Product Title

High Transparent Cast PMMA Acrylic Noise Barrier Sheet, Highway Bridge Railway Sound Insulation Barrier, UV Resistant Impact Resistant Transparent Acoustic Panel

Quick Overview 

Acrylic noise barrier (PMMA plexiglass barrier) is a premium transparent sound insulation panel widely applied for highway, viaduct, railway, bridge, residential community, factory and construction site noise control. Made of 100% virgin MMA cast acrylic sheet, it combines excellent sound reduction, ultra-high light transmittance, strong weather resistance and lightweight structure, solving the visual depression problem of traditional metal/cement noise walls. OEM size, thickness, color and filament reinforcement customization available, fully meet EN1793, ASTM, ISO9001, CE international standards.

Core Advantages

● Excellent Sound Insulation Performance Sound reduction index Rw: 32~37dB for 15–20mm standard thickness; thicker panels up to 40dB noise attenuation. Dense PMMA structure blocks traffic, mechanical and industrial noise effectively via mass isolation principle.

● Ultra High Light Transmission & Landscape Friendly Clear grade light transmittance ≥91%–93%, same clarity as float glass. No closed tunnel feeling for drivers; retain city, river and mountain landscape, perfect for urban scenic road projects.

● Superior Outdoor Weather & UV Resistance Integrated anti-UV stabilizer, long-term outdoor use less than 2% yellowing within 10 years. Resist rain, frost, high temperature, acid rain and vehicle exhaust corrosion, service life 10–15 years without frequent maintenance.

● Lightweight & Safe Structure Weight only 1/2 of same-thickness glass, greatly reduce steel frame load, cut foundation and support cost. Optional embedded polyamide filament reinforcement (FSR shard retention): fragments locked inside sheet if broken, no falling hazard for bridge overpasses.

● High Mechanical Stability & Easy Fabrication Tensile strength ≥70MPa, Vicat softening point ≥100℃. Support thermoforming, cold bending, polishing, drilling, cutting; match curved road/bridge radian perfectly. Smooth surface, anti-graffiti, easy wash clean.

● Customized & Eco-Friendly Clear, bronze, solar grey, matte anti-glare colors optional; full OEM size, thickness, printing bird-protection stripes. Non-toxic, low carbon production, recyclable PMMA material.

FAQ

Q1: What’s the difference between acrylic and PC polycarbonate noise barrier? 
A1: Acrylic (PMMA): Higher light transmittance, better surface gloss, lower long-term yellowing rate, more cost-effective for medium noise road/bridge. PC sheet has far stronger impact resistance, fit for stone-fall risk mountain highway. We supply both materials for customer selection. 
Q2: Is filament reinforced acrylic required for bridge projects? 
A2: Most EU, Southeast Asia bridge engineering standards require embedded polyamide filament; broken pieces will not drop onto road below, meet traffic safety regulation. 
Q3: Can acrylic barrier be bent to fit curved road? 
A3: Yes, cast acrylic supports thermoforming C-shaped arc panel to match road/bridge curvature, no visible stress crack after forming.
