Resilmount A237R
Resilmount A237R Sound-Isolation Clips drastically reduce structure-borne noise, creating quieter spaces in a few simple steps. Easy to install these compact clips offer excellent acoustic performance for any sound-sensitive project, providing peace without compromising design or budget.

- Superior Noise Reduction: Structure-borne vibration and acoustic drywall isolation prevent sound transfer across framing for enhanced STC performance.
- Compact & Easy Installation: Fits 25-gauge hat/furring channel and snaps easily into place — streamlined for fast, painless installations.
- UL-Tested & Trusted: Third-party certified for use in fire-rated assemblies. Meets industry standards for safety and performance.
- Budget-Friendly Upgrade: Delivers significant sound isolation improvements at a small, cost-effective addition to any project.

Adds MLV over Good for a denser limp-mass layer.
Estimated STC — Planning use only
This value is an approximate assembly projection, not a project-specific assessment, certified laboratory test result or performance guarantee. Actual performance varies with the complete assembly, installation, flanking paths, penetrations and site conditions.
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 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.

Best — Clips + Double Drywall + Green Glue
R13 insulation · 7/8" hat channel · 5/8" Type X drywall · Green Glue · 5/8" Type X drywall.

Better — Clips + Single Drywall
R13 insulation · 7/8" hat channel · single 5/8" Type X drywall each side.
Good — Standard Assembly (no clips)
Baseline wall assembly, single 5/8" Type X drywall each side of R13 insulation.
