In the field of doors and windows, there has been no strict industry definition of the two terms system doors and windows and door and window system. In the eyes of ordinary people, a door and window with slightly better materials is a system door and window. In the eyes of some door and window shops or designers, as long as the designed doors and windows are system doors and windows.
Today, let's boldly analyze and define the concepts of "system door and window" and "door and window system".
The system is a combination of several components that interact and depend on each other. It is an organic whole with specific functions, and this organic whole is a component of the larger system to which it belongs. -Qian Xuesen
It is not difficult to see from Qian lao's words that the system is a huge and organic whole. it is not impossible without one of them, but it is not so perfect without a part.
System doors and windows
The system door and window is a perfect organic combination of the performance system, which needs to consider a series of important functions such as water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, theft prevention, sunshade, weather resistance, operating hand feeling, etc., and also needs to consider the comprehensive results of the performance of each link of equipment, profiles, accessories, glass, glue and seals, which are indispensable to form a high-performance system door and window. -Baidu Encyclopedia
In fact, to put it bluntly, system doors and windows are the doors and windows finally produced through system design, processing, production, testing, etc.
Door and window system
The door and window system is not only made of materials, but also needs technical support and after-sales service. One-stop service doors and windows can truly become system doors and windows. -Baidu Encyclopedia
In fact, the door and window system is a large whole, and the doors and windows of the system are only products in this large whole. No matter design, production, sales, after-sales and many other links are all part of this door and window system.
