Think of it this way: the part of the basement wall that is just below
grade is normally insulated by just a little bit of dirt between it
and the cold air. By installing this insulation wing, you are
improving the insulation of that segment of the wall. The heat
transfer from it to the cold air may still go primarily through the
soil, bypassing the piece of insulation, but that's a longer path.
I'm not saying that this method is as effective as putting the
insulation against the basement wall, but it still is effective.
Cheers, Wayne

If it worked at all it would be the cheapest way to improve R value on
new Construction and would be heavily touted and heavily pushed by
insulation manufacturing companies, you know, the ones that will make
a buck from it, and as well EnergyStar. I have yet to see any adds
from insulation companies, [the ones that profit] or any testing or
testimonials or anything regarding this idea. My logic, of seeing how
dirts mass transfers temps makes me think it wont do anything, ever.
Now against a structure works. If this idea worked why hasnt something
like Pearl lite, or another organic insulator been poured , buried
around houses for hundreds of years. Where is the testing to prove it
works, not theory. Where are the articles that recomend it.

No, I did note that insulation against the basement wall will be more
effective, and for new construction that is easy to do.

Well, for hundreds of years, houses have been designed with soil
bermed against walls for extra insulation in cold climates.

Try a google search on "soil wing insulation". I guess this technique
is most commonly used for frost protected foundations.

Google "frost protected shallow foundation", then come back and tell
us why the IRC, ICBO and all the others are wrong and why it couldn't
work at all. Thanks.
