Sound Barrier Walls
Designed primarily to reduce the transmission of noise through a wall, helping separate adjoining areas.
SOUND WALLS
Acoustic Wall Solutions
Specialist sound barrier and sound-absorbing wall systems for civil, commercial and industrial developments. Urbanscapes supplies and installs acoustic wall solutions tailored to project requirements.

Two Solutions. Different Acoustic Requirements.
Different environments require different approaches to noise control. Urbanscapes offers two acoustic wall systems designed to address different needs: Sound Barrier Walls, which help reduce noise transmission, and Sound Absorb Walls, designed to absorb sound energy and manage reflected noise.
Both systems feature modular panel construction, with product selection based on acoustic objectives, site conditions and engineering requirements.
SOUND BARRIER SYSTEMS
Sound Barrier Walls
Effective noise reduction with lightweight composite construction.
Sound Barrier Walls are designed to reduce noise transmission between adjoining areas. Constructed with cementitious or fibre-cement outer skins and a lightweight expanded polystyrene (EPS) core, these modular panels provide a practical solution for a range of commercial, industrial and infrastructure applications.
The modular panel format offers flexible configurations, a smooth exterior finish and practical installation options suited to different site and engineering requirements.
Key Features
- Cementitious or fibre-cement outer skins with an EPS core.
- Lightweight composite construction.
- Modular panel formats.
- Panel lengths up to 4,200 mm.
- Multiple panel heights and thicknesses.
- Configurations available for different wind regions, subject to engineering design.
Typical Applications
- Housing and residential developments.
- Aged-care facilities.
- Playgrounds and childcare environments.
- Bus stations and transport facilities.
- Petrol stations and drive-throughs.
- Aquatic centres.
- Commercial and industrial boundaries.
- Selected civil infrastructure projects.

SOUND ABSORPTION SYSTEMS
Sound Absorb Walls
Designed to absorb sound energy in noise-intensive environments.
Sound Absorb Walls are designed for environments where reflected noise and sound build-up require particular attention. The panels feature a perforated aluminium facing and a Rockwool/PET acoustic core. Sound enters through the perforated face and is absorbed within the core, helping manage reverberation and reflected noise.
Their lightweight yet robust construction makes them suitable for a range of commercial, industrial and infrastructure applications.
Key Features
- Perforated aluminium acoustic-facing surface.
- Non-perforated aluminium components.
- Rockwool/PET acoustic core, with 80% recycled content stated in the supplied specification sheet.
- Lightweight and robust construction.
- Panel lengths of 2,400, 3,000 and 4,000 mm.
- Standard panel height of 600 mm.
- Available thicknesses of 75 and 100 mm.
- Powder-coated finish.
- Surfmist listed as the standard colour, with custom colours subject to confirmation.
Typical Applications
- Road and rail corridors.
- Loading docks.
- Dyno rooms.
- Acoustic enclosures.
- HVAC systems, pool pumps and generators.
- Drive-through facilities.
- Cinemas and theatres.
- Water parks.
- Pubs, clubs and restaurants.
- Industrial and mechanical plant environments.
Technical Specifications
| Specification | 75 mm Panel | 100 mm Panel |
|---|---|---|
| Surface density | 8 kg/m² | 9.2 kg/m² |
| Sound insulation rating (Rw) | 25 dB | 27 dB |
| Noise Reduction Coefficient (NRC) | 0.90 | 0.95 |
| Panel lengths | 2,400 / 3,000 / 4,000 mm | 2,400 / 3,000 / 4,000 mm |
| Panel height | 600 mm | 600 mm |
Additional Product Information
- Moisture absorption: Less than 0.2% by volume under the test conditions stated in the specification sheet.
- Fire testing: The supplied sheet reports AS 1530.3 test results for the Rockwool core only. These results should not be interpreted as a fire rating for the complete wall system.
- Published product warranty: 10 years, subject to applicable terms and conditions.
- Published design life: 50+ years.
