due to the different widths, the 8 series uses the most materials, which has better wind pressure resistance and is stronger. Of course, the cost performance is also relatively high.
1. The difference between the 8 series and the 12 series of broken-bridge aluminum doors and windows is not only in the model, although the material difference is 1 cm, but the material difference between the two models is great. First, the 6 series of broken-bridge aluminum means that the material width is 6 cm, the 7 series of broken-bridge aluminum means that the material width is 7 cm, and the wall thickness of the 6 series of broken-bridge aluminum doors and windows is only 1.4MM (national standard), while the wall thickness of the 7 series of broken-bridge aluminum is 1.
2. Secondly, the 8 series of broken-bridge aluminum doors and windows generally has three seals or six seals, while some brands of the 7 series of broken-bridge aluminum doors and windows have reached the design of ten seals. At present, Fengaluminum and Shide 8 series all have six seals, but Zhongwang has already had ten seals. Feng aluminum series 12 is a three-way seal design, and Shide broken bridge aluminum series 8 is already a six-way seal design.
3. The difference between the 8 series and the 12 series of broken-bridge aluminum doors and windows is mainly manifested in the wall thickness and sealing tape, and the material width is also different. Other aspects are not very different. This is a comparison of materials. In terms of sound insulation and heat preservation, of course, the 8 series of broken-bridge aluminum is better, but the price of the 8 series of broken-bridge aluminum is also much more expensive than that of the 12 series.
