1. Which side of the channel is best positioned next to the wall? Does
the flange where the channel is attached to the joist go next to the
wall or or does the raised portion where the drywall is attached go
next to the wall? Or does it even make a difference?
2. Does the resilient channel fit snug to the walls?
3. Is the spacing on the channel 16' centers (three section per each
four foot width)?
4. What is the screw spacing for attaching the channel?
5. What is the screw spacing for attaching the drywall?
I appreciate any advice you may be able to provide in this matter.
Thanks much for your prompt reply.
Installing resilient channel
is a very cheap and easy method of achieving a good flat surface that
makes a better job all around. It might add 5 cents a square foot to
the job but will save time on call-backs and installation time.
I really enjoy your website and I'm sure I'll be referring to it as I
progress in the many work projects that are awaiting me in my
I am in the process of finishing my basement. I am installing R14 Roxul
between the 16" centered joist to add a little sound reduction effect.
Next I'll apply resilient channel (RC), and finally 1/2' sheetrock
attached with 1 1/4' drywall screws.
The questions I have are:
Thanks for the kind words about my site. Glad you're making use of it.
It doesn't matter which side of the channel faces the wall, I keep it
away to make it easy to screw.
Keep the butt ends of the channel about 1/4" away from the wall so it
catch and will be able to float.
16" centers is great and one screw per joist is good.
Drywall to channel, I screw about every 12".
