What is the primary purpose of system windows and doors?
2022-02-02
In residential buildings, system windows and doors are one of the key components—not only serving as air vents but also directly influencing the lighting conditions within the home environment. When many people renovate their windows and doors, due to limited knowledge about window and door products at the initial stage of renovation, numerous defects and mistakes often occur, resulting in installation outcomes that fall short of expectations.
For consumers who need to install system windows and doors, it’s actually important to gain some basic knowledge about window and door installation. This knowledge will help facilitate communication and coordination with the construction workers both before and after the installation of system windows and doors.
The modern architectural doors and windows industry began to develop in the early 1980s and has since undergone nearly 30 years of market evolution and refinement. Yet, ordinary doors and windows with poor performance continue to dominate the Chinese market. China’s door and window technology has been slow to upgrade, making building doors and windows a significant contributor to energy consumption in Chinese buildings. In the future, energy efficiency will see a substantial increase!
As early as the 1980s, Europe had already developed high-performance system windows and doors that far surpass ordinary windows and doors in terms of energy efficiency, safety, and comfort. In 2003, European window and door standards mandated a U-value (K-value) below 1.4, making high-performance system windows and doors even more widespread. Currently, their share in urban construction and market applications has reached 70% of the total window and door volume. In China, the average U-value for windows and doors is around 3.5 (thermal insulation), while Beijing’s current high-standard window and door specifications set the U-value at 1.8. It is estimated that China’s existing urban building area totals approximately 43 billion square meters. If China were to adopt the current European window and door standards—achieving a U-value of 1.4 or lower—annual coal savings could reach 430 million tons of standard coal, roughly equivalent to 20% of China’s annual coal production—a figure that is truly astonishing.
European system doors and windows entered the Chinese market at the end of the 1990s. Currently, the U-value standard for high-performance European system doors and windows can reach as low as 0.8, meaning their energy consumption is roughly only one-quarter of that of China’s building doors and windows.
“Low-carbon” was the central theme of the 2009 Copenhagen World Climate Conference. Countries around the world set targets for energy conservation and emission reduction, and China pledged that by 2020, its carbon dioxide emissions per unit of GDP would be reduced by 40% to 45% compared to 2005 levels. This means that China must adopt concrete energy-saving measures across all sectors of the economy to achieve its target. Currently, building energy consumption accounts for 40% of China’s total societal energy consumption. Window and door systems account for 45% to 50% of building energy consumption, representing 15% to 20% of the nation’s total energy consumption. Clearly, windows and doors are a major source of energy loss in buildings, and replacing them with energy-efficient models will become an inevitable trend.
Therefore, we must enhance the thermal insulation performance of doors and windows from all aspects and encourage people to use high-quality, energy-efficient doors and windows. While China’s door and window technology has yet to reach a high level, Europe’s high-performance system doors and windows have become the benchmark for energy-efficient doors and windows in China!
What is the primary purpose of system windows and doors?
1. Protect residents’ health by creating a healthy and comfortable environment.
2. Protect building structures and decorative elements from the effects of naturally occurring condensation or rainwater in the air. 3. Reduce energy consumption for heating and air conditioning.
4. Reduce maintenance and operating costs.
