2026-01-23 The diverse applications and core advantages of sandwich panels. Sandwich panels are characterized by lightweight, high strength, thermal and sound insulation, modularity, and easy installation. With the flexibility of material combinations, they have been widely and innovatively applied in fields such as construction, transportation, industry, and infrastructure, becoming a key material in modern engineering. 1、 Building field: energy-saving and efficient, suitable for multiple scenes, the exterior wall and roof are suitable for projects such as the reconstruction of old communities. The combination of high-density fiberboard outer layer and polyurethane foam core material can not only reduce the wall load, but also improve the thermal insulation performance and reduce energy consumption; Modular design adapts to the needs of rapid construction and supports sustainable urban renewal. The metal sandwich sandwich panel in refrigerated warehouses and food processing plants can efficientl
