Insulation 'R-Value' vs. 'U-Value'

Video lecture covering the significance of Foam Insulation R-Value and its relationship to U-Value, or the 'reciprocal of R-Value' measured in Watts per Square Meter (W/Sqm) of Insulation Area.  Includes house heating cost analyses' pertinent to Natural Gas and AC Electric heating (2024, U.S.).  Most houses are NOT uniformly insulated at a consistent 'R-Value' nor workmanship.  Heating costs are typically three to five times higher than the calculation made in this lecture.  Or approximately $8 to $12 per day for a 3,000 square feet house, not including taxes and fees.
