If you are walking over your insulation, as in it's between the top
most floor's ceiling and the floor of the attic, you might have it
installed incorrectyl.

Now if it's on semi finished walls in your attic, I've seen people put
up like 6 mil poly to keep dust down, and it will work as a vapor and
draft barrior.

Just guessing, since I can't see your installation. Got photos?

It's just regular wall insulation. Floor is covered with floorboards. I
just didn't know if a vapor barrier was acceptable or not. Someone else
mentioned perforating the covering.
