We have not been in her house. But based on our heating bills and the amount of heat loss through these cinder block/formstone/drywall uninsulated walls of this house...we guess her new house probably has a layer or two of insulation in it.
Recently I purchased some liquid soap, and within two days it looked like this.
It does not like the cold either, and separated out. Bar soap in the wintertime in this house. Plans to knock down next year and rebuild.
