Acoustic clouds for suspended T-bar grid ceilings

Sizing, spacing and hanging height for clouds under suspended T-bar grid ceilings.

2 minute read · Updated Nov 2026

A cloud is a flat panel hung horizontally below the ceiling. Because both faces and all edges are exposed, it absorbs up to 1.5 times as much as the same panel flat on a surface.

  • Hang 6–12 in below the ceiling for a flat look, or lower in tall rooms to bring absorption closer to people.
  • Cover 20–40% of the ceiling area.
  • Group clouds over the zones where people talk: tables, desks, seating.
  • Leave space around sprinklers, lights and diffusers.
