Hat channel
« on: February 05, 2017, 06:00:26 AM »
Okay from what i've read Hat Channel is the way to go over RC-2. My question is do I need to use a clip system or can I just screw them directly into the basement ceiling joists? I do not have the ceiling height by code to use the fancy clips with rubber, if clips are required it would be the basic low profile option.

Thanks

Using clip and channel is the best way to go, if you do not have the space for them use RC-2 resilient channel with 2 legs and our isolation tape to get the most benefit.

Do not forget to leave the 1/4" gap around the perimeter and fill with acoustic caulk.
Also, for first layer of drywall make sure you are using 1" drywall screws..anything longer will short out the channel.

Thanks Randy. One more question, does the second layer of 5/8" drywall fasten into the 1st layer of drywall or straight through to the joists?

All layers must go into channel, make sure your screw size for the second layer is not to long as to make contact to any joist.
