Broken bridge thermal insulation aluminum door and window is also called broken bridge aluminum, thermal insulation aluminum alloy, and broken bridge aluminum alloy. Both sides are made of aluminum, and the middle is made of plastic profile cavity as thermal insulation material. This innovative structural design takes into account the advantages of both plastic and aluminum alloy materials, while meeting various requirements for decorative effects, door and window strength, and aging resistance.


The principle of Broken bridge thermal insulation aluminum alloy is to insert a thermal insulation strip in the middle of the aluminum profile to break the aluminum profile to form a broken bridge, which effectively prevents the conduction of heat. The thermal conductivity of insulated aluminum alloy profile doors and windows is 40-70% lower than that of non-insulated aluminum alloy profile doors and windows. Broken bridge aluminum is made of door and window frame fans, equipped with insulating glass, hardware, screens, glass glue, styrofoam, sealing strips, etc., and the door windows processed in this way are called broken bridge insulated aluminum doors and windows profile.

  Analysis of the advantages of thermal insulation aluminum for broken bridges:

  1. Broken bridge thermal insulation aluminum has good thermal insulation. The inner and outer frames of the heat insulation profile are softly combined, and the frame is sealed with EPDM tape, which is tightly closed, has excellent air and watertight performance, and has superior thermal insulation performance; the window sash adopts hollow glass structure, so that the window truly shows sound insulation and insulation. It has excellent heat, heat preservation and functions, and saves a lot of heating and cooling costs. The heat transfer coefficient K value is tested to be below 2.23—2.94w/2K. The energy saving effect is significant. The energy saving cost of several years is enough to make up for the initial investment.

  2. The thermal insulation aluminum waterproof function of the broken bridge. Utilizing the principle of pressure balance, a structural drainage system is designed with drainage outlets for smooth drainage and good water tightness.

3. The thermal insulation aluminum of the broken bridge prevents condensation and frost. Broken bridge aluminum profiles can achieve three-way sealing structure for doors and windows, and most of them can even achieve 8 sealings, reasonably separate the water vapor cavity, successfully achieve equal pressure balance of air and water, significantly improve the water tightness and air tightness of doors and windows, and achieve clean and bright windows. Effect.

  4. Design of thermal insulation aluminum mosquito screen window for broken bridge. The invisible screen window can be installed and used inside and outside. It is anti-mosquito and flies, especially suitable for mosquito-prone areas in the north. You can also choose anti-theft screens with anti-theft function.

  5. Thermal insulation aluminum anti-theft and anti-loose device for broken bridge. Equipped with unique multi-point hardware locks to ensure the stability and safety of the aluminium door and window in use.

  6. Broken bridge thermal insulation aluminum anti-noise and sound insulation. The structure has been carefully designed and the joints are tight. As a result of the test, the air sound insulation can reach 30-40db, which can ensure that residents within 50 meters on both sides of the expressway will not be disturbed by noise, and the neighboring downtown can also ensure that the interior is quiet and warm.

  7. The thermal insulation aluminum fireproof function of the broken bridge. Aluminum profile is a metal material and will not burn.

  8. The thermal insulation aluminum of the broken bridge is sand-proof and wind-resistant. The straight material of the inner frame adopts a hollow design, which has strong resistance to wind pressure and deformation, and has a good anti-vibration effect. It can be used in high-rise buildings and residential buildings. Large-area windows can be designed with large lighting area. The air-tightness of this type of window is better than any aluminum door and window or plastic windows. It can ensure that indoor windowsills and floors are dust-free in areas with heavy sandstorms.

  9. The thermal insulation aluminum of the broken bridge has high strength and no shape, maintenance-free. Broken bridge aluminum door and window has high tensile and shear strength and resistance to thermal deformation, strong and durable. Broken bridge aluminum profile is not easy to be corroded by acid and alkali, is not easy to turn yellow and fade, and almost does not need maintenance.

  10. Broken bridge heat-insulating aluminum has various colors and is very decorative. Different colors of indoor and outdoor surfaces of aluminium door and window profile can be achieved, meeting customers' preference for color effect, aesthetic needs of color gamut, and meeting the individual design requirements of architects. The aluminum profile adopts streamlined design with luxurious style.

  11. Broken bridge thermal insulation aluminum and aluminum green building materials, circular economy. Broken bridge aluminum doors and windows not only produce no harmful materials during the production process, but all materials can be recycled and reused. They are green building materials and environmentally friendly products, which are in line with the sustainable development of mankind.

  12. The thermal insulation aluminum of the broken bridge has many opening forms, which is comfortable and durable. There are flat opening, inward tilting, top suspension, push-pull, flat opening and inward tilting combined type, etc., suitable for public buildings, residential areas and municipal projects; high-quality hardware accessories are durable, the operating handle is humanized design, beautiful and comfortable, and easy to open Flexible, every use action has been tested, the number of fatigue tests has reached tens of thousands of times, sliding is easy and silent, mature and complete door and window processing technology, high-precision program control processing center for production, quality is stable and guaranteed.
