The difference between “broken bridge teeth” and “no teeth” of aluminum alloy doors and windows

  1. What is broken bridge and tooth opening?
    “Broken bridge and open teeth” refers to the manufacturing process of aluminum alloy doors and windows, by opening one or more air gaps after surface treatment of the aluminum material, and setting certain heat insulation strips at the air gaps, aiming to reduce the surface contact of doors and windows. The cold and heat conduction effectively improves the thermal insulation performance and thermal insulation performance of doors and windows.
  2. What is open teeth?
    In contrast, “no teeth” means that the aluminum alloy material of the doors and windows is not processed, and the structure of the doors and windows is the same as that of traditional doors and windows, also known as “casement doors and windows.”
  3. The difference between the two methods
    From the perspective of thermal insulation design, “Broken Bridge Open Teeth” takes advantage of the discontinuity of thermal conductivity to divide the outside and inside of the aluminum alloy doors and windows into two independent sections to achieve better thermal insulation effect; without open teeth The design lacks auxiliary designs such as heat insulation strips, and the heat insulation performance is poor.
    Judging from the appearance of doors and windows, “broken bridge and open-tooth” doors and windows have less air gaps and are more visually beautiful; doors and windows without open teeth have no air gaps and have a more uniform appearance.
    From the perspective of manufacturing cost, “broken bridge and open-tooth” doors and windows require more manufacturing processes, so the cost is higher than “no-tooth” doors and windows.
  4. Advantages, Disadvantages and Usage Scenarios of Broken Bridge Teeth
  5. It has strong thermal insulation ability, which can effectively reduce the surface temperature of doors and windows and improve indoor comfort.
  6. Can reduce energy consumption and save energy.
  7. It has good air-tightness and can increase the sealing performance of doors and windows.
  8. It has good drainage performance and can effectively prevent water vapor from condensing.
  9. The manufacturing cost is high and the price is relatively expensive.
  10. It is difficult to maintain and difficult to build.
  11. The thermal insulation effect is related to the size of the air gap, and products from different manufacturers vary greatly.
    scenes to be used:
  12. Suitable for places with low winter temperatures in northern areas.
  13. Suitable for high-rise buildings, rooms with high floors and poor lighting.
  14. Suitable for occasions requiring good sound insulation and evaporation prevention.
