Polyurethane Rock Wool Sandwich Panel is a composite panel that combines the advantages of both polyurethane foam and rock wool. This type of panel is widely used in construction, cold chain logistics, industrial plants, and other applications due to its excellent insulation, soundproofing, fire resistance, and environmental benefits.

1. Structure and Materials:

• Outer Layers: The outer layers of the Polyurethane Rock Wool Sandwich Panel are typically made of steel, aluminum, or other metal sheets, providing mechanical strength and corrosion resistance.
• Core Materials: The core consists of polyurethane foam and rock wool, where the polyurethane foam offers superior thermal insulation, and the rock wool enhances fire resistance and soundproofing.

2. Key Features:

1. Superior Insulation Performance: Polyurethane foam has a very low thermal conductivity, which provides excellent thermal insulation, effectively reducing energy loss and minimizing the need for additional heating or cooling.
2. Excellent Fire Resistance: Rock wool has high fire resistance and can withstand elevated temperatures without burning, making it ideal for high-temperature environments and buildings with stringent fire safety requirements.
3. Soundproofing: The fibrous structure of rock wool provides excellent sound insulation, reducing noise transmission, making it suitable for sound-sensitive applications such as factories, music halls, and auditoriums.
4. Moisture Resistance: The closed-cell structure of rock wool makes the panel highly resistant to moisture, preventing issues like mold growth and material degradation.
5. Environmental Friendliness: Polyurethane Rock Wool Sandwich Panels meet environmental standards. The rock wool is made from natural minerals, free of harmful chemicals, and the production process is energy-efficient, making it a green building material.

3. Applications:

1. Building Facades and Roofing: Polyurethane Rock Wool Sandwich Panels are commonly used for building facades, roofs, and walls to provide thermal insulation and reduce energy consumption, improving the building’s energy efficiency.
2. Cold Chain Logistics and Cold Storage: Due to its excellent insulation properties, this panel is widely used in cold storage facilities, refrigerated transportation, and cold chain warehouses to maintain stable temperatures and preserve the quality of stored goods.
3. Industrial Facilities: Polyurethane Rock Wool Sandwich Panels are used in various industrial applications where both fire resistance, insulation, and soundproofing are critical, such as factories, warehouses, and data centers.
4. Fire Safety Projects: Given their excellent fire resistance, these panels are ideal for use in buildings with high fire safety requirements, such as hospitals, schools, and shopping malls.
