Core material is a key part of insulation sandwich panels, commonly used include polystyrene, rock wool, polyurethane, etc. These materials have good thermal insulation performance, which can effectively reduce heat transfer and reduce building energy consumption. The use of insulated sandwich panels helps to reduce building energy consumption and carbon emissions, in line with the concepts of green building and sustainable development.

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.
