Will the insulation help with reducing sound between rooms? Looking to install this in return air...

Will the insulation help with reducing sound between rooms? Looking to install this in return air that runs between above-garage-apartment and the main house through the attic and want to make sure sound doesn't carry from one room the the other.
Asked by: Landlord
We installed this under our kitchen floor and don't hear a thing from it. Of course there is R 30 insulation under the floor.

can i use this for hot air outlet on a wood furnace

can i use this to connect hot air outlet of wood furnaces to oil furnaces. i'm running black stove pipe for the first couple of feet out of the hot air outlet of furnaces then i was going to use this for the rest. can it take the heat from the furnaces being that close to it
Asked by: fiberman38
Absolutely not. This is designed to carry cold or hot air only, not flue gases. The interior is a metal coil covered in plastic foil which would probably melt or even catch fire from hot flue gasses.

Can this be used for the inlet side of a Furness or will it collaps?

Asked by: Mike
Thus is merely a duct. Your intake plenum should take the initial force. As long as airflow is not restricted, no duct should collapse, including this one.
