Differences between system doors and windows and common doors and windows
System doors and windows:
With its own independent technical department, it will conduct strict tests and inspections on all components of system doors and windows. After 2 to 3 years of research and development of system doors and windows, the performance and quality of materials and doors and windows are comprehensively tested, and mature products are launched after reaching the expected goal, so the matching of various components is very good, failure is not easy.
All components of system doors and windows have been fixed according to different performances, and the selection space is relatively small compared with ordinary doors and windows. Therefore, flexible school system doors and windows are serialized and standardized products, with notch structure, material Supply has strong exclusivity and incompatibility, and can only choose series according to the needs of the project. Generally, it will not carry out research and development on individual projects.

ordinary doors and windows:
It is to order different parts for assembly according to their own needs, but there will be some problems in the process of using, and the stability is relatively poor. Ordinary doors and windows are temporary integrated doors and windows products for a single project, which are often not fully tested.
Ordinary doors and windows can flexibly configure their own components according to their own needs. Common door and window materials can be selected by domestic and foreign manufacturers, or temporary mold opening, with strong flexibility.

precautions for purchasing doors and windows
1. Check whether the materials of doors and windows are green and environmentally friendly
Because the materials of doors and windows themselves cannot have radiation, they also need to effectively block ultraviolet rays. While too much sunlight brings natural light to people through the windows, human body is exposed to too much ultraviolet radiation, which will damage health to some extent. Therefore, it is very important whether the door and window materials are green and environmentally friendly.
2. Check whether the quality of doors and windows is excellent
Customary quality good doors and windows are more guaranteed in sound insulation effect, sealing performance, flame retardant and other aspects, and the service life is longer than that of ordinary doors and windows.
When choosing plastic steel doors and windows, it is necessary to understand the characteristics of profiles. Generally, high-grade profiles with bright and clean surface and green white surface are used. Because the formula contains anti-aging and anti-ultraviolet additives, therefore, even if the climate condition is poor, it can ensure that there is no aging and deformation in three to five years.

3. Look at the quality and installation process of door and window accessories
In addition to the materials and manufacturing quality of doors and windows, attention should also be paid to whether the quality of hardware and sealing strips selected for doors and windows is excellent, and how the assembly quality of doors and windows is, because these all directly affect the service life of doors and windows.
4. Door and window purchase should be coordinated with home decoration style
If the doors and windows are not in harmony with the style of home decoration, it will be very abrupt. When the living environment is warm, the relative door can choose warm color system; When the living environment is cold color, the relative door should choose lighter color.
In addition, doors and windows should be closer to the color of the furniture, but there should be a corresponding contrast with the color of the wall. For example, it is better to color wall paint with white wooden doors. Only in this way can the room be layered, not too monotonous, and also make the room feel particularly fresh.

5. The difference between the South and the North should be considered when purchasing doors and windows.
The southern climate is humid and relatively humid, especially in coastal areas, besides wet and cold, there are typhoon and other climate, usually there are many typhoons, with heavy rainfall and very humid. Therefore, doors and windows in the southern region should first be superior to other door and window products in terms of wind pressure resistance and watertightness. At the same time, the southern region is wet and cold, and there is a return to the southern sky. In view of this, it is necessary to ensure that the selected doors and windows have proper thermal insulation performance.
There are obvious changes in the four seasons and many sandstorms in northern China; Considering the characteristics of northern climate, there are some local regulations on the use of doors and windows, such as: the limit for the use of buildings above 7 floors is outwards opening window. The most important thing is that summer is stuffy and winter is cold, so a door and window with good heat insulation effect can bring a lot of comfort to the living room and save a lot of energy consumption. In addition, according to the survey, the indoor temperature of the rooms using plastic steel doors and windows in the North is Ke Gao 4-5 degrees in winter than that using wooden doors and windows; The effect of using double-layer glass in the North is better.
