The benefits of broken bridge aluminum doors and windows, why should we recommend customers to make broken bridge aluminum doors and windows? After understanding it, you will know that the bridge cutoff thermal insulation aluminum alloy doors and windows are increasingly popular in the market because of their outstanding advantages, such as high strength, good thermal insulation, good rigidity, good fire resistance, large lighting area, good corrosion resistance, high comprehensive performance, long service life, good decorative effect and so on. The high-grade bridge cutoff heat insulation aluminum alloy doors and windows have gradually become the first choice of high-grade architectural windows

why is it called 'broken bridge insulation aluminum'

"bridge" in the name of "broken bridge insulating aluminum" refers to the "cold and hot bridge" in the sense of Materialogy, and the word "broken" refers to action, that is, "breaking the cold and hot bridge"

specifically, because aluminum alloy is a metal, its heat conduction is relatively fast, so when the indoor and outdoor temperatures differ a lot, aluminum alloy can become a "bridge" to transfer heat. If such materials are made into doors and windows, its heat insulation performance is poor. The bridge breaking aluminum is to disconnect the aluminum alloy from the middle. It uses heat insulation strips to connect the disconnected aluminum alloy, so that the heat can not easily pass through the whole material, and the heat insulation performance of the material will be improved. This is the origin of the name "bridge breaking heat insulation aluminum"

bridge cutoff aluminum doors and windows generally contain two main bodies: Bridge cutoff thermal insulation aluminum profile and insulating glass

12. Broken bridge insulation aluminum has many opening forms, which is comfortable and durable

there are flat open type, inward inclined type, upward suspended type, push-pull type, flat open type and inward inclined combined type, which are suitable for public buildings, residential quarters and municipal engineering; High quality hardware accessories are durable, the operating handle is humanized design, beautiful and comfortable, convenient and flexible to open. Each use action has been tested, and the number of fatigue tests has reached more than tens of thousands of times. The sliding is easy and silent. The mature and perfect door and window processing technology, high-precision program control processing center for production, and the quality is stable and guaranteed

material characteristics of bridge cutoff thermal insulation aluminum

(1) bridge cutoff aluminum alloy doors and windows are high-grade aluminum alloy doors and windows. It is the fifth generation of new thermal insulation and energy-saving doors and windows after wood windows, iron windows, plastic steel doors and windows and ordinary color aluminum alloy doors and windows. Its surface can be painted in various colors

(2) the composition structure of bridge broken colored aluminum alloy doors and windows combines the environmental protection of wood windows, the firmness and safety of iron and steel windows, and the commonness of thermal insulation and energy saving of plastic steel doors and windows. Its structure is more complex than ordinary aluminum doors and windows, and its cost is higher. Ordinary colored aluminum does not have heat insulation strips, and it does not heat preservation or save energy. It is only sprayed on the surface

(3) the section wall thickness of bridge cutoff aluminum alloy doors and windows shall strictly comply with the national standard. The wall thickness must be between 1.4 and 2.0mm, because the wall thickness is related to the assembly technology and the stability and safety of the doors and windows. The wall thickness of ordinary color aluminum doors and windows is generally less than 1.4mm

(4) bridge broken color aluminum doors and windows are assembled with special corner codes of more than 3mm, and corner glue should be injected into the corner to seal. While ordinary doors and windows are only connected by rivets or screws, which is not strong and safe, but the cost is low. And there will be no problem for adults standing on the assembled color broken bridge aluminum doors and windows to walk around. There is a great difference in technical requirements between those assembled by complete sets of equipment and those assembled by manual on-site operation. The special bridge cutoff aluminum profile and ordinary aluminum profile are not of the same grade and cannot be compared

how to judge the advantages and disadvantages of bridge broken aluminum profiles

a, profile wall thickness:

generally do home decoration products. Most door and window factories choose products with high yield, that is, products with relatively thin wall thickness, to reduce the cost. 1.3 thickness is lower than the national standard. The national standard stipulates that the thickness of profile shall be greater than or equal to 1.4mm

b, thermal insulation strip:

thermal insulation strip is the most critical part of bridge broken aluminum profile. PA66 nylon must be used, which is stipulated by the national standard. However, at present, many manufacturers in the decoration market use cheap PVC plastic thermal insulation strip, which will seriously affect the service life and safety of products
