The R Value of a house is a measurement of the thermal resistance of a house. In other words it is a means of measuring how well the house is insulated. This provides a means of reference for how well the house resists changing its internal temperature based on the outside temperature. So I took an attempt at "measuring our house". My side kick Carter and I did an experiment.
