Transparent Noise Barrier | Polycarbonate Noise Barrier

Transparent Noise Barrier / Polycarbonate Noise Barrier is normally used to place a sound barrier between a noise source and a target population.

A transparent noise barrier is an effective means to reduce the noise impact from sound sources affecting sound-sensitive receivers. Common sound sources include roads, highways, railways, retail and big-box developments, Mechanical & HVAC equipment, construction sites, etc. Receivers may include homes or apartments, schools, hospitals, office buildings, or even public parks. When noise becomes an issue between such sources and receivers, the use of sound barriers may be an ideal solution.

Metallic noise barrier with transparent element (metallic + polycarbonate or Acrylic)

Ecotone manufactures supplies and installs different types of metallic noise barriers to combat noise pollution coming from linear infrastructures (roads and railways, etc.).

Our Metal noise barrier with the transparent elements are made of galvanized aluminum or steel panels in between polycarbonate or acrylic sheets, that make up a sound-proof casing inside them along with aesthetic properties, and being transparent allows people to view the sceneries of another side. The panels overlap vertically between studs made from steel profiles.

The addition of an absorbent crest increases the acoustic performance. The barriers can be bi-absorbent and can include transparent parts.

Features of transparent noise barrier:

1.  Lightweight
2. Durable
3. Galvanized, aluminum, or stainless steel along with polycarbonate / acrylic sheet
4. Two, four, or five-inch thicknesses
5. Easy installation and removal
6. Horizontal or vertical installation
7. Self-draining
8. Maximum acoustical performance
9. All products independently tested (STC 37 above, NRC 0.95 above)
10. Weather-resistant11. Graffiti resistant12. Different colors selection


ABSORBENT FACE : oriented to the focus of noise: The absorbing face is a multi-perforated metallic element. The design of the perforations allows the sound wave to enter the panel and being scattered into the absorbent material.

SOUND INSULATION: Rockwool achieves a reduction in noise level due to its fibrous and elastic nature, which dissipates the energy of sound waves that penetrate them.

REFLECTIVE FACE: The reflective face leaves a space with Rockwool creating an acoustic chamber so that the sound waves reflect on it into the absorbent material.

Supporting structure: consists of MS Steel beams hot-dip galvanized and painted with polyester powder paint. The profiles are conveniently sized and arranged with a distance inter-axis depending on structural requirements. The beams are placed in holes already made in the concrete or they have a base plate anchored to the foundation by galvanized steel screws.
