Our house is 150yo stickframe/clapboard on a fieldstone foundation.
In the basement, I notice that there is some cold leakage around the
mudsill (i.e., about 10 inch space between the top of the stone
foundation and the bottom of the floorbords)

I have been filling in cracks with a combination of hydraulic cement
and/or caulk.

But I was wondering whether it would additionally benefit to staple
some narrow insulation bats along the mudsill.
Is this likely to be helpful?
If so, can I use regular fiberglass bats? With or without vapor
barrier?


I'd use paper-backed, because I don't like exposed fiberglass.
The fact that it's a vapor barrier is more or less moot, since
you'll have exposed edges.
