Adopting heat insulation broken bridge aluminum profile and hollow glass, it has the functions of energy saving, sound insulation, noise protection, dustproof, waterproof and so on. The Broken Bridge aluminum doors and windows K value of heat-conduction coefficient is below 3W/㎡ · K, which reduces the heat loss by half compared with ordinary doors and windows, reduces the heating cost by about 30%, has a sound insulation of more than 29 decibels, and has good water tightness and air tightness, all up to the National A1 window Standard .
Bridge-cutoff aluminum alloy doors and windows how much do you know about the structure
Because the heat insulation strip in the middle supports the two layers of glass and connects them together, the strength of the whole support is greatly increased, and the bearing force is also greatly improved. It is precisely because of the heat barrier material of this layer that ordinary aluminum doors and windows can be called Bridge-cutoff aluminum alloy doors and windows.
It can be seen that the partition strip plays a vital role in the broken bridge doors and windows. Therefore, broken bridge aluminum of the brands use high-quality nylon strips, while some merchants use cheaper PVC plastic insulation strips to reduce costs, compared with the former, the latter is not only slightly inferior in sound insulation performance, but also has hard texture, easy aging and relatively short service life, this is why some broken bridge aluminum alloy doors and windows have good sound insulation while others are no different from ordinary aluminum doors and windows.
