1. The difference between system doors and windows and ordinary doors and windows

System doors and windows:

It has its own independent technical department, which will conduct strict testing and inspection on each component of the system doors and windows. After 2 to 3 years of research and development of system doors and windows, the materials, performance and quality of the entire doors and windows are comprehensively tested. After reaching the expected goals, mature products are launched. Therefore, the various components are well matched and are not prone to failure.

Each component of system doors and windows has been fixed according to different performances. Compared with ordinary doors and windows, the room for selection is smaller, so the flexibility is less. System doors and windows are serialized and standardized products. The slot structure and material supply are highly exclusive and incompatible. Series can only be selected according to the needs of the project, and individual projects are generally not developed.

Ordinary doors and windows:

Just order according to your own needs.It is assembled with the same parts, but some problems may occur during use, and the stability is relatively poor. Ordinary doors and windows are door and window products that are temporarily integrated for a single project and are often not fully tested.

Ordinary doors and windows can flexibly configure their own components according to their own needs. Ordinary door and window materials can be selected from domestic and foreign manufacturers, and molds can also be made temporarily, which is highly flexible.

2. Things to note when 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 emit radiation and must be able to effectively block ultraviolet rays. While too much sunlight brings natural light to people through windows, the human body is exposed to too much ultraviolet rays, which will damage health to a certain extent. Therefore, it is very important whether the door and window materials are green and environmentally friendly.

2) Check whether the doors and windows are of good quality

Generally, doors and windows of good quality have good sound insulation effect and Sealing, flame retardancy and other aspects are more guaranteed, and the service life is longer than ordinary doors and windows.

When choosing plastic steel doors and windows, you need to understand the characteristics of the profiles. Generally, those with smooth surfaces and white and bluish colors are high-end profiles, because their formulas contain anti-aging, Anti-ultraviolet additive, so even if the weather conditions are poor, it can be guaranteed not to age and deform for 30 to 50 years.

3) Look at the quality and installation process of door and window accessories

In addition to the materials and production quality of doors and windows, etc. In addition to the above aspects, you should also pay attention to the quality of the hardware and sealing strips selected for the doors and windows, as well as the assembly quality of the doors and windows, because these directly affect the service life of the doors and windows.

4) The purchase of doors and windows should be based on home decoration Style Coordination

If the doors and windows are not coordinated with the home decoration style, it will look very abrupt. When the living environment is in warm colors, the opposite door can be chosen in warm colors; when the living environment is in cool colors, Instead, choose a lighter color door

In addition, the color of doors and windows should be close to the color of the furniture, but should be in contrast with the color of the wall. For example, it is best to use white wooden doors to make the wall paint colorful. It has a sense of hierarchy, is not too monotonous, and makes the room feel particularly fresh.

5) When purchasing doors and windows, consider the differences between the north and the south

The southern climate is humid It is humid and humid, especially in coastal areas. In addition to the cold and humid weather, there are usually many typhoons, heavy rainfall, and very humid conditions. Therefore, doors and windows in the south must first be better than other doors and windows in terms of wind pressure resistance and water tightness. products. At the same time, the southern region is humid and cold, and there is also a return to the south, for Therefore, it is necessary to ensure that the selected doors and windows have appropriate thermal insulation properties

Northern my country has obvious seasonal changes and is prone to wind and sand; taking into account the characteristics of the northern climate, it is best to use doors and windows. There are some local regulations, such as: buildings with more than 7 floors The upper limit is to use outward-opening windows. The most important thing is that it is hot in summer and cold in winter, so a door and window with good insulation effect can bring a lot of comfort to the room and save a lot of energy consumption. In addition, according to the survey, it is used in the north. The indoor temperature of plastic steel doors and windows can be 4-5 degrees higher in winter than that of rooms with wooden doors and windows.;Using double-glazed glass in northern areas will provide better results.

2) Check the appearance acceptance of doors and windows

A. The doors and windows push and pull smoothly, the surface is smooth and clean, and there are no serious scratches, profile deformation or color difference.

B. The hardware accessories are complete, the position is correct, the installation is firm, and the latch can be opened and closed flexibly.

C. Sealing quality: when the doors and windows are closed, there are no obvious gaps between the sash and the frame, and the sealing strips are not loose, falling off, or exposed.
