Did you hire a third-party contractor to do the sprayed-on insulation or was it part of a new house construction?

Batt insulation comes with or without an aluminum or paper moisture barrier. If you are concerned about trapping moisture, you can buy batt insulation with no vapor barrier. Spraying insulation does not necessarily mean foam. You can also spray fiberglass insulation above the ceiling, which is actually more common than foam.
