Equipment noise barrier, 2.5m high. Sound-absorbing steel panel with mineral wool core. NRC 0.85. For HVAC, generators, pumps, compressors. MOQ 50 m2, 10-20 day delivery.
Equipment noise barriers are modular acoustic enclosures designed to reduce industrial equipment noise transmission to surrounding areas. The 2.5m height is specifically engineered for typical industrial equipment β providing sufficient barrier height to block direct sound paths from generators, compressors, pumps, and HVAC units.
## Acoustic Design
The barrier panel is a composite sound-absorbing structure: - **Outer Skin**: 0.8mm perforated galvanized steel (sound-transparent facing) - **Core**: 50mm mineral wool insulation (80 kg/m3 density) - **Inner Skin**: 0.6mm solid galvanized steel (sound-reflective backing) - **Frame**: 1.5mm galvanized steel edge channel - **Acoustic Performance**: NRC 0.85 (absorbs 85% of incident sound), STC 32 (reduces 32dB through panel)
## How It Works
1. **Sound Wave Approaches**: Equipment noise radiates outward as spherical waves 2. **Perforated Face**: Outer perforated skin allows sound waves to enter the panel 3. **Mineral Wool Absorption**: Sound energy converted to heat by friction in mineral wool fibers 4. **Solid Backing**: Inner solid skin prevents residual sound transmission through panel 5. **Barrier Shadow**: Panel creates acoustic shadow zone behind barrier β typically 10-15dB reduction at receiver position
## Key Advantages
- **High Absorption**: NRC 0.85 β absorbs 85% of sound hitting panel surface. Prevents reverberant buildup. - **Weatherproof**: Galvanized steel + moisture-resistant mineral wool. Suitable for outdoor equipment. - **Modular**: Standard panel 2.0m x 0.5m. Connect to form any length and height. - **Self-Supporting**: Panels slide into steel posts β no additional framing needed. - **Fire Resistant**: Mineral wool core is non-combustible (A1 fire rating). Meets building codes. - **Maintenance Free**: Galvanized steel surface. No painting required for 15+ years.
