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.
