1. Superior Insulation Performance
Our PU sandwich wall panels use high-density polyurethane foam (38–42 kg/m³) to reduce heat transfer, cut energy costs, and stabilize indoor temperatures across hot and cold climates.
2. Lightweight but High Structural Strength
Thanks to a rigid PU foam core combined with steel/Alu-zinc surfaces, the panels offer strong compressive strength while remaining lighter than traditional metal or concrete wall systems—easy for one-person handling.
3. Excellent Fire & Moisture Resistance
Closed-cell PU core provides low water absorption, preventing mold and humidity issues in coastal or tropical regions. Optional fire-rated PU/PIR cores available for building code compliance.
4. Quick Installation & Labor Savings
Interlocking tongue-and-groove design allows fast assembly on modular houses, prefab buildings, warehouses, and cold rooms. Cuts installation time by 40–60%.
5. Long Service Life & Low Maintenance
Anti-corrosion coated steel sheets (PPGI / PPGL) protect against rust, salt, UV, and chemical exposure—ideal for industrial, commercial, and residential applications.
6. Customizable Options for Any Project
Choose thickness (40–200 mm), colors, steel surface types, and core materials (PU / PIR). Compatible with container houses, expandable houses, prefab kits, and controlled-environment rooms.
PU sandwich wall panels are suitable for a wide range of uses:
- Prefab modular houses
- Expandable container houses
- Residential and commercial wall systems
- Cold rooms and freezer rooms
- Factories and warehouses
- Offices, schools, clinics
- Portable cabins and temporary housing
