Picking the ideal core for sandwich panel systems is essential to ensuring the final product meets performance requirements while remaining cost effective and lightweight. Laminated panel systems consist of paired rigid facings bonded to a robust yet weight-optimized interior core, and the core serves as the foundation in determining rigidity, thermal performance, mass, and longevity.

Polyurethane cores are widely adopted in industrial and HVAC applications due to their superior heat resistance and secure lamination properties. They offer robust load-bearing capacity and are typically deployed where thermal performance is critical. However, they can be vulnerable to thermal degradation and may emit toxic gases during combustion unless inhibited with fire-suppressing additives.

Polystyrene, available in expanded or extruded forms is commonly utilized because it is inexpensive, easy to fabricate, and provides good moisture resistance. It is often chosen for short-term installations but lacks the thermal performance and fire resistance of polyurethane. XPS has enhanced strength and rigidity than EPS, making it a preferred option for high-stress environments.

Honeycomb structures, typically made from metallic, paper-based, or polymer substrates, offer outstanding stiffness per unit mass. They are ideal for aerospace, transportation, کانکس ساندویچ پانل and high performance industrial uses because they provide rigidity without adding much mass. However, they are cost-prohibitive and require precision fabrication methods. Their porous design also means they may need secondary barriers against humidity and heat transfer.

Fibrous mineral insulation cores stand out for their non-combustible nature and noise-reducing properties. Often used in offices, hospitals, and manufacturing plants, they meet stringent fire safety codes and resist collapse in extreme temperatures. While they are bulkier compared to EPS or PUR and offer diminished heat resistance per unit depth, they are indispensable in applications where fire protection and noise control are critical.

When selecting a core, consider the operating conditions and climate, the mechanical load expectations, energy efficiency and noise reduction goals, fire safety regulations, and financial limitations. For example, a logistics facility facade may benefit from affordable foam cores, while an aircraft interior would require the high strength and lightness of a honeycomb core. Conducting field trials and environmental simulations and seeking expert advice from specialists can help eliminate premature system degradation. The right core material doesn’t just boost functionality—it can significantly prolong structural durability.
