Last year, all the broken-bridge aluminum doors and windows were replaced for the house in Wuxi. In the past two days, the broken-bridge aluminum windows were replaced for the house in Shanghai. The original plastic steel windows were in disrepair for a long time, and their sliding and sealing properties were not very good. My father complained that the windows were too heavy to pull. . . Forget it, just replace them all.
After two window replacement experiences, I have a certain (considerable) understanding of the entire broken bridge aluminum doors and windows market. For a novice, the broken bridge aluminum market is dangerous and deep. The difference in unit price per area is not big, but the pricing method is complicated and tricky, and the total price difference is huge. I will provide some practical experience and share it with friends in need.
The history of windows has gone through steel windows, aluminum alloy windows, plastic steel windows, and now the broken bridge aluminum windows. The window design and materials are becoming more and more scientific and reasonable. Compared with the previous windows, the broken bridge aluminum windows simply mean that the internal material combination is more conducive to thermal insulation, sealing and sound insulation. Here are a few window indicators:
1. Manufacturer, which brand of profiles is used? Choose a big manufacturer, such as Weidun or Jianmei. The prices of brand profiles and unknown brand profiles vary according to the area. The total price difference is not much.
2. For window hardware, also choose big-name ones. I recommend Haobao (domestic and imported). Domestic Haobao is enough. It is already a big manufacturer. The quality and workmanship are very good. I don’t know how much better the imported ones are than the domestic ones. And you don’t know whether the imported ones are genuine or not. It is true that the price is much higher. Therefore, there is no need to consume rationally. It has nothing to do with the difference in money.
3. Profile width, currently on the market, is 55, 60, 70, 80, in millimeters. There are very few 55 in the market. It is recommended to choose 60. It is not necessary to be as wide as 70 or 80, and if it is wider, it will look like the thick strips on the windows are not beautiful. Of course, the manufacturer will recommend you 80, because it is expensive and has high profits. Ignore him and choose 60.
4. The thickness of the double-layer glass interlayer, three numbers, respectively, are the thickness of the two glass and the thickness between the two layers of glass. This indicator is for the sound insulation effect. The actual current specifications are good enough, so you don’t need to pay too much attention to this indicator. The specifications on the market are 5+12+5, 5+15+5, and 5+27+5.
5. The level of construction and installation is very important. They have a saying that windows are divided into three parts of materials and seven parts of installation. Whether the installation is good or not directly determines the use effect. If the installation is not good, the difference in use effect is much greater than the differences in specifications. You must know more about the installation workers of the merchant. If you don't understand, tell them this sentence. One-third of the material and seven-cent of the installation means that you are an expert and understand the importance of installation. Don't fool me.
6. Next is the design of the windows.
a. Opening methods include flat opening (outward opening, inward opening), horizontal opening, and hanging window (top hanging, bottom hanging). Generally speaking, you can’t go wrong with flat opening. It has good sealing and good sound insulation. If you have a balcony with flowers and plants outside to dry clothes, you can consider moving the window. It is convenient for daily work, bathroom and When it comes to opening windows in a bedroom, if the room is small, try to open them outward. Don’t choose inward opening. Don’t hear that opening outward is dangerous. If the window falls, yes, it is safer to open inward than outward. But there is a probability issue. This kind of extremely low probability thing must be taken into account. Don’t do anything and don’t have to live. If the surrounding environment of the house is not very noisy and it is not extremely cold in winter, you can also choose sliding windows. Generally speaking, the total price after installation will be one-fifth cheaper than casement windows, mainly because you save money on hardware. If you want to be more sophisticated, you can install a top-hung window in the bathroom, because the bottom-hung window, even if it is open at ordinary times, blocks the view and does not affect privacy. You can feel free to do your business.
b. The size of the opening sash is the size of the window opening area. Note that the opening sash area should not be designed to be too large. If the opening sash is too large, it will be uncomfortable to open and close frequently. The design drawings the merchant will give you will have larger windows. Because the opening sash is large, they use less profiles, glass is cheap, and profiles are expensive. In addition, the cutting of profiles is also simple. For specific sizes, go to the physical store to feel the size you like.
c. The position layout of the opening fan, reasonable opening position, ventilation consideration, easy opening, and not blocking other operations.
Finally, pay attention to the price calculation method. There are many tricks. If the single installation area exceeds 1 square meter, the basic price is the area multiplied by the unit price, and then the price of the hardware is added. For small windows, it is calculated based on 1 square meter. In addition, the price of the hardware is a lot. Add all of these together, and the price of a small window is astonishing. If you seal the balcony, you may also need to spend money to strengthen the pillars. A few pillars are enough to shake your original budget. . . There are also various additional pricing methods with different opening methods. Also ask if there are any window installation fees and removal fees for old windows. The removal fee package does not include removal of the old windows. This cannot be listed one by one. It is recommended that you don’t just look at the unit price, but the total price. You must ask the merchant to provide detailed quotations, indicate the material specifications and brands, and allow the merchant to quote the prices of several different options.
