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 and finally form high-performance system doors and windows.
Differences between system doors and windows and common doors and windows
Common doors and windows = Economy, unguaranteed performance, imperfect matching and homogenization.
System doors and windows = specialty, details, quality, process control and trend.
Basic definition of system doors and windows
System doors and windows: the integrated technical solution of building doors and windows is supported by a complete technical system and covers all technical links of doors and windows. System doors and windows are composed of door and window systems (elements).
Materials: Profiles, reinforcements, accessories, seals, hardware, glass, etc.
Structure: node structure, corner and muntin connection structure, splicing structure, installation structure, logical relationship between each material and window assembly, etc.
Technology: The design method of doors and windows, the processing technology and tooling of doors and windows, and the installation technology of doors and windows.? Performance: including physical properties, mechanical properties, repeated opening and closing, weather resistance.
Of course, there are also some drivers of system doors and windows brands in China, including common xuge doors and windows, suifu doors and windows, becquero doors and windows, Milan windows, etc.
The brand and price differences of system doors and windows can be roughly divided into the following three types:
1. The main cost-effective system doors and windows with an average price of about 1000~1500 yuan (average price = total price/total area) have three possible characteristics:(1) the material quality and product workmanship are not top;(2) the brand awareness is small;(3) not all series of brands are worth buying, and the main models are often the most cost-effective;
2. Medium and high-end brand system windows with an average price of 1500~2500 yuan; Its three possible characteristics are:(1) material quality, product workmanship, product performance, one or more of the brand awareness belongs to the top;(2) the configuration and performance of doors and windows are mostly better than the first grade;(3) There are a lot of parallel goods pretending to be middle and high-end brands;
3. Well-known system windows with an average price of more than 2500 yuan; Its possible three characteristics are summarized as:(1) brands imported from Germany and Japan, and a small number of domestic frontline;(2) in the past, the advantages of products were obvious, but now it is not as good as before;(3) it is not recommend for home decoration consumers;
Differences between system doors and windows and non-system doors and windows
Overview: most domestic system door and window manufacturers will take their own door and window products for inspection, thus obtaining a specific "wind pressure resistance, air tightness, water tightness, thermal insulation, sound insulation
Performance Stability of system doors and windows
Overview: After reading the second chapter, the performance differences between system doors and windows and non-system doors and windows, many people will have doubts: "The 5 major performance of system windows seems to be useless, isn't it better to seal and keep warm? I don't think it's worth spending so much money... "In fact, the performance of system doors and windows is good, and it should be seen together with the stable performance.
A large part of the cost of system doors and windows is used to maintain stable performance. Compared with many ordinary doors and windows, the real service life is only about 2 to 5 years:
Generally, system door and window manufacturers with less confidence will "guarantee that they can use it for 15-20 years", and those with strong self-confidence will even say "the life and performance of doors and windows are the same as the life of buildings 」.
Advantages of system doors and windows manufacturers
Overview: because the system window has more processing procedures than ordinary doors and windows, and more auxiliary materials is used, it requires higher processing accuracy, therefore, only manufacturers with a certain scale can produce products with touching details, and general strength door and window processing plants cannot do details well.
Details: the manufacturers of system doors and windows are mainly divided into two categories: first, the local doors and windows manufacturers with relatively famous reputation and a certain scale; Second, large doors and windows enterprises with high degree of machine automation are shipped nationwide. These two types of manufacturers have the ability to process with high precision and deliver goods to the whole country.
High processing precision: the increase of equipment procurement cost increases the investment in fixed assets of door and window enterprises, improves the overall threshold of system door and window industry to a certain extent, and ensures good precision.
