Exterior wall decorative board is a new building material developed in decoration industry in recent years. The external wall panel is mainly composed of polyester paint or fluorocarbon paint, carved aluminum-zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth. The main functions of external wall panels are architectural decoration, heat preservation and energy saving, heat insulation and sound insulation, waterproof and mildewproof. At present, it is mainly used for exterior wall decoration and energy-saving renovation of gymnasiums, libraries, office buildings, villas and other buildings in schools and hospitals;

Fiber cement external wall hanging board

Fiber cement board has been widely used in external walls abroad, but it is only in recent years in China. Because the fiber cement external wall board is fireproof, anticorrosive, heat-insulating, anti-aging, non-radiation, low cost, energy-saving and environmentally friendly, and simple in construction.

Metal external wall hanging plate

Metal exterior wall hanging panels can also be divided into two categories. One is the composite hanging board, which is mainly composed of three parts. The surface is a high-quality color decorative metal plate with special coating treatment, the middle layer is a hard high-density polyurethane foam heat insulation layer with flame retardant treatment, and the bottom surface is a heat insulation and moisture-proof aluminum foil protective layer.

PVC external wall hanging board

PVC external wall hanging board is a plastic profile with hard PVC as the main body, which is used for the external wall of buildings; Play a role in covering, protecting and decorating. PVC external wall hanging board can also be recycled, and the energy consumption in the manufacturing process is lower than that of cement and tiles, so it is a green building material that is beneficial to environmental protection.

Beautiful decoration

The outer metal panel can be made into artistic appearance such as marble, tile, mosaic and wood grain by embossing and baking, and there are 1 10 colors and textures to choose from.

Heat preservation and energy saving

The thermal insulation material of the inner layer is rigid foamed polyurethane, and the thermal conductivity is less than 0.024 W/m k.

simple structure

The ridge is connected with the wall, and the product does not require high flatness or humidity of the base.

durable

Polyester topcoat is coated on the surface of aluminum-zinc alloy steel plate by baking paint process, and will not fade after outdoor use 10- 15 years. The service life of Al-Zn alloy steel plate is over 45 years.

environmental protection

The materials are environmental-friendly raw materials, assembly lines and finished products, which will not cause harm to the environment during construction and use, and can be recycled.
