Sound Insulation?

[THC•20]

How many growers out there use insulation padding or w/e on your walls to stop sound from coming from out of the grow room. I was thinking about getting a new place with a room specifically for my green friends but trying to invest in some type of insulation for all the walls and floor of the room if possible. I'm just wondering if any one could help me or point me in a direction on this topic. I'm determined to make my next grow room so stealthy that not even I know that I grow there lol.

Just get some cheap R34 maybe? Or something with a lower thermal retention rating if its too expensive.

Go walk around HomeDepot for 30 minutes and I'm sure you can figure it out.

Home depot sells acoustic deadening panels in their ceiling tile department, you can get it in smaller squares but maybe they sell it in larger pieces as well? I am using it on my cab to insulate the equipment portion and it works very well.

I do not have sound insulation in my grow cuz it's in a place that sound is not much of an issue. But if it were I would hang homasote or sound board (cheaper) then a layer or two of thick drywall. The trick is to use as FEW screws as possible when hanging the soundboard to the studs. They transfer vibration which is bad in terms of sound transmission. Do not screw the drywall into the studs, screw it into the soundboard. This helps "detach" the drywall from the studs. Lastly (the hardest part) is that you do not want any of the walls, floor or ceiling touching. Leave a 1/8" - 1/4" at all points where they all meet, ie: floor to wall, wall to wall, wall to ceiling (as well as door and window frames). Then fill the gaps with sound caulk and mud as usual. The door (if there is one) should be solid core then caulked and sealed. You have to go to a drywall/building supply for the soundboard and caulk. HD or Lowes do not carry them. At last check Menards had homasote but not the cheaper soundboard or the caulk.
You can take it a lot further than this but I think a room as described above would be all but silent from outside.

Look in the insulation department at Home Depot. They have 4x8 sheets of 'sound board'. About $15 a sheet. I've used it a couple of times, it works good.

Roxul Safe N Sound - sound deadening and fireproof.

Also, resilient channel keeps drywall off the studs and prevents diaphragmatic action from transferring sound. Double alternate stud walls with a gap in between, double layers of drywall, rubber mount of fans all help soundproof a room. The limits are space and $$$.

Much info hear regarding soundproofing - http://www.gearslutz.com/board/studio-construction-acoustics/

No problem Pseudo.

This is good to know, HD didn't have it a couple years back when I installed it in my bedroom (I live in a loud area). $15 is about what I paid at a drywall supply but HD is much more convenient

With R-13 (flower box, 2x4 studs), R-19 (space in between flower box and basement room) and plywood/drywall on one side and just R-13 + plywood/drywall (room inside a room), I can't hear a damned thing behind that wall with two 8" Vortex's and a 12" Vortex running w/o ducting! It's virtually silent, even if I'm trying to listen for it. Only noise is the exhaust vent outside.

I guess once I plug in the 5 oscillating 16" fans it'll increase the noise a little bit, but then again ducting these inlines will reduce the noise a bit too. Even with increased noise I think it will still run silent.

I think a "cheap" solution like R-13 + R-19 (or just R-13 + R-13) using staggered studs should be plenty for most situations. A duct muffler will also help for the exhaust.

Home Depot has 40' x 15" rolls of vapor-faced R-13 for $10.

Mind if I throw my 2 cents in here? I've worked on soundproofing for many many years and here's the sum of my knowledge......

Sound "deadining" material such as foam, egg-crate, fiberglass, accoustic board, and similar items are all designed to eliminate echo and reverberation within a space. They are not appropriate for stopping the transference of sound thru a wall, ceiling, or door.

The only thing that will contain sound within a space and not allow it to pass through the walls is additional mass. At the high-end, you can purchase lead-lined sheetrock, but I doubt you want to deal with the cost and weight. This is what we use to contain conversations within conference rooms so they can't be heard in the halls. The poor mans alternative is simply to double up on the sheetrock using 2 layers of 5/8" Fire-Code. Its cheap, easy, and works great on the walls. If you plan on hanging it from the ceiling, make sure the substructure is strong enough to handle the load and use fasteners with washers.

As far as the floor goes, the ideal solution is a solid piece of EDPM rubber. EDPM is used to line small reservoirs, and fish ponds. Its easily purchased in any size sheet without seams. Its inert to any chemical or water spill, soft on the feet, just rolls right out, and is very dense offering alot of mass in a thin sheet.

All of this is JMHO, but they are solutions used every day in the real world.
