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.
