    How to choose the difference between 60 and 70 aluminum doors and windows?

    Broken bridge aluminum doors and windows have the characteristics of sound insulation, heat insulation, heat preservation, sealing, good daylighting and changeable styles. They are loved by consumers and are also the first choice for consumption. So there are many models of broken bridge aluminum doors and windows, such as 60 and 70, what is the difference, how to choose. The 60 series of broken bridge aluminum doors and windows actually refers to the window frame, and the same is true for 70 series. Of course, 70 series is more robust and wind resistant in terms of the width of the frame. Secondly, the wall thickness of 60 series bridge breaking profiles of regular manufacturers is 1.4mm, while that of 70 series is 1.8mm. The larger the frame, the more stable it is, and the thicker the wall is, the stronger it is

    How to choose and buy aluminum doors and windows

    The difference between the aluminum alloy doors and windows and the broken bridge aluminum doors and windows is that how to choose and buy the windows has the functions of ventilation, daylighting, sound insulation, heat preservation and waterproof. The earliest wooden windows are easy to crack, the iron windows are easy to rust, the plastic steel doors and windows are easy to deform, and the aluminum alloy doors and windows have fast heat conduction. Then the emergence of the broken bridge aluminum doors and windows will solve the above problems. Wooden windows and iron windows are not to be mentioned for the time being, because you can know the old buildings when you go to school or travel. Plastic steel windows are made of plastic materials, which will deform after a period of time, resulting in loose closing of windows. Thus the sealing and heat preservation effect is poor. Aluminum alloy doors and windows, due to the aluminum profile is not easy to deform, but

    How many colors are there in the aluminum doors and windows of liefan broken bridge

    Broken bridge aluminum doors and windows also known as "thermal insulation bridge broken aluminum alloy doors and windows", the role is to prevent indoor (outdoor) heat flow to the outside (inside). Broken bridge aluminum is called broken bridge because a heat insulation strip PA66 is added in the middle of the aluminum profile, that is, the aluminum profile (alloy) is disconnected from the middle, and the disconnected aluminum alloy is connected as a whole by using the heat insulation strip, so as to achieve the function of heat insulation and heat preservation. You will see many different colors of doors and windows in the market, that is, broken bridge aluminum doors and windows. The raw materials of broken bridge aluminum doors and windows purchased from aluminum profile manufacturers are only white, light champagne and deep champagne. Other colors are processed by powder spraying, which can make bridge broken aluminum

  •  What is the principle of Livan bridge breaking aluminum alloy and heat insulation bridge breaking aluminum alloy?

    What is the principle of Livan bridge breaking aluminum alloy and heat insulation bridge breaking aluminum alloy?

    The principle of heat insulation bridge breaking aluminum alloy is to insert heat insulation strip in the middle of aluminum profile to cut off the aluminum profile to form a broken bridge and effectively prevent heat conduction. The thermal conductivity of Lifan thermal insulation aluminum alloy doors and windows is 40-70% lower than that of non thermal insulation aluminum alloy doors and windows. ⊙ reduce heat conduction: the heat conduction coefficient of heat insulation bridge broken aluminum alloy profile is 1.8 ~ 3.5W / m2 · K, which is much lower than 140 ~ 170W / m2 · K of ordinary aluminum alloy profile; the heat conduction coefficient of insulating glass structure is 2.0 ~ 3.59w/m2 · K, which is much lower than 6.69 ~ 6.84w/m2.k of ordinary aluminum alloy profile
