Ultra-low energy consumption 92 series usually has the following advantages:

1. Excellent thermal insulation performance

Adoption of high-efficiency profiles: such as Shengda passive fire-resistant door and window system of ultra-wide section design, the basic width of 88mm, the external buckle aluminum increased by 4mm, a total of 92mm, all the external wall thickness of 3.0mm, exceeding the national standard class A design, the profile itself higher stiffness. Taking the lead in research and development of high heat preservation and high strength composite materials, instead of steel lining system, with excellent wind pressure resistance and heat preservation performance. Greenshield Zhongtian doors and windows choose ultra-new national standard 2.0mm wall thickness aluminum profiles, vertical isothermal design, reducing the overall energy consumption of doors and windows.

Multi-chamber structure design: like Shengda passive fire-resistant doors and windows system for the 7-chamber structure, Greenshield Zhongtian's products also have a 5-chamber structure, etc. Multi-chamber structure effectively increases the air insulation layer and reduces heat conduction.

Large-size heat-insulating strips: some products adopt 29mm large-size heat-insulating strips, multi-cavity structure, inner fins to isolate the cold and warm cavities, reduce heat exchange and improve the heat insulation and heat preservation performance.

High-performance glass configuration: Zhengjin Windows and Doors Star 92 series comes standard with 5G+10A+5G double-layer insulating tempered glass, with optional three-glass and two-cavity (e.g., 5G+12A+5G+15A+5G), and the whole window heat transfer coefficient, Uw≤1.2W/(㎡-K). Shengda passive fire-resistant doors and windows system installation glass thickness can be realized 50mm, glass embedded depth increased, to achieve lower heat transfer coefficient of glass edge line.

2. Good sealing performance

Multi-channel sealing design: three or more channel sealing design is commonly adopted, such as Zhengyin Windows and Doors Star 92 series adopts three channel sealing design (isopressure cavity + water-blocking adhesive strip + microcellular foam strip), with airtightness of 8 levels. Shengda passive fire-resistant doors and windows system pioneered the design of two sets of adhesive tape system, using soft and hard integrated TPV weldable adhesive tape or EPDM surface microfoam EPDM adhesive strips, the corners of the whole welding technology, adhesive tape installation without a break point, so that watertightness and airtightness is further improved.

High-quality sealing tape: Greenshield Zhongtian windows and doors adopt microwave vulcanization one-piece welding and equal pressure tape, one-piece molding at the corners, beautiful and waterproof. The conversion frame is sealed with double rubber strips to reduce the risk of wind and water leakage.

Hidden drainage system: Green Shield Zhongtian windows and doors and Jinggang Ya Tianfu series T103 casement windows and screens all use hidden drainage system, the drainage holes are vertically downward, effectively preventing water seepage and avoiding problems such as backflow of rainwater.

3. Excellent sound insulation performance

Combination of glass and profiles: Greenshield Zhongtian windows and doors are equipped with 4SG full-frequency noise-reducing glass, which combines with the multi-chamber structure and sealing design of the profiles to block noise layer by layer. Zhengjin windows and doors Star 92 series comes standard with 5G+10A+5G double-layer insulating tempered glass, optional three glass and two chambers, sound insulation ≥ 35dB.

Good sealing effect: Excellent sealing design not only blocks air infiltration, but also effectively reduces sound transmission into the room, creating a quiet living environment.

4. Reliable safety performance

Sturdy profiles and structures: such as Zhengjin doors and windows Star 92 series adopts Foshan T6063 virgin aluminum (wall thickness ≥ 1.8mm), with wind pressure resistance up to level 6, suitable for high-rise and coastal typhoon areas, as well as anti-drop design to protect the safety of buildings above 10 floors. Jingangya Tianfu series T103 casement window screen integrated window 5-cavity structure, large glass load-bearing higher, the frame is less prone to deformation, border and wall 7 support tendons, window installation is more stable and more solid.

High-quality hardware: Shengda passive fire-resistant doors and windows system generally use hardware all-inclusive structure, anti-theft hardware system, improve the sealing performance of the whole window while the safety performance of doors and windows greatly increased. Greenshield Zhongtian doors and windows selected Belgium Sobinko hardware, with no base handle, hidden hinges, anti-prying level multi-point locking system and professional guardrail, for home life escort.

5. Good lighting and ventilation performance

Reasonable glass configuration: some products use high-transparency glass, which can provide good lighting effect while ensuring heat insulation and soundproof performance, so that the room gets enough natural light.

Flexible opening mode: such as the internal opening and inverted design of Zhengyin Windows and Doors Star 92 series, the cold air slowly enters in the inverted mode, avoiding direct blowing and enhancing comfort, while the double internal opening design supports large angle opening, which is convenient for wiping the glass.
