Comparison of the differences between home decoration broken bridge aluminum doors and windows and engineering broken bridge aluminum doors and windows
After buying a house, many people think of decoration first, but most of them are not professional and pay little attention to doors and windows. When decorating, they often believe that the existing windows can be used, but they find that the doors and windows have various problems in future use, so they regret that they should replace the doors and windows during decoration. When communicating with customers, many customers expressed their feelings, which shows the importance of doors and windows in decoration.
In the propaganda of some manufacturers, it is said that the first step of decoration is to replace doors and windows. Of course, there is a propaganda component of the manufacturer, but in most cases it is correct. The original broken bridge aluminum doors and windows should be replaced during decoration.
So why do we need to replace the existing broken bridge aluminum doors and windows? Let's compare the differences between broken bridge aluminum doors and windows made for home decoration and engineering doors and windows.
The quality of doors and windows is inseparable from materials, and materials are the basis of good doors and windows. Let's first talk about one of the three most important main materials for broken bridge aluminum doors and windows: the difference in aluminum alloy profiles of broken bridge aluminum doors and windows. The broken bridge aluminum doors and windows in home decoration doors and windows generally use high-precision aluminum alloy profiles, and the spraying of the profile surface uses high-quality weather-resistant powder, and weather resistance reaches more than 10 years.
The broken bridge doors and windows of ordinary projects use general precision aluminum alloy profiles, and the profile size tolerance is large. The powder on the surface of the profile is produced by ordinary small factories, and the poor weather resistance generally does not exceed 5 years. The doors and windows of ordinary engineering broken bridge aluminum alloy profiles will fade after a few years. During the powder spraying process, the inner surface of the outer side of the window frame is not sprayed normally, and the bottom can be seen from the profile. The anti-corrosion performance of this profile must be poor.
The most important thing about broken bridge aluminum doors and windows is the nylon insulation strip called "broken bridge". This is the key factor in determining the quality of broken bridge aluminum alloy profiles. The broken bridge aluminum alloy profiles of home decoration doors and windows are all made of nylon insulation strips produced by big-brand manufacturers. Regular insulation strips are sold by meter, which is more than 30,000 per ton. The price of nylon is more than 30,000 per ton. If the product is less than 30,000, it must be mixed with a lot of cheap things.
Many of the strips used in the engineering of broken bridge aluminum alloy doors and windows are made of PVC, and the quality of the aluminum alloy profiles cannot be guaranteed from the perspective of mechanical properties and weather resistance. The linear expansion coefficients of PVC and aluminum alloy are quite different. Under the influence of the external environment, the two cannot achieve synchronous contraction, which causes the profile itself to produce a large internal force, causing the profile to deform. If the profile is deformed, many properties such as sealing, water tightness, and energy saving cannot be guaranteed at all.
If PVC strips are used, due to the great difference between the strength of PVC and nylon strips, they cannot withstand various external forces when used on doors and windows, causing the doors and windows to fall apart, and even cause more serious accidents. Some manufacturers in the industry have had similar accidents.
Count the differences in the strips. The home decoration broken bridge aluminum doors and windows use high-quality EPDM strips, which make the doors and windows have good sealing and excellent weather resistance. The doors and windows can be opened flexibly after many years of use, which does not affect the use and will not cause the quality of the doors and windows to decrease.
Many of the broken bridge aluminum doors and windows used in the project use inferior EPDM rubber strips, which are mixed with a large amount of recycled materials. The only advantage is that the price is super low. The sealing performance cannot be guaranteed, and once the doors and windows lose their sealing, they lose their performance. This kind of rubber strip has no weather resistance and resilience at all, and various problems will occur after using it for half a year or even less.
In the use of hardware, the hardware of home decoration doors and windows are all high-quality imported hardware or domestic big brand manufacturers, while many of the broken bridge aluminum doors and windows in the engineering field are equipped with domestic small brand hardware. After one year of use, there are problems such as poor opening and corrosion. In terms of the opening method, most home decoration doors and windows choose inward opening and inward tilting, while most engineering still choose flat opening hardware.
There is also a big gap between the two in product processing technology. Home decoration broken bridge aluminum doors and windows use the method of corner code pin injection glue in the corner assembly, which has high strength and good sealing. In the processing of engineering broken bridge aluminum doors and windows, the corner code extrusion process is used, which cannot achieve good strength and sealing performance.
In terms of the glass used, the home-decorated aluminum doors and windows use high-end glass such as LOWE insulating glass, three-glass two-insulating glass, vacuum, and laminated insulating glass. The engineering aluminum doors and windows use ordinary insulating glass. There is a big gap between the two in terms of sound insulation, energy saving, safety, etc.
In the installation of doors and windows, the home-decorated aluminum doors and windows use high-quality sealants and foaming glue, and the price of sealants is generally above 20. The sealants used on engineering windows are generally products of a few dollars. Everyone knows the truth that you get what you pay for, so there is no need to say more.
There is a huge difference between home-decorated aluminum doors and windows and engineering aluminum doors and windows, and there is also a huge gap in product performance and service life, so the original engineering windows should be replaced during decoration. Of course, it needs to be explained that not all engineering windows are bad and need to be treated differently.
