Hi. This is my first posting to this wonderful site, so this makes me the new kid on the block.
I just managed to salvage about 360 square feet of Armstrong "White Nubbie" 3104 rigid fiberglass acoustic panels from our church dining hall remodel. This stuff looks like it must be similar to that 703 stuff. It is yellow 1" fiberglass and has a white textured finish on one side with unfinished edges. It is mostly cut to 4' by 4' but three full 4' x 8' panels were saved. They quote an NRC of 0.95. I'm trying to get a full spec sheet on it. I don't know what the individual are at the standard frequencies. I'm looking for the spec sheet.

Anybody know where I can get the info?
Do you think I "done good"?

I agree with Sword9 that it may be "Armstrong Painted Nubby"
And if so, absorbtion coefficients can be found here

Yes, that's the stuff! It is Armstrong Painted Nubby, only it was originally bought in 4' x 8' sheets. Thanks Sword9 and Z60611.

I'm only in the sketching stage of a nearly 300sq ft studio project. I have everything to learn, yet. I just nabbed this salvage stuff while I could. I think it will come in very useful, don't you think?

I'm wondering if I would use it mostly for resonant panels or for ceiling or what, at this point. Do you guys think that this is worthwhile stuff? It looks like it is similar to the '703' stuff referred to all the time.
