Performance of bridge broken aluminum:
1. Broken bridge aluminum doors and windows have good thermal
insulation. It adopts the soft combination of inner and outer frame of
thermal insulation profile. The frame adopts three sealing forms of one
rubber strip and two wool tops. It is closed tightly, with excellent air
and water tightness and excellent heat preservation performance; The
window sash adopts insulating glass structure, which makes the window
truly show excellent sound insulation, heat insulation, heat
preservation and function, and saves a lot of heating and cooling costs.
The heat transfer coefficient K value is less than 2.23-2.94w/2k. The
energy-saving effect is remarkable. The energy-saving cost in several
years is enough to make up for the earlier investment.
2. Waterproof function of bridge broken aluminum doors and windows.
According to the principle of pressure balance, a structured drainage
system is designed, and the sliding slope is designed as a ladder type.
The drainage outlet is set to ensure smooth drainage and good water
3. The broken bridge aluminum doors and windows should be protected from
condensation and frost. 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
