1. The broken bridge aluminum has good thermal insulation. The inner and outer frames of thermal insulation profiles are combined with softness. The frame is sealed tightly with one rubber strip and two wool strips. It has excellent air tightness and water tightness and excellent heat preservation performance. The window sash adopts hollow glass structure, which makes the window truly show excellent sound insulation, heat insulation, heat preservation and function, saving a lot of heating and cooling costs The heat coefficient K value is less than 2.23-2.94w/m2 · K. The energy-saving effect is remarkable, and the energy-saving cost in several years is enough to make up for the previous investment.

3. Anti condensation and frosting of bridge broken aluminum. The bridge breaking aluminum profile can realize the three-way sealing structure of doors and windows, reasonably separate the water vapor chamber, successfully realize the gas water isobaric balance, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of clean and bright windows.

4. The design of the anti mosquito screen window of the broken bridge. Invisible screen window can be installed and used inside and outside. It has the effect of anti mosquito and fly.

5. Anti theft and anti loosing device for bridge breaking aluminum. Equipped with unique multi-point hardware lock to ensure the stability and safety of windows in use.

⒍The bridge breaking aluminum has good sound insulation performance.. Its structure has been carefully designed and the joints are tight. The test results show that the sound insulation of the air reaches 30-40db, which can ensure that the residents within 50 meters on both sides of the expressway are not disturbed by noise, and the surrounding downtown can also ensure the indoor quiet and warm.
