How to Select the Right 20mm Sandwich Panel for Your Project

Choosing the right 20mm sandwich panel can make a big difference in your build’s performance, cost, and durability. When selecting panels, focus on these key factors to ensure you get exactly what your project needs:

Core Material

• EPS (Expanded Polystyrene): Lightweight and budget-friendly, great for general insulation.
• PET Foam: Offers better fire resistance and moisture control, ideal for harsh or humid environments.
• Rockwool: Excellent fire protection and sound insulation, but heavier and pricier.

Surface Finish

• Consider your exposure environment:
  • Galvanized steel or aluminum facings provide corrosion resistance and are easy to clean, great for outdoor or industrial sites.
  • Stainless steel panels are best when high durability and hygiene are required, such as in food or medical-grade facilities.

Environmental Conditions

• Panels for extreme weather need superior thermal and moisture barriers.
• For moist or coastal areas, prioritize panels with enhanced corrosion-resistant surfaces.

Load-Bearing Requirements

• Ensure the panel provides the right structural rigidity for your application — especially if used for roofing or floor systems like in RVs or cargo trucks.
• Shanghe’s 20mm sandwich panels offer a high strength-to-weight ratio, balancing durability and lightness.

Insulation Performance

• Choose panels with the thermal insulation properties that fit your energy-saving goals. Thicker panels naturally insulate better, but the core material type makes a big impact.

Budget Considerations

• Compare the upfront cost vs. long-term energy savings. Sometimes investing a bit more upfront on better insulation pays off over the life of your building.
• Look for panels that offer quick, modular installation to save on labor costs.
