Sound Barrier/ Sound Barrier Wall/ Sound Barrier Fence

Sound Barrier/ Sound Barrier Wall/ Sound Barrier Fence   Sound barrier (also called sound barrierwall, sound berm, sound barrier fence or acoustical barrier) is an exterior structure designed to protect sensitive land uses from noise pollution. Noise barriers are the most effective method of mitigating roadway, raolway, and industrial noise sources-- other than cessation of the source activity or use of source controls.     Technical reference of Sound Barrier    Impact strength: 850J/m ,the impact strength of solid PC sheets is 250 times that of glass, 20-30 times of PMMA sheet .
Light transmission: 80%-90% for different thickness of clear color  UV resistance:with our 50μm thickness UV layer ,the sheet can filter 99% ultraviolet radiation in sunlight
