PIR/PU Sandwich Cold Room Panel
PIR/PU sandwich cold storage panels are highly efficient insulation building materials specially developed for low-temperature storage environments such as cold storage rooms, refrigeration rooms, and quick-freezing workshops. They are composed of PIR (polyisocyanurate) or PU (polyurethane) as the core insulation material, with metal panels (color steel plates, galvanized steel plates, stainless steel plates, etc.) composite on both sides, and are formed through professional composite processes It features excellent thermal insulation performance, structural stability and weather resistance, and is a core enclosure material in modern cold chain logistics, food processing, pharmaceutical storage and other fields.

Q1：High-Efficiency Thermal Insulation: Reducing Cold Storage Operating Costs at the Source
A: Exceptional Thermal Resistance, Drastically Reduced Energy Consumption:
Achieves a 15%-20% reduction in refrigeration energy use for cold storage facilities of comparable scale.
Moisture-Resistant & Non-Absorbent, Durable Insulation:
Performs reliably in high-humidity environments (e.g., seafood, fresh produce), preventing insulation degradation from water absorption. Ensures stable temperature control, meeting the stringent requirements of the food and pharmaceutical industries.
Q2: Structural Stability: Ensures Long-Term, Safe Operation
A: High Strength & Load-Bearing Capacity:
Withstands additional loads from overhead fixtures and piping. Resists warping or cracking even in extreme temperatures (-50°C to 120°C), preventing coolant leaks and safety hazards.
Corrosion-Resistant & Long-Lasting:
Features metal panels (hot-dip galvanized steel or 304 stainless steel) with weather-resistant coatings, resisting condensation corrosion and oxidation. Offers a service life of ≥15 years, 5-7 years longer than standard color-coated sandwich panels.
Q3: Flexible Adaptation: Lowers Construction & Time Costs
A: Fully Customizable Dimensions, Minimal Waste:
Available in thicknesses (50-200mm), widths (800-1200mm), and lengths (up to 18,000mm) to fit projects from commercial freezers to large industrial cold storage. Reduces on-site cutting waste, increasing material utilization to over 95%.
Quick Installation & Excellent Sealing, Doubled Efficiency:
With joint gaps ≤0.5mm, requires minimal caulking. Cuts installation time for a 1000㎡ cold storage by 30% compared to standard panels, reducing labor costs and future maintenance.
