I. Product Performance
Excellent thermal insulation performance: Jumei’s断桥 aluminum windows and doors use specially made thermal break aluminum profiles. By enhancing nylon spacers, the aluminum profiles are divided into two parts, effectively blocking the heat conduction of aluminum and forming a ‘thermal break’ structure, greatly reducing the efficiency of heat transfer. In winter, it can reduce the loss of indoor heat through the window frame, keeping the indoor warm; in summer, it can block the entry of outdoor heat, reducing the energy consumption of indoor air conditioning, keeping the indoor temperature comfortable.
Superior sound insulation and noise reduction effects: With double-layered glass, using glass of different thicknesses and double-layered structures, the resonance effect of sound waves is effectively reduced, preventing the transmission of sound, significantly reducing the entry of external noise into the indoor environment, creating a quiet and comfortable living environment for you, reducing indoor noise by 30dB or more.
Good water resistance and air tightness: The windows and doors use a structural drainage system designed with the principle of pressure balance, with the sliding part adopting a stepped inclined design and equipped with drainage outlets, ensuring smooth drainage and excellent water tightness, effectively preventing rainwater leakage. At the same time, a three-seal form with one rubber strip and two felt strips is adopted, ensuring a tight and无缝 closure, good air tightness, all meeting the national A1 class window standard, effectively preventing dust and sand from entering the indoor environment.
Rugged, durable, and safe: The selected aluminum alloy profiles have high strength and strong wind pressure resistance, are not prone to deformation. Strictly following the national standard profile section wall thickness ensures that the windows and doors have good stability. In addition, effective anti-theft and anti-loosening devices are equipped, further enhancing home safety.
II. Product Specifications
Profile Thickness: Provides a variety of options, common thicknesses range from 1.4mm to 3.0mm. Thicker profiles such as 2.0mm, 3.0mm are suitable for buildings with higher strength and thermal insulation requirements and in harsh weather conditions; while the 1.4mm thickness profile meets national standards, can meet the needs of most ordinary buildings, ensuring performance while offering high cost-effectiveness.
Profile Width: The width range is generally between 50mm to 120mm. For example, the 55 series断桥 aluminum windows and doors, the profile section width is 55 millimeters, suitable for the installation of windows in ordinary residential buildings, the size is common and has strong adaptability; the 70 series profile section width is 70 millimeters, relatively wider, can better support the glass, enhancing the safety and stability of the windows, often used in building projects with higher requirements for window performance.
Thermal Break Height: Divided into large and small thermal breaks. The height of the large thermal break is generally 24mm or higher, with better thermal insulation and sound insulation effects; the small thermal break is usually around 18mm, more lightweight, suitable for occasions that do not require high strength but focus on cost and space utilization.
Glass Specifications: Different series come with different specifications of double-layered glass as standard. For example, the 55 series can use 5 + 12A + 5 double-layered glass, with a 12mm gap in the middle; the 70 series can use 5 + 22A + 5 double-layered glass, with a gap reaching 22mm, the larger the glass gap, the better the thermal insulation and sound insulation effects. Consumers can also choose thicker glass or glass with special functions (such as Low-E glass, which can effectively)
