Insulated PU Metal Sandwich Panel
The core insulation performance of the sandwich panel Insulated PU Metal Sandwich Panels offer ultra-low thermal conductivity (≤0.024W/(m·K)), outperforming rock wool (0.040–0.048W/(m·K)) and glass wool (0.035–0.042W/(m·K)). Same thickness blocks heat better,...

The structure and materials of sandwich panels
Composite Structure for Efficient Insulation
Sandwich panels adopt a "metal outer layer + insulation core" design. The outer color steel plate resists wind and rain, reducing external temperature impact; the inner polyurethane (with closed-pore structure) or rock wool blocks heat transfer well. This stabilizes temps in cold storage, factories, and homes, cutting the need for frequent AC or heater use and lowering energy waste.
Thermal Stability & Lower Energy Use
Sandwich panels stand extreme weather-no deformation/failure in summer heat, no cracking in winter cold, keeping insulation consistent. This lowers energy use: winter heating avoids high load, summer AC has fewer starts/stops. They save 15%-20% annual heating/cooling costs vs. traditional brick-concrete buildings, meeting green energy standards.
The production process of sandwich panels
Composite Structure for Efficient Insulation
Design & Components: Adopts "metal outer layer + insulation core" structure. Outer layer uses color steel plate (resists wind/rain, reduces external temperature impact); inner layer uses polyurethane (with closed-pore structure) or rock wool (blocks heat transfer effectively).
Application Effects: Stabilizes indoor temperatures (applicable to cold storage, factories, homes) and reduces frequent use of air conditioners/heaters, lowering energy waste.
Thermal Stability
Weather Resistance: Withstands extreme conditions-no deformation/core failure in summer heat, no cracking in winter cold, and maintains consistent insulation performance.
Lower Energy Use
Energy-Saving & Compliance: Lowers energy consumption (winter heating avoids high load, summer AC has fewer starts/stops), saves 15%-20% annual heating/cooling costs vs. traditional brick-concrete buildings, and meets green energy-saving standards.

Environmental protection and sustainability details of sandwich panels
Material recyclability
Our Insulated PU metal sandwich panel metal panel can be 100% recycled and reused. The polyurethane core material can be degraded into chemical raw materials through professional processes. The material recovery rate throughout the entire life cycle is ≥85%, which is superior to that of glass wool board (the recovery rate is about 60%).
Environmentally friendly production process
Adopting fluorine-free foaming technology (with an ODP value of 0), it avoids the damage to the ozone layer caused by Freon in traditional polyurethane production. The waste gas from the production line is treated by activated carbon adsorption, and the emission concentration is more than 50% lower than the national standard, obtaining the ISO 14001 environmental management system certification.
Health and Safety
The core material does not contain volatile organic compounds such as formaldehyde and benzene (VOC content ≤0.1g/L), and has passed the German GEV EMICODE EC1PLUS certification. It can be directly used in places with extremely high cleanliness requirements such as food workshops and hospital operating rooms.
The application fields of insulation sandwich panels
Architectural Applications
Insulated PU metal sandwich panels insulate buildings' external walls, roofs, floors, and windows. They work with polystyrene/rock wool boards (for walls) and polyurethane/aerated concrete (for roofs) to block heat exchange, cutting heating/cooling energy use.
Industrial Uses
These panels insulate industrial pipelines, equipment, and tanks-reducing heat loss and boosting energy efficiency. They're paired with rock wool casings (for chemical/power pipelines) and aluminosilicate fibers (for high-temperature kilns) to meet industrial needs.
Low-Temperature Logistics
Cold storage, refrigerated trucks, and containers rely on the panels (with polystyrene foam) to keep low temperatures stable. They insulate cold storage walls/roofs and truck bodies, protecting goods from spoilage.
Transportation Applications
Cars, trains, and ships use the panels: in cars (engine/AC systems) to reduce heat transfer; in ships (cabins) for thermal insulation and soundproofing, improving interior comfort.
FAQ
Q: How to solve insulation materials falling off or cracking?
A: • Falling off: Treat the base layer well, use quality adhesives (standard amount), and choose strong insulation materials.
• Cracking: Control insulation layer thickness uniformity, set expansion joints, pick low-shrinkage materials, and do post-maintenance.
Q: Can sandwich panels be indoor partitions?
A: Yes. Lightweight and soundproof, fit for office/warehouse zoning.
Q: Can sandwich panel colors be customized?
A: Yes. Common colors: white, gray, blue. Special colors negotiable.
Q: Can broken sandwich panels be repaired?
A: • Minor scratches: Repaint.
• Small water leakage: Sealant repair.
• Severe damage: Replace the board.
Q: Can PU sandwich panels have both insulation and fire resistance?
A: Yes. Flame-retardant modified (phosphorus-based additives) PU panels reach B1 fire grade, keep low thermal conductivity (≤0.024W/(m·K)), meeting both needs for most industrial/commercial scenes.
Q: Will PU sandwich panels bulge long-term?
A: Quality panels (high-pressure foaming + interface reinforcement) won't bulge easily. Bulging usually comes from poor bonding (insufficient glue) or moisture. Ensure uniform bonding and sealing during installation.
