Doors and windows are a very important item in decoration. Many laypeople actually know very little about purchasing doors and windows. Doors and windows can not only protect us from wind and rain, but their quality also directly affects your comfort after moving in. If you go to the building materials market and choose windows, you will find that they are different from other products.

Just buy windows Just like choosing and assembling a computer, the configuration of each hardware is different, which affects its performance. The main components of windows include profiles, glass, insulation strips, sealing strips, hardware accessories, etc. If you don’t know how to choose, it’s easy to get into trouble. As someone who has been there, I suggest you follow the following \”6 Don\’t Buy\” principles.

1. Do not buy ordinary aluminum alloy doors and windows and plastic steel windows

The mainstream doors and windows on the market now are broken bridge aluminum doors and windows. CompareCompared with plastic steel windows that are easily deformed and ordinary aluminum alloy windows with poor thermal insulation properties, broken bridge aluminum doors and windows will have better performance in all aspects and have a longer service life.

Broken bridge aluminum Doors and windows are upgraded versions of ordinary aluminum alloy doors and windows. This kind of windows are essentially aluminum doors and windows, but considering that aluminum alloy conducts heat quickly, the heat insulation effect is not ideal, so the broken bridge aluminum doors and windows are actually added with nylon PA66 heat insulation strips on the basis of ordinary aluminum alloy doors and windows.

With this Insulation strips and windows not only have better sealing effect and sound insulation, but also have the effect of thermal insulation and energy saving, which perfectly make up for the shortcomings of old window products.

2. Do not buy doors and windows produced by street shops or small factories

With the popularity of broken bridge aluminum doors and windows, Some unscrupulous businesses have seized the opportunity, taking advantage of consumers\’ greed for cheap, and attracting consumers to buy their broken bridge aluminum doors and windows at low prices. For example, you will find that when you buy a small shop on the street The price of the broken bridge aluminum you inquired about is much lower than the price quoted by the brand door and window store.

As mentioned before, doors and windows are customized products. If you choose the windows with the mentality of \”choose which one is cheaper\”, you will definitely be disappointed that some small factories do not produce them at all. The license and processing equipment are also limited, and the profiles will be used for you with poor quality. If you use high-quality recycled aluminum, use very thin glass, and pair it with PVC insulation strips and fake hardware, you will never see any clues. But after a year or two, there will definitely be problems with the doors and windows. If you look for after-sales rights protection, you may not be able to find anyone.

3. Don’t buy dull aluminum windows

For windows, the quality of the profiles is particularly critical. If you want to know the quality of the profiles,You can observe the cross section of aluminum. If the cut is bright, smooth and burr-free, it is virgin aluminum. However, if the aluminum is dull, has burrs, and has fine particles on the surface, most of the aluminum is recycled aluminum.

The disadvantage of using recycled aluminum as doors and windows is that over time, the hardness will not reach the standard. It is really difficult to withstand the wind and rain for many years. Hanging and easily discolored.

4. Do not buy doors and windows with a wall thickness less than 1.4mm

If the wall thickness of broken bridge aluminum doors and windows is less than 1.4mm, don’t buy it. The new national standard has clearly required it to reach 1.8mm. The international standard thickness determined before this was 1.4mm. There will always be some unscrupulous businesses that cut corners. Therefore, we must be cautious when choosing windows. to goCheck. Even if the wall thickness is a little thin, it is easy to cause problems.The overall wind pressure resistance will become worse, especially against typhoons. weather time.

5. Do not buy windows without the 3C mark on the glass

Glass takes up doors and windows More than 70% of the area, therefore, its quality is directly related to factors such as sound insulation, air leakage, safety, and lighting. When we choose window glass, we must look for the brand of the original glass. Major door and window brands will choose CSG and Xinyi.

Tempered glass must have the 3C mark. If there is no such mark on the glass, or there is this mark, but it can be scraped away with a fingernail, such glass Cannot choose. The thickness, flatness and light transmittance of the glass produced by small workshops cannot be compared with the glass of regular brand doors and windows.

6. Do not buy doors and windows that use off-brand hardware accessories

The hardware accessories of doors and windows are not just some screws and handles that you see, it also has a whole set of othersContains locks, hinges, hinges,More than 100 precision component combinations such as actuators, locking points, and bases, each component They play a very important role and even directly affect the service life of doors and windows. There are actually many tricks when choosing window hardware accessories.

If you don’t buy their hardware, the window will not be able to open normally because other brands of hardware cannot match it. But in fact, this is not the case. The so-called \”original hardware\” \”Factory\” is just what they say. In fact, the cost of even a set of these hardware accessories is less than 100 yuan. If you get it, then for them, the profit margin will be greater.

There are many processing factories in Hebei, Jiangsu and Zhejiang that can produce any hardware accessories you need to put a LOGO name on. You think they are supporting hardware produced by large aluminum factories, but in fact they are just the work of small workshops. .Hardware accessories You definitely get what you pay for, so when choosing windows, be sure not to search for hardware accessories. Be sure to buy hardware accessories from regular brands. Currently, the most widely used brands for door and window accessories include HOPO, Silkilia, Paige, Jianlang, etc. .
