25-Gauge Furring Channel
The 25-Gauge Furring Channel delivers a rigid, 12-foot long, uniform steel mounting surface for wall and ceiling finishes. When paired with sound isolation clips, it separates drywall from adjoining spaces to limit vibration transfer, enhance acoustic performance, and support high-quality soundproofing assemblies in non-structural construction applications.
- Purpose-Built for Decoupling Assemblies: Designed to integrate with sound isolation clips, allowing drywall to be mechanically separated from framing to reduce vibration and improve overall assembly performance.
- Straightening & Plane Control: Creates a true, level mounting surface over uneven substrates such as concrete, masonry, or steel — essential for a clean, aligned finish and reliable installation results.
- Optimized 25-Gauge Strength: 12 ft long and manufactured from cold-formed steel with a hemmed edge — thin enough to fly for finish support without unnecessary weight or over-engineering.
- Versatile Wall & Ceiling Applications: Suitable for direct-attach, suspended, or clip-mounted systems in residential, commercial, and multi-family construction — a major upgrade over resilient channel reliability.

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 manufacturer's standard clip and hat-channel layout. Select the clip you plan to pair with the channel to size the pair for your project. A 10% coverage buffer is recommended to cover cuts and re-work.
STC Gauge
Compare how the 25-Gauge Furring Channel 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, Rockwool 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.
How 25-Gauge Furring Channel compares
| Model | Best For | Acoustic Intent | Strength / Handling | Notes |
|---|---|---|---|---|
| 25ga 7/8" Furring Channelthis | Most clip-over-channel walls / ceilings | Supports decoupling when used with isolation clips | Lightweight, fast install | Most common — hat for standard clip systems |
| Heavier Gauge Hat Channel | Heavier finishes / wide spacing designs | Same concept, stiffer with more mass | More rigid, heavier handling | Often specified by engineer for load / deflection targets |
| Resilient Channel (RC) | Budget wall upgrades (limited detail) | Flex hinge relies on non-installed easily | Not a rail for clips | Different product class; avoid when decoupling is critical |
