It not only has excellent thermal insulation performance, but also has good frost resistance and sound absorption. The second thermal insulation layer 52 is an XPS thermal insulation board layer. XPS has a closed-cell honeycomb structure. This structure allows the XPS board to have extremely low water absorption, low thermal conductivity, high compressive resistance, and anti-aging.
