Adding 6" of cellulose to the attic will help tremendously, so long as
the soffit vents are kept open with some baffles. You'll add an
average R value of 3.5 per inch of the cellulose so you'll increase
your attic insulation from R-19 to R-40.


Which is what, about 3% difference in heat loss?

Oh, and that's the heat loss through the attic, which is only a
fraction of the whole-house heat loss.

As you can probably tell, I'm skeptical.

Comfort is related to how quickly heat is being lost, and that's difficult
to quantify. But, what if this mysterious comfort goal lies somewhere in
that 3%? It would be a shame not to try.
