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.
Clips + hat channel + double 5/8" Type X drywall with Green Glue between layers, R13 insulation.
- 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.
