Core Positioning: Beyond Thermal Insulation, Understanding Industrial-Grade Precision Needs
The new generation of PU sandwich panels breaks the single-function limitation of traditional enclosure materials. With "customized formula + precision composite technology" as the core, it creates an integrated enclosure panel suitable for extreme working conditions and high-end scenarios. Composed of imported rigid polyurethane core and high-grade surface panels, the product is formed through multiple precision processes. It not only boasts excellent thermal insulation performance, but also resists complex environmental challenges such as acid-base corrosion, strong wind load, and high-low temperature cycles. Widely used in high-end cold chain, precision manufacturing, data centers, high-end commercial complexes and other fields with strict material performance requirements, it provides a full-chain solution from design, customization to project implementation.
Three Core Technologies for Superior Quality
Imported Fluorine-Free Foaming Technology
Constant Temperature & High Pressure Composite Technology
Panel Precision Coating Technology
Performance Matrix
Five Dimensions Exceeding Industry Standards
Extreme Environment Adaptation
It resists low temperatures down to -50℃ and high temperatures up to 100℃, suitable for long-term use in extreme working conditions such as alpine regions, high-temperature workshops, and cold chain low-temperature warehouses. With a performance attenuation rate of less than 5% per 10 years, it meets the complex needs of multiple regions and scenarios.
Efficient Sound Insulation & Noise Reduction
The porous closed-cell structure of the core and the damping effect of the panel work together, blocking over 50 decibels of medium and high-frequency noise. It effectively reduces noise interference from equipment operation and personnel flow, creating a quiet environment for precision workshops, data centers, and high-end office buildings.
Super Fire-Retardant Performance
Adopting Grade A non-combustible core formula (some models achieve Grade A fire protection), combined with flame-retardant panels and fire-sealing joint design, it releases no toxic smoke during combustion, with a dense and stable carbonized layer that effectively blocks fire spread. It has passed the highest-level fire protection test of GB 8624-2012, suitable for densely populated and high-end industrial scenarios.
Lightweight & High Load-Bearing
With a density of only 55-65 kg/m³, it is 40% lighter than rock wool panels of the same thickness, significantly reducing the load on the main building structure. Boasting a bending capacity of 3000 kN/m², it can be directly used for large-span roofs and walls without additional load-bearing supports, reducing construction costs.
Full-Affect Moisture-Proof & Anti-Seepage
The core material has a hydrophobic rate of 99% and a water absorption rate of ≤0.3 g/100 cm². Combined with special sealant and splicing technology, it effectively blocks moisture penetration, preventing core material from damp aging. It is suitable for humidity-sensitive scenarios such as coastal humid areas, underground buildings, and food workshops.
Customization Services: On-Demand Customization for Precise Scene Adaptation
Relying on flexible production lines and a professional R&D team, we provide full-dimensional customization services, breaking the limitations of standardized products to accurately meet the exclusive needs of projects:
Specification Customization
Supports on-demand cutting of panel thickness (50-300mm), width (900-1200mm), and length (up to 15m), adaptable to special structural designs such as irregular roofs and curved walls.
Performance Customization
Optimizes formulas for different scenarios, such as high-insulation type for cold chain (thermal conductivity ≤0.017 W/(m·K)), strong anti-corrosion type for chemical industry, and sound-insulation type for data centers, accurately matching core scenario needs.
Panel Customization
Panel materials can be galvanized steel, color-coated steel, or aluminum-magnesium-manganese alloy. Coating colors support full-color customization from the RAL color card, balancing practicality and architectural aesthetics.
Joint Customization
Provides exclusive joint design services, customizing supporting seals and fasteners for key parts such as roof corners, wall joints, and door/window openings to enhance the sealing and stability of the entire system.

Frequently Asked Questions
What is the production cycle for customized PU sandwich panels?
+
-
The production cycle for conventional customized specifications is 7-10 working days. For special performance, irregular specifications or large-batch orders, the production cycle can be adjusted according to actual conditions, and the technical team will follow up the whole process to ensure on-time delivery.
Is additional waterproofing required after installing PU sandwich panels?
+
-
In conventional scenarios, good waterproof effect can be achieved with our customized seals and splicing technology, no additional treatment is needed. For scenarios with extremely high waterproof requirements such as roofs and coastal humid areas, supporting waterproof upgrade solutions can be provided to further improve waterproof performance.
How to select the thickness and performance parameters of PU sandwich panels for different scenarios?
+
-
We will accurately match parameters for customers based on scenario type, climate conditions, usage needs and other factors. For example, 20mm thickness and high-insulation formula are recommended for cold chain cold storage; 16mm thickness and sound-insulation formula are recommended for precision workshops.
How does the long-term maintenance cost of PU sandwich panels compare with other sandwich panels?
+
-
PU sandwich panels have a long service life and stable performance, requiring almost no special maintenance in the later stage. Only regular inspection of whether the seals at the joints are aging is needed. The maintenance cost is more than 60% lower than that of rock wool panels and EPS sandwich panels, with higher cost performance for long-term use.
Do you provide construction guidance and installation team services?
+
-
We provide free construction technical guidance to assist the construction team in mastering installation points and joint handling skills. At the same time, according to customer needs, we can recommend cooperative professional installation teams to ensure installation quality and efficiency, realizing rapid project implementation.
