Hey, this could be a stupid question but I got some Pink Panther R-13 fiberglass batt for cheap at Home Depot and I was thinking about putting this under my existing vinyl floor in my GMC Sierra as a sound barrier. It would go above my sound damper and between the stock jute and vinyl floor. Nobody has seemed to try this as a sound barrier and I'm not totally sure why. It seems like it will block road noise very well. My question is is this a terrible idea? Will I be choked out from the fiberglass smell or something? Does it not work in a vehicle application? Any ideas?
