best insulation for walls in grow room

[adower]

Framing up a room here in the future. What is the best type of insulation to use between the drywall and osb?

Are you using fiberglass to fill the gap in between the studs? It sounds like you are using the flat insulation board right?
I just framed a room and used R-13 batt insulation between the studs, I couldnt be happier!

I cannot get the link to work. I tried like 6 times to change it...

Yea i do the same thing as mustang, works great

 

[old shol4evr]

might look into cardboard insulation, was watching a diy show and they claim that the cardboard insulation not only insulates it sound deadens ,sounds like a great thing especialy if you have the honor of a bad neighbor

I used a few rolls of R-13 fiberglass for the inside of my walls.

Nothing better than cheap fiberglass, per lab testing. It's also the cheapest insulation

 

[nevergoodenuf]

Lowe's sell a shredded denim insulation that works great. No mask and long sleeves. It's also so denser and costs about the same.

R-13

Celotex/kingspan/ecotherm rigid insulation boards. Scrap the osb use marine rated ply instead, osb don't like moisture

without a doubt the best insulation would be closed cell foam insulation, it comes in a liquid form in tanks and is sprayed into the wall cavity and expands, It is however expensive as hell,

Closed cell would of course be the best but expensive and not exactly DIY Friendly. Fiberglass batts suck. They will work but if you're willing to spend just a little more, what you want is Roxul Stonewool. Much Much better.

Home depot, Lowes, etc...they all carry it. Easier to install. Safer. Will not absorb moisture. Much better sound barrier. Just plain better.

Just plain better.

Not installation wise. I Fucking hate thermafiber!

Why? I found it incredibly easy.

Try slicing it up, and stuffing it in between slip track(top track)over-head. I'm a metalstudframer(drywall/lather)by trade. I fucking hate that fucking shit! Did I say I hate it yet? Lol

I agree closed cell is the best, but usually not practical.
If needing more sound proofing/sound deadening than what fiberglass batten insulation offers, personally, I would incorporate a sound deadening system to the framing. Chase wall, resilient channel, etc.

For thermal insulation, foam is best.

For acoustic isolation, the cheapest fiberglass is the best. Foam is the anti-christ for sound, however. Its density conducts sound from one side of a wall to the other.

Know that insulation doesn't do a hell of a lot for sound isolation. Much more impact by installing decoupled double studs and double 5/8" drywall.

Rocksilk flexible boards work good for sound.

 

[Rrog]

^^ They work great to reduce echo coming off the surface of a wall. ^^

They will not work great IN a wall or ceiling, however. Too dense.

EDIT: I'm referring to soundproofing only, here. Best insulation for sound isolation is cheap ass fiberglass.

See my post above.
Chase wall and resilient channel. It's usually how we do it
Reduce contact from one side of wall to the other.
Afterall, sound is transmitted through vibration.
