I am in the framing stages of building my shop. My dust collector will reside in the garage connected to the shop. I am thinking about running my main DC line into the shop through the rim joist and through the TJI's. I have one alignment I can use and meet the manufacturer's distance requirements. I think I can make it work for my setup.
My ceilings will be 9', and the TJI's are 11-7/8" tall; it seems a waste not to use that space to hide some of the DC piping. The hole size would be be 6-1/2" or slightly less. There will be an office above the shop (occupied by me, so noise wouldn't necessarily be an issue). While I am not that concerned about the noise upstairs - we might turn the upstairs into an apartment at some point in the future. To that end, I am going to insulate and sheetrock the shop ceiling to separate the spaces as much as possible.
My Questions:
- Is it a bad idea to enclose my main line? I know this doesn't help but I haven't decided if I am going metal or plastic.
- I am wondering about effectively sealing the penetration where the line would exit the drywall.
- Do they make a large "donut" or something like a big grommet that would help with isolation and vibration through the joists?
Appreciate any advice
