0 1 price and brand of system doors and windows
Summary: In recent years, the development of system doors and windows is blowout every year, and consumers can easily buy many brands of system doors and windows in the market.
The price range of domestic mainstream system window brands is 1000-3000 yuan /m2, which exceeds the per capita purchasing power level of cities and belongs to decoration luxury goods.
Details: the price of system doors and windows is linked to the performance of doors and windows, the quality of materials used and the brand size. If you shop aimlessly, it's easy to buy products that don't meet your identity. According to the small report made by fan Xiang Peng this year, the brand and price differences of system doors and windows can be roughly divided into the following three types:
1, the average price is around 1000~ 1500 yuan, and it focuses on cost-effective system doors and windows (average price = total price/total area), which may have three characteristics: (1) materials and product workmanship are not top-notch; (2) the brand awareness is small; (3) Not all series in the brand are worth buying, and the main models are often the most cost-effective;
2, the average price 1500~2500 yuan high-end brand system window; Its three possible characteristics are: (1) one or more of materials, product workmanship, product performance and brand awareness are top-notch; (2) The configuration and performance of doors and windows are mostly superior to the first gear; (3) There are many parallel imports posing as high-end brands;
3. The average window price of well-known systems is more than 2,500 yuan; Its three possible characteristics can be summarized as follows: (1) German and Japanese imported brands, and a few domestic first-line brands; (2) In the past, the product had obvious advantages, but now it is not as good as before; (3) It is not recommended for home improvement consumers;
In-depth: If consumers want to compare the prices of doors and windows of different brands and series, they should examine the sum of structure (Chapter 2 below), product materials (Chapter 3), workmanship (Chapter 4), installation (Chapter 5) and design (which has little to do with the doors and windows themselves).
The average price of doors and windows of the same brand and series system is not fixed. Take a brand of 70 series system windows represented by Peng Ge as an example, the average price of users is about 1 100 yuan/㎡. However, in some cases, the standard 5+12A+5 insulating tempered glass plus laminated insulating glass and Low-e glass is changed to internal opening and internal pouring hardware.
In addition to glass and hardware, there may be other small additions to the system doors and windows: cavity filling, appearance color, supporting screen, splicing square pipes, value-added services with delayed warranty, etc. This will also slightly affect the price of doors and windows.
Performance difference between 02 system doors and windows and non-system doors and windows
Summary: Most domestic manufacturers of system doors and windows will take their doors and windows products for inspection, so as to obtain an "identity certificate" marked with five specific performance parameters of doors and windows: wind pressure resistance, air tightness, water tightness, heat preservation and sound insulation;
This "ID card" proves (1) that my performance is better than that of non-system windows. (2) My performance is solid.
Details and Depth: Consumers can obtain the performance of the doors and windows of the system through the five performance parameters of "wind resistance, air tightness, water tightness, heat insulation and sound insulation". For example, wind resistance means that when doors and windows are closed, doors and windows with higher wind resistance can withstand stronger storms without being damaged.
Generally, the wind pressure resistance standards for doors and windows formulated in various places are between 3 and 5 (the wind pressure resistance grades of high-rise buildings and coastal areas are higher). Most non-system doors and windows generally rely on a series of thickening methods, relying on experience (the high-rise windows made before are a bit rickety, this time they use a larger series with thicker glass) to reach the passing line.
The local basic wind pressure has been considered in the structural design of system doors and windows, such as increasing the width of frame materials (as well as non-system windows), increasing the wall thickness of profiles and the number of cavities. Therefore, after inspection, a higher wind pressure resistance grade (6-8) can be obtained, which ensures the safe use under the once-in-a-century typhoon.
Another important structural embodiment is that the wind pressure resistance of system doors and windows is stronger than that of non-system doors and windows-strengthening the middle stile (and strengthening the splicing). At present, it is popular to separate doors and windows with large fixed openings, rather than the "only long but not thick" system, which can not meet the side effect of the overall door and window enlargement-insufficient support.
Causes the whole door and window to shake in the wind, and the window sash feels obvious shaking when opening and closing. Generally, for windows above 1.8 m (not excluding unprofessional merchants), reinforced stiles or reinforced splicing pipes will be used for system doors and windows. Thickened high heels are equivalent to the Pumbaa brothers who have been married for ten years, and they are no longer afraid of being blown away by the typhoon ... In this way, the problem of "bending resistance" is well solved because the window is too big.
(Schematic diagram of reinforced middle stile-the white part protruding outward is reinforced middle stile to enhance bending resistance; The small circle is the glue injection connection process between the middle stile and the aluminum pin of the window frame, and the connection strength is just right)
Another example is air tightness and water tightness, which together represent the "tightness" of doors and windows. Refers to the ability to prevent rainwater and air from infiltrating into the room after the doors and windows are closed.
Watertightness classification, the higher the level, the better;
Air tightness classification, the higher the level, the better;
Non-system doors and windows will do a lot worse in this respect, especially for non-system sliding doors and windows, "air leakage in windy days and rain leakage in rainy days" will be particularly serious:
System sliding doors and windows, through the rubber strip top seal, hidden drainage, high and low rails (sliding windows), composite rubber strips and other structures, so that sliding windows can also have 4-5 air tightness and water tightness, even higher than some non-system external doors and windows (note? Because of structural factors, the sealing performance of sliding doors and windows is naturally worse than that of windows that open outside, open inside and fall inside. )
The system has inverted doors and windows with external opening and internal opening (note: the air-water tightness of the system with external opening and internal opening is 5-6, and the tightness is generally 6-8; The multi-channel sealing structure, which has the greatest influence on sealing performance, basically shows that there is no wind or rain after the window is closed.
There is also the K value of thermal insulation performance, which is the main index used to measure the thermal insulation performance of doors and windows. The lower the k value, the better the ability of doors and windows to block indoor and outdoor temperature exchange, that is, the better the thermal insulation performance of doors and windows:
The biggest difference between system doors and windows and non-system doors and windows lies in thermal insulation performance. For example, insulation strips with larger width for system doors and windows, more cavities of profiles, isothermal structure, multi-channel sealing (i.e. improving water tightness and air tightness at the top, interacting with each other), cavity filling, glass with lower K value (non-system windows can also be equipped with glass with lower K value), etc., can widen the gap between insulation and non-system doors and windows:
Finally, the sound insulation performance is mainly related to the choice of seal and glass. Everyone can understand it, so I won't introduce it much. Compared with non-system doors and windows, the advantages of system doors and windows in sound insulation performance are mainly: better sealing and being able to withstand larger and thicker glass. The five attributes of system doors and windows are closely related to each other, because the overall structure of system doors and windows contributes to the * * * play of its five attributes.
Performance stability of doors and windows in 03 system
Summary: After reading the performance difference between system windows and non-system doors and windows in Chapter 2, many people will have questions: "The five performances of system windows seem useless, why not seal and keep warm?" It doesn't feel worthwhile to spend so much money ... "In fact, the good performance of system doors and windows should be seen together with 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 2~5 years;
Generally, manufacturers of system doors and windows who are not confident will say "guaranteed service life 15-20 years", while those who are confident will even say "the life and performance of doors and windows are the same as that of buildings".
Details: Most of the doors and windows are made of ordinary materials, and the boss will use low-priced and low-quality raw materials that do not meet the national standard in order to save money, so it is difficult for him to adapt to the performance requirements of high-demand environment (high demand refers to the window-mounted environment on the edge of elevated buildings or people who are particularly sensitive to noise), and the performance of doors and windows is obviously declining year by year (most obviously, the hardware is easy to rust and break, the adhesive tape is aging rapidly, and the doors and windows are not sealed every year).
The main materials such as profiles, hardware, glass, heat insulation strips, rubber strips and tops used in the production system windows are generally exported by professional R&D personnel hired by manufacturers according to different performance requirements, and customized to upstream raw material processing enterprises. Although the cost of customized molds, mass customized raw materials and storage will increase, "fit" materials can be used for doors and windows of different specifications.
Moreover, the more quality-oriented the factory, the more it will process the raw materials of the goods from the upstream, which is much more reliable than the "three no materials" used by ordinary doors and windows in small workshops on the street (its essence is strictly in accordance with the requirements of national standards):
For example, aluminum profiles that meet the national standard ensure the strength of doors and windows, and higher-precision hardware ensures reasonable load bearing, which is smoother to use, has a longer opening and closing life, and the glass produced by glass processing plants with better quality is not easy to enter water vapor, resulting in functional failure. The rubber strip with higher glue content has better elasticity, better sealing performance and longer service life, and the silicified wool tops are waterproof and will not fly around.
These two reasons make the life of the system doors and windows longer than that of ordinary doors and windows, and the performance is basically stable within the life range.
In-depth: What kind of system door and window materials have more stable performance? See below. (1) profiles, the system doors and windows profiles generally have no pits, and there is little difference in brand quality between large and small profiles. (2) Hardware source, imported hardware, domestic first line, can ensure stable performance. Special attention: ask not only the hardware brand of the handle, but also the whole set of hardware brands; (3) Brand and material of rubber strip, heat insulation strip and top cover; Special note: merchants can provide purchase and sale vouchers. (4) Glass, glass deep processing factory should have a reliable source, specifically, you can ask merchants whether the factory has a glass processing certificate:
Advantages of 04 system door and window manufacturers
Summary: Because the system window has more processing procedures and uses more auxiliary materials than ordinary doors and windows, it requires higher processing accuracy. Therefore, only a factory that reaches a certain scale can produce products with touching details, and the door and window processing factory with general strength can't do the details well.
Details: the manufacturers of system doors and windows are concentrated in two categories: first, there are well-known local door and window manufacturers with a certain scale; 2. Large door and window enterprises with nationwide supply and high degree of machine automation. These two types of manufacturers have high processing accuracy and the ability to supply the whole country.
High machining accuracy: the increase of equipment procurement cost increases the fixed assets investment of door and window enterprises, which improves the overall threshold of the door and window industry of the system to a certain extent and can ensure good accuracy.
Moreover, with the increasing degree of machine automation in system door and window processing enterprises, the degree of workers' participation is less and less, and the accuracy of the doors and windows produced is more and more guaranteed.
Delivery of finished windows: Now the brand of system doors and windows is very similar to the whole wardrobe customization industry a few years ago, and the door and window market is evolving towards commercialization and branding. For example, in Guangdong, Shandong, Northeast and other provinces where the door and window industry is relatively developed, many brands have the ability to send "finished windows" to all parts of the country:
Therefore, consumers can buy more brands, no longer only ordinary doors and windows produced by local small processing factories (or workshops), so consumers who have higher requirements on the performance of doors and windows have better choices.
Moreover, "finished window" is more conducive to the protection of door and window products. Aluminum alloy and glass are easy to be scratched and scratched during transportation, and too obvious traces will make perfectionist consumers unhappy (a small number of scratches are hard to avoid). "Finished windows" are basically protected by frames and glass during transportation, which can reduce scratches and reduce the possibility of glass accidents.
In-depth: Of course, not all system window brands have sophisticated equipment, and most of them are actually on the road of pursuing numerical control mechanization of production equipment. This is also the place that consumers need to consider when buying. Brother Peng would like to give the following two suggestions:
1) The more advanced the equipment with less manual intervention, the stronger the production strength of the manufacturer. Consumers can compare the factory appearance, photos or videos of the equipment and the on-the-spot investigation of the merchants (ps: on-the-spot investigation of the door and window factory and visiting the installation of the merchants are the two best skills for consumers to choose).
2) Before fully automatic production is realized, "workers' experience and standards" are as important as good equipment. Consumers can make a comparison by asking the merchants for photos or videos of engineering and workshop processing standards and reward and punishment systems, as well as field visits. If consumers care about the production capacity of door and window enterprises, they can find and eliminate a large number of door and window enterprises with poor processing level.
05 system doors and windows installation
Overview: After the system window is delivered to the home, only the installer needs to install the window frame, glue and waterproof, and install the glass. Compared with semi-finished windows, it is necessary to install and debug hardware and lock holes on site. , eliminating most of the steps that require precision and debugging.
Therefore, the difficulty of installing doors and windows and the limitation of the level of installers are greatly reduced. Therefore, the user experience will be better after the system window is installed and delivered.
Details: The installation of doors and windows affects 30% of the user experience after delivery. Compared with the "finished window" of non-system windows, the "finished window" of system doors and windows has the greatest advantage that it does not need hardware assembly and debugging time.
System window manufacturers will directly complete the drilling, milling, installation and finished product debugging of the most difficult hardware installation positions in the factory, which has the advantages of high precision, smooth and beautiful operation experience and good sealing performance.
In-depth: Although the system window will be more expensive than ordinary doors and windows, there must be merchants (emmm, this number) who want to save money on installation, so the system window should also focus on the installation factors-
(1) level of workers' experience (it is not good for bosses who don't know how to install to outsource to installation masters who just entered the business); (2) Installation of auxiliary materials, mainly screws, sealants and foaming agents, must ensure the good quality used by merchants (especially screws and sealants); (3) Whether there are standards and specifications for installation, and whether someone decides the degree of installation details in professional supervision are indispensable links for the system window company.
Future trend of windows and doors in 06 system
Finally, talk about the trend of the system window. With the appearance of system windows, the price of doors and windows in the future may be directly linked to the performance and materials of doors and windows, so as to ban or improve "low-end" door and window shops with poor quality and "high-end" door and window shops with high prices.
Although the current system window ≈ high price is not a product that most consumers can afford, in the next few years, with the upgrading of processing tools, more system window brands will appear and the market situation will develop:
With the aging of windows in 1990s and 00s, there is a strong demand for renovation.
National building energy efficiency standards are getting higher and higher. In the future, more cities will introduce the requirements for the K value of doors and windows, which will greatly drop the blue ocean ~ ~ ~
The appearance of system window caters to the consumption concept of the younger generation after 80s and 90s, because it can really improve consumers' requirements for thermal insulation and sound insulation of doors and windows, the aesthetic requirements of large fixing and small opening, and guarantee the service performance of 15-20 years.
The price of the system window will tend to be civilian, so that more consumers can afford it and feel cost-effective.
However, in the future, will the system window really blossom, or will it form a unified brand like home customization and overall wardrobe, or will it eventually become the reincarnation of plastic steel windows a few years ago and die out in bad money driving out good money. Everything has yet to be tested by time.
