Laminated tempered glass sound barrier is a widely used transparent noise insulation structure for transportation infrastructure. It consists of double-layer laminated safety glass, hot-dip galvanized steel or aluminum alloy frames, EPDM sealing strips and anti-rust fasteners.
Compared with PC sheet barriers, laminated glass features higher hardness, scratch resistance and stable light transmittance without yellowing after long-term outdoor exposure. It blocks traffic noise while retaining a wide transparent view, matching urban landscape design for highways, viaducts, light rails and residential roads.

Product Introduction
Laminated tempered glass sound barrier is a widely used transparent noise insulation structure for transportation infrastructure. It consists of double-layer laminated safety glass, hot-dip galvanized steel or aluminum alloy frames, EPDM sealing strips and anti-rust fasteners.
Compared with PC sheet barriers, laminated glass features higher hardness, scratch resistance and stable light transmittance without yellowing after long-term outdoor exposure. It blocks traffic noise while retaining a wide transparent view, matching urban landscape design for highways, viaducts, light rails and residential roads.
Advantages
● Super High Transparency & Non-Yellowing Clear light transmittance above 88%, no UV aging or discoloration, long-term consistent transparent effect.
● High Safety Laminated Glass Double-layer tempered laminated glass with PVB interlayer. When broken, fragments stick to the film without splashing, avoiding falling hazards for roads and bridges.
● Excellent Sound Insulation Performance High density glass material effectively insulates medium & high frequency vehicle noise, STC sound insulation value up to 30–38dB.
● Scratch & Abrasion Resistant Hard glass surface resists sand, dust and external scratch damage, much more durable than polycarbonate panels.
● Stable Weather Resistance Adaptable to -40℃ ~ +70℃ temperature range, waterproof, anti-corrosion, no deformation under long sunlight exposure.
● Fire Resistant & High Hardness Inorganic glass material with good flame retardant property, hard surface prevents surface dent and wear.
● Beautiful Landscape Effect Smooth glass surface with clean appearance, suitable for urban scenic roads, overpasses and landscape bridges.
● Standard Modular Installation Integrated frame structure, easy modular assembly, convenient transport, installation and later replacement.
