An innovative, eco-friendly acoustic insulation solution
NoiseSHIELD is a spray-applied cellulose system engineered to absorb sound energy, reduce echo and reverberation, and help control rain noise transferring through metal roof sheeting — for a wide range of noise-sensitive environments.
Designed around real-world noise problems
Absorbs unwanted sound
Engineered to absorb sound energy rather than simply block it — reducing echo and reverberation in open, populated spaces like call centres, cafés and auditoriums.
Controls tropical rain noise
Highly effective at reducing the thunderous rain noise that transfers through metal roof sheeting — a signature problem in Philippine buildings.
Applies to almost any surface
Spray-applied to roof sheeting, concrete slab soffits or drywall — including around fittings, ducts and irregular structure where rigid panels cannot go.
Eco-friendly by design
Made from locally collected recycled paper treated with borate minerals — a natural fire retardant, mold inhibitor and pest deterrent.
Healthier, safer spaces
Reducing excessive reverberation can improve acoustic comfort and speech clarity in busy spaces — while the material stays non-toxic for installers and occupants.
Aesthetic flexibility
The finish can be tailored — including white finishes for exposed architectural ceilings — so acoustic performance does not cost you the design intent.
Where NoiseSHIELD performs
Acoustic & thermal data
IFI cellulose, tested to ASTM C423 on solid backing. Performance varies with installed thickness; final specification is determined according to project requirements.
| Thickness | Imperial | 125 Hz | 250 Hz | 500 Hz | 1000 Hz | 2000 Hz | 4000 Hz | NRC | R-Value |
|---|---|---|---|---|---|---|---|---|---|
| 16 mm | 5⁄8″ | 0.05 | 0.16 | 0.44 | 0.79 | 0.90 | 0.91 | 0.55 | 2.2 |
| 25 mm | 1″ | 0.09 | 0.23 | 0.77 | 1.01 | 1.00 | 1.05 | 0.75 | 3.6 |
| 38 mm | 1½″ | 0.15 | 0.51 | 0.95 | 1.06 | 1.03 | 0.98 | 0.90 | 5.5 |
| 50 mm | 2″ | 0.26 | 0.68 | 1.05 | 1.10 | 1.02 | 0.98 | 0.95 | 7.2 |
| 64 mm | 2½″ | 0.41 | 0.84 | 1.05 | 1.07 | 1.03 | 0.99 | 1.00 | 9.2 |
