attaching cloth wrapped rockwool to ceiling/concrete walls?

[freakk guitarist]

i have some rockwool insulation, that im about to wrap in cloth, but i was thinkingabout how im supposedto attach it all to the walls?? i tried glueing one peice but since the fabric is not PERFECTLY tight, it saggs off the wall and looks unprofessional.

how would you guys advise me to get around my problem?

Ian - ask your rockwool people - there is a system of plastic pins like this:


you glue them onto the wall/ceiling then push the rockwool against it so the pins stick through. You then slide a plastic fitting down the pin and tighten. you then snip the unused bit of plastic pin off.

Otherwise I'd try glueing (contact adhesive - the type you wait for both sections to become tacky then join), a sheet of thin plywood to the rockwool and then glue that to the wall.

The cheap version I use is 3" finishing nails (you know, the ones with virtually no head on them). Nail a couple into the wall, push the fabric wrapped panel against them. then pull down the panel, poke holes where the nails made indentations, and shove them onto the nails.

For the ceiling, you can do something similar to the pin thing by getting some long nails with heads on them and some washers, put a washer on the nail, and hit the nail through the rockwool into the wall.

Instead of washers, I had a moroccan theme thing in the vocal booth, so I cut out paisley and swirly shapes out of 1/8" ply, and spraypainted them black.
