Complete assembly specifications for the float floor and decoupled ceiling systems across all five zones of the MediaVerse Studio Complex.
CUSTOMIZABLE -- Finished floor surface material (carpet, vinyl, engineered timber -- provided it sits on the specified underlay), ceiling tile or panel finish colour, suspension wire brand, access hatch frame finish, perimeter shadow-gap trim profile.
DO NOT ALTER -- Floating floor isolation pad type and spacing, plywood sub-floor thickness and layering, perimeter isolation strip material and width, ceiling plenum depth, ceiling hanger type and spacing, mass-loaded vinyl barrier location and overlap, insulation type and thickness above ceiling, air-tight membrane continuity. The floor and ceiling assemblies form the top and bottom of the acoustic isolation envelope.
The floating floor decouples the finished surface from the structural slab, preventing structure-borne sound transmission. Every room within the Yellow Zone sits on this isolated platform.
| Layer | Material | Thickness | Purpose | Notes |
|---|---|---|---|---|
| 01 | Structural concrete slab | 150 mm | Primary structure | Existing slab, verified level |
| 02 | Neoprene isolation pads | 25 mm | Vibration isolation | 400mm grid, 40 Shore A |
| 03 | Plywood subfloor (T&G) | 18 mm | Structural deck | Tongue-and-groove joints, glued |
| 04 | Resilient acoustic underlay | 5 mm | Impact noise reduction | Closed-cell rubber mat |
| 05 | Finish floor (varies) | ~8-12 mm | Wear surface | Carpet or vinyl plank by room |
| -- | Perimeter isolation strip | 10 mm gap | Edge decoupling | Acoustic sealant infill, full perimeter |
Floor deduction: -- cm (from SSOT-GEOMETRY). Total float floor assembly thickness (slab excluded) = neoprene pads (25mm) + plywood (18mm) + underlay (5mm) + finish (~10mm) = ~58mm. The remaining deduction budget accounts for slab surface leveling compound.
The ceiling is mechanically decoupled from the structure above using spring hangers, creating an independent mass-spring-mass system. Combined with the float floor, this achieves full "box-in-box" isolation.
| Layer | Material | Thickness | Spacing | Purpose |
|---|---|---|---|---|
| 01 | Structural slab above | Existing | -- | Primary structure |
| 02 | Spring hangers (Mason Type W) | ~50 mm travel | 600 mm grid | Mechanical decoupling |
| 03 | Hat channel / furring channel | 25 mm | 400 mm o.c. | Gypsum support framework |
| 04 | Rockwool Safe'n'Sound batts | 100 mm | Between channels | Sound absorption in cavity |
| 05 | RSIC-1 clips + resilient channel | ~15 mm | 600 mm o.c. | Secondary decoupling layer |
| 06 | Gypsum board (layer 1) | 12.5 mm | Full sheet | Mass layer 1 |
| 07 | Green Glue Compound | ~1 mm | 2 tubes / sheet | Viscoelastic damping |
| 08 | Gypsum board (layer 2) | 12.5 mm | Full sheet, stagger joints | Mass layer 2 |
| 09 | Acoustic sealant at perimeter | Bead | Full perimeter | Air-seal all edges |
Ceiling deduction: -- cm (from SSOT-GEOMETRY). Total ceiling assembly depth = spring hanger drop (~50mm) + hat channel (25mm) + rockwool (100mm) + RSIC + gypsum (26mm) = ~200mm. Finished ceiling height from float floor = -- cm.
Each room has been assigned specific floor and ceiling finishes based on its acoustic targets, equipment requirements, and intended use.
| Room | NC Target | Floor Finish | Ceiling Finish | Bass Traps |

The combined float floor and decoupled ceiling system achieves high isolation ratings for both airborne and impact sound transmission.
Structure-borne sound travels through rigid connections. The float floor + decoupled ceiling eliminates the direct structural path between adjacent spaces.
Perimeter Gap: The float floor must NOT touch any wall, column, or partition at any point. Maintain a minimum 10mm isolation gap around the entire perimeter, filled with non-hardening acoustic sealant. Any rigid contact will create a flanking path and compromise the entire isolation system.
Spring Hanger Loading: Spring hangers must be selected and loaded to match the actual dead weight of the ceiling assembly. Under-loaded springs will not deflect properly and will transmit vibration. Over-loaded springs may bottom out. Calculate: 2 layers gypsum + Green Glue + rockwool + channels = approximately 35-40 kg/m². Verify with the manufacturer's load tables.
Green Glue Cure Time: Green Glue Noiseproofing Compound between gypsum layers requires approximately 30 days to reach full damping performance. Initial performance is achieved within 7 days (~70%). Do not schedule critical acoustic testing until at least 30 days after final gypsum installation.
Ceiling height -- cm is the SSOT value — do not alter. This effective height is derived from: slab-to-slab (-- cm) minus floor deduction (-- cm) minus ceiling deduction (-- cm). Any modification requires formal change-order approval and re-computation of all RT60 values, modal frequencies, and HVAC clearances.

Strict sequencing is critical. The floor must be completed before internal partitions, and the ceiling assembly must be installed from the structure down.
