Joist HarmonyBLOKS Acoustic Felt Room Dividers use narrow angled openings and folded planes to create a clean directional pattern. Repeated across a screen, the linear geometry produces subtle movement and shadow for offices, reception areas, hospitality spaces, schools and residential interiors.

The dimensional PET felt helps absorb reflected sound and reduce echo and reverberation while defining open areas and adding partial visual privacy. Build Joist vertically or horizontally to create decorative privacy screens, acoustic partitions or larger floor-to-ceiling installations. Available in five wood- and terrazzo-inspired Overlay finishes.

  • Eight 11.625 x 11.625 x 4.875 in blocks per box
  • Includes outer wraps, stands and connectors
  • 100% PET felt containing a minimum of 65% recycled content
