Building iso room addition, please help (pics)

[ghostFL]

Hello and thank you for having me here

My name is Brendan, a friend and I are constructing this iso room into his upstairs. His room to the left will be the studio. We already see the large AC unit as a problem, but when turned off, it isn't even there. We would like to build this frame, but now we are not sure of the best way to insulate the walls or finish them. Also, I was planning on getting just 2.5" poly foam, but if there is a better recommended material for the inner surface, I'm completely open top advice. Also, any advice on ventilation would greatly be appreciated as well. Thank you very muchhhhhhh

Nothing? =\

Probably not what you want to hear, but I wouldnt bother with a booth. I'd take the frame out, and put up rigid fiberglass panel on the walls. You can still use the area to record vocals, but making a little room to do it in wont accomplish much, and may sound worse imo.

In my "studio" I have two huge 7' tall 4' wide rolling partitions stuffed with rigid fiberglass (6 inches thick). I put them together at a right angle to make a little 2 sided corner "booth". Its open to the rest of the room. We just monitor with headphones and turn the monitors down to keep the bleed down.

You'd probably get more response in the studio design forum.

I've spent 15 minutes searching the site, where is this studio design subforum? :X

"Studio Building and Display" about 2/3 of the way down on the main forum page (under the "Special Forums" heading). You could *try* to get a mod to move this, but good luck finding one.

Oh yeah, I saw this thread a few threads below yours. Similar situation.

I'll move this thread over to the Studio Building forum later today... give you time to see this post. You can always track the threads that you particpated in by clicking on UserCP. This one will be listed there in its new location.

A list of mods are at the bottom of the main page. You can always PM me if you need some help.

I agree with the thoughts of not using a vocal booth if you can get away with it. A bigger room will sound better. If room noise is an issue, try to eliminate that first.

Sometimes, you just don't have a choice and need a booth. Then you would need to make it as dead as possible. Mass is what tames sound waves. If you want complete isolation, try doubling up the drywall. Be sure you know how much weight you're adding to the structure. I'm guessing for a vocal booth you won't exceed the structural limits. But I am just guessing, you need to know for sure... it is upstairs, right?

You can use owens corning 703 for treating the booth, lots of it ecverywhere inside. This is talked about at great length in the Studio Build forum. There's also a list of suppliers.

Hey, a Mod! lol

btw, I DEFINITELY would cover the walls with rigid foam board (i.e Styrofoam, polyiso, or any variation). Rigid fiberglass (703) or rockwool would be your best bet.

Unless you need to keep sound down to or from the rest of the house, you dont NEED a booth.

Yup, here I am.... And for future reference, if you think a thread is in the wrong place, you can always report it and make a comment to move it to the right place. The mods get email notices and can take care of it right away. Stuff like that helps a lot.

I've read up several ideas involving the drywall. Is it true I can just "double" up on the drywall with a THICK layer of caulk in between. And just fill in between the studs with DB batt insulation?

The problem with the house we are recording in, is it has a VERY open design. From the moment you enter the front door, all of the house is essentially connected by one large air pocket, not many hallways or turns... And there is a large outside double door patio deck 10 feet from our planned studio room. It is also in suburbia where there are quite a lot of lawns being cut, sprinklers, planes flying over in Orlando, etc. We plan on recording mostly hip hop, we should be ok with a booth that has its inside treated with some actual 2" thick studio foam. Also, I planned on getting my foam from this site, would you have any recommendations as far as thickness and style go?

For home resale value, we think we are going to go buy a door & frame for 200$ and add it into the frame. Would we be able to soundproof the door well?



Our plan thus far has been, Double drywalling each side, insulation inbetween the studs. DOUBLE insulation if possible? Can foam seal any cracks and openings besides the wire area, and then completely line the inside with foam from that site. We are wondering if building an arch in the top of the room or bottom would help with the dimensions???? And then finally, buying 8 of these hanging sound dampeners (if you agree with their use), and puting one on the inside of the booth door, one on the outside, 4 over the double patio doors, and 2 at the top of the stairs isolating that corner a bit more for kicks

After I get the initial build setup from your guys' help, I'd really appreciate any ventilation plans. As I have never had to build a makeshift vent, and especially not a quiet one into a soundproof room.


Thank you all so much for my warm welcome and your hasty response to my inquiry. I plan on making me trip to Home Depot tomorrow to get another notch done before working for the week and continuing next weekend.

That is what you need to define before anyone can offer any viable solutions. Also, you need to tell us EXACTLY what the existing conditions/construction is, you budget and a few other things..like what are you doing in this "isolated" space...ie...is this a vocal booth, or drum booth or rehearsal space...or what. AND what the predicted SPL of the sound will be...ie BASS DRUM...MARSHALL AMP @ 10....soft acoustical guitar...exactly what?

Your welcome, and welcome to the board. Although, I don't remember inviting you?( just kidding!)

I listed some of the noises in the post above. It is going to be used for mainly hip hop, but we will have vocalists in there singing too. Our budget is about 500$ Maybe more if its absolutely necessary

[Myriad_Rocker]

If your budget is that small, go with the large gobos like has already been stated. Make two of them and then put them together in a V shape. Stick the mic in the V and rap/sing/whatever.

Closed-cell acoustic foam is a waste of time - and styrofoam et al is completely worthless acoustically. You're looking for rigid fiberglass or rock/mineral wool @ 3-5 pcf.

Holy shit- huge typo- I definitely would NOT cover the walls with any type of foam- closed cell "styrofoam" or any of the "acoustical" foam.
Sorry bout that!

Correct- rigid fiberglass or rockwool all the way!

Building an iso room addition, please help (pics)

Are you...or are you NOT building a COMPLETE room that is an ADDITION to the house? Your pictures show a room that is ALREADY built, and even shows the existing drywall with some new framing etc, and you asked about adding another layer, amongst other things. PLEEEEEEEASE tell us the deal here.

If all you are doing is PARTITIONING OFF space in an existing room...I GOT NEWS FOR YOU!!

Unless you have a BUILDING PERMIT...you're making a BIG mistake. Partitioning off existing space in a home WITH"OUT a permit, is not only jeprodising your insurance, but peoples lives as well. Don't beleive me? Go talk to the building inspection department...maybe you'll believe THEM! This may seem like nonsense to you right now...but I'll guarantee you...it doesn't to the BID...and your INSURANCE company.
