Transparent Noise Barrier | Polycarbonate Noise Barrier

A Transparent Noise Barrier, also known as a Polycarbonate Noise Barrier, is designed to create an effective sound shield between a noise source and sound-sensitive areas. These barriers help reduce the impact of noise generated by highways, busy roads, railways, industrial zones, HVAC systems, commercial complexes, and construction sites. They are widely used to protect residential communities, schools, hospitals, office buildings, parks, and public spaces from excessive noise.

Why Transparent Noise Barriers Are Effective

Transparent noise barriers offer a visually appealing and highly efficient solution to noise pollution. By using high-quality polycarbonate or acrylic materials, these barriers maintain clear visibility while effectively reducing sound transmission. They are especially beneficial in locations where maintaining scenic views is essential, such as residential areas, commercial zones, and urban landscapes.

Ecotone Systems – Advanced Metallic Noise Barriers with Transparent Elements

Ecotone Systems specializes in manufacturing, supplying, and installing premium metallic noise barriers with transparent sections. These barriers are engineered using galvanized aluminum or heavy-duty steel panels combined with durable polycarbonate or acrylic sheets. This combination forms a robust sound-insulating structure that not only blocks noise but also enhances aesthetic appeal by allowing clear visibility to the other side.

The barrier panels are carefully designed to overlap vertically using strong steel-profile studs, ensuring high structural strength and long-term performance. For enhanced acoustic efficiency, an absorbent crest can be added to increase noise reduction. Ecotone’s noise barriers can be designed as bi-absorbent panels and can also incorporate transparent sections depending on project requirements.

Key Benefits of Transparent Noise Barriers

Transparent noise barriers offer several advantages due to their lightweight, durable, and weather-resistant construction. Made using galvanized steel, aluminum, or stainless steel combined with polycarbonate or acrylic panels, they offer long service life and require minimal maintenance. Their flexible design allows horizontal or vertical installation, easy removal, and quick on-site assembly. These barriers also deliver excellent acoustic performance with STC 37+ and NRC 0.95+, making them suitable for heavy-noise environments. Their self-draining system and graffiti-resistant surface further enhance reliability in outdoor applications.

Constituents of the Noise Barrier System

The transparent noise barrier is designed using three essential components to ensure maximum acoustic efficiency. The absorbent face, positioned toward the noise source, consists of a multi-perforated metal layer that allows sound waves to pass through and disperse inside the absorbent material. This helps significantly reduce noise reflection and enhances overall sound absorption.

Inside the barrier, the sound insulation layer is usually made from high-density Rockwool. Its elastic and fibrous structure dissipates sound energy effectively, contributing to strong noise reduction performance. The reflective face, located behind the Rockwool, forms a sound chamber that bounces remaining sound waves back into the absorbent material, ensuring maximum noise attenuation.

Supporting the entire structure is a robust MS steel frame, hot-dip galvanized and finished with polyester powder coating for exceptional durability. These steel beams are engineered according to project-specific load requirements and anchored to the foundation using pre-installed concrete bases or galvanized steel bolts, ensuring superior stability and long-term performance.
