DIY panels - any reason not to use spray glue?

[AbMagFab]

So I'm making my own acoustic panels (I have too many custom requirements, and I'm handly enough).

After looking at a ton of different designs, I decided I wanted to minimize anything extra beyond just the OC705 material and the fabric. Since I need to strengthen the corners, I'm using some 1/4" foam board.

I've made three (custom shapes), and they look great.

However, to make this work, I used the "spray glue" method, where the fabric is held in place by gluing it to the 705 surface, the sides, and around the back. I'm able to get a nice tight fit this way, and it looks really good. I can also use the light-weight fiberglass hangers (the ones that screw into the back of the fiberglass).

So - Is there any negative to using spray glue? I got fire-treated fabric, just in case, but is the glue permanently a fire hazard? Any other reason not to do it this way?

Thanks!

I used it.

Wouldn't adding a layer of glue on the fiberglass panel defeat the absorption poupose of the panel??

maybe if you only do the sides and back , I'm no expert but that's my opinion.

Using spray glue such as 3m Super77 will have no detrimental effects on the absorbtion of an acoustic panels. Just make sure you get an acoustically transparent cloth and you use a quality material for absorbtion such as OC703/OC705 or something like 8lb mineralboard.

Great, thanks! I'm using OC705 and the black fabric from ATS, and 3m 77, so it sounds like I'm good.

How about any sort of additional fire hazard? Does the glue introduce anything like this, after it's dried? I got fire treated fabric just in case, but I'm curious.

Thanks again!

As far as I am aware the only time Super77 is flammable is when it is actually being sprayed. Once it has dried this is no longer an issue.

Thanks, I appreciate it!

Wall Panel Construction

I would like to make my own panels also. Can you point me in the right direction as far as material and construction goes?

Thanks

Basically:

- OC703 or 705 for the panel material, or equivalent (only reason not to use 705 is price)
- Any fabric you can breath through
- For the frame, you can: do nothing, or use anything you want

There are lots of options and opinions. I wanted the least extra material with my panels, and the lightest panels possible. You kind of need some sort of frame otherwise the OC705 edges will crumble. I chose to use 1/4" foam board, and cut it into 2" and 4" strips, and just framed around the OC705.

I painted the foam board black so it wouldn't be visible, and I sprayed a little on the front of each OC705 panel (flat paint, it doesn't seem to change the characteristics of the OC705) so it wouldn't look yellow through the fabric.

I got my fabric and materials from https://www.atsacoustics.com, and I used the "Rotofast" mounting thingies.

So far it's working great. I just need to kill the screen wall, do one more 4" panel for the back wall, and do two corner traps for the back of my room.

All great advice and right on the money. The other thing is to frame it up with nice wood. Heck if your really good you can make it look like this.
