Just wanted to pass a long that for the price this form of low end absorption is by far the best bang for the buck I've dealt with. When I first built my traps down in FL, I had to order in the 2" Roxul boards that I layered on top of 703 FRK to trap 400hz> and left the foil on to put some mid range energy back into the room. Down in FL they don't sell Roxul in home depot's and you can't find it in bats like you can up here in Nashville.
The one I am talking about is a semi rigid, actually is pretty firm and dense, the price is where I was floored... 12 bats of this for around $45? I was able to cut triangles and stack them in one of my corners I could hear a lot of lowend build up, now there's no low end around it at all. I built myself an overhead cloud from 3 panel traps I had from my old room in FL, just a single piece of 703 on those, but I filled the space of the 2x4 up with this Roxul and you can really tell is just sucking up all that phasey lowend I was noticing when I had the Dirac off. There was a massive difference when I would flip it off before I did the cloud and that troublesome corner, but now there's a lot less.
Just wanted to pass this a long for anyone thinking about making some more traps or starting a new room project. For the money, this is some really great stuff.

Yeah, I've been suggesting rockwool for all absorption duties for a long time. Roxul is being sold in Georgia(USA) by Lowes too.
I made my flat panels from it, then used all the scraps to fill some of my bass traps.

I made all my panels with Roxul. Its inexpensive and works great.

Same on the roxul/rockwool (I think I might have gotten a different brand, but same stuff).
When I first looked in to DIY'ing some acoustic treatment, I bought some 703 from one of the online acoustic treatment stores. I don't remember what I paid, but it was clear that this route would be far too expensive to treat the entire studio. The big box home improvement stores in my area only carry consumer insulation, none of the industrial rigid fiberglass/rockwool stuff. I then found a rather large industrial insulation distributor about 2 miles from my house and gave them a call. Turns out theres no minimum order, I can pay with credit card and pick up in person. My jaw hit the floor when they started quoting me prices. For about the same price as the 8 slabs of 703 I had originally bought online I was able to pick up enough equivalent rockwool to require 2 trips in my rather large SUV to get it all home.
Moral of the story: if you're looking to DIY some acoustic treatment, look for an industrial insulation distributor in your area, give them a call, and see if they will sell to you. The pricing will most likely beat the pants off of any retail options you might have. They will also have a lot more available than just 2x4 2" sheets. I picked up some rockwool pipe insulation as well (I think it was like 2" think, 16" diameter, 4' tall) and made some TubeTrap-style round absorbers/diffusors. The selection a distributor will have can really allow you to get creative.

A great tip with the Roxul bats is to get one of those cheesy electric knives from the 80s. The kind with like two serrated knives that go back and forth against each other. Cuts the Roxul so so easily. Keeps your hands out of it too.

I wish I would've gotten the electric knife.
One other thing to mention: wear gloves and long sleeves when working with this stuff, and a dust mask isn't a bad idea.

I'm a contractor for a living, i've done 100's of insulating jobs, forget the electric knife, this is the ONLY way to cut any sizable job www.soundaway.com/insulknife_p/21002.htm , it works so well it's ridiculous, trust me on this, any other cutting device is a waste of time and money. This will cut through any insulation from fiberglass, ultratouch(the hardest to deal with) and rockwool, panels or batts. It is USELESS without the sharpener, i will swipe sharpen the blade after every couple cuts, it takes seconds and keeps you flying. |

LOL I use a bread knife I got at a thrift store. I've used my machete as well!

Gonna be bumping down to the basement of my current flip and finishing it out in a couple weeks. May have to give this thing a try. |

Home Depot across from the mall. Just make sure to get the Safe n Sound ones.... the low-end coefficient is near the same as the board. Cutting them into triangles and stacking them in the corner is probably the most effective bass trap I've ever made.... I mean on all of my panel traps, when I'd strap them across a corner you could still hear bass loading up when you got near the corner, with this, the bass in the corner or within a foot of it is totally GONE.
So, for around $150 you can do 4 corners if your ceilings are no higher than 8'

generally speaking for bass traps the best insulation solution is the less dense stuff completely filling the corner.
the more rigid board type stuff works better mounted off side walls or in shallower traps.
you could hedge your bets and fill behind a corner mounted rigid insulation bass trap with less dense stuff.

There looks to be different types, does someone have a link, so I know what kind to get?

I have Ready Acoustics 2x4 bags. They recommend 2x4 owens corning 703 rigid panels, can I use the roxul in the velvet bags without it getting into the air? It looks like loose insulation, are you building a wood frame and just stretching material around it? I guess I need to research building my own panels.

It's not loose.... it's semi rigid. You would need to build a frame that's 4" thick, kind of like the studs in the walls of your house. You could use a piece of mass loaded vinyl to cover the Roxul and then put a slotted or hole drilled piece of thin ply on both sides.

It looks like loose insulation, are you building a wood frame and just stretching material around it? I guess I need to research building my own panels. Here's a pic of mine:  I built 6 of these using 4'x2' 6" thick Roxul. I used 2"x6"s for the frame but would do it again with 1"x6"s instead. In your case I'd try 1"x4"s for your frame. I then cut some trim pieces and nailed them to the inside of the frame. I bought the fabric from a local sewing/crafts store in white and black rolls. I stapled the fabric to the inside of the 2"x6"s stretched tightly. Then I fit the Roxul inside the frame and just used strapping to hold it in place on the back of the panel. The trim looks nice but it's really only there to hold the insulation in the front. I'm moving this week and will be rebuilding these to go floor to ceiling in all corners of the room. Finally get to make a cloud over mix position. Excited about this as well. BTW- my bass traps are free standing and make great gobos in a small, shitty room.  |

This is a mock-up of some I planned on building when I actually have a room to put them in. It will hang on the wall using a French-cleat. I used some scrap 1x poplar. The face is actual grille-cloth and attaches just like a speaker grille. |

Nice, I need to do something like this also. My room is challenging, because of a radiator and one short wall that has a built in bookshelf with glass doors. The cloud is a tough one because I don't want to damage my ceilings and have to repaint them. I am thinking about going today and getting materials. I can just build frames for my Ready Bags. They come with mounts and straps for hanging on the walls. |

I feel as if this roxul isn't safe in my readybags, does anyone know more about this? I just don't want this stuff getting in the air.

I cut it with an Angle grinder.... Worst weekend in memory... 8) Man did that suck. Worked out great and the whole 22 panels cost me about 1/15th of what the commercial solution would have been  |

I contacted Ready Acoustics about my ready bags and installing roxul safe n sound bats into them. The only answer I got was we recommend oc703. I still do not know if the bags will contain the roxul and if it's safe. Does anyone know if I can safely install roxul in my readybags?

I would be more concerned about it getting beaten up without edge protection. I have roxul rapped in burlap and it's fine, but it's rock board 40. You could rap it in batting. |
