At present, the market price of customized doors and windows is really messy. To what extent? Take 110 window screen integrated window for example, the cheap one is only about 400 to 500 square meters, but the expensive one is 800 to 1200 square meters, there are even more than 2,000 square meters. What is the difference between them? There is no difference between them from the outside, so where is the problem? Today I we will give you a general comparison from three aspects: material, craft and window type.
I. Materials
1. Profiles
a. 110 window screen one-piece profiles are available in the market from 1.2mm to 1.8MM. Only one 6-meter-long profile has a price difference of tens of yuan only due to different thickness.
B, the difference between large factories and small factories: due to equipment and process reasons, the processing fee of profiles produced by small workshops is between 2,000 and 3,000 per ton, while the processing fee per ton of large factories reaches5000 to 6000 yuan, this is also a big difference!
2. Hollow glass
a. Hollow glass has non-tempered hollow, single-sided tempered hollow, double-sided tempered hollow, non-tempered hollow about 60 to 70 yuan per square meter, while double-sided tempered hollow is in each square meter more than 100 yuan.
B. There are three types of hollow glass that can be assembled with 110 window screen integrated glass, namely 5 15a 5,5 18a 5,5 20a 5. Among these three types, 5 15a 5 sound insulation the thermal performance is the worst, the sound insulation performance of 5 20a 5 is the best, and their price difference is between 25 and 30 yuan per square meter.
3. Heat insulation strip
ordinary PVC insulation strips are generally about 6000 to 7000 tons, while PA66 insulation strips are as high as 28000 yuan per ton, and imported ones are more than 30000 yuan per ton, you can calculate the difference between them!
4. Hardware
take a set of hardware for example, the price is less than 100 yuan in the low market, while the quality of a set reaches 200 or 300 yuan, especially for imported brands, it is as high as four500 yuan. The difference is four or five times.
5. Silicon sealant
when installing broken bridge aluminum doors and windows, some people used sealant for caulking for two or three yuan to save money, while others used sealant for exterior wall to meet quality requirements. For each structural adhesive, it costs more than 18 yuan. For consumers, do you want to use two or three pieces of glue to save money? Or use better quality structural adhesive for quality?
II. Craft
A complete set of production equipment in a small workshop costs tens of thousands of yuan. However, only one ordinary precision double-head saw of a large factory costs more than 60000 yuan, and the number of numerical control is more than 100,000 yuan., this kind of investment is not because big factories have money, but because their cutting precision is indeed not at the same level! This is only to compare one device, and there are several other types what about the equipment! Therefore, the investment of large factories is large, while that of small workshops is small! Who do you think is of good quality to produce products? High precision? To produce good products with standard quality, hardware investment the capital must first meet the standards, and only when the hardware meets the standards can the products reach the standards, the cost is undoubtedly higher.
3. Window shape
in fact, the production costs of different window types are also very different. For example, only one movable window square meter and one movable window square meter can be opened. The difference in cost is several times. As many!
There are still many factors that affect the cost of doors and windows, such as the research and development cost of large factories, publicity cost and so on. We will not talk about this one by one.
If you buy doors and windows, you must pay attention to the quality and safety. If you buy Li Yan, don't buy Li Gui. Buy doors and windows products, compared with the current car market: 20 thousands or 30 thousands can also buy a QQ car, just less functions, less space, shorter life span, slower running; however, if you spend hundreds of thousands or even millions to buy a Mercedes-Benz BMW, it only has more functions and stronger power. The full coefficient is higher, and the interior is more luxurious. Whether you buy QQ or BMW depends on your economic conditions and practical use.
Therefore, buying doors and windows products also depends on your own family conditions. If you are willing to solve the problem at one time, you can buy products with better quality. The price is higher, but one-time the problem has been solved without any worries. If the conditions are not allowed, you can use products with lower prices. When the conditions permit in the future, you can change the products with good quality. This is also true. It is an expedient measure.
