EPS Sandwich Panel Manufacturer | Lightweight Building Materials Supplier

EPS Sandwich Panel

EPS Sandwich Panels combine an Expanded Polystyrene (EPS) core with metal facings for temperature-controlled construction applications. The EPS core forms through inflating micro-granular polystyrene with water vapor and pentane gas, creating tightly bonded granules with trapped air in closed-cell pores. Metal cladding options include pre-painted galvanized steel, stainless steel, or aluminum in RAL colors.

Available thicknesses range from 50mm to 200mm with standard 1120mm width and customizable lengths. The EPS core delivers thermal conductivity of approximately 0.038 W/mK, providing effective insulation for cold storage environments. The closed-cell structure resists moisture ingress and prevents fungal growth while maintaining lightweight handling characteristics.

Interlocking connection systems create airtight seals between panels through tongue-and-groove profiles or cam-lock mechanisms. Installation accommodates vertical or horizontal orientation with modular assembly that reduces labor time. Panels connect by fitting together and securing with fastening systems like Allen key-operated cam locks.

Primary applications include walls, ceilings, and partitions in cold rooms, freezers, food processing facilities, and pharmaceutical storage. The panels support temperatures from refrigerated to freezing conditions while meeting hygiene standards for food safety. Surface materials resist oils, chemicals, and solvents, inhibiting bacterial growth in sensitive environments.

Frequently Asked Questions（FAQS）

What are the key advantages of EPS sandwich panels for cold storage?

EPS sandwich panels are lightweight and offer excellent thermal insulation. They have an interlocking connection system at the joints, are easy to install, and are cost-effective for interior cold storage applications. The panels are also known for their flexibility and can be combined with other panel types to optimize project costs.

What temperature range are EPS sandwich panels suitable for?

EPS panels are commonly used in cold storage applications. While specific EPS temperature ranges aren't detailed in our sources, cold room panels in general are designed for environments ranging from normal operating temperatures down to -36°C for freezer rooms.

What thickness options are available for EPS sandwich panels?

EPS panels are offered in thicknesses ranging from 2 inches to 10 inches (approximately 50mm to 250mm), with common thicknesses including 50mm, 75mm, 100mm, 120mm, 150mm, and 200mm.

How do EPS panels compare to PU or PIR panels for cold storage?

EPS panels are cost-efficient and offer more flexibility for installation compared to other insulation materials. They allow for large build-outs with maximum spans up to 45 feet per panel. While PU and PIR panels typically offer higher R-values, EPS provides an effective thermal barrier with excellent cost-performance ratio for many applications.

What applications are EPS sandwich panels best suited for?

EPS panels are ideal for large warehouses, processing facilities, and extreme-height cold storage applications. They are also suitable for healthcare facilities, food banks, and distribution warehouses where cost-effective thermal insulation is required.

Can EPS sandwich panels be customized for specific project requirements?

Yes, cold room panels can be customized in terms of width, thickness, and length to meet specific requirements. The length can be tailored from 0.5m to 18m, with standard shipping length of 12 meters for international clients. Custom colors are also available according to international RAL color charts.

What installation methods are used for EPS sandwich panels?

EPS panels feature an interlocking connection system at the joints for easy installation. The panels are designed for quick and efficient assembly, helping to reduce labor costs and installation time significantly.

How can your EPS panels help reduce operational costs for our cold storage projects?

EPS panels are cost-efficient and offer easy installation, which minimizes labor costs and energy consumption due to their good insulation properties. The interlocking connection system ensures quick assembly, reducing overall project time and expenses.

What support do you provide for technical specifications and customization needs?

We offer panels that can be designed for various spans and thicknesses to meet specific project requirements. Our in-house R&D capabilities allow for detailed technical data and custom solutions, ensuring compatibility with your design specifications.
