1. Bridge aluminum 70 , 80, and 90 have certain differences in border width, indicating three widths of 7 cm, 8 cm, and 9 cm respectively. In addition, wall thickness, usage area, hardware type, and production technology are also different. Therefore, during the purchase process, you need to make a choice based on your actual needs.
2. For ordinary residential windows, 70 broken aluminum bridges are enough. The 70 broken bridge aluminum windows are very effective in terms of the strength of the profile and the waterproofing, sound insulation, and heat insulation of the entire window, and are very cost-effective. The standard glass of broken bridge aluminum alloy doors and windows is double-layer insulating glass. The middle interval of double-layer insulating glass is very large and the sound insulation is very good. Is it necessary to choose triple-layer glass broken bridge aluminum alloy windows? I have heard many misunderstandings from property owners. Is the sound insulation of triple-layer glass better than the sound insulation of double-layer hollow glass? The answer is that there is not much difference in sound insulation between the two. On the contrary, the sound insulation effect of double-layer insulating glass is better than that of triple-layer glass. But what are the advantages of triple-layer glass? The thermal insulation performance of three-layer glass broken bridge aluminum windows is better than that of double-layer insulated glass broken bridge aluminum windows. In short, the sound insulation of double-layer is better than double-layer, and the thermal insulation of double-layer glass is better than double-layer.
3 and 80 series profiles have a cross-section width of 8 cm, and the wall thickness of the magnesium-aluminum alloy profiles used is 1.4mm. Due to the different widths, the 80 series uses the most materials, has good wind pressure performance and is strong. Of course, the corresponding price will also be higher. The lining material used in the 80 series is slightly smaller and not resistant to wind pressure. The 80 series is a series of profiles with a high yield rate, which is particularly suitable for use in southern areas such as on-site, affordable housing, and construction site board houses. The 88 series is suitable for ordinary residential areas, office buildings, etc., and is suitable for northerly areas.
4. The integration of the 90 series broken bridge aluminum alloy diamond mesh means that the window screen and the window are integrated, which does not necessarily mean It’s the system window. System window refers to the overall frame of the window. According to the provided dimensions, the broken bridge aluminum material is formed in one piece when leaving the factory, and is called a system window. 90 broken bridge aluminum is very good, but ordinary broken bridge aluminum is only 50~70mm thick. Thicker broken bridge aluminum means a thicker layer of air between the glass and the glass. In this way, the energy-saving insulation effect can be improved, and the sound insulation effect will be more obvious.
5. Since the doors and windows need to be opened, they are thinner than the walls, and there are stickers on the parts that can be opened, etc., it has become a bottleneck for the overall sound insulation. First of all, 80% of doors and windows are made of glass. Ordinary glass and insulated glass have low sound insulation efficiency due to the permeability of sound waves, the sound wave matching effect of ordinary insulated glass, and the resonance valley property. Therefore, insulated glass will ignore the sound insulation and sound insulation effects, and vacuum glass will not be soundproof. Generally speaking, the insulation volume of vacuum glass is worse than that of insulating glass. The insulation volume of ordinary insulating glass is about 10-12 decibels, and the insulation volume of ordinary plastic doors and windows is about 5-7 decibels.
