1. From bulkiness to lighter plates and structures (the thickness of natural stone is 25mm, and the thinnest new material is 1mm).
2. Gradually move towards more types of plates and richer colors (currently there are stone, ceramic plate, glass-ceramic, high-pressure laminate, cement fiber silk board, glass, inorganic glass fiber reinforced plastic, clay plate, ceramic plate, metal plate, etc.) Nearly 60 kinds of panels are used in exterior walls).
3. Higher security performance.
4. More flexible and convenient construction technology.
5. Higher waterproof performance prolongs the life of the curtain wall (from closed curtain wall to open curtain wall).
6. Environmental protection and energy saving (the metal decorative thermal insulation board is more commonly used in European and American construction markets today, which is composed of aluminum-zinc alloy carved veneer, polyurethane thermal insulation layer, and glass fiber cloth that have undergone color baking paint; both decoration, thermal insulation and energy saving functions are considered. 10-15 years without fading, the overall service life can reach 45 years).
