how thin can a duct be?

darindApril 3, 2011

Hi,

I am doing a basement remodel. We have one branch line duct we have to run on the bottom of the joists for about a 5 foot length. Unforntunately, it is in the middle of the basement. Currently this duct is 3.5x10. 35 sq inches.

As basement height is an issue, I would like to minimize the thickness of this duct.

Is it resonable to get a custom duct that would be 1.5x24 (36sq inches) or 1x36 inches?

Its the perimeter that counts, but round is the most efficient...I'd do it, but assure that 36 inches overall is sufficient....so length matters, as well as the size of the rooms, insulation, and comfort levels..
Too small may result in noise...
A poly material may have less friction.
This becomes complicated, does it not ?
We are only considering a 5 foot run, so worry not.
I did learn something at school years ago...
