Key Factors to Consider When Choosing Sandwich Panels for Warehouses.

Selecting the right sandwich panels for your warehouse is crucial for ensuring energy efficiency, durability, and operational performance. These panels, composed of an insulated core between two metal facings, play a vital role in temperature control, structural integrity, and long-term cost savings. However, not all sandwich panels are created equal. Making the wrong choice can lead to increased energy costs, maintenance issues, and even safety hazards.

At Shenyang Zishenlong Light Steel Color Plate Co., Ltd., we help clients worldwide choose the perfect sandwich panels for their warehouse needs. This guide covers the essential factors to consider when selecting sandwich panels for warehouses.

1. Thermal Performance and Insulation

① Core Material Options

• PIR/PUR Foam: Offers the highest thermal resistance (λ-value: 0.022–0.028 W/m·K). Ideal for temperature-controlled warehouses.

• Rock Wool: Provides fire resistance and sound insulation but has a lower R-value (λ: 0.035–0.042 W/m·K).

• EPS (Expanded Polystyrene): A budget-friendly option with moderate insulation (λ: 0.033–0.038 W/m·K).

② Climate Considerations

• Cold Climates: Thicker panels (100–200mm) with PIR cores to prevent heat loss.

• Hot Climates: Reflective metal facings to reduce solar heat gain.

2. Fire Safety and Compliance

① Fire Rating

• Class A (Non-Combustible): Rock wool cores are ideal for high-risk storage (e.g., chemicals, flammable goods).

• Class B/C (Limited Combustibility): PIR/PUR panels with flame-retardant additives.

② Regulatory Standards

• Ensure compliance with local building codes (e.g., EN 13501-1 in Europe, NFPA in the U.S.).

• Look for certifications like FM Approval or CE marking.

3. Durability and Environmental Resistance

① Facing Materials

• Galvanized Steel: Cost-effective and durable for most environments.

• Aluminum Zinc Coated Steel: Superior corrosion resistance for coastal or humid areas.

• Stainless Steel: For highly corrosive environments (e.g., chemical storage).

② Protective Coatings

• PVDF/Polyester Coatings: Resistant to UV rays, scratches, and fading.

• PE Coatings: Budget-friendly but less durable.

4. Load-Bearing Capacity

① Roof vs. Wall Panels

• Roof Panels: Must support snow loads, wind uplift, and maintenance personnel.

• Wall Panels: Designed for wind pressure and impact resistance.

② Span Capabilities

• Longer spans require thicker panels or reinforced cores.

6. Installation and Maintenance

① Ease of Installation

• Lightweight Panels: Reduce labor time and structural support needs.

• Integrated Joint Systems: Ensure airtight seals and quick assembly.

② Maintenance Requirements

• Smooth Surfaces: Easy to clean and less prone to dust accumulation.

• Corrosion-Resistant Materials: Minimize long-term upkeep.

---

7. Sustainability

① Recyclability

• Steel Facings: 100% recyclable at end-of-life.

• Eco-Friendly Cores: PIR and rock wool can be repurposed.

② Energy Efficiency

• Proper insulation reduces HVAC costs and carbon footprint.

8. Checklist for Selecting Sandwich Panels

• Determine insulation needs based on climate and stored goods.

• Verify fire safety ratings for your industry.

• Choose facing materials suited to your environment.

• Calculate load requirements for roofs and walls.

• Compare lifecycle costs, not just initial price.

• Ensure regulatory compliance for your region.
