Re: Insulate Ducts in Basement?
Since it is forced air insulating the ducts in a basement really doesn't make that much of a difference .... in my opinion.
Some heat will emit from the metal ducting as it's being warmed from the warm air being forced through ....however it does end up in the conditioned space which is a positive.
It would be more feasable to seal the joints preventing air leaking from the ducting which would reduce the amount needed else where.
As for noise reduction .... insulating the outside of the ducting won't do much for noise reduction since mostly the noise heard is usually velocity noise of the air being forced by the furnace blower.
Just a thought.
