2. The broken aluminum doors and windows have good sound insulation effect: the structure is carefully designed and the joints are tight. The test results show that the sound insulation capacity is 30db.
3. Impact resistance of broken-bridge aluminum doors and windows: Because the outer surface of broken-bridge aluminum-plastic composite profile is broken-bridge aluminum alloy, it is more impact-resistant than plastic-steel window profile.
Advanced structure:
1. Broken bridge aluminum alloy doors and windows are the most advanced aluminum alloy doors and windows. It is the fifth generation of new thermal insulation and energy-saving doors and windows after wooden windows, iron windows, plastic steel doors and windows and ordinary colored aluminum alloy doors and windows. Its surface can be painted with various colors.
2. The structure of broken bridge colored aluminum alloy doors and windows combines the environmental protection of wooden windows, the firmness and safety of iron windows and steel windows. The thermal insulation and energy saving of plastic steel doors and windows are composed of two different sections through energy-saving heat insulation strips, also called nylon strips.
Its main function is to break the intermediate heat transfer and prevent the hot and cold heat transfer from being too fast or too slow. Its structure is more complicated than ordinary aluminum doors and windows, and its cost is higher. Ordinary colored aluminum does not have heat insulation strips, nor does it preserve heat and save energy. It is just attached to the surface.
