Bonded Logic 'Ultratouch' - Better than OC 703

You can certainly make panels from it. Make the frames a little shy (maybe 1/16) and it will friction fit. Some people even just hang it loose from the ceiling.

When I said solid, I meant cut into triangles and stack or double to quadruple the thickness for a good 'old school' bass absorber. Thickness is still king. Trust me, a 2'x2'x2' cube of this in each upper tri-corner does a good job.
 
Bpape - Have you used both 703 and this stuff? If so, does the UltraTouch perform as well or better than the 703? Forget the rigidity, just performance wise?
 
I am trying to figure out how much it weighs.
Since I am mounting a bunch on the ceiling I wonder how the weight compares to the fiberglass? (particularly at 5.5 inches)
I have tried to navigate a few sites to see but have not found the weight factor.

I have not put my ceiling joists up yet so if I need to go with 16 inch spacing to accomodate the extra weight I will.

^^^^^^^
look at the bottom of the page... it gives the weight per bundle...
 
Yes. I've used them both along with 4, 6, and 8lb mineral wool. Also used 3lb and 6lb bonded acoustical cotton.

It's different. To compare 5.5" cotton and 5" or 6" of 703 they would be very close. 6" of 703 is pretty tough to beat. If you're going solid, you can give up the density for the thickness. When you stack it up, you can also compress it a bit to get more density as you desire. If you take the 1.2lb UltraTouch and compress it to half it's size, you have 2.4lb, compress by 1/3 and you get about 1.8lb.

If I was going to just do 4" across a corner, I'd stick with 703 or 705. As I said, it really depends on the application.

In the higher density thinner stuff, the 703 is more cost effective. The 3lb cotton does a better job down lower by a bit. It also has zero issues with 'grazing' at shallow angles of incidence.

To throw a wrench in the works, I'm negotiating right now with the original patent holder for the cotton process for some custom products in 2lb and 3lb densities in 3 and 4" thicknesses at very attractive prices. It will be easier to cut and be available in 2'x4' pieces. Stay tuned.

hehe, stay tuned...

Sounds good Bpape. All I know is if the UltraTouch (and similar products) are even close to as good as the 703, then I MUCH prefer using an environmentally safe material such as this. It is worth the slight loss of performance to me.

<waiting to hear back bpape on your stuff...>
 
I probably will get some. I could use some for a corner to fill. I've allready have a few bass traps and the front wall done. I need some more for the ceiling wall junction. It seems so much easier to use 703/705, but everyone is out locally. I don't want to make a frame. Just trying to figure the best way
to make a panel.

Rigity makes no difference as long as it is in a frame or secured somehow. Hell, you may be even able to glue this stuff to a 2x4 piece of plywood and just hang it on the wall as it is. Just because it is not stiff does not mean it will be more difficult to work with either. I've never heard of rigid acoustical foam. :confused:
Tonio, why dont you check it out, maybe even buy some if you plan on making any panels.

Isn't it better acoustically than 703. Being .95 at 125Hz and over 1.00 above.
 
Brian. If you manage to negotiate that with the patent holder, is there any chance of getting a batch shipped over here? :D
 
Sure. Anything can be done for the right price ;)

Seriously, I have no problem doing that but the shipping is going to be outrageous.
 
Brian, I must have missed something here... do you sell Ultratouch?
 
I am also a tad confused but a I think he is negotiating with the manufacturer to get the information so that he can make his own material? :confused:

I just talked with Bryan and he says he does in fact carry Ultratouch, as well as OC 703 and mineral wool... you can check out his website here.

He charges $133.50 for 4 pcs of Ultratouch at 5.5"x24"x94", which includes shipping to anywhere in the continental U.S.

Just trying to help ya'll out. ;)
 
I currently have the UltraTouch. I am negotiating with the patent holder for the cotton process (NOT Bonded Logic) to get a better variety of materials available to me. They're willing to make the cotton in various sizes and densities at my request. I'm looking into being able to have 2lb 4" and 3lb 4" cotton available as well as 6" 1.5lb. For refrerence, the UltraTouch is 1.2lb density.

The biggest thing I like is that I'll be (hopefully) able to give the bulk pricing on 2'x4' pcs instead of having to buy a whole bale. We'll see how it goes. It will likely still be a few weeks until I know more.

The patent holder and manufacturer tells me that they've improved the process and that the new material will be much easier to work with and cut.

Bryan, I am needing to get some of this stuff pretty soon. 5.5" is fine by me, but I like the idea of the newer stuff being easier to cut. Any ETA? If it is too long, I may just go ahead and buy the old kind you already have.

Any thoughts on stacked wedges of mineral wool vs. stacked wedges of compressed cotton in a corner stacked to the ceiling? Easy of use; performance? This is the big thing I am mulling over right now.

Edit: duh, you said a few weeks before you know more. Sorry :o

Keep us posted on the new stuff that is easier to cut and work with. I am in no rush since I just did my panels and still have 8 sheets left to work with of the 703. I would like to see the new stuff when available ;)
 
Bryan. Have you tested the ultratouch, and are the coefficients correct? I think it was apl who said he didn't believe that they would be. If you have not "tested" them, have you at least compaired them to the others? How are they? Is there any way I cud get a load of the new stuff shipped cheaply? What if i bought in bulk? I mean huge amounts then started up a business making absorbers? Would this be a good idea? I'm not sure i could afford to buy in huge amounts though :( I'm a student.
 
I'm sure we can work something out.

As for testing, no. I have not personally had the material tested. I do feel the coefficients are correct as per standard testing. Remember when you do standard testing, there is a lot of edge showing that is not calculated for surface area when doing the sabines per square foot calculation. This can be misleading but it's at least standard to everyone so it is an apples to apples comparison.

I've used the material a lot in home theaters and recording studios. I will tell you that there is a definite hump in absorbtion that corresponds to the numbers shown. So, at a minimum, they're correct relative to each other across the bands.

Once you begin to think about solid absorbers, to me, this is a no brainer. If you can only do 4" thick straddling a corner and you don't need the 'hump' stick with 8lb mineral wool.

One thing this material is great for is in building soffit absorbers. It's very cost effective and very effective across the band and down relatively deep into the subwoofer range when used in appropriate thicknesses.
 
I wanted to follow up to see what the status of the "new stuff" was Bpape.

Also, is there anyone else out there that is currently using this stuff for their applications. I will be needing to get some more treatment materials in the not so distant future and remembered this thread and wanted to check in to see if anyone had much experience with it.
 
I've not gotten anywhere with the manufacturer. They're wanting more volume than I can do as a small guy. I thought we had something going for a while but no-go at this point.
