Railway sound barrier is divided into pure sound insulation reflective railway sound barrier and composite railway sound barrier combining sound absorption and sound insulation. The latter is a more effective sound insulation method. It refers to the wall structure set beside the railway and highway to reduce the impact of traffic noise on nearby residents. Railway sound barrier is also called sound insulation wall. Insert a facility between the sound source and the receiver to make the sound wave propagation have a significant additional attenuation, thus reducing the noise impact in a certain area where the receiver is located. Such a facility is called the railway sound barrier. It is divided into traffic noise barrier, equipment noise attenuation noise barrier, industrial boundary noise barrier, highway and expressway where the most types of railway noise barriers are used. Most of the railway noise barriers are sound absorption and sound insulation hybrid products, which are characterized by targeted control of the generation and transmission characteristics of road noise. Transparent reflective sound insulation board is used in the middle of the railway sound barrier, which can effectively interrupt the transmission path of sound waves; At the same time, it also provides a wide visual environment for drivers and residents.

Plate thickness	0.6mm, 0.7mm, 0.8mm, 1.0mm (can be customized according to customer needs)
Molding thickness	60cm, 80cm, 100cm (can be customized according to customer needs)

1. Large sound insulation: average sound insulation 36dB 2. High sound absorption coefficient: average sound absorption coefficient 0.85 3. Economy: fabricated construction can improve work efficiency, shorten construction time, and save construction costs and labor costs 4. Characteristics: It has water resistance, heat resistance, UV resistance, and will not reduce the sound absorption quality of metal railway sound barrier due to the change of rain temperature. 5. Convenience: installed in parallel with other products, easy to maintain and replace 6. Fire prevention: Ultra-fine glass wool is used. Because of its high melting point and non-combustible, it fully meets the requirements of environmental protection and fire prevention specifications, and the fire prevention grade reaches Class A.
