It's been a while since I have posted to this group, but I try to read everyday. I am in the process of finishing my new 24x30 shop and had a question about my DC piping. I built a 4x8 bump out on the back of the shop and will put the DC and air compressor in there to kill the noise. I was planning to run the piping from there , above the ceiling joists and down through the finshed ceiling. I will then blow 12-14" of cellulose insulation in the attic. My concern is that there will only be about 3-4" of insulation under the piping with the remainder around and over it. The question is whether the warm air flowing through the piping will cause it to sweat. I don't think it will but I value this groups opinions. I would hate to do it this way and find out later that it was a mistake.
Thanks in advance as I humbly await your responses.
