Sandwich panels have excellent sound insulation effects. The density and structure of the core material can effectively absorb and reduce the transmission of sound, providing residents with a quiet and comfortable living environment. Sandwich panels also have high fire resistance performance. Some core materials such as rock wool have good fire resistance, which can effectively prevent the spread of fire and improve the safety of buildings.

Sandwich panels typically consist of two layers of metal sheets (such as steel plates, aluminum plates, etc.) and one layer of core material, which can be materials such as polystyrene, rock wool, polyurethane, etc. This sandwich structure allows the sandwich panel to have both the strength and rigidity of a metal plate, as well as the insulation, sound insulation, fire resistance, and other properties of the core material.
