The principle of heat-insulating broken bridge aluminum alloy is to penetrate the heat-insulating strip in the middle of the aluminum profile, and disconnect the aluminum profile to form a broken bridge, which can effectively prevent the conduction of heat. The thermal conductivity of heat-insulated aluminum alloy doors and windows is 40-70% lower than that of non-heat-insulated aluminum alloy doors and windows.

Advantages of Broken Bridge Aluminum:

1. Good thermal insulation properties. It adopts the soft combination of the inner and outer frames of thermal insulation profiles, and the frame adopts a three-sealing form of one rubber strip and two tops. The window sash adopts the hollow glass structure, which makes the window truly display sound insulation, heat insulation, heat preservation and excellent function, which saves a lot of heating and cooling costs. The heat transfer coefficient K value has been tested to 2.23&mdash. Below 2.94w/2K, the energy-saving effect is remarkable, and the energy-saving cost of several years is enough to make up for the initial investment.

2. Waterproof function. Using the principle of pressure balance, a structural drainage system is designed, and the slope is designed to be stepped down.

3. Prevents condensation and frost. The broken bridge aluminum profile can realize the three-layer sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of gas and water, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of clean and bright windows.

4. Anti-mosquito screen design. Invisible screen, which can be installed and used inside and outside, with anti-mosquito and flies, especially suitable for mosquito-rich areas in the north.

5. Anti-theft and anti-loosening device. Equipped with a unique multi-point hardware lock to ensure the stability and safety of the window in use.

6. Anti-noise sound insulation. The structure has been carefully designed with tight seams. According to the test results, the sound insulation of the air can reach 30-40db, which can ensure that residents within 50 meters on both sides of the expressway are not disturbed by noise, and the adjacent downtown can also ensure that the interior is quiet and warm.

7. Fireproof function. Aluminum alloy is a metal material and will not burn.

8. Sand and wind resistance. The inner frame straight material adopts hollow design, strong resistance to wind pressure deformation, and good anti-vibration effect. It can be used in high-rise buildings and civil residences, and can be designed with large-area windows and large lighting areas. The air tightness of this kind of window is better than that of any aluminum and plastic windows, and it can ensure that the indoor window sills and floors are free of dust in areas with heavy wind and sand.

9. High strength, no deformation, and maintenance-free. The broken bridge aluminum window has high tensile and shear strength and resistance to thermal deformation, and is strong and durable.

10. Broken bridge aluminum has various colors, which are very decorative. It can achieve different colors of indoor and outdoor surfaces of doors and windows, meet customers' preference for color effect, aesthetic needs of color gamut space, and meet the individual design requirements of architects. The aluminum profile adopts a streamlined design, and the shape is luxurious.

11. Green building materials, circular economy. In the production process, not only will no harmful materials be produced, but all materials can be recycled and reused.

12. There are many opening forms of broken bridge aluminum, which is comfortable and durable. There are flat-opening, inward-inclined, top-suspension, push-pull, flat-opening and inward-inclined and compound, etc., suitable for public buildings, residential quarters and municipal engineering.

High-quality hardware accessories are durable, user-friendly design of the operating handle, beautiful and comfortable, convenient and flexible to open, each use action has been tested, the number of fatigue tests is more than tens of thousands, the sliding is easy and silent, the mature and perfect door and window processing technology, high-precision procedures Control the machining center for production, and the quality is stable and guaranteed.
