I’ve got a 20’x12’ vaulted ceiling, 4/12 pitch that I want to install resilient channel on to reduce the risk of cracking; sound damping is not important. Trusses are just plain 2x6’s in the roof. Would I install the resilient channel perpendicular or parallel to the trusses, and subsequently what direction would I install my sheeting in relation to the RC? I haven’t been able to find any good info online or in manufacturers install specs in relation to vaulted ceilings. Thank you.

I found this

"Resilient channel should be installed on Cathedral Ceilings (single or double angled ceiling) with the center of the face of the channel 6 inches from the top to permit a floating angle wallboard installation. Resilient channel must be installed with mounting flange down."

at the following website.


And of coarse much info is available on YouTube such as this YouTube vid.

  • +1 for mentioning the boards are right angles to the channels too.
