The insuolation is black vs regular fiberglass color and it smells like perfume. I ran the fan thru it for 3 weeks and it still smells like perfume? Why is the insulation black and what was sprayed on it to give it the odor. I am going to have to remove the plemum, scrape off the black insuation and reapply new insulation. Appreciate any comments
