Build sequence

STRUCTURE ABOVEROOM BELOW1

1 Hang isolated hangers

Fix spring/neoprene isolated hangers to the structural soffit, keeping the 50mm plenum. Hangers decouple the ceiling from the structure.

STRUCTURE ABOVEROOM BELOW2

2 Hang the channel grid

Suspend the decoupled channel grid from the hangers — no rigid contact with the soffit or walls.

STRUCTURE ABOVEROOM BELOW3

3 Install the acoustic ceiling

Fit the acoustic ceiling (Rockfon Sonar E tiles / 2× gypsum where isolation needs it). Seal the perimeter; no air gaps.

4 Hang the ceiling clouds

In Control + Studio, suspend the RWA45 ceiling clouds at ~245cm AFF over the mix/mic position.

5 Fit the acoustic access panel

Install the STC-rated gasketed access panel for HVAC maintenance. Keep it OFF the VO Live mic position; gasket fully.

Golden rule: The ceiling must stay decoupled (isolated hangers). The access panel is the weak point — use an STC-rated gasketed hatch, never a plain drywall hatch.
