what is Bridge-cutoff aluminum alloy doors and windows?
The Broken Bridge aluminium windows is an improved version to improve the thermal insulation performance of doors and windows on the basis of the old aluminium windows. The principle is to use PA66 nylon to separate and closely connect the indoor and outdoor aluminum alloy into a whole, forming a new heat insulation aluminum profile, according to different connection modes, it can be divided into strip type and glue injection type. Using this profile as doors and windows has superior heat insulation, which completely solves the fatal problems of fast conduction and heat dissipation of aluminum alloy and does not meet the requirements of energy saving, at the same time, some new structural coordination forms were adopted to completely solve the long-standing problem of "aluminium alloy sliding window seal is not strict.
Bridge-cutoff aluminum alloy doors and windows advantages
1. Reduce heat conduction
the insulation broken bridge aluminum alloy profile is adopted, and its heat-conduction coefficient is 1.8~3.5W/㎡ · k, which is much lower than that of ordinary aluminum alloy profile 140~170W/㎡ · k. With hollow glass structure, its heat-conduction coefficient is 2.0~3.59W/㎡ · k, which is much lower than that of ordinary aluminum alloy profiles 6.69~6.84 ㎡ · k, effectively reducing the heat conduction through doors and windows.
2. Prevent condensation
the temperature of the inner surface of the profile with heat insulation strip is close to the indoor temperature, which reduces the possibility that indoor moisture condenses on the profile surface due to saturation.
3. Energy saving
in winter, the window frame with heat insulation strip can reduce 1/3 of the lost heat through the window frame; In summer, if there is air conditioning, window frames with heat insulation strips can reduce energy loss more.
4. Protect the environment
through the application of heat insulation system, energy consumption can be reduced, and environmental radiation caused by air conditioning and heating can be reduced at the same time.

bridge-cutoff aluminum alloy doors and windows disadvantages
the wind is not good, the opening angle cannot be adjusted at will, and the broken bridge aluminum valgus window is not easy to repair, so the household life should choose broken bridge aluminum valgus window carefully. The thermal conductivity of woolen wool strips in the Broken Bridge aluminum profile is low, and the heat insulation effect is 1250 times better than that of other ordinary aluminum materials. With its excellent air tightness, it can keep the temperature difficult to distribute in extremely cold seasons.
The above is an introduction to what is Bridge-cutoff aluminum alloy doors and windows and the advantages and disadvantages of bridge-cutoff aluminum alloy doors and windows. Have you learned it?
