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.
