Adds MLV over Good for a denser limp-mass layer.
Estimates follow the manufacturer's standard clip and hat-channel layout for walls and ceilings. A 10% coverage buffer is recommended to cover cuts and re-work.
STC Gauge
Compare how the A237R performs across assembly tiers. Select an assembly below to see the resulting STC score.
A237R clips + hat channel + double 5/8" Type X drywall with Green Glue between layers, R13 batt in joist bay.
- STC 30-39: Loud speech clearly audible next room.
- STC 40-49: Loud speech muffled — normal residential wall.
- STC 50-59: Loud speech barely audible; suitable for offices & multi-family.
- STC 60+: Approaches studio-grade isolation.
How A237R compares
| Model | Primary Use | Hat Channel | Typical Layout | Isolation Element |
|---|---|---|---|---|
| A237Rthis | Resilient sound clip for walls & ceilings | 7/8" or 1 1/2" | ≤24" o.c. hat · ≤48" o.c. clip spacing | Thermoplastic rubber sound cells |
| A237 | Direct furring bracket (rigid) | 7/8" or 1 1/2" | ≤24" o.c. hat · ≤48" o.c. clip spacing | None (rigid mount) |
Applicable Assemblies

Best — Clips + Double Drywall + Green Glue (Ceiling)
R13 batt in joist bay · 7/8" hat channel @ 24" o.c. on A237R clips @ 48" o.c. · 5/8" Type X drywall · Green Glue · 5/8" Type X drywall.
Better — Clips + Single Drywall (Ceiling)
R13 batt in joist bay · 7/8" hat channel @ 24" o.c. on A237R clips @ 48" o.c. · single 5/8" Type X drywall.
Good — Standard Ceiling (no clips)
Baseline joist ceiling with R13 batt insulation and a single 5/8" Type X drywall layer directly to joists.
