Several advantages of the aluminum doors and windows of the German liefan Bridge
Editor: liefan, January 12, 2020 11:00:01

All the doors and windows of the broken bridge in Germany are made of pure aluminum ingots,

The door and window materials of national standard A1 / t5237 are all of the world's leading technology.

It adopts compound ten seal, super high performance price ratio, 1:4 wall type thick cavity design, and the heat preservation property reaches (UF = 2.4)

Liefan doors and windows are specially designed for the northern area of the compound 10 channel sealed window, can be installed with two or three layers of insulating glass, can resist the climate of northern cold area, the sound insulation capacity is more than 36 dB.

The heat insulation strip is made of glass fiber nylon 66, with wind pressure strength of 5.0 MPa, which is safe and reliable, and has the performance of energy saving, sound insulation and heat insulation.

1. Heat preservation and heat insulation: the heat conduction coefficient of bridge broken aluminum doors and windows is 1.8 ~ 3.5W / m2 · K, which is much lower than that of ordinary aluminum alloy profiles (140 ~ 170W / m2 · K) due to the use of thermal insulation bridge broken aluminum alloy profiles

2.0 ~ 3.59w/m2 · K is much lower than that of ordinary aluminum alloy profiles (6.69 ~ 6.84w / m2 · K), which effectively reduces the heat conduction through doors and windows.

2. Prevent condensation: the temperature of the inner surface of profile with heat insulation strip is close to the indoor temperature, which reduces the possibility of indoor moisture condensation on the profile surface due to supersaturation.

3. Energy saving: in winter, the window frame with heat insulation strip can reduce 1 / 3 of the heat loss through the window frame; in summer, if there is air conditioning, the window frame with heat insulation strip can reduce the energy loss more

4. Environmental protection: through the application of thermal insulation system, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time. ⊙ beneficial to health: the heat exchange between human body and environment depends on indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of doors and windows to make it no less than 12 ~ 13 ℃, the most comfortable environment has been achieved.

5. Noise reduction: the hollow glass structure with different thickness and heat insulation bridge broken aluminum profile cavity structure can effectively reduce the resonance effect of sound wave, prevent the transmission of sound, and reduce the noise by more than 30dB.

6. After spraying, the aluminum window can produce different color after spraying and rolling.
