Fibreglass Ceiling Tile Acoustic Properties \u2014 Absorption Coefficients (125Hz\u20134kHz)
High-performance fibreglass ceiling tiles with painted fleece or neoprene face finish. Slightly higher absorption than mineral wool equivalents, especially at low frequencies. Available in standard grid sizes with Class A fire rating.
Absorption Coefficients by Octave Band
| Frequency (Hz) | 125 | 250 | 500 | 1000 | 2000 | 4000 |
|---|---|---|---|---|---|---|
| α (absorption) | 0.30 | 0.70 | 0.95 | 0.95 | 0.90 | 0.85 |
RT60 Impact
Installing 24m² of fibreglass ceiling tiles in a 100m³ room reduces RT60 by approximately 0.50s at 500Hz
