Although widely used steel doors and windows, but due to the outstanding performance of broken aluminum doors and windows, in the market, broken aluminum doors and windows gradually take advantage. What are the advantages of this? Today's commercial housing will have a balcony design, and most people will also choose to seal up the balcony, the use of broken aluminum doors and windows is also more common, today we come to understand what broken bridge aluminum doors and windows.
| 1. Wind pressure resistance of broken aluminum doors and windows |
Although the steel window has steel lining support, there is no connection between the steel lining and the steel lining, so there is no broken aluminum alloy in strength, and the wind pressure strength is lower than that of the broken bridge aluminum alloy.
| 2. Watertightness of broken aluminum doors and windows |
Since the opening fan (inside opening) of the plastic window is not flush with the frame and is recessed into the room, it tends to accumulate water (does not enter the room). It needs to drain through the drainage groove and no condensation occurs in the winter. The opening fan of the aluminum alloy with broken bridge is in the same plane as the frame, and it is not easy to collect water. However, due to its metal characteristics, condensation may occur in winter.
| 3, airtight aluminum doors and windows breaking performance |
The PVC profile of the plastic window is connected by welding, and there is no gap at the connection; while the aluminum window of the broken bridge is connected by bolts, the hermeticity of the plastic window is superior to that of the broken aluminum window.
| 4ã€Aluminum doors and windows insulation performance |
PVC profiles are the best insulation properties in the current profiles for doors and windows, the heat transfer coefficient is 1/357 of the steel, is 1/125 of the aluminum, the ratio of the heat transfer coefficient of the whole window of aluminum profiles and PVC profiles is 1.44 Times, that is, winter and summer energy loss is 1.44 times that of plastic steel windows.
| 5, broken bridge aluminum doors and windows lighting performance |
Since the projection size of the plastic window on the facade is larger than that of the aluminum window of the broken bridge, the light shielding area of ​​the frame sash is 10% larger than that of the aluminum window of the broken bridge. Therefore, the same hole size, the lighting performance of the plastic window is better than that of the broken bridge. Aluminum alloy window difference is about 10%.
| 6, sound insulation performance of broken aluminum doors and windows |
Due to the metal properties of aluminum alloys, its energy transmission performance is much higher than that of plastic steel windows, which includes acoustic energy and thermal energy. Therefore, the sound insulation of plastic steel windows is significantly better than that of aluminum alloy windows.
| 7ã€Aluminum doors and windows fire performance |
The fireproof performance of the plastic window is non-flammable, and the aluminum window of the broken bridge is not burned, so the fire resistance of the broken aluminum alloy is better than that of the plastic steel window.
| 8, broken bridge aluminum doors and windows on the issue of lightning protection and static electricity |
Aluminum alloy is a good electrical conductor. PVC plastic is a non-conductive insulator. When it is used in high-rise buildings (more than 30M for lightning protection, more than 45M for Category II, and more than 60m for Category III), it cannot solve the problem of side-to-side lightning protection. Therefore, in order to strengthen the anti-static problems of aluminum alloys, electrostatic spraying treatment is often adopted.
Summary: After reading so many different features on broken aluminum doors and windows, you can rest assured that you can choose to break the aluminum doors and windows. In fact, in general, the performance of broken aluminum doors and windows is very good, if you want to install This type of doors and windows must choose good construction quality businesses. After all, doors and windows are installed in three-point quality seven points. Finally, we wish everyone can buy the right doors and windows, if you want to see other information, please pay attention to this site information channel .
