Sandwhich panels are prefabricated structural panels composed of
“Rigid PUR/PIR cores provide superior thermal insulation with minimal material thickness, leading to space and energy efficiency.” — European Rigid Foam Insulation Industry Report (2019)
“Polyurethane sandwich panels show a high strength-to-weight ratio and maintain insulation performance under dynamic loading.” — Materials Journal, Peer-Reviewed Study (2023)
“A breakthrough product reshaping energy-efficient industrial architecture worldwide.” — Asia Construction Materials Association (2024)
These independent reports validate polyurethane sandwich panels as a proven, research-backed material for sustainable and high-performance construction.
✅ Lightweight ✅ Strong ✅ Cost-efficient ✅ Modern appearance
| Feature | Description |
|---|---|
| Thermal Insulation | Ultra-low thermal conductivity (≤ 0.024 W/(m·K)) for energy-efficient envelopes in cold rooms and warehouses. |
| Fire-Rated Core | PU / PIR cores available in B-s2,d0 and higher grades; certified for industrial wall and roof applications. |
| Lightweight Construction | Up to 70% lighter than brick or concrete walls, reducing steel frame load and foundation cost. |
| Quick Installation | A polyurethane sandwich panel wall system can be installed 70% faster than masonry, lowering installation cost per m². |
| Durability | Metal skins with corrosion-resistant coatings ensure 20–35+ years of reliable service life. |
| Eco-Friendly Foam | CFC-free, low-VOC polyurethane foams contribute to green-building credits (LEED / BREEAM). |
“Endorsed by leading building material associations for energy efficiency, fire safety, and sustainability in polyurethane sandwich panel systems.”
| Model | Core Material | Application | Price (FOB) | MOQ |
|---|---|---|---|---|
| SP-50 PU | Polyurethane (PU) | Warehouses / Workshops | US$ 7 – 9/㎡ | 200 ㎡ |
| SP-75 PIR | Polyisocyanurate (PIR) | Showrooms / Commercial Walls | US$ 9 – 11 /㎡ | 200 ㎡ |
| SP-100 RW | Rock Wool | Fire-Proof Projects | US$ 8 – 10 /㎡ | 150 ㎡ |
| SP-150 PU | PU | Cold Storage Rooms | Custom Quote | 120 ㎡ |
“For polyurethane sandwich panel cold storage or ultra-low U-value applications, thicker PU cores (100 – 200 mm) are recommended..”
A comparative analysis published in Journal of Building Science (2022) concludes that polyurethane panels can achieve equal or better insulation at half the thickness of rock wool panels, while reducing wall weight by over 40%.
Polyurethane sandwich panel vs rock wool panel studies consistently show improved thermal efficiency, lower installation cost per m², and enhanced moisture resistance for PU systems.
