One more diy acoustic panels thread...

I finally got around to it... I´m making half a dozen broadband absorbers.
Here´s how:
First its the frame,

Thats what holds it together (+ glue on the ends of the wood)

Place it on the floor

placed white fabric over the frame (thats gonna be the back of the panel)

then the put the pressed rockwool (75mm thickness) over and press it in, then cut the fabric,

then lay out the fabric for the front of the panel, turn the panel over and place it on there,

then some stapling,

then more stapling, followed by some more cutting of the fabric,

1st off - looks great.

but my question is.. how important is the wood frame around the rockwool???

I'm going to start making my own pannels and I don't understand the need for a wood frame around the absorbtion material... is it just to secure the fabric and make it easier to hang?

Also..

does it HAVE to be Owens Corning?

I called about some Knauf fiberglass panels which I was told have the exact same specs as OC...

would this work?

I´m no expert but yes I believe its to make it easier to hang and to attach the fabric. Many will drill out with a circle saw alot of the wood frame sides to expose more of the wool material.

Great work!
Im building mine very similar, only that i have the wood frame outside. i just think it looks a lot sweeter that way!

The wood frame does help to stabilize the whole absorber. If you only have 1 panel it should work without (i have a few like that), but the corners and sides will start to round a little, there wont be any sharp edges... just not as nice i believe!

Today im building my 2 panels for the ceiling. im also hanging them with the little chain, like you

Spot on. You can wrap 705 but it is hard to mount and IMO does not look half as nice as using a frame. Plus it will last for many years.

Personally, I would not (and did not) make frames that massive.
Fine if you want to, but its not necessary.

The type of frame I built http://www.basstraps.net/DIY-BASS-TRAPS-MADE-EASY.pdf leaves the sides exposed for absorption and ends up being quite rigid while weighing much less.
It's true that the edges of the "big" frame are a bit crisper, but not enough to matter, IMO.
You don't really need the corner brackets. Used 1x2x8 furring strips $.77 each.
And I used Knauf 3lbs per cubic foot, which is the same as 703.
Couldn't post all the pics as some are already here...

My brand new acoustic panels - Similar to these.

I'd like to thank everyone on Gearslutz for getting me motivated enough to build my own acoustic panels. There is SO much amazing information out there these days on acoustic panels! I love it and can't believe it took me 8 years to build these.

GO BUILD SOME PANELS! Your rooms deserve it

I wrote up detailed plans on building your own acoustic panels in a blog post. It's got prices, parts, and tons of photos to help you along the way. I also consolidated lots of useful links to places on the web with others talking about their process!

Most of my process was gathered online from posts like these. I can't thank you all enough for taking the time to post these plans, so instead I thought I'd share my process as well! I used Knauff 3lb. density like RLD did above me.

If you are building panels I highly recommend reading through this post. The panels I built work well for panels, baffles AND a portable vocal booth!
