Curtain wall is the maintenance of the exterior wall of a building, which is not load-bearing and looks like a curtain hanging on it. It is a commonly used lightweight wall in modern large and high-rise buildings. In this issue, we will learn about a type of curtain wall.
Curtain walls can be divided into: building curtain walls, component type building curtain walls, unit type curtain walls, glass curtain walls, stone curtain walls, metal plate curtain walls, all glass curtain walls, point supported glass curtain walls, etc. Metal plate curtain walls are further divided into stainless steel curtain walls, aluminum-plastic panel curtain walls, aluminum single panel curtain walls, etc.
In this issue, we are learning about aluminum veneer curtain walls and aluminum veneer flake curtain walls.

Product specifications and classification
Classification
Aluminum veneer curtain wall is a curtain wall made of aluminum panels. The structure of aluminum veneer mainly consists of panel, reinforcement ribs, hanging ears and other components, and insulation mineral wool can also be added to the back of the panel.
The thickness of aluminum veneer mainly uses 1.5mm, 2.0mm, 2.5mm, and 3.0mm sheets. The cost of aluminum sheets with a thickness less than or greater than this has increased on a normal cost basis. The thickness of aluminum curtain wall panels mainly uses 2.0mm, 2.5mm, and 3.0mm panels, and there are 4.0mm and 5.0mm thick aluminum panels available on the market.
Due to the high plasticity of aluminum veneer, aluminum veneer curtain walls are mainly used for the interior and exterior decoration of some large shopping malls, the decoration of lobby facades and columns of various large hotels, elevated corridors, pedestrian bridges, elevator edging, balcony packaging, advertising signs, indoor irregular suspended ceilings, and other decoration.

Material characteristics
Performance
1. High plasticity, due to the relatively low hardness of aluminum, it has good metal ductility and can be shaped into different shapes at will. Moreover, the production and production of aluminum veneer for curtain walls are simple, and the installation steps are simple.
2. It has corrosion resistance, weather resistance, and can effectively resist ultraviolet rays. It is not afraid of wind and sun exposure. Aluminum veneers treated with fluorocarbon paint can maintain color fastness for up to 25 years.
3. Green and environmentally friendly, aluminum veneer curtain wall panels are recyclable and reusable products that are beneficial to the environment. They are energy-saving and environmentally friendly decorative materials advocated by the country.
4. Lightweight, only one-fifth that of marble and one-third that of glass curtain walls, it significantly reduces the load on the building structure and foundation, and has low maintenance costs and high cost-effectiveness.
5. Good insulation and fire resistance, aluminum veneer curtain wall can meet the needs of sound insulation and insulation by punching holes and adding suction cotton; Aluminum veneer curtain wall is made of metal material and is one of the natural fire resistant building materials. After testing, the fire resistance rating of aluminum panel is as high as A2 level, and the melting point is as high as 660 degrees, making it one of the excellent fire resistant building materials.
6. The sound insulation effect is good. After testing, the sound insulation of aluminum veneer products can reach up to 29-32 decibels, which is equivalent to the sound insulation effect of solid brick walls. In infrastructure engineering, it is commonly used as an airport sound barrier, effectively solving the problem of traffic noise
