Sound absorbing material for furnace
« on: December 11, 2006, 04:22:19 AM »
My fan in my gas furnace generates a lot of noise that is transmited out through the ducts.  I have installed sound absorbing material at the duct exits at the grill areas and it has helped some, but I'd like to attack the problem at the source by installing sound absorbing material in the ductwork right above the furnace.  What material would be appropriate and safe for such an installation.  I assume the material should be rated fireproof?

The foam material to use is at the prices page on the super soundproofing website.  It is fire resistant, (won't support a flame) and can easily be glued on with contact cement.  Click this URL: 
Sometimes it's better th replace the fan with a quieter one, perhaps one that runs slower but moves the same amount of air.  Check with the furnace mfg/dealer to see if it can be upgraded.
