For architects & specifiers
Every acoustic value below is measured per ISO 11654:1997 by an accredited laboratory (University of Liège or Peutz bv); the test reports are public and linked underneath. Greenmood surfaces are made from 100% natural materials — preserved plants and cork — with no plastic acoustic core.
| Material | 100% natural cork: 92% cork granules (ground, purified and dried cork oak bark), 8% BioCol Bs 30 binder |
|---|---|
| Sound absorption | NRC 0.2 to 0.4 depending on tile model (ISO 11654:1997, Peutz bv, Netherlands) |
