Hollowpanel

Hollowpanel is a class of lightweight panels that incorporates a hollow interior, typically created by bonding two outer skins to a lightweight core. The hollow core reduces weight and can improve thermal and acoustic performance, depending on the core design and materials. Hollowpanel systems are used in architecture, interior finishing, furniture, and some transportation applications as versatile panels for walls, doors, partitions, and cladding.

Construction and materials: common configurations include sandwich panels with metal, wood, or composite facings and a core made of foam, paper honeycomb, or corrugated material. The core may be a closed-cell foam for insulation or a lattice/honeycomb structure for stiffness. Panels are usually manufactured by bonding or laminating the skins to the core, sometimes with adhesive layers, edge seals, and additional surface finishes. The choice of skin and core material influences fire resistance, moisture tolerance, and mechanical performance.

Applications: hollowpanel appears as interior partitions, door panels, wall and ceiling cladding, display panels, and lightweight furniture components. In some sectors such as aerospace and automotive interiors, hollowpanels help reduce overall weight while maintaining structural integrity.

Advantages and limitations: key benefits include weight reduction, potential for improved thermal and acoustic performance, ease of handling, and customization in thickness and finish. Limitations include lower load-bearing capacity than solid panels of equal thickness, potential moisture sensitivity depending on the core, and more complex repair or replacement. Cost varies with core material, skin, and manufacturing method.
