During the process of choosing doors and windows, apart from the selection of material types (such as common aluminum alloy and thermal break aluminum), material brands, and opening methods (such as casement and sliding), many consumers are confused by the numerous models and series of thermal break aluminum.

During the sales process in the store, we often encounter consumers asking questions such as: What are the differences between the 60 series, 70 series and 80 series of the aluminum-clad doors and windows? How significant are these differences in terms of the functionality of the doors and windows? Which series is better to choose when doing home decoration… and so on. Today, our editor will introduce to you the differences among the aluminum-clad door and window models – the 60 series, 70 series, 80 series, 108 series, and so on:

Main Distinction

• Firstly, the differences in the series such as 60, 70, 80, and 108 lie in the width of the profile section, which are 6 centimeters, 7 centimeters, 8 centimeters, and 10.8 centimeters respectively. The wall thickness of the aluminum alloy profiles used is 1.4mm, 1.8mm, 2.0mm, and 2.2mm, etc.

• Due to the different widths, the 80 series uses the most materials, has better wind resistance performance, is also more sturdy, and of course, its cost performance is relatively high.

• Secondly, the larger the model number, the wider the corresponding window frame. This means that in the 60, 70 and 80 series, as well as the 108 series, the 108 series has the widest window frame. Therefore, it has more free space than the other series. Because the sealing strips and felt strips in the door and window frames rely on these spaces to ensure sufficient thickness.

• Of course, compared to the 60 and 70 series, the 108 series means it will occupy more window sill area, and the price is also more expensive! Therefore, when choosing the window model number in practice, one needs to comprehensively consider factors such as one’s own balcony and window sill area size, as well as the economic budget for door and window decoration. Try to choose the most cost-effective door and window products.

How to choose the common door and window series?

There are various models currently available in the market. How can one make the best choice?

To make an appropriate choice, the prerequisite is to have a relatively in-depth understanding of the characteristics and differences of each series of door and window products.

• 1、Different material cross-sectional widths:

As mentioned earlier, the cross-sectional width of the profiles in the 60 series of broken bridge aluminum is 6 cm, while that of the 70 series is 7 cm. The widths for other series can be derived in the same way. When installing windows on the countertop, they will occupy 6 cm and 7 cm of space respectively. In addition, the frame materials and window sash materials of the 60 series are narrower than those of the 70 series. The larger the number, the wider the material width.

• 2、The widths of the insulation strips are different:

The 60 series of broken bridge aluminum uses 2CM thick insulation strips, while the 70 series uses 2.5CM thick insulation strips. Other series may use double-layer insulation strips. The wider insulation strips perform better in terms of insulation than the narrower ones. Multi-chamber and multi-insulation strips offer better insulation and heat preservation coefficients than those with fewer chambers and fewer insulation strips.

• 3、The thickness of the glass is different:

The thickness of the insulating glass in the 60 series of broken bridge aluminum is 5 + 15A + 5, or 5 + 18A + 5. While the glass in the 70 series of broken bridge aluminum is 5 + 24A + 5 or 5 + 27A + 5. Therefore, the glass of the 70 series of broken bridge aluminum has better sound insulation than that of the 60 series. However, there is no absolute rule. It depends on the specific usage situation of the manufacturer.

• 4、The prices are different:

Although the material of the 70 series of broken-bridge aluminum is only 1 centimeter wider than that of the 60 series, don’t underestimate this 1 centimeter. The 70 series uses much more aluminum profiles than the 60 series, so its price is much higher than that of the 60 series of broken-bridge aluminum. For other series, the larger the number, the higher the price.

Overall, in fact, each series has the same basic function of doors and windows – to protect from wind and rain. There are differences in factors such as sound insulation and theft prevention. When making a choice, the main consideration is environmental factors. For example, residents living on higher floors, due to the wind pressure resistance performance and safety of the windows, it is recommended to choose the large number series. At the same time, price factors and window sill area factors should also be considered, and the most suitable aluminum alloy doors and windows series should be selected.
