Many homeowners will hear the name broken bridge aluminum when they buy doors and windows. What is the difference between the broken aluminum and our common plastic steel windows? Here we will learn about the steel window and the broken bridge together with Qijia Xiaobian. The difference between aluminum !
Before understanding the differences between plastic steel windows and broken aluminum , we first learned about what steel windows are and what aluminum is broken.
What is a plastic window
It appeared in various buildings in the 1990s. It was actually made of ordinary aluminum alloy doors and windows, and its main material was polyvinyl chloride resin because it was easy to handle and produced at a low cost. It is widely used because it is energy-saving, beautiful, and sound-insulating. 
What is broken bridge aluminum
It is actually an upgraded product of aluminum alloy doors and windows. Compared with ordinary aluminum alloy doors and windows, it has very good heat insulation. Even if the outdoor temperature is high, we can't feel the outdoor in the room where aluminum windows with broken bridges are installed. high temperature. And its insulation is also very good, in the winter indoor temperature will not be scattered through the material to the outside, so that energy-saving insulation effect can be achieved. 
Difference between plastic window and broken bridge aluminum
Here we specifically talk about what is the difference between the two!
(1) Watertightness
Plastic steel window: Its opening fan and frame are not on the same plane, and it is hollowed inwards. It is easy to collect water. It needs to drain through the drainage groove, and it will not cause condensation in winter.
Broken Bridge Aluminum: Its opening fan and frame are in the same plane. Although it is not easy to collect water, it may cause condensation in the winter.
(2) Wind pressure resistance
Plastic window: It has steel liner support inside, but there is no connection between steel liner and steel liner, so the strength is weak.
Broken Bridge Aluminum: Its high wind pressure resistance.
(3) Lighting performance
Plastic window: poor lighting
Broken Bridge Aluminium: Better Lighting of about 10%
(4) Sound insulation performance
Plastic window: better sound insulation
Broken bridge aluminum: The sound insulation is weak, so because it is made of aluminum alloy inside, the acoustic energy transmission will be stronger. 
(5) Air tightness
Plastic window: Its PVC profile is made by welding, so there does not appear to be a gap and the airtightness is good.
Broken bridge aluminum: while its profile is fixedly connected by bolts, there will be some gaps and poor air tightness.
(6) Insulation performance
In the various profiles of doors and windows, PVC profile is the best insulation properties, its heat transfer coefficient is 1/357 of the steel, is 1/125 of the aluminum profile, the ratio of the heat transfer coefficient of the whole window of the aluminum profile and the PVC profile is 1.44 times, that is, the energy loss in winter and summer is 1.44 times that of plastic steel windows.
(7) Fire performance
Plastic window: it is flame-retardant
Broken Bridge Aluminum: It is not flammable, so the fire resistance of aluminum broken bridge will be better
(8) About lightning protection and static electricity
Plastic window: Since PVC plastic is a non-conductive insulator, its lightning protection effect will be better.
Broken Bridge Aluminum: Aluminum alloys are good electrical conductors with poor lightning protection and are prone to static electricity. 
Xiao Bian's words: Through the above 8 points, you must have understood the difference between plastic steel windows and broken aluminum bridges ! The above is the relevant knowledge of Xiao Bian and everyone to explain the difference between plastic steel windows and aluminum broken bridges, I hope you can Give you some references!
