Good point, I thought the metal foil stuff was ok.

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.
