Is Roxul Rockboard 60 rigid enough to not require a frame (more rigid than 703)?

[danbronson]

https://www.readyacoustics.com/ sells DIY bags that basically come with four plastic corner pieces and a bag to slip 703 into. Looks like the 703 is pretty stiff, so it's not a big deal that there is no frame to support it. Is Roxul Rockboard 60 similar or will it sag?

[1ManBand]

i have those ready bags with rockboard 60 and so far its holding up real good. im thinking if it ever starts to sag i'll just superglue a thin peice of wood..3 inches by 4 feet o the sides. Right now it looks like i wont have to do that in a long time.

[1ManBand]

i wanted to add.. i mostly have 6 inch panels.. that might be a reason why its holding up so good.. but i have 3 2 inch panels that make a cloud and they are a little flimsy but the way i hung them wont let them lose shape and disform. I also have 6 4" inch panels for the first reflection points. im just trying to say.. the thicker the better it will hold up. And remember u can always make some ghetto support.

I recently made traps with Rockboard 60, using full wood frame. They are nice but heavy.

In my non-pro opinion,i would say that it is be possible to do a no-frame version with it, they are hard enough for that,but be sure to place them where nobody will touch them, as they are fragile, corner could easily detach, or hole can be punched through.

I am in the process of making costwise traps to add to my room, and will be making in the next days traps with no frame around, with an even more soft material,and at half the weight, the Roxul Safe and Sound stuff(similar in technical data to 703).

Since they will be placed high in the room, i am not concerned about protecting them from the 'other' people, anyway, a board of Safe and Sound cost around $5 a board(as of around $20 for the Rockboard 60), so if it don't work... it is not a great loss and i will have been having fun experimenting with it.

Awesome. Thanks for the response. I plan to go nuts on this stuff and do 20 6" panels around my room. I was hoping the 6" panels would be stronger, but I wasn't sure if the added weight would counter that. You've reassured me, and glueing a thin piece of wood along the sides is not a bad idea at all.

Now I just need to find somewhere that sells cheap Rockboard 60. Did you get yours from a local commercial/industrial insulation supplier? Or through a place like Acoustic Panels by ATS Acoustics? What was the cost per panel if you don't mind me asking? Thanks again.

EDIT: Thanks for both responses. I just now saw your reply, Halexx.

[Halexx]

By the way,

i wrapped them in weed stop to be sure that the fiber stay in the traps, and tighthening the weed stop around the board made them stronger, like sofa pillows.

For the supplier, you may not have that much choice:

ROXUL® The Better Insulation - Where to Buy

Note that Home Depot don't stock the Rockboard in Quebec, and not in their website too.

Have fun building traps!

Even more fun hearing the result!

My most pleasure is mixing in my new room, i hear more clearly every change i made to the music,fader seems more responsive, it's like putting light in a room for an art painter: before i heared blue, now i hear light blue, dark blue, navy blue, etc...

In Quebec Sonopan might be an option. You can get that at Reno Depot.

I made some traps with mineral wool and sonopan and it works fine. Left a couple of inches of air between the pan and wool.

Cheers

Am i wrong or Sonapan is for isolation, not absortion?

[Joel DuBay]

Several locations offer Oc equivalents.

Knauf Canada can be found at insulation supply stores. As well, you should be able to find CertainTeed (a Canadian brand) of Mineral fiber. Rockwool is a good absorption medium, but we generally stay away from it (if possible) because it tends to be a bit more crumbly (and heavy) without supports (frames). The other thing I am hearing from folks buying rock wool products, is that the material dries out, hence the potential crumbly nature of the product.

Roxul, rock wool, OC, CertainTeed, John Mansville, Knauf, all make good absorption mediums.

I just made two 4 inch traps with a wood frame seems to hold up nice. I covered both sides with fabric. But the front side has another layer of fabric, is it ok that the back only has one layer of fabric? I'm not mounting to the wall it will just sit in the corner. Thanks.

[Glenn Kuras]

That should be fine. BTW I have been working with mineral wool for years and it does not dry out or crumble. In fact it is dry when you get it.

One other way you can go is Sound Proofing, Soundproofing Material: Lowest Prices - Audimute Soundproofing for the covers which work great with mineral wool and will save a TON of money. The company had some slipcovers that they sold for around $15.00 each but they are not on the website anymore. I called them and talked to Lorna (I think one of the owners) and she said there are a few left. You might want to contact them to see if you can pick them up.

How thick/thin of a fabric is needed with the Roxul 60 to balance covering with color, with not ruining the effectiveness?

thanks,

It really is not about thick or thin but if it is open weaved. If you can blow through the fabric then it should be fine.

What fabric can I use thats strong, and breathable, but blocks the fibres from leeking into the air? I'm using rockboard 60 sheets. Also, what material is recommended for the high frequencies?

Guilford of Maine. Expensive stuff but looks great and is fire rated. More high end acoustic companies use it. People like US (sorry shameless plug) and RPG.

Thank you for your response. Where do I get this. I'm in Canada, and I don't think this product is ready available. What can I use that equal or semi equal to this product that I can buy at a local hardware store, say Home Depot?

[AwwDeOhh]

If there's a fabric store nearby, check and see if they sell burlap fabric (not the same burlap that they sell at Home Depot.. HomeDepot's burlap is for landscaping and not the same stuff).

That is, if you can't get the stuff Glenn mentioned.

Look online. There are plenty of places that sell it.

This is only my opinion, but burlap to me looks pretty low end. Good for making pillows but I myself don't like how it looks on the wall. But yes it would work.

I think I suggested this to you in another thread, use 6" of Safe 'N' Sound for your corner bass traps and 3" for RFZ (reflection free zone) traps. It's the best bang for the buck. You'll have to make frames, but to make it easier have a guy at homedepot cut the wood for you into the sizes you need with the big saw. I used 5/8" melamine. For fabric, go to Fabricland and ask for black broadcloth. It's breathable and affordable.
