Acospray DC2 1.0 - Acosorb Acoustics
The workhorse of the range and the widest build band — 5 mm where ceiling height is tight, 45 mm where the room is hard. Absorption peaks across speech frequencies at about 25 mm, which is why it suits open-plan offices.

- When to Specify it
Specify it when you have a reverberation target and need to tune the thickness to hit it.
- Open-plan offices and boardrooms
- Hotel lobbies, restaurants and bars
- Classrooms, libraries and halls
- Swimming halls and semi-outdoor soffits — it is hygroscopic
- Healthcare waiting and consulting rooms
- 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.
