Building energy efficiency standards are getting higher and higher. You will find that many aluminum alloy doors and windows do not meet the energy efficiency standards. Why? Because you may have used non-system doors and windows. Only good system doors and windows can meet higher standards of energy-saving requirements. Of course, there are still many people who do not understand the difference between system doors and windows and non-system doors and windows. Today, I will take you to learn more about the difference between system doors and windows and ordinary doors and windows!
1. The concept of system doors and windows
The core features of the five products of system doors and windows: systematic design, high heat insulation profiles, standard material formulas, high-quality hardware systems, and rigorous production processes.
The system doors and windows adopt an overall systematic solution, and a series of important performances such as air tightness, water tightness, wind pressure resistance, heat insulation, sound insulation, anti-theft, weather resistance, and operating feel need to be considered. According to the requirements of the overall solution, design, manufacture, and install the products, and realize the promised performance and quality indicators in actual use.
2. the difference between the system doors and windows and ordinary doors and windows configuration
Door and window companies have gradually mastered the technology and principles of system doors and windows through research and learning. The performance and quality of ordinary doors and windows have been improved to a certain extent, but due to market distribution and price restrictions, ordinary doors and windows have not reached the European system door and window configuration and performance. Compared with glass curtain walls, the main materials, hardware, accessories, rubber strips, components, etc. of door and window materials are various. There are dozens of types of materials for a complete door and window, and there is a lot of room for selection and reduction. This is also the reason for the large gap in the price of the same type of window. The following construction details are illustrated.
The strength and sealing of the corners of aluminum alloy doors and windows processing is very important, which determines the splicing strength and waterproof degree of doors and windows. The traditional cornering process of ordinary doors and windows uses the connection form of extruded aluminum corner code + hit corner, and then squeeze the corner Sealant is applied to the edge of the knife, but the aluminum profile joints that really need to be sealed have no sealant. Rain water will enter the inside of the doors and windows through the joint capillary seams. This process is not easy to ensure the compactness of the corners and the sealing of the joints.
Sealing strips play a very important role in the water tightness and air tightness of doors and windows. In this regard, there is also a big difference between ordinary doors and windows and system doors and windows. Generally, the rubber strips of the door and window frame fans and the pressed glass are often disconnected at the corners. Due to the thermal expansion and the cold shrinking of the rubber strips, a hole is actually formed, which causes the problem of water leakage and air leakage. The corners of the glue strips of the system doors and windows are continuous, and the break point is at the middle position of the upper part where water is least likely to enter. It is difficult to bend a thick glue strip at 90 degrees, and the L-shaped glue corner connection is used to fundamentally solve the problem of water seepage.
In terms of stability and performance, the system doors and windows have their own independent technical department, which will conduct strict tests and inspections on the components of the system doors and windows. Therefore, the various components are very well matched and are not prone to failure, which is what we often say Good stability.
In terms of after-sales service, the warranty period of system doors and windows is longer than that of ordinary doors and windows. In addition to the engineering warranty of the door and window unit, the quality assurance of the system doors and windows also includes the system company’s product warranty.
