In home decoration, doors and windows can not only play a defensive role in home security, but also have a decorative effect. However, there are many brands of doors and windows on the market, and there are many kinds of doors and windows. And the bridge cutoff aluminum alloy doors and windows are more popular in recent years. Is the bridge cutoff aluminum alloy doors and windows good? In the market of doors and windows with many brands and varieties, how to choose and purchase bridge cutoff aluminum alloy doors and windows? Now let's get to know it together with the editor!

 How about bridge cutoff aluminum alloy doors and windows?
How about bridge cutoff aluminum alloy doors and windows? Broken bridge aluminum alloy doors and windows is a new type of doors and windows that has emerged in recent years. This kind of doors and windows are made on the basis of the old aluminum alloy windows and are improved to improve the thermal insulation performance of doors and windows. This kind of door and window uses PA66 nylon to separate the indoor and outdoor two layers of aluminum alloy and closely connect them into a whole, thus forming a new type of heat insulation aluminum profile. Because of their different connection methods, they can be divided into glue injection type and threading type. The doors and windows made of bridge cutoff aluminum alloy have a very good heat insulation effect, which has solved the fatal problem of aluminum alloy's fast conduction and heat dissipation, which does not meet the requirements of energy conservation.
 
In addition, some new structures are also used for production, thus solving the problem of poor sealing of aluminum alloy sliding windows.
 
Advantages of bridge cutoff aluminum alloy doors and windows
1. The thermal insulation performance of bridge cutoff aluminum alloy doors and windows is good, because they are made in the form of rubber strip sealing, so their water tightness, air tightness and thermal insulation performance are good.
2. The waterproof function of bridge cutoff aluminum alloy doors and windows is also very good. Because of the drainage system structure when they are made, the drainage is very smooth.
3. The bridge cutoff aluminum alloy doors and windows have remarkable anti condensation and frost effects. Because they are of multi-channel sealing structure, their gas and water are in equal pressure balance.
4. The anti-theft and anti loosening devices of the bridge cutoff aluminum alloy doors and windows are very good, so that the household safety is well guaranteed.
5. The bridge cutoff aluminum alloy doors and windows also have good noise prevention and sound insulation effect, because they are made of hollow sound insulation glass, and the joints are also tight, so they can be free from noise interference.
6. The bridge cutoff aluminum alloy doors and windows have high strength and will not deform, so maintenance is unnecessary.
7. There are many colors of bridge cutoff aluminum alloy doors and windows, and the internal and external colors can be combined randomly.
8. The quality of bridge cutoff aluminum alloy doors and windows is very good, and they are green building materials, which can be recycled.
 
How to purchase bridge cutoff aluminum alloy doors and windows
1. When purchasing bridge cutoff aluminum alloy doors and windows, the wall thickness of the profile shall be greater than or equal to 1.4mm.
2. When purchasing bridge cutoff aluminum alloy doors and windows, it is necessary to check whether PA66 nylon is used as the heat insulation strip.
3. When purchasing bridge cutoff aluminum alloy doors and windows, their packaging must be the original product of the original factory.
4. When purchasing bridge cutoff aluminum alloy doors and windows, its strength, thickness and oxide film shall be checked to see whether they conform to national standards. According to national regulations, the wall thickness shall be more than 1.2 mm, the tensile strength shall be 157 N/mm2, and the yield strength shall be 108 N/mm2, and the oxide film thickness shall be 10 microns.
