metal furring channel for soundproof walls

Metal furring channels, commonly known as hat channels, are integral to constructing soundproof walls. When combined with resilient sound isolation clips, they decouple drywall from the framing, effectively reducing sound transmission.

 Installation Guidelines

For optimal soundproofing, adhere to these installation practices:

• Channel Orientation: Install metal furring channels horizontally, perpendicular to wall studs.

• Spacing:

  • Clips: Position resilient clips (e.g., Resilmount A237R) no more than 48 inches apart.

  • Channels: Space channels no more than 24 inches apart.

• Drywall Installation:

  • Leave a 1/8" to 1/4" gap around the perimeter of the drywall.

  • Fill this gap with acoustical caulk to prevent sound leakage.

• Fastening:

  • Use appropriate fasteners based on the substrate (e.g., wood, steel, or concrete).

  • Ensure that screws do not contact the underlying framing to avoid compromising the sound isolation.

 Product Recommendations

When selecting metal furring channels for soundproofing, consider the following options:

• Trademark Soundproofing Resilient Metal Hat Channel:

  • 25-gauge, 7/8" depth, 2.5" width.

  • Hemmed edges for added strength.

  • Compatible with standard resilient clips.

  • Available in 8.6' lengths. 

• Soundaway Drywall Furring Hat Channel:

  • 25-gauge steel, 7/8" height.

  • Sold in 6' lengths, packs of 20.

  • Ideal for pairing with Kinetics IsoMax or RSIC-1 clips. 

• ClarkDietrich Furring Channel:

  • Hat-shaped, corrosion-resistant framing component.

  • Suitable for furring out masonry walls and ceiling assemblies. 

For optimal performance, use 25-gauge channels, as they provide the necessary flexibility for sound isolation. Avoid 20-gauge channels, which are stiffer and less effective in this application.
