The 65/70/80 mentioned here is not this, broken bridge aluminum doors and windows from 50 series, 55 series to 60 series, 65 series, even higher end 70 series Broken Bridge aluminium windows, 80 series. So what do these so-called 55, 65, 70 and 80 mean and represent?
In short, these numbers represent the width occupied by Broken Bridge aluminum window frames falling on the windowsill. For example, 55 series means that the width occupied by the window frame falling on the window sill is 5.5cm. Therefore, 60 is 6cm, 65 is 6.5cm, 70 is 7cm, and 80 is 8cm.
In fact, except for the width of the window frame, they are different in the wall thickness and sealing of the profile. Take the most common 60 series and 70 series Broken Bridge aluminium windows at present:
the difference between 60 series and 70 series Broken Bridge aluminium windows
i. Wall thickness
70 series of aluminum with a wall thickness of 1.8mm, 60 series of aluminum with a wall thickness of 1.4mm. Heat preservation effect, strong degree 70 profile is much better than 60 profile.
2. Glass
70 series profiles use 5 22 5 (two 5mm thick glass, the middle air layer is 22mm) hollow glass, 60 series profiles use 5 12 5 (two 5mm thick glass, the air layer in the middle is 12mm) hollow glass. In terms of sound insulation and cold insulation, 70 series Broken Bridge aluminium windows is much higher than 60 series.
