W/(m·K), and offer approximately 19 dB of sound insulation (75 mm thick).

Expanded polystyrene sandwich wall panel typically have a fire rating of B2 (self-extinguishing) and can be upgraded to B1 (difficult to burn) by using flame-retardant materials. With advantages such as lightweight, high strength, thermal insulation, convenient construction, and economic and environmental friendliness, EPS sandwich panels are widely used in various locations including large industrial plants, steel structure warehouses, logistics warehouses, cold storage facilities, temporary buildings, and prefabricated houses.

Advantages of Expandable Polystyrene Sandwich Panels

Lightweight and High Strength: Weighing only 10–13.6 kg/m², effectively reducing the load on steel structures and foundation costs.

Excelente aislamiento térmico: The closed-cell EPS core material has a thermal conductivity as low as 0.039 W/(m·K), resulting in significant energy savings.

Highly Efficient Construction: Modular panel design allows for dry on-site installation, reducing construction time by over 40% compared to traditional wet methods.

Economical and Durable: Significant material cost advantages; overall service life can reach over 35 years.

Selection Tips and Compliance Explanation

When selecting materials for project construction, two points require special attention:

• First, EPS sandwich panels are typically classified as B2-class combustible materials, releasing toxic gases at high temperatures. They must not be used in densely populated areas or on the exterior walls of high-rise buildings. If Class A fire resistance requirements are involved (such as in chemical workshops, clean areas for food processing, and high-rise public buildings), rock wool sandwich panels or inorganic core composite panels should be prioritized according to local fire safety regulations.
• Second, proper sealing of panel joints is crucial during installation to prevent moisture intrusion that could lead to core material aging and panel corrosion. This is especially important in high-humidity environments or cold chain logistics warehouses, where the quality of installation directly impacts panel lifespan.

Globally, with the continued promotion of prefabricated buildings and green energy-saving concepts, expandable polystyrene sandwich panels, with their mature cost-effectiveness, will continue to hold a significant market position in budget-sensitive projects.
