Superior thermal insulation performance: aluminum doors and windows of broken bridges are soft-bonded with inner and outer frames of thermal insulation profiles, and the frames are sealed in a 3 form of 1 rubber strips and double wool strips, which are tightly closed, have excellent air and water tightness, and have superior thermal insulation performance. The window sash adopts the hollow glass structure, which can effectively isolate the indoor and outdoor temperature, reduce the heating cost, and the energy saving effect is remarkable.
Sound insulation and noise prevention effect is good: through the use of different thickness of insulating glass and thermal insulation broken bridge aluminum profiles, broken bridge aluminum doors and windows can reduce the resonance effect of sound waves, to achieve sound insulation of more than 29 decibels, and some products can even reach 30 to 40 decibels, can effectively block noise, create a quiet living environment.
Waterproof function is powerful: the structural drainage system is designed by using the principle of pressure balance, the slope of the sliding design is stepped, the drainage port is set, the drainage is smooth, and the water tightness is good. At the same time, the broken bridge aluminum profile can realize the three sealing structure of doors and windows, reasonably separate the water vapor cavity, successfully realize the equal pressure balance of steam and water, and further improve the water tightness and air tightness of doors and windows.
Anti-theft, anti-loose: with a unique multi-point hardware locks, to ensure the stability and safety of the window in use.
Fire prevention function: aluminum alloy is a metal material, which will not burn and has a long fire resistance.
Good decorative effect: Broken bridge aluminum doors and windows have high gloss, beautiful and elegant decorative effect, and it is not easy to fade, not easy to fall off, and has a long service life. At the same time, aluminum alloy material is easy to process, can produce a variety of shapes and styles of doors and windows. Surface treatment methods are also diverse, such as spraying, fluorocarbon spraying, etc., to make the appearance of doors and windows more beautiful.
Strong weather resistance: Broken bridge aluminum doors and windows in the production process after anti-corrosion treatment, can be used for a long time in various climatic environments, not susceptible to corrosion and fading.
Convenient maintenance: when the aluminum doors and windows of the broken bridge are in the normal opening and closing state, the penetrating rainwater flows down to the outside along the tiny cracks between the heat insulation strip and the aluminum profile, without siltation or water storage, and the maintenance is simple.
