The requirements of doors and windows in modern residential buildings are higher and higher, and the once neglected corners of doors and windows are getting more and more attention. In spring and summer, due to the influence of wind and sand and the coming of hot weather, consumers' requirements for doors and windows have changed from the most basic ventilation and lighting to the comprehensive requirements of beauty, sealing and opening mode.
In the market, the most popular should be plastic steel doors and windows. Plastic steel doors and windows have many advantages, such as thermal insulation, sealing and sound insulation, corrosion resistance, anti-aging, elegant and beautiful. However, there are many brands and styles of plastic steel windows in the market, and the prices and quality are also very different, which makes it difficult for consumers to distinguish them.
From the present point of view, the doors and windows used by developers in the newly developed commercial houses have been very practical, and the airtightness has reached the residential requirements. However, for the spring, which is most vulnerable to the impact of sand and dust, many consumers expect more functional doors and windows to appear.
All kinds of doors and windows are in the development stage
At present, plastic steel window is the most commonly used product, but its wind sand resistance and water tightness are generally low, the window frame has large shading area, high thermal expansion coefficient, and there are photothermal aging problems.
Wooden window can lead scenery, ventilation, diversion, lighting, heat insulation, sound insulation, heat preservation, and can coordinate the decoration of the interior. It is the banner of creating indoor environment, and is gradually becoming the life trend of high-end doors and windows consumption.
Aluminum alloy doors and windows are developing in the direction of medium and high-grade energy-saving and sound insulation; the traditional solid web and open web steel doors and windows are being phased out because of their poor comprehensive performance. At the same time, people have gradually developed a variety of color plate doors and windows, stainless steel doors and windows and energy-saving color plate doors and windows with heat insulation; the use of high-grade wooden doors and windows and aluminum clad wood doors and windows will increase.
Put forward higher requirements for the function of doors and windows
In terms of function, consumers put forward higher requirements for heat insulation and UV protection of doors and windows. According to statistics, the energy consumption of doors and windows accounts for more than 70% of building energy consumption, and the energy consumption of doors and windows is mainly generated by conduction, radiation and convection, which should be considered from the aspects of frame material, glass and processing accuracy.
Hidden danger: the materials are not complete and the process is different
Uneven materials of aluminum alloy doors and windows: the appearance of aluminum alloy doors and windows is bright and durable. However, with the continuous saturation of market share, the competition between aluminum alloy processing industries is becoming more and more obvious. In order to reduce the cost and gain more market share, some manufacturers have made up their minds on materials and arbitrarily use low-quality materials for combined processing, which eventually leads to the uneven market of aluminum alloy doors and windows.
There are differences in the process of plastic steel doors and windows: the market of plastic steel doors and windows is relatively chaotic, and the prices of the same profiles vary greatly due to different accessories and processing technologies. Regular market, general double glazing casement window, each square meter is about 400 yuan, most of the insulating glass casement window per square meter are more than 1000 yuan. The defects of some poor quality plastic steel doors and windows are obvious: the auxiliary materials such as pressure strip and seal do not match the main profile, the appearance is rough and the sealing performance is poor. If the thickness of steel bracing of poor quality plastic steel doors and windows is not up to standard, even without steel bracing, its service life will be greatly shortened.
Spread: high grade locks are also increasing year by year
The diversification of the door determines that the door lock is bound to become a popular product. Many personalized and decorative door locks have gradually entered the door of consumers. At present, China's door lock market is dominated by mechanical locks. Mechanical locks mainly include spherical locks, handle locks and plug-in locks. The plug-in locks are superior to other locks in terms of anti-theft performance and application scope.
