My current basement is unfinished and would like to finish it. I’m framing an inch or two off the cinder block. I would like to use to Rockwool for better sound protection and just in case there is moisture. I have French drains with plastic dimples coming up 6“ from below the floor just in case there is any moisture from the wall. I would like to keep the Rockwool and inch off the cinder block so it doesn’t absorb moisture.
I was considering faced Fiberglass so I can staple it to the studs and keep it off the cinder block. Is there a trick to keep the rock wool from settling on the cinder block? I guess I can install thin strips of wood behind the 2x4 to hold it in place but thinking there must be a better way. Thanks so much.
