The five core features of system doors and windows: systematic design, high heat insulation profiles, standard material formulas, high-quality hardware systems, and rigorous production processes.

"System doors and windows": It is a perfect organic combination of performance systems, using system integration thinking, based on the door and window systems developed for different geographical climate environments and functional requirements, various performances such as water tightness and air tightness need to be considered , Wind pressure resistance, heat insulation, sound insulation, heat preservation, anti-theft, operation feel, etc., designed, manufactured and installed in accordance with the overall solution requirements and strict procedures, and finally formed high-performance system doors and windows with high reliability and cost-effective Building doors and windows.

The real energy-saving system doors and windows do not only use heat-insulating broken bridge aluminum profiles or Low-E hollow glass energy-saving materials. It is a perfect combination of the system. The comprehensive results of the performance of each link are indispensable. At present, the most representative brands in the domestic market include: YKK AP, Jiayu, Aluk, Bacoro, Shubiao, Feiyu and other brands.

Convection: The loss of heat is the circulating flow of hot and cold air through the gap between the doors and windows, and the heat is exchanged through the gas convection, resulting in heat loss;
Conduction: Heat conduction is the heat transfer caused by the molecular motion of the material used in doors and windows, which is transferred from one side of the material itself to the other, causing heat loss;
Radiation: Radiation is mainly transmitted directly in the form of rays, leading to loss of energy consumption.

So what is the difference between system doors and windows and ordinary doors and windows?
1. Stability and performance
The system doors and windows have their own independent technical department, which will conduct rigorous tests and inspections on the components of the system doors and windows, so the various components are very well matched and are not prone to failure, which is what we often say is good stability. Ordinary doors and windows are assembled by ordering different parts according to their own needs, but some problems will occur in the process of use, and the stability is relatively poor. After 2 to 3 years of research and development of system doors and windows, the materials, the performance and quality of the entire doors and windows have been comprehensively tested, and the mature products have been launched after reaching the expected goals. Ordinary doors and windows are temporarily integrated door and window products for a single project, and they are often not fully tested.

2. Flexibility
The various parts of the system doors and windows are fixed according to different performances, and the room for selection is relatively small compared with ordinary doors and windows, so the flexibility is small. Ordinary doors and windows can be flexibly configured with their own components according to their needs. The system doors and windows are serialized and standardized products. The slot structure and material supply are highly exclusive and incompatible. The series can only be selected according to the needs of the project. Generally, independent projects will not be developed. Ordinary door and window materials can be selected by domestic and foreign manufacturers, or they can be opened temporarily, which is flexible.
