The system doors and windows are designed to meet the relevant requirements of customers, the environment, and policies. The system considers the water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, operating feel and other series of doors and windows. For important functions, on the premise of meeting the performance requirements of customers, other performances should be improved as much as possible. Then through the comprehensive consideration of equipment, profiles, structures, accessories, glass, glue, sealing, design, production, and installation, we provide systematic solutions to achieve various performance and quality indicators of doors and windows.
Observing its wind pressure resistance, the doors and windows of the system are not prone to cracking and damage under wind pressure. It is understood that the wind pressure resistance can be divided into nine levels, and the average value of the system doors and windows can reach six levels
Check the permeability of the isolated air when it is closed. This can be divided into eight levels. If it reaches level six or above, it belongs to the system doors and windows.
Check the performance of isolating rainwater leakage when it is tightly closed. This can be divided into six levels. If it reaches four levels or above, it belongs to the system doors and windows.
Check its thermal insulation, which is often referred to as the K value. Usually above the level 3 standard belongs to the system doors and windows
Check its sound insulation performance. This can be divided into six levels. If it reaches level 3 or above, it belongs to the system doors and windows.
Group angle collision angle technology is different
System doors and windows, whether it is a window frame or a sash, must use the glue injection process, whether it is the corner glue injection or the pin glue injection, rather than the simple collision angle process without glue.
The ordinary broken bridge aluminum window adopts the smashing process, that is, the aluminum alloy corner code is inserted into the profile cut at 45 degrees, and the precision machine is impacted and extruded to connect, and it is integrally formed, but no glue is injected; the system doors and windows are completed in the smashing process. There will be one more glue injection process later.
The connection process of the stile in the beam is different
Ordinary broken bridge aluminum doors and windows are connected by screws and steel sheets when connecting beams and columns, but all broken bridge aluminum windows use this process, while the system doors and windows use a pin glue injection process. It is a special glue filled between the corner code and the profile, the professional name is group corner glue, and the system doors and windows are pin glue injection process.
The above is the difference between the system doors and windows, which can be observed by consumers on the surface. The system doors and windows have to be filled with insulation cotton in the heat insulation strip cavity. Consumers generally cannot see this process in the finished windows. Yes, the essence of the system doors and windows is still broken bridge aluminum material, but the requirements for process assembly are different from ordinary broken bridge aluminum windows.
