What is the difference between the so-called broken bridge aluminum doors and windows and ordinary aluminum alloy doors and windows?

At present, many self-built houses will choose broken bridge aluminum when choosing doors and windows, because broken bridge aluminum itself is more advanced than ordinary aluminum alloy doors and windows. First of all, it has better sealing performance and longer service life. After all, doors and windows are exposed to the sun, and the service life of broken bridge aluminum is 5~ 10 years longer than that of ordinary aluminum alloy.

Although it is a little expensive, it at least increases the service life. In fact, careful conversion is not much difference. Moreover, the broken aluminum doors and windows have excellent sealing performance and obvious sound insulation effect, which is incomparable to aluminum doors and windows. In fact, aluminum alloy doors and windows were still very popular in previous years. At that time, I replaced the doors and windows of my hometown with aluminum alloy, about six windows and one door, and the cost was about 10000 yuan. Now if I want to replace them with broken bridges, it should be about 20 thousand to 30 thousand.

If there were broken aluminum doors and windows, I would definitely choose this one, because now I find that aluminum doors and windows have been deformed after several years of use.

Moreover, due to thermal expansion and contraction, some glass will sink, which is the biggest shortcoming of aluminum alloy doors and windows, so now aluminum alloy doors and windows or Shuo steel doors and windows have basically withdrawn from the market.

But now there seems to be a new kind of doors and windows, which belongs to plastic-wood structure. Although heavy, it is well sealed and slightly expensive. It is made of 70% plastic and 30% wood, so it won't crack and has a thicker appearance. It has also become a new decoration method for many rich families.
