How about broken bridge aluminum doors and windows? You can take a closer look at the shortcomings
Broken bridge aluminum doors and windows refer to the glass and window mullions installed on balcony windows. Why do many people choose broken bridge aluminum doors and windows when choosing door and window building materials for new house decoration? It is not only beautiful and generous, but also has better functional effect.
How about broken bridge aluminum doors and windows? You can take a closer look at the shortcomings
Here are some disadvantages of broken bridge aluminum doors and windows
Everything has two aspects. Broken bridge aluminum doors and windows don't look perfect. For example, the heat resistance of broken bridge aluminum doors and windows is relatively poor, so safety accidents may occur when the lower ambient temperature rises, The insulation strips of broken aluminum doors and windows are made of PVC resin, which may soften and deform when the temperature rises.
Another reason is that the ventilation of the broken aluminum doors and windows is not very good. In summer, the weather is muggy. In winter, closing doors and windows may lead to hypoxia, and the angle of the window cannot be adjusted at will, which is relatively rigid. Moreover, the broken aluminum doors and windows are not easy to repair after being broken, and the maintenance cost is also very high.
Ordinary broken bridge aluminum doors and windows
1. Poor quality of insulating strip
Some enterprises use low-cost non structural materials. The thermal insulation doors and windows made of broken bridge aluminum profiles, coupled with the PVC insulation strip passing through the insulation strip, will cause the PVC insulation strip to become loose or even completely loose in the broken bridge aluminum profiles due to thermal expansion and contraction after actual installation and use. Disassembly will lead to the loosening and deformation of the window, thus damaging the air tightness and water tightness of the door and window, or causing the overall loosening and separation of the window.
2. Insufficient wall thickness
At present, in the engineering example of broken bridge aluminum doors and windows, many companies use aluminum profiles with different wall thickness, especially aluminum profiles with wall thickness less than 1.4mm as heat insulation broken bridge aluminum profiles. The concealment of this "covering the sky and the sea" is very strong. The owner of the broken bridge aluminum door and window project can only identify it before contour processing.
3. The process test is not enough
General door and window projects must undergo relevant performance tests conducted by strict national relevant performance testing institutions, and the obtained test report shall be used as the performance test report of finished doors and windows to show people. However, the test data of this raw material can only represent its material properties, and the properties of the final products produced through processing processes such as hot extrusion and cooling will change greatly.
4 change of constituent materials
Some broken bridge aluminum doors and windows companies have fully studied and mastered the PVC insulation strips. However, no matter what changes are made, they are not broken bridge aluminum doors and windows, but sold to consumers at the price of broken bridge aluminum doors and windows.
As for whether to use the broken bridge aluminum doors and windows, we should look at the quality and decide by ourselves.
