The Science of Composite Sandwich Panels

Delivering Thermal Efficiency and Structural Integrity through Information Gain

🔬

PIR vs. PUR Core Technology

Our panels utilize high-density Polyisocyanurate (PIR) and Polyurethane (PUR). PIR offers superior fire resistance (B1 grade) and thermal stability, making it the industry standard for high-safety cold storage environments.

🔒

Precision Cam-Lock Systems

Engineered for modularity, our cam-lock panels ensure an airtight seal. This structural design minimizes thermal bridging, reducing energy costs for refrigerated facilities by up to 30% compared to traditional building methods.

🛡️

Fire Compliance & Safety

Safety is non-negotiable. Our panels are tested for smoke density and flame spread, meeting stringent international standards for industrial construction and chemical storage facilities.

Why Composite Panels?

Composite sandwich panels are not just "walls"; they are sophisticated thermal envelopes. In the modern cold chain, where temperature fluctuations can lead to massive losses in the pharmaceutical or food sectors, the thermal conductivity (λ-value) of your panels is the single most important factor for ROI. Shaanxi YSHT panels offer a λ-value as low as 0.019 W/m·K.

Frequently Asked Questions

What is the difference between PIR and PUR panels?
While both are polyurethane-based, PIR (Polyisocyanurate) has a higher chemical stability and significantly better fire resistance. PIR panels are often required by insurance companies and fire safety regulations in large industrial projects.
How long do composite sandwich panels last?
When properly installed and maintained, high-quality composite panels from Shaanxi YSHT can last over 25-30 years without losing significant thermal efficiency.
Do you provide international installation support?
Yes, we provide comprehensive project design and construction guidance. For large international projects, we offer technical consultation to ensure the panels and refrigeration units are installed to peak performance standards.
What is the typical lead time for a global order?
Lead times vary by order size, but thanks to our two automatic production lines, we typically dispatch standard orders within 15-25 days.
