[China Aluminum Network] The word "window" in English traces its origin back to the ancient Icelandic term "vindauga," meaning "wind hole." Literally, it refers to an opening in a wall covered with reed or bamboo mats. In its most primitive form, it was simply a way to let light into a room and protect against harsh outdoor weather. As buildings evolved rapidly, doors and windows entered a new era where both functionality and aesthetics became equally important. From an architectural perspective, windows and their ability to regulate indoor environments are gradually replacing traditional temperature control systems and auxiliary equipment.
1. Development and Application of Foreign Aluminum Alloy Doors and Windows Aluminum alloy doors and windows were first introduced in advanced industrial countries like Europe and the United States as early as the 1930s. Following World War II, with advancements in aluminum production technology, the material became more accessible and reliable, leading to rapid development of aluminum doors and windows from the 1950s onward. Today, aluminum alloys are among the most widely used materials in modern construction, second only to steel, due to their excellent properties. Aluminum doors and windows have become the dominant type of metal window system in architecture.
European and American aluminum alloy doors and windows are primarily used in public buildings. Their profiles are typically made from insulating materials, and the glass is often double-glazed. The window designs are mostly airtight, focusing on energy efficiency. In Western Europe, aluminum doors and windows account for 27% of the market. Northern Europe prioritizes insulation and heat resistance, while Central Europe treats windows as part of the interior furniture. Southern Europe focuses more on functional building design.
2. Development and Application of Domestic Aluminum Alloy Doors and Windows Aluminum alloy doors and windows emerged in China during the 1980s, following the reform and opening-up policies of the late 1970s. They were imported from Europe, the U.S., and Japan. However, European heavy-duty windows and Japanese or American lightweight styles were not well-suited to China’s climate and building needs. After over two decades of growth, China's aluminum door and window industry has developed and designed various grades of products and hardware tailored to local conditions.
In recent years, the booming construction and real estate sectors in China have created significant opportunities for the doors, windows, and curtain wall industries. China has now become the largest market for doors and windows globally. Driven by strong domestic infrastructure development, the aluminum doors and windows industry, along with its supporting hardware sector, has found a rare growth opportunity. Although the aluminum alloy doors and windows industry started later in China, through the introduction of foreign systems and extensive application and learning in recent years, some companies have begun to develop their own customized window and door systems that better suit China's unique conditions.
