You get what you pay for, just like buying higher-quality products versus buying products with higher cost performance!
System doors and windows are a comprehensive organic combination of performance systems, requiring higher levels of water tightness, air tightness, wind resistance, mechanical strength, heat insulation, sound insulation, burglary resistance, sun shading, weather resistance, and operational feel, among other important functions. They also require the comprehensive results of equipment, profiles, accessories, glass, adhesives, and sealing components, all of which are indispensable, ultimately forming high-performance system doors and windows.
Characteristics of System Doors and Windows
Wind Resistance: Refers to the performance of external doors and windows not being damaged under wind pressure; for example, they are not prone to cracking, profile damage, glass breakage, adhesive failure, or hardware loosening hindering opening. There are a total of 9 levels, with system doors and windows averaging at level 6 standard (basic wind pressure coefficient of 0.8KN/㎡).
Air Tightness: Simply put, it is the ability of external doors and windows to prevent air infiltration when in the closed state. There are 8 levels in total, with system doors and windows averaging at level 6.
Water Tightness: The ability of doors and windows to prevent rainwater infiltration when closed in windy and rainy conditions. There are 6 levels in total, with system doors and windows averaging at level 4 standard.
Thermal Insulation: Also known as the K value in door and window professional terminology, system doors and windows should not be lower than level 3 standard, with a K value of below 0.8.
Sound Insulation: Also known as noise reduction, it refers to the ability to reduce the propagation of sound from the source to the listener. There are 6 levels in total, with system doors and windows not lower than level 3 standard.
Differences Between System Doors and Windows and Regular Doors and Windows
Not only focusing on product surface and glass quality, but also carefully examining the appearance of doors and windows, whether they are aesthetically pleasing, and whether they can withstand corrosion and wear are all factors to consider.
Well-made system doors and windows are very precise in workmanship, with smooth lines. During installation, there are no obvious gaps, good sealing performance, and smooth opening and closing.
Due to different application environments, strength should be considered, mainly in the selection of profile materials for doors and windows, whether they can withstand high pressure, whether the frame structure is tight, and whether the doors and windows can be tightly closed.
The company's technical department conducts strict testing and inspection on each component, comprehensively testing materials, performance, and quality. Each department cooperates very well, so problems are less likely to occur. System doors and windows are serialized and standardized products, and users can choose according to their needs.
In the use process, regular doors and windows may have relatively more problems, and stability may be poor. Regular doors and windows processing may not undergo more comprehensive and detailed testing. After all, you get what you pay for, just like buying higher-quality products versus buying products with higher cost performance!
