How much do you know about the secret of broken bridge aluminum doors and windows?


The evolution of doors and windows, whether you are walking in a country lane, a skyscraper, or a busy commercial street, you will see all kinds of windows. The windows have entered into our lives deeply from only one opening to today's various types.

Although the broken bridge aluminum is very windy now, it seems that many owners do not know what the broken bridge aluminum is? How to choose broken bridge aluminum? The backstage will be full of inquiries from the owners. Not much to say, today I will talk to you about the broken bridge aluminum.

1. Aluminum

To choose primary aluminum, the so-called primary aluminum is relative to secondary aluminum. Primary aluminum is pure aluminum extracted from an electrolytic cell using bauxite obtained from bauxite mining. Recycled aluminum is the aluminum produced by re-melting discarded aluminum materials, such as scrap car parts, cans, aluminum alloy doors and windows, etc. What if you don't know how? Then let the manufacturer issue you a door and window inspection report.

2. Look at the wall thickness

Do many people think that the wall thickness of aluminum doors and windows is just 1.4, and the new national standard for aluminum alloy doors and windows in 2021 has come out. Content requirements and clarification, the wall thickness must reach 1.8 wall thickness. If the shopping guide you asked is still recommending 1.4 or 1.6 to you, then be careful, it is either cleaning up the inventory or trying to trick you.

3. Look at the heat insulation strip

The thermal insulation strip should be made of PA66 nylon. If he said that the PVC thermal insulation strip is good, it must be even more unbelievable. There is also a very important point, whether the folding process of the aluminum heat insulation strip is diagonal or integral bending, if it is diagonal, it is prone to fogging in the later stage.

4. Window width

When buying windows, the shopping guide tells you six, five, seven, and eighty-five, which refers to the width of the narrow part of the window. Building energy-saving standards require that those below 75 will be eliminated in the future. Remember not to choose below 75.

In fact, as long as you know more about the relevant doors and windows before purchasing, you will not take a detour. Through the brief introduction of the Baydee uPVC Profile, I believe you have understood it, and we will continue to share the knowledge of doors and windows.
