2, the scope of application is different: 55 series can be double sealed, 60 series can be triple sealed. Different materials, different windows. The 70 series glass is designed with six seals, and the thickness of the glass is different.
3. Different operation methods: 55 series broken bridge is a fan, and if yarn is needed, only 95 series broken bridge can be done, while 60 series broken bridge is a screen window combination, which can be opened inside and outside, and 70 series is also different in operation.
Extended data:
Generally speaking, the broken bridge aluminum door and window mine includes two main bodies: heat insulation broken bridge aluminum profile and insulating glass. Thermal insulation broken bridge aluminum is broken bridge aluminum, thermal insulation aluminum alloy and broken bridge aluminum alloy, which is an improvement to improve the thermal insulation performance of doors and windows on the basis of old aluminum alloy windows.
The principle of broken bridge aluminum alloy window is to use PA66 nylon to separate indoor and outdoor aluminum alloys and closely connect them into a whole, thus forming a new type of heat insulation aluminum profile. The door and window sash made in this way is equipped with insulating glass, hardware, invisible screen window, glass glue, foam glue, sealing strip and so on.
In addition, aluminum with wall thickness of 1.8mm is selected for Series 70, and aluminum with wall thickness of 1.4mm is selected for Series 60. Insulation effect, the firmness of 70 profile is much better than that of 60 profile, so pay attention to it when purchasing.
