Use Of Furring Channel
>>These channels are a popular and efficient low-cost method of reducing sound transmission in steel or wooden framed partitions. The Channel decouples the drywall from the structure, preventing sound from traveling through.
>>Important Note: This product is NOT to be used with Sound Isolation Clips, which require Hat Channels for installation. We highly recommend the use of Sound Isolation Clips and Hat Channels for proper decoupling which will eliminate any short circuiting that Channels are prone too and will give a higher degree of decoupling.
Dimensions: 2.0" W x .5" D
Length: 8.6' (102")
Thickness: 25 Gauge (18 Mils)
Weight: .16 LB/Ft (1.28 LB/Channel)
Install Resilient Channels at right angles to the framing member. The slotted holes should be positioned directly over the framing member.
Use the screw holes to attach channel. If no hole is located at the framing member, attach through the mounting flange
No more than two layers of up to 5/8" drywall should be applied.
On wall framing members, channels should be installed with mounting flange on the bottom. The starter row (closest to the floor) may be installed with mounting flange upward to accommodate fastening to the frame.
Installing on walls: Channels should be spaced 24" OC maximum
Installing on ceillings with 24" OC Framing: Channels should be spaced 16" OC maximum
Installing on ceillings with 16" OC Framing: Channels should be spaced 24" OC maximum
Walls: Lowest row should be no more than 2" off the floor, Highest row should be no more than 6" from the ceiling.
Ceilings: First and last row should be no more than 6" OC from adjacent wall.
Use screws only, nails should not be used.
Splicing should be done by nesting the ends of the channel directly over the framing member and screwing through the mounting flange.
Additionally, channels can be butted over the framing member leaving a minimum 1/16" gap between channels.
Avoiding Errors with Channel Installation:
It is essential that channels be installed properly for them to work as intended.
Some main points to keep in mind:
Ensure the mounting flange is applied in the downward position. By keeping the flange down the weight of the drywall will pull the channel away from the stud, thus improving the sound rating.
Screwing on top of a stud can potentially 'short circuit' the channel. Also, ensure the fastener you are using is not long enough to penetrate the stud.
