Worth knowing:
- αw 1.00 is reached over a bonded 30 mm mineral-wool base, not in mass. Applied directly at 20 mm, it is αw 0.60.
- Green plasterboard is the recommended substrate.
- Repairs with a 38 kg mini machine.
- Vacuum with a soft brush head, or dry-ice clean.
- Features
- 0.70 NRC at 20mm in Mass
- Class D ISO 11654. AW 0.60
- 5- 20 mm in mass-applied build range
- 100% Recycled Cellulose Fibre
- When to Specify it
Specify it when you want a sprayed finish with almost no visible grain.
- Workplace ceilings where the finish should disappear
- Retail and showroom soffits
- Rooms where a Class A result is needed but the grain must stay fine
- Performance by Thickness
Absorption is a function of thickness.
Specify the thickness against the target, not the headline figure. Sound absorption coefficient by octave band, manufacturer-published.
