Oh, I don't know about that stuff. But I guess if you are treating
the basement space as habitable, why insulate between it and the first
floor? You could include the basement space in the thermal envelope
and insulate its boundary.

It's 'unfinished', meaning not insulated, and not heated(zero vents).
It's typically 10 degrees colder than the house. So the house came
with the floor joist area insulated, and made sense, I have warm
floors.

As for habitable, washer dryer, work area and computer is down there.
I tend to work with a jacket, and have not immediate plans to insulate
or heat the space.

I just did a little search and found this from DuPont:

9. Can DuPontT TyvekŪ be used in attics? On roofs? Under Floors? On the
interior?


In 2006 DuPont introduced TyvekŪ AtticWrapT, a unique, breathable membrane
that helps create an airtight seal to reduce air leakage and energy loss
through the roof. All other DuPontT TyvekŪ products in Canada and the US
have been tested and approved as a product to be installed behind exterior
walls.
