Metal Sandwich Panel

What is a Metal Sandwich Panel

A metal sandwich panel is an advanced construction material designed for thermal insulation, structural strength, and weather resistance. It consists of two strong metal outer layers bonded to a core insulation material. These panels are widely used in insulated roofing panels, metal wall panels insulation, and prefab metal panels applications where energy efficiency and durability are essential.

Key Specifications

Components of Metal Sandwich Panels

• Metal Outer Layers

  The external faces of the panel are typically made from galvanized steel or aluminum, providing high strength, corrosion resistance, and a smooth finish. These metal skins can be pre-painted to enhance aesthetics and improve weather resistance. This metal cladding layer protects the core and adds to the panel’s load-bearing capacity.

• Core Insulation Materials

  The core is the heart of the metal sandwich panel, delivering superior insulation and fire resistance. Common core options include:

  • Polyurethane (PU) for outstanding thermal insulation and lightweight properties
  • Polyisocyanurate (PIR) offering enhanced fire resistance and energy efficiency
  • Expanded Polystyrene (EPS) known for affordability and thermal insulation
  • Mineral Wool (Rock wool) providing excellent fireproofing and sound absorption

Each core material impacts panel performance in terms of fire safety, thermal conductivity, and mechanical strength.

Types of Metal Sandwich Panels

At Shanghe, we offer a range of metal sandwich panels designed to fit different insulation and structural needs. Each type features metal outer layers combined with specific core materials, delivering distinct benefits based on your project requirements.

Polyurethane PU Core Panels

PU sandwich panels are widely used for their excellent thermal insulation and lightweight properties. The polyurethane core has a high R-value, providing superior energy efficiency. These panels are ideal for cold storage and refrigerated rooms where temperature control is critical. PU panels also boast good fire resistance, though they are typically rated for limited fire performance compared to mineral wool.

Key Advantages:

• Excellent thermal insulation
• Lightweight and easy to install
• Good moisture resistance

Considerations:

• Fire resistance is moderate; additional fireproof measures may be needed for high-risk areas

Polyisocyanurate PIR Core Panels

PIR sandwich panels share similarities with PU but have a more rigid molecular structure. This gives them higher fire resistance and thermal stability. PIR panels perform well in metal wall panels insulation applications where enhanced fire safety is required, such as commercial buildings and clean rooms.

Key Advantages:

• Higher fire resistance certified to ASTM E84 and EN standards
• Strong thermal performance similar to PU
• Slightly better moisture resistance

Considerations:

• Slightly higher cost than PU panels

Expanded Polystyrene EPS Core Panels

EPS core panels are a cost-effective insulated metal panel option suitable for projects where budget constraints exist without compromising thermal insulation basic needs. EPS provides a good balance between insulation and affordability, often used in industrial buildings and warehouses.

Key Advantages:

• Affordable with decent thermal insulation
• Resistant to moisture and mold
• Lightweight and easy to handle

Considerations:

• Lower fire resistance compared to PIR and mineral wool
• Slightly less durable under high mechanical stress

Mineral Wool Core Panels

Mineral wool sandwich panels stand out for fireproof performance and sound absorption qualities. The mineral wool core is non-combustible, making these panels perfect for applications requiring high fire safety levels such as factories, shopping malls, and exhibition centers.

Key Advantages:

• Excellent fire resistance (A1 non-combustible rating)
• Superior sound insulation and vapor barrier properties
• High durability and mechanical strength

Considerations:

• Heavier than PU and PIR panels
• Slightly higher cost and more complex installation

Comparing Core Materials Advantages and Disadvantages

Each core material offers distinct benefits in terms of insulation, fire safety, weight, and cost. Choosing the right metal composite panels depends heavily on your specific application, budget, and local building codes in the U.S.

At Shanghe, we provide expert guidance to help you select the best sandwich panel metal cladding options to meet your project’s needs efficiently and reliably.
