Construction
Designed for mobility and durability
Sonic acoustic curtains are built to be installed, moved and re-hung across sites where rigid enclosures aren’t practical. The construction is designed to take repeated handling, weather exposure and rough site conditions.
- Outer layer: heavy-duty weatherproof reinforced vinyl
- Core: high-density acoustic barrier
- Inner face: absorptive layer for sound energy dissipation
- Edges: welded and reinforced for durability
- Eyelets: industrial-grade for hanging UV-stabilised and fire-resistant materials
Optional features
- Vision panels
- Access door inserts
- Ventilation zones
- Hook and loop joining systems
- Custom logos or branding
Testing & Compliance
Built to withstand harsh conditions
- UV resistance: certified.
- Weather resistance: validated for prolonged outdoor exposure. Independently tested to AS 1191-2002, AS/NZS ISO 717.1-2004 and AS ISO 354-2006
- Results from NATA-accredited laboratory testing available on request
Modular. Reusable. Easy to install.
Unlike permanent enclosures, Sonic acoustic curtains can be removed or reconfigured on short notice with minimal tools or infrastructure.
- Fast installation
- Minimal space requirements
- Can be folded, transported and reused
- Configurable around site-specific layouts and structures
