Many people tend to equate broken bridge aluminum profiles with system doors and windows, and there are essential differences between the two. The broken bridge is only a thermal insulation structure form of the profile, while the system doors and windows are a complete performance system. The profile cavity, drainage path, locking point layout, and rubber strip section are all developed synchronously. The hardware is precisely matched with the profile groove, and after repeated opening and closing, water tightness aging testing, it ensures long-term stable use. Ordinary broken bridge assembled windows only use broken bridge profiles, and other accessories can be freely matched without a unified performance goal. After a period of use, problems such as air and water leakage, switch jamming, and sound insulation attenuation are prone to occur, which is also the core source of the difference in user experience between the two.
Doors and windows are customized products with dimensions that vary with the opening, and have a strong dependence on production accuracy and on-site installation. Insufficient processing accuracy or simplified installation process of the same system profile will significantly damage the overall window performance. The industry is promoting construction standardization, standardizing processes such as laying out and leveling, frame installation, structural waterproofing, weather resistant sealing, etc., to weaken the uncertainty caused by manual and arbitrary operations. With more rational consumption, the logic of purchasing has shifted from looking at individual product materials to verifying the testing reports, process details, and delivery plans of the entire system. This shift in consumer awareness is also accelerating the elimination of low-quality assembly capacity in the industry and promoting its development towards quality.
