Floor Insulation
When exploring floor insulation, the surrounding space needs to be considered. For example, "heat loss through an uninsulated floor over a vented crawl space can be significant. Depending on the size of your home, you can save $50 or more in heating costs each year by insulating your floor.

"Do not insulate your floor if the crawl space is not well-vented (it should have at least two vent openings to provide cross ventilation), or if the floor is over a heated space, such as a finished basement."
Just remember: floor insulation is intended to keep drafts out. By itself, floor insulation will NOT change the temperature of your house. Cold air sinks and warm air rises. By minimizing cold drafts entering a room above, you help maintain that warmer temperature, while not changing it.
