Thanks, Prunedale. As a musician/soundguy I know a bit about acoustics but was just wondering about that ductboard stuff and if anyone had tried it. I don't know if 3/4" of insulation would do it. The foam in the studio works great but is so expensive it ridiculous. I think if I move my cloning cabinet to another wall it would help some. I was just thiking of killing two birds with one stone; mylar and insulation in one package. I'm just cheap and wanted to use somebody's experience rather that spend the cash myself (might as well be honest).

Mylar on one side yellow fiberglass insulation on the other about 1" thick. My grow room is completely sealed up from the rest of my house secret door etc. I do get some smell I think from opening the door. But,y problem is noise, odd fan like noise coming from a wall in the bathroom, can't hear it over the bathroom fan but when it's not on there is noticeable noise from the room. I Rating: 5
