In the past two years, many things called system doors and windows have appeared in the market? What are these doors and windows? The surface looks no different from ordinary ones. Why are system doors and windows much more expensive than broken bridge aluminum? Where is system doors and windows better?

In the past two years, many merchants who used to sell ordinary products in the market have changed their facade signs and marked them. Is it really a product upgrade? The answer is not bad. The reason is that there are too many ordinary people in the market. Everyone is the same. It is nothing more than different brands. Naturally, there is no selling point of products and their own advantages, therefore, they all fought a price war, making the profits of doors and windows lower and lower. At this moment, some merchants changed their names to system doors and windows. Is that really just the ordinary broken bridge aluminum changed their names?

System doors and windows are more or less different from ordinary ones, but the essence is still, what is system doors and windows? What is the difference between them?

System doors and windows are a perfect organic combination of performance systems. Water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, A series of important functions such as operating hand feeling should also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose and seals, which are indispensable to form high-performance system doors and windows. System doors and windows are engineering concepts, not product concepts. Strictly speaking, not all broken bridge aluminum windows in the market can be called system doors and windows.

What is the difference between system doors and windows and ordinary ones?

1. The manufacturing process is different: it is generally a mechanical corner set without glue injection; The middle end connection is fixed by screws; While the system doors and windows are treated with glue injection at the mechanical corner set; secondly, pin is used for the middle-end connection, and screws cannot be seen on the outer surface of the window. The manufacturing process of system doors and windows is better than that of ordinary broken bridge aluminum windows.

2. Different installation processes: generally, neutral silicone rubber weathering glue is used for sealing during installation, while the system doors and windows adopt the on-site installation method of adhesive strips, that is, after the glass is installed, press another sealing strip on the glass frame, or use silicon sealant. Both installation processes are OK, but system doors and windows are more concerned with window isobaric, and more attention is paid to balancing indoor and outdoor pressure in design.

3. Different glass requirements: tempered glass must be used for system doors and windows, while ordinary tempered glass or ordinary glass can be used. It is recommended to use three glasses and two chambers of Low-E glass for system doors and windows, this kind of system doors and windows can reflect its real energy saving and consumption reduction.

4. Different shipments: for example, it is also produced by two people, and can be shipped 30 square meters per day, while it may take 2 days to produce 30 square meters of system doors and windows, and the system doors and windows are slow-working, therefore, the labor cost of system doors and windows is higher than that of ordinary broken bridge aluminum windows. System doors and windows are a tedious production process, which is more rigorous in production and processing.

Therefore, system doors and windows are upgraded products in common production technology, with finer workmanship and more firm and reliable. System doors and windows comprehensively consider sound insulation, heat preservation and sealing, energy saving and consumption reduction.

To sum up, it is an upgrade product of ordinary broken bridge aluminum windows in process and installation. System doors and windows consider all factors comprehensively, which is a real energy-saving door and window product, at present, the market price of system doors and windows ranges from 1200 to 3,000 yuan per square meter, while the market price of imported brand system doors and windows ranges from 3,000 to 5,000 yuan per square meter.
