- Suitable for both industrial and private use
- Minimal maintenance
- Rigid, exceptionally durable steel structure
Technical description
A steel acoustic fence is an engineered element for reducing outdoor noise. It is designed to act as a high-mass acoustic barrier that limits the transmission of sound waves between the noise source and the protected area.
The system is based on a rigid steel shell combined with an internal acoustic core, usually stone wool (ROCKWOOL), which makes it possible to combine sound insulation with sound absorption on the inner side of the element.
The element works mainly through:
- Increased mass to block sound transmission (Transmission Loss)
- Reduced noise penetration through the structure
- Absorption of sound energy on the absorbent side (where an active acoustic side is present)
In Reflect-type models, the system functions primarily as a reflective noise barrier, with performance focused mainly on sound insulation, while absorption takes place on one side only – depending on the installation design.
The fence is suitable for outdoor use and is designed to withstand wind loads, temperature changes and varying environmental conditions, while maintaining mechanical stability and acoustic performance over time.
It is intended for infrastructure projects such as roads, railway lines, industrial zones, technical facilities and plant rooms, as well as private applications where an effective acoustic buffer against external noise sources is required.
Applications
- Roads and traffic routes
- Railways and transport infrastructure
- Industrial zones and factories
- Plant rooms and technical facilities
- Commercial complexes
- Perimeter acoustic fencing
- Private use in areas close to noise sources
