pu sandwich wall panel
1. Excellent Thermal Insulation Performance
PU (polyurethane) has one of the lowest thermal conductivity values among insulation materials. This makes PU sandwich wall panels ideal for:
Cold storage buildings
Temperature-controlled facilities
Energy-saving industrial buildings
When combined with a sandwich panel roof, the entire building achieves superior insulation performance.
2. High Strength & Structural Stability
The rigid PU core bonds tightly with metal sheets, forming a strong composite structure that provides:
High compressive strength
Excellent wind resistance
Long-term structural reliability
3. Fast Installation & Reduced Labor Cost
PU sandwich wall panels are pre-fabricated and easy to install, allowing:
Faster construction timelines
Reduced labor requirements
Lower overall project costs
This is especially valuable for large-scale B2B construction projects.
4. Energy Efficiency & Cost Savings
By minimizing heat transfer, PU sandwich wall panels reduce energy consumption for heating and cooling, leading to:
Lower operating costs
Improved building efficiency
Faster ROI for investors
5. Lightweight Design
Compared to traditional concrete or brick walls, PU sandwich wall panels are lightweight, which:
Reduces foundation load
Simplifies transportation
Improves installation efficiency
6. Fire Resistance Options
Depending on project requirements, panels can be customized to meet fire safety standards using PIR or modified PU cores.
7. Corrosion Resistance & Durability
With pre-coated steel or aluminum surfaces, panels offer:
Strong corrosion resistance
Weather resistance
Long service life (20+ years)
8. Flexible Customization for B2B Clients
We support OEM/ODM services:
Panel thickness customization (50mm–200mm)
Surface color (RAL options)
Surface texture (flat, embossed, corrugated)
Length customization
Branding & packaging
Product Details
1. Structure of PU Sandwich Wall Panel
The PU sandwich wall panel consists of three layers:
Outer Layer: Pre-painted galvanized steel (PPGI/PPGL) or aluminum
Core Material: Rigid polyurethane (PU) foam
Inner Layer: Steel sheet or aluminum foil
This structure provides excellent insulation, strength, and durability.
