First, let’s identify exactly what the five key performance levels of system windows and doors are. Now, let’s all take a closer look at them together.

　　(1) Wind-pressure resistance: Refers to the ability of exterior doors and windows to remain undamaged under the influence of wind pressure. For example, this includes resistance to cracks that don't easily break, damage to structural steel, glass breakage, adhesive failure, and loosening or malfunctioning hardware that could obstruct opening. There are a total of 9 levels in this classification; on average, system windows and doors achieve Level 6 (the Meimen 98 series meets the international high standard of Level 9).

　　(2) Confidential Performance: Simply put, under the condition that exterior doors and windows are properly closed, the ability to prevent air infiltration is graded into 8 levels. The average performance of system windows and doors reaches Level 6, while imported system windows and doors achieve an even higher level.

　　(3) Watertight Performance: Under normal closed conditions, the ability of doors and windows to prevent rainwater penetration is graded into six levels. The average performance of system windows and doors reaches Level 4.

　　(4) Thermal performance: This refers to the K-value mentioned in window and door technical terminology. System windows and doors must meet at least Grade 3 standards (the Meiwen 98 series achieves Grade 7, with a K-value of 1.2).

　　(5) Sound Insulation Performance: Also known as soundproofing or noise reduction, this refers to the ability to attenuate sound transmission from the source to the listener. It is categorized into six levels, with system doors and windows meeting at least Level 3 standards. (The U.S. door and window 98 series will meet Level 4 standards; glass configurations will be enhanced to improve sound insulation, and we hope for a corresponding increase in performance.)

　　What are the advantages of system windows and doors?

　　1. System windows and doors offer excellent thermal insulation performance: These windows truly feature soundproofing, heat insulation, and thermal preservation functions, which can significantly reduce cooling and heating costs. The energy savings over several years can easily offset the initial investment.

　　2. Excellent waterproof performance: Utilizing the principle of pressure balance, the structural drainage system and drainage openings are designed for smooth and efficient water discharge.

　　3. Anti-theft and anti-loosening device: A unique multi-capture feature ensures the window remains sturdy and secure during use.

　　4. Frost and Condensation Prevention: The steel used in system doors and windows enables three types of sealing structures, significantly enhancing the water tightness and air tightness of doors and windows and achieving a bright, clear window appearance.

　　5. Noise prevention and sound insulation: The structural design is ingenious and the joints are tightly sealed. Experimental results show that the sound insulation reaches 35–45 dB, ensuring that the interior remains free from noise disturbance and maintaining a warm indoor environment.

　　6. High strength and stability of doors and windows: System window and door systems exhibit high tensile, shear, and deformation resistance, ensuring durable and long-lasting performance. Foreign research on system windows shows that “the average actual service life of system windows is 15 to 30 years, whereas the actual service life of conventional windows is only 5 to 15 years.” This clearly highlights the significant difference between system windows and conventional windows.

　　7. Strong wind resistance and excellent seismic performance: Suitable for high-rise buildings and residential homes, this product allows for wide-window designs with large daylighting areas. Its airtightness surpasses that of any other window type, ensuring that indoor spaces remain dust-free even in windy and sandy environments.

　　8. It features multiple opening methods and is both comfortable and durable. It’s suitable for public buildings, residential communities, and municipal projects. First, the hardware accessories are highly durable, and the handle boasts a user-friendly design that is both aesthetically pleasing and comfortable, making it easy and flexible to open. Upon inspection, the sliding action is smooth and effortless. The door and window manufacturing process is mature and well-established, produced by highly precise CNC machining centers, ensuring stable and reliable quality.
