well - title pretty much lays down the question...
We have a 2-story house,
with the family room behind the attached garage,
and above a stone crawl space.
The other part of the house area has a full unfinished basement.

I've had extra insulation blown into the attic area above the family
room,
but have done nothing in the crawl space under the family room.
This room seems to be a couple of degrees "different" from the rest of
the house...
Summer - it's not as cool with the A/C running.
Winter - it's not as warm with the furnance running.

Would laying some insulation in the crawl... help ?
along the sides - from foundation to where the floor meets the sides
under the floor - between the joists

If so - what kind of insulation and what kind of facing -

tnx for any comments - Phil -

Depending on where you are and your climate, you may want unfaced
insulation. With an air conditioned house in a humid climate, vapor
barriers are a bad and no longer needed acording to the new
International Residential Building Code. If you are up north, the
vapor barrier should be on the warm in winter side. Be careful with
adding foam insulation to fiberglass. You may create two vapor
barriers and trap moisture, creating a mold and wood rot problem.
