What are Sandwich Panel Walls
Are you looking for a reliable and efficient wall solution for your building projects? Shanghe Sandwich Panel Walls offer a smart answer. These panels are made of two outer metal sheets that sandwich a core insulation layer. This core can be crafted from materials like polyurethane (PUR), polyisocyanurate (PIR), expanded polystyrene (EPS), or mineral wool (rock wool).
The metal sheets provide structural strength and durability, while the insulated core ensures thermal efficiency, fire resistance, and sound control. Together, these components create a lightweight yet solid panel system that is easy to install and maintain.

Technical Specifications of Sandwich Panel Walls
Material Composition and Core Options
Shanghe sandwich panel walls feature high-quality metal outer sheets, typically galvanized steel or aluminum, designed to provide strong structural integrity and excellent corrosion resistance. The core insulation materials vary based on your project needs, including:
- Polyurethane (PUR) – Offers superior thermal insulation with low thermal conductivity.
- Polyisocyanurate (PIR) – Similar to PUR but with enhanced fire resistance.
- Expanded Polystyrene (EPS) – Cost-effective with good insulation properties.
- Mineral Wool (Rock Wool) – Ideal for superior fireproofing and sound insulation.
Each core material is carefully selected to balance insulation, fire safety, and durability.
Panel Thickness Size and Weight
Panels come in a wide range of thicknesses to fit different structural and insulation demands. Typical thicknesses include:
- From 40mm to 150mm or more.
- Standard panel widths usually range around 1,000mm to 1,200mm for easy installation.
- Lengths are customizable to your project specifications.
Weight varies by core and thickness, but overall, these panels remain lightweight yet strong, easing handling and speeding up installation.
Thermal Insulation and Fire Resistance
Our sandwich wall panels deliver excellent thermal insulation with U-values generally between 0.18 to 0.35 W/m²K, depending on core type and thickness. This helps you reduce energy costs and maintain a comfortable indoor environment.
Fire ratings vary by core:
- PIR and Mineral Wool cores achieve high fire resistance ratings, compliant with strict US fire safety standards.
- EPS and PUR cores offer good insulation but lower fire performance; suitable where fire risk is lower or combined with additional protection.
Load-Bearing and Structural Strength
These structural sandwich wall panels are engineered to carry significant loads both vertically and horizontally, making them suitable for industrial, commercial, and residential applications. Their strong metal facings and rigid core resist deformation while providing wind and impact resistance.
Exterior and Interior Surface Finishes
Finishing options are versatile to meet aesthetic and functional needs:
- Exterior finishes include smooth, embossed, or stucco-textured surfaces with coatings designed to resist UV, moisture, and corrosion.
- Interior surfaces are typically smooth and can be painted or laminated depending on cleanroom or residential requirements.
- Custom colors and finishes are available to match branding or architectural styles.
