Great Wall Texture PU Sandwich Panel

Metal surface insulation pu foam wall decorative panel great wall type

Rich selection of textures and colors meet different decoration requirements, giving the city and the buildings a new look.
The PU foam is the most advanced and eco-friendly insulation material in the world. With the help of the back aluminum foil, the thermal preservation effect achieves the best.
The unique structure prevents the heat loss in winter. Meanwhile it reduces the heat of the summer sunshine.
Aceta paintcoat and flurocarbon paint of weather resistance performance are applied on surface of wall panel. It is reserved with superior self-cleaning, weather resistance, corrosion resistance and acid& alkali resistance performance.
Light weight with 3.7Kgs/m2 makes the installation easy.
The installation process is clean and tidy without any noise and dust, construction waste.
Different selections of accessories meet different effects.
High quality and stable performance: Manufactured in CNC automation production line, the product pass rate can reach 99.9% with stable chemical structure and physical structure.
