Broken bridge aluminum doors and windows

Broken bridge aluminium doors and windows, broken bridge aluminium is from the middle section of PA66 nylon insulation strip to connect to form a partition, in order to achieve the purpose of warm winter and cool summer. It has the functions of energy saving, sound insulation, noise prevention, dust prevention and waterproofing. The heat conduction coefficient K of broken bridge aluminium doors and windows is below 3W/K, which is half of the heat loss of ordinary doors and windows, 30% of the heating cost is reduced, and the sound insulation capacity is over 29 decibels. The water tightness and air tightness of broken bridge aluminium doors and windows are good, which meet the national A1 window standard.
