China Aluminum Network recently introduced insulated aluminum alloy doors and windows, a product that has gained popularity in China after being brought in from abroad. These products are made using heat-insulating aluminum profiles, which are divided into two main types: strip-type and plastic injection type. Currently, over 80% of the insulated aluminum doors and windows available on the market use the strip-type insulation method, making it the most widely adopted solution today.
The strip-type heat-insulating aluminum profile works by splitting a traditional one-piece aluminum frame into two parts, then connecting them with low thermal conductivity insulation strips through mechanical means. This design effectively reduces heat transfer, addressing a common issue with conventional aluminum windows. This technology has been in use in Europe for over three decades, with extensive experience in material selection, structural design, stress control, connection methods, and sealing techniques. As a result, European countries have developed comprehensive technical standards for these products.
In line with these international practices, China has also established its own national technical standards for heat-insulating aluminum profiles. However, despite these efforts, there are still significant issues in both the production and application of aluminum doors and windows in China. Market feedback frequently highlights problems with substandard products, particularly in terms of the quality of the insulation profiles. This not only creates confusion in the market but also leads to frequent disputes and compromises the overall quality of construction projects, ultimately harming consumer interests.
To address these challenges, it is essential for manufacturers to adhere strictly to quality control measures and ensure compliance with established standards. Consumers should also be more informed about the differences between various types of insulated aluminum products to make better purchasing decisions. With continued improvements in technology and stricter industry oversight, the future of insulated aluminum doors and windows in China looks promising.
Water Purifier Kitchen Faucets
The faucets used in general households are unified, and there is no distinction between drinking water and water. But in some western countries, to provide special water purification pipeline, it is required to have a water purification faucet. There is no difference between the clean faucet and the general faucet, but the raw water is different.
