Rooftop cooling towers, exhaust fans and AHUs are common noise sources. ASPER composite acoustic enclosures use sound panel + 100mm glass wool + perforated plate + steel/aluminium frame, achieving Rw≥25dB, A-class non-combustible, perforation>20% and outdoor fluorocarbon coating, with acoustic access doors and framing. Delivered CNPC R&D Phase II and Shenzhen Finance Center rooftop enclosure detailing.
| Sound reduction Rw | ≥25dB (composite absorptive-absorptive) |
|---|---|
| Fire rating | A-class non-combustible |
| Absorption | 100mm glass wool |
| Perforated plate | 0.8mm perforated galvanised steel/aluminium, >20% |
| Facing | 1.0mm steel/aluminium |
| Outdoor finish | fluorocarbon coating |
| Options | acoustic door + framing |
panel+wool+perforated plate+frame coupled for sound blocking and absorption
all materials meet fire rating for rooftop sensitive areas
lets sound enter the absorbent layer while keeping strength
UV and salt-spray resistant for permanent outdoor service
Check four points: weighted sound reduction Rw (≥25dB for adjacent sensitive rooms), A-class non-combustible materials, perforated panel ratio and glass wool thickness, and outdoor fluorocarbon coating. ASPER meets all three hard metrics with test reports and detailed drawings.
Rw is the weighted sound reduction index; higher is better. For rooftop equipment (cooling towers/exhaust fans/AHU) near sensitive spaces, composite enclosures commonly target ≥25dB.
Rooftop equipment areas demand high fire ratings; both the facing and acoustic fill must be A-class non-combustible to limit fire spread.
The perforated panel is both a protective skin and an acoustic element; >20% lets sound enter the glass wool while keeping structural strength.
Yes. The enclosure exterior can be fluorocarbon coated for UV and salt-spray resistance in permanent rooftop service.
Yes. ASPER has delivered rooftop equipment acoustic enclosure detailed design, including composite panels, acoustic access doors and framing installation.
