High-Density Polyurethane Panels | Industrial cold storage, pharmaceuticals | R-value 6.8/m (ASTM C518), CE-certified, 1.35kW compressor power (IEC 60034) | ▲ Superior thermal efficiency, modular design (container/hinge), energy-efficient | High cost, requires professional installation, flammability risks (ASTM E84) |
Expanded Polystyrene (EPS) Panels | Small cold rooms, temporary storage | Lightweight (20 kg/m³), R-value 4.2/m (ASTM C578), water absorption <0.3% | Cost-effective, easy to cut/install, low moisture absorption | Low durability, poor fire resistance (ASTM E84), compressive strength 200 kPa (ASTM D1621) |
Polyisocyanurate (Polyiso) Panels | Commercial freezers, pharmaceutical cold chains | R-value 8.0/m (ASTM C578), flame retardant (ASTM E84), service temp -40°C to 120°C | ▲ Best thermal performance, fire-resistant, long-term stability | Expensive, requires protective coatings, aging reduces R-value over time (ASTM C1289) |
Fiberglass Insulation Panels | Refrigerated trucks, high-humidity warehouses | R-value 4.3/m (ASTM C578), non-combustible, compressive strength 690 kPa | Fire-resistant, moisture-resistant, rigid structure | Brittle, requires protective layers, heavier than EPS/Polyiso (18–25 kg/m³) |
Aerogel Composite Panels | Ultra-low temp labs, LNG storage | Thermal conductivity 0.02 W/m·K (ASTM C1046), R-value 10/m, lightweight | ▲ Ultra-low heat transfer, lightweight, durable at extreme temps | Extremely costly, fragile, limited availability (ISO 12233) |
Mineral Wool Panels | Dairy processing, meatpacking plants | Density 160 kg/m³, R-value 3.9/m (ASTM C578), acoustic insulation (ISO 10140) | Fire-resistant, sound dampening, eco-friendly (recyclable) | Heavy, prone to settling over time, lower R-value compared to alternatives |
