Approved products, performance data, and substitution guidelines
CUSTOMIZABLE -- Supplier/brand for items marked [DEC] Decorative (fabric wraps, paint, trim, visible hardware), fastener brands (if matching pull-out and shear ratings), sealant brand (if matching acoustic and fire rating), surface finishes and colour choices on non-acoustic elements.
DO NOT ALTER -- Any product marked [AC] Acoustic Critical: insulation density and NRC, gypsum board density and thickness, damping compound type and coverage rate, resilient channel/clip model and spacing, door seal compression ratings, duct liner specifications, vibration isolator deflection ratings. Substitutions on [AC] items require written approval from the acoustic consultant with equivalent test data.
All insulation products are mineral wool (stone wool) based. Fiberglass batts are not permitted for acoustic applications in this project.

Mass is the primary factor in STC performance. All acoustic walls use the higher-density Soundshield Plus. Standard board is only permitted on non-critical faces.
Soundshield Plus provides -- more mass per square metre than Standard board. For double-layer walls this difference is doubled. Every 1 dB of STC improvement translates to a perceptible reduction in transmitted noise.
Apply 2 tubes per 4x8 sheet (or 0.5L/m²) between gypsum layers. Coverage: random bead pattern, leaving 50mm margin from edges. Green Glue requires 30 days to reach full damping performance. Screw second layer within 15 minutes of Green Glue application.
Even a 1% gap in a sealed partition can reduce STC by 10 dB. Every joint, penetration, and perimeter must be sealed with the correct product.

The float floor is the first line of structural isolation. It decouples the room structure from the building slab to prevent impact noise and low-frequency vibration transfer.
Float Floor Assembly
All rooms use a fully floating floor. The floor deck sits on Sylomer isolation pads at 400mm centres. Two layers of 18mm plywood are glued and screwed with staggered joints. A 10mm perimeter gap is maintained on all sides and sealed with Tremco Acoustical Sealant. No rigid connections to the slab or walls are permitted.
Ceiling tiles are selected per room based on NRC requirements. Higher-performance tiles go in rooms with stricter NC targets.
| Room | NC Target | Assigned Tile | NRC | Coverage |
|---|---|---|---|---|
| VO Live | NC-20 | -- | -- | 100% |
| Control Room | NC-25 | -- | -- | 60% (acoustic cloud) |
| Studio | NC-25 | -- | -- | 80% |
| Editing Area | NC-35 | -- | -- | 100% |
All ceiling tiles are mounted on standard exposed T-grid suspension (15mm or 24mm depending on product). Grid is wire-hung from the slab above, with a minimum 60mm clearance for the HVAC plenum. Plenum barriers must be installed above buffer spine and partition walls.
Layer-by-layer material list for each wall type. Expand any wall to see its complete BOM. All product names reference the approved materials above.
No material substitutions are permitted without prior written approval. Use this traffic-light system to assess proposed changes.
The following materials are explicitly prohibited in all acoustic assemblies in this project. Use of any prohibited material is grounds for rejection of the assembly.
