How to choose the commonly used door and window series?

2025,04,11

There are various commonly used models on the market now. How to choose better?

If you want to choose, the premise is to have a deeper understanding of the characteristics and differences of the two series of door and window products.

Different material cross-sectional widths

The cross-sectional width of the profile of the 60 series of broken bridge aluminum is 6cm, and that of the 70 series is 7cm. By analogy, the windows installed on the countertop will occupy 6CM and 7CM. In addition, the frame materials, window sash materials, etc. of the 60 series are also narrower than those of the 70 series. The larger the number, the wider the material.

Different widths of thermal insulation strips

The 60 series of broken bridge aluminum commonly uses 2CM thermal insulation strips, while the 70 series of broken bridge aluminum commonly uses 2.5CM thermal insulation strips. Other series may use double-layer thermal insulation strips. The wider thermal insulation strips are better in thermal insulation than the narrower ones. More cavities and more insulation strips have better thermal insulation coefficients than fewer cavities and fewer insulation strips.

Different glass thickness

The insulating glass thickness of the 60 series of broken bridge aluminum is 5+15A+5, or 5+18A+5, while the glass of the 70 series of broken bridge aluminum is 5+24A+5 or 5+27A+5, so the glass of the 70 series of broken bridge aluminum is better than that of the 60 series in terms of sound insulation. However, there is no absolute, it depends on the specific manufacturer's use.

Different prices

Although the material of the 70 series of broken bridge aluminum is only 1 cm wider than that of the 60 series, don't underestimate this 1 cm. The amount of aluminum profiles used in the 70 series is much more than that of the 60 series, so the price is also much more expensive than that of the 60 series of broken bridge aluminum. For other series, the larger the number, the more expensive the price.

In general, the basic functions of doors and windows in each series are the same - to protect against wind and rain. There are differences in sound insulation and anti-theft coefficients. Environmental factors should be considered mainly during the selection process. For example, for residents living on higher floors, it is recommended to choose a large digital series for the sake of wind pressure resistance and safety of the windows. At the same time, price factors and window sill area factors should be considered to select the most suitable aluminum alloy door and window series.
