Introduction

Product Overview

PU Sandwich Panels (Polyurethane Sandwich Panels) are high-performance insulated panels designed for industrial buildings, commercial facilities, cold storage warehouses, and temperature-controlled environments. Featuring a rigid polyurethane (PU) foam core sandwiched between two steel facings, these panels provide excellent thermal insulation, lightweight construction, and durable protection.

With low thermal conductivity and strong insulation performance, PU sandwich panels reduce heat transfer, improve energy efficiency, and maintain stable indoor temperatures. Their prefabricated design enables fast installation, while precision-engineered panel joints help improve airtightness and overall building performance.

Key Feature

1. Excellent Thermal Insulation
The rigid PU foam core has low thermal conductivity, reducing heat transfer and improving building energy efficiency.

2. Lightweight & Durable
The combination of a rigid insulation core and steel facings offers a strong, lightweight panel structure suitable for various building applications.

3. Airtight Joint Connection
Precision-designed panel joints help minimise air leakage and support stable indoor temperatures when properly installed.

4. Fast & Easy Installation
The prefabricated panel design simplifies on-site assembly, reduces construction time, and improves installation efficiency.

5. Customizable Specifications
Available in different thicknesses, steel facing options, colours, surface finishes, and dimensions to meet specific project requirements.

6. Wide Range of Applications
Suitable for industrial workshops, warehouses, cold storage facilities, food processing plants, commercial buildings, and other insulated structures.

FAQ

FAQ

1. What is a PU sandwich panel? A PU sandwich panel is an insulated building panel consisting of a rigid polyurethane (PU) foam core

bonded between two metal facings. It provides excellent thermal insulation, a lightweight structure, and efficient installation for various building applications.

2. What are the main advantages of PU sandwich panels? PU sandwich panels offer excellent thermal insulation, lightweight construction, durable metal facings, convenient installation, and reduced heat transfer. They are widely used in buildings requiring energy-efficient insulation solutions.

3. What thicknesses are available? PU sandwich panels can be manufactured in different thicknesses, such as 50 mm, 75 mm, 100 mm, 150 mm, and 200 mm, depending on the available product range and project requirements.

4. What is the core density of PU sandwich panels? The core density depends on the product specification and manufacturing process. A typical reference value for rigid PU foam is around 40 kg/m³, but the actual density should be confirmed with the manufacturer's technical data sheet.

5. Are PU sandwich panels suitable for cold storage? Yes. PU sandwich panels are widely used in cold rooms, refrigerated warehouses, and temperature-controlled facilities because of their excellent thermal insulation properties. The appropriate panel thickness depends on the required temperature and project design.

6. Can PU sandwich panels be used for both walls and roofs? Yes. PU sandwich panels are available in wall and roof configurations. The appropriate profile, thickness, joint design, and load-bearing capacity should be selected according to the building structure and installation requirements.

7. Are PU sandwich panels fire-resistant? PU foam is a combustible insulation material, and fire performance depends on the foam formulation, panel construction, metal facings, and installation conditions. Please request relevant fire test reports and certifications to verify compliance with your project's requirements.

8. Can PU sandwich panels be customized? Yes. Depending on the manufacturer's capabilities, customization options may include panel thickness, length, width, steel facing thickness, color, surface profile, and joint configuration.

9. How are PU sandwich panels installed? PU sandwich panels are installed using compatible fixing systems and interlocking joints according to the application. Proper alignment, fastening, and joint sealing are important for insulation performance, weather resistance, and airtightness.

10. How can I get a quotation for PU sandwich panels? To receive an accurate quotation, please provide your required panel thickness, dimensions, steel facing thickness, color, application, and estimated order quantity. Drawings or project specifications are also helpful for customized orders.
