Aluminum foam plate a composite glass composite sound-absorbing sound insulation screen. Aluminum foam sound barrier is now commonly used in China, the cost per linear meter is about 2,250 yuan (8 mm thickness of aluminum foam, excluding the foundation). It has the following important characteristics and advantages:
(1) Aluminum foam sound-absorbing panels are directly exposed to the atmosphere, without the need for perforated panels and fillers, etc., and are easy to install. Aluminum foam acoustic panel is the world’s non-fiber acoustic material replacement products, will not be like glass wool and other easy to sinking agglomeration after the impact of acoustic performance, and will not be aging due to dust and microfiber dispersal of the atmospheric environment caused by secondary pollution.
(2) Aluminum foam sound barrier has stable acoustic performance, the average absorption coefficient is more than 0.64, noise reduction coefficient NRC0.75 or so, for the low-frequency-based traffic noise acoustic performance is good, 125Hz absorption coefficient of 0.52, 250 Hz absorption coefficient of 1.32, 500 Hz for 0.92, higher than some other commonly used acoustic materials, and in the rain and dust absorption, the absorption coefficient will not change. The sound absorption coefficient will not change, and the test report meets the acoustic requirements of road sound barriers.

(3) Aluminum foam acoustic panels can be sprayed into a variety of colors, and the acoustic performance is not affected.
(4) Aluminum foam acoustic panel can be washed as well as glass, and can achieve self-cleaning through natural rain, which will not affect the acoustic performance; after accumulation of ash, not only does it not affect the acoustic performance, but also improves the high-frequency acoustic performance.
(5)Aluminum foam has metal corresponding fire resistance, weather resistance, corrosion resistance, aging resistance, design service life of 20 years, broken or renewed aluminum foam panels can be recycled all.
(6) Aluminum foam acoustic panels compared to aluminum fiberboard has good anti-glare characteristics, especially at night and rainy days, can eliminate safe driving hazards.
