I just finished installing my new http://www.broan.com/products/produc...4-f9cd6c4efff6
fancy dancy fan heater light. Not to shabby, heater works well. Light works... okay (bit dim), the exhaust fan moves alot of air but it vibrates both joists it's attached to something awful. I hear it in the bathroom directly above and really feel it vibrate the floor. I'm glad it's working at the moment as that means I can keep going in the bathroom but before I put up the ceiling what should I look for with the unit?
I just read some posts that you should use foam around it and it will sound better. I also thought about adding boards fore and aft to try to help decrease the noise. I had planned to put insulation but I have TONS of foam I could spray in. I'll probably call Broan tomorrow too. Any other suggestions on what I should do?
