[China Aluminum Network] In English, the term "window" originated from the ancient Icelandic word vindauga, meaning "wind of the wind." Literal interpretation refers to a wall opening that is covered by a reed or rattan mat. Its more primitive is merely a method of directing light into the room and resisting the harsh climate outdoors. With the rapid development of buildings, doors and windows have entered a new stage where both function and form are important. From the architectural point of view, windows and their regulation of the indoor environment should replace temperature control devices and supporting facilities.
1. Development and application of foreign aluminum alloy doors and windows Aluminum alloy doors and windows began to be applied in advanced industrial countries such as Europe and America as early as the 1930s. After the Second World War, due to the advancement of aluminum industry technology, aluminum doors and windows have been guaranteed by the basic materials, so that aluminum doors and windows have developed rapidly since the 1950s. Aluminum alloys have become a widely used metal material in modern construction industry except for steel with excellent characteristics. Aluminum doors and windows have become the main architectural metal doors and windows.
European and American aluminum alloy doors and windows are mainly used for public buildings. Profiles are mostly made of heat insulating material. Glass is made of hollow glass. Window type is mainly based on airtight type. The market share of aluminum alloy doors and windows in Western Europe is 27%; Northern Europe mainly chooses window types based on insulation and heat insulation; Central Europe considers doors and windows as part of furniture; Southern Europe chooses building functions.
2. Development and application of domestic aluminum alloy doors and windows Aluminum alloy doors and windows are a new generation of metal doors and windows developed in the 1980s after the reform and opening up in the late 1970s in China. They were introduced from Europe, the United States, Japan, and other countries. European heavy-duty windows, Japanese-style and American-style light windows are not suitable for China's national conditions. After more than two decades of development, China's aluminum doors and windows industry has been able and has developed and designed various grades of new products and supporting functional hardware suitable for China's national conditions.
In recent years, the vigorous development of China's construction industry and real estate has provided a huge space for the development of the doors, windows, and curtain walls. It has now become the larger market for doors and windows worldwide. Driven by the strong domestic infrastructure, the aluminum doors and windows industry and the supporting hardware industry have provided a rare opportunity. Due to the late start of aluminum alloy doors and windows industry in China, through the introduction of door and window systems in Europe and the United States and other countries, through the application and learning in recent years, some companies have begun to design their own window and door systems suitable for China's national conditions.
