Hi!
Going to help a friend with cold floors on the first floor of his home. We plan to insulate the floor from below by accessing the unfinished basement.
My question is what type of insulation? Foil or paper? Also, thinking r19. Any suggestions? His house is in upper Westchester NY.
Thanks!!

Ballon wall constrution, old leaking windows, almost no insulation in the attic, may or may not even have insulation in the walls, non T X G 1 X6's or hardwood installed with no subflooring?
God I love an old house, ching, ching. All I see is dollar signs.

if the basement is conditioned (heated), fiberglass is ok, but roxul is better. if the basement is not conditioned and you can get to flat floor joists, fill them w/ batting if you want to and then cover them w/ rigid foam and tape/goo the edges. any batting in between joists leaves their edges cold, and you could get condensation on them. the rigid foam prevents that.

Wow.. Ok. Not sure if he wants to spend the money on the foam... Thanks!
