Huashuaite acrylic sound insulation sheets are featured in high quality, safety and reliability. The weight noise reduction DLR of a 15 mm thickness sheet is 30 dB, and a 20 mm thick sheet can reach 33 dB. What’s even more outstanding of Huashuaite sheets is that the reinforced sheets improve the impact resistance of the noise barriers. After an accidental impact, the sheets do not shatter upon breaking, which effectively protect pedestrians. As a result, these sheets are the best choice for elevated sound insulation systems in elevated roads of cities.
