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 bigger the frame is, the more stable it is. The thicker the wall is, the more durable it is and the longer its service life is.
Secondly, the frame of series 60 is a little narrower, so the spacing of double-layer insulating glass used in 60 series is different from that of 70 series. For example, the 60 series of liefan doors and windows is 5mm + 18a + 5mm, and 18a is the space between air layers of double-layer glass. The 70 series liefan adopts 5 + 22a + 5mm, the larger the space distance, the better the sound insulation, heat preservation and sealing effect, and of course, there is a larger space. However, 22a is the best service distance after testing, because if the glass exceeds 23a, resonance will occur, which will affect the glass life.
So how to choose 60 and 70 series bridge broken aluminum doors and windows? You can choose according to your own housing situation. If you live in noisy places near the road or live in high-rise buildings, you can choose a larger model. If you live in a place with low floors and no obvious noise, then 60 series can meet the needs of sound insulation, thermal insulation and sealing.
