YES, what you want is rockwool or Corning 703 insulation and you can make the panels, see youtube for the DIY videos, it will work very well. See:
Would this work s a cheap way to experiment with room treatment?
(The title was a typo I cannot edit, my keyboard is worn out & I cannot type and look at the screen while I type. The title should say: "Would this work as a cheap way to experiment")
. . . and I am cognizant that this wouldn’t be better than the real deal, but would it do anything as far as sound absorbency goes?
At Lowes they sell these giant (4’ x 8’) insulation panels that are made of a solid material, as opposed to the rolls of soft material. But I was looking at them (the hard panels) and they don’t feel at all absorbent--they feel like if anything they would be reflective.
But as I typed that question, how about the stuff that comes in a roll? That stuff certainly appears absorbent. I know that aesthetically both of these experiments would be butt-ugly, but in this small room I could get away with it without taking too much grief.

Thanks, @kota1 , are those that you pictured rockwool or Corning 703 ? That is not what I saw at Lowes. They were smooth on both sides & green. |
I believe you saw xps or “extruded polystyrene” At the depot they are 4’x8’pink or blue boards Not to be confused with eps or “expanded polystyrene” which is usually the white boards that seem to beak off in white beads floating through the air. Neither of these are ideal for broadband absorption but might absorb a touch of bass. I’m guessing most midrange and high end would reflect back but I’ve never tested (measured) with them. I agree with kota 1 just find some owens 703 it will be sold at any insulation supply center.
