The door and window industry in China has experienced significant growth in recent years, with a wide variety of products competing for market share. Consumers are constantly evaluating the pros and cons of different types of doors and windows. To better understand the current state of the market, Xiao Bian visited companies like Chuanwang Wood and gathered insights from industry insiders.
**Market Share of Aluminum Alloy Doors and Windows**
In China's building door and window market, aluminum alloy doors and windows dominate with a 55% share. Plastic windows follow closely at 35%, while steel windows account for only 6%. Other materials make up the remaining 4%. In terms of production volume, aluminum doors and windows reach approximately 150 million square meters annually. According to the CEO of Chuanwang Wood, this dominance is due to the long-standing development of aluminum products across Chinese cities and towns.
Although aluminum windows have faced criticism in the past regarding quality, they remain a popular choice among many consumers due to economic constraints. Most aluminum windows still use single-pane glass, and those with double-glazed hollow glass account for less than 20% of the market. Despite this, aluminum windows continue to hold a significant portion of the building door and window market.
**The Rise and Challenges of Plastic Windows**
Plastic doors and windows emerged as a new category under national industrial support. After two decades of development, they have become common in households. However, rising raw material costs and some unethical business practices have placed the industry under pressure. Many companies are struggling to maintain profitability and product quality.
**Aluminum vs. Plastic: A Comparative Analysis**
In recent years, consumers have been confused by conflicting information from developers and designers about which type of window—aluminum or plastic—is better. Initially, aluminum windows were praised for their lightweight and attractive design compared to older steel models. However, over time, issues such as poor thermal insulation became apparent, especially in regions with extreme weather conditions.
Later, plastic windows gained popularity and were once considered a must-have for high-end home decoration. But as time passed, challenges arose. With rising material costs, consumer interest waned. Meanwhile, aluminum windows evolved, incorporating thermal break technology and insulating glass, making them more competitive and now associated with premium options.
**Which One Is Better?**
Experts suggest that both aluminum and plastic windows have their own strengths and weaknesses. Neither can be universally preferred. When well-made, both can be excellent choices. According to the CEO of Euro Rain Industry, "Different countries choose different materials based on their economic conditions and lifestyle habits. For example, Italy and Spain use fewer plastic windows, while Germany uses them more frequently. After unification, German residential buildings often use plastic windows, while public buildings tend to go for aluminum."
When it comes to the quality of aluminum windows in China, the person in charge of Ouyu Wood noted, "There is still a big gap between China’s aluminum window manufacturing and global standards. Improvements are needed in hardware components, overall production processes, and installation techniques."
