Curtain advantages in construction:

1, from the heavy resistance to a more lightweight sheet metal and structures (natural stone thickness 25mm, new materials to achieve the thinnest 1mm)
2, fewer species gradually more types of sheet metal and richer color (there are stone, ceramic plates, glass, high pressure laminates, cement fiber wool board, glass, inorganic glass, steel, ceramic plate, ceramic protection plate, a metal plate nearly 60 kinds of sheet metal exterior wall)
3, higher security
4, more flexible and convenient construction technique
5, higher waterproof performance and extend the life of the curtain wall (curtain wall development from closed-end to open-end curtain wall)
6, environmental protection and energy saving (the construction market in Europe and America now more commonly used as a decorative metal insulation board, by a color paint aluminum-zinc alloy carved finish, polyurethane insulation, glass fiber composite made; both decorative and functional thermal insulation, paint 10--15 years without fading, the overall service life of up to 45 years;
