I just moved to a new home where I tore out carpeting and the pad to put in hardwood floors. I have an unfinished basement which I do use. I would like to know if there is any harm to putting the pad from the carpet in between the rafters in my basement for some heat insulation but mostly for a sound buffer to a noisy freezer. I'll only have enough to do a small section and I would not be opposed to putting several layers in one spot if that cuts down on the sound. I hate to put it in a landfill if I can reuse it. Also, where can I bring my carpeting for recycling, etc? I live in Missouri.
