GROSS area of a 8"x16" air vent with screening and louvers is 128 sq in.
Thank you......although I don't recall asking, or even what the question is/was....
Maybe he was just venting.
Gross area doesn't mean much - net is what counts.
It's none of my concern, but wouldn't the screening and louvers decrease the open area somewhat?
I have been so advised.

NET area is correct for the Elevation Certificate. I do not know the Net Area. I would have to make an estimate.

The estimated NET area of the air vent would be so noted in the remarks section.

haha...look at the units on that site: 16"X8" covers 124 sq. ft.? more like less than 1 (0.86) sq. ft.
