Finishing room in basement next to furnace. To dampen noise I extended the insulated HVAC pipes beyond the furnace, looped it, to return. I used pink insulation from HOme Depot that suggests this purpose in the ceiling area. I have not yet put in the sheetrock.
I read that for sound you should really pack the insulation in tightly. I read 5/8 is better than 1/2'. I saw some large panels at Home Depot that looked like one inch thick compressed cardboard sold as sound proofing but no one could tell me anything about them. I read about using channels and attaching the wallboard to them.
So, as I am insulating from only the furnace and fan noise, not soundproofing my teenager rock band practice, what would be recommended?
I have a 15 year old daughter who plays club volleyball and it's not uncommon for her to have 5 or 6 friends over night. You can imagine the racket they can make. I can sit and watch TV in the livingroom directly above them in the basement and seldom hear a peep.
I bought the Roxul at Lowes, but it had to be ordered. They don't keep it on the shelf.
