Green Glue Noiseproofing Clip
The Green Glue Noiseproofing Clip delivers dependable acoustic isolation through its engineered rubber mount and stable load-bearing design. Compatible with standard 25-gauge hat channel, it reduces vibration transfer, improves STC performance, and provides a reliable, installer-friendly solution for high-performance soundproof wall and ceiling assemblies.
- Effective Board Isolation: Rubber-mount decoupling breaks the direct path between drywall and framing to hold real-world STC gains under Type X drywall stacks.
- Strong Testing Backing: Green Glue publishes third-party STC/IIC data across the assemblies its clip is specified in — the numbers behind our Better/Best walls come from those tests.
- Stable, Low-Deflection Design: The load-bearing steel frame limits sag under double-drywall + Green Glue stacks so the isolator keeps working long after install.
- Installer-Friendly Layout: Standard fastener pattern and 24" o.c. spacing match the rest of the clips we sell — no proprietary hardware, no bespoke channel spacing.

Noiseproofing Clip Project Calculator
Enter your surface square footage. We'll return a clip, channel, and screw count for your project — calculations run on our servers so estimates stay accurate as our field data improves.
Adds MLV over Good for a denser limp-mass layer.
Estimates follow the Green Glue standard clip and hat-channel layout (clips ≤ 24" o.c., hat channel 24" o.c.). A 10% coverage buffer is recommended to cover cuts and re-work.
STC Gauge
Compare how the Noiseproofing Clip performs across assembly tiers. Select an assembly below to see the resulting STC score.
Framed wall, single 5/8" Type X drywall each side, no 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.
