Cladding panel wall panel have three core technologies, as follows,

The panel`s top layer is Aluminum-zinc coated metal board. The paint on the top layer is PVDF print or weather-resistant enamel polyester paint, which integrates self-cleaning, weather-resistant, etch-proof and Acid&Alkali-proof together.

The core material--hard polyurethane foaming is the most advanced and eco-friendly heat-insulation material. This effect of heat-insulation will decrease less than 3% after this material is used under high temperature for 25 years, at the same time, this material is combined with glass fiber paper on the back, which guranteed Hanyi sandwich panel sysrem in a stable and perfect effect of heat-insulation.

The last layer glass fiber paper can adjust the humidity of the wall, which avoided the humidity and mildew of inside the room.
