I am well aware of how to convert R-value to U. Additional attention needs to be paid to the metal spacer system that is used by Champion versus the TPS used by Schuco. It's proven to be much more energy efficient but the spacer will maintain that for many more years to come. If you take the time to do an SIR over a 10 year period, the difference in profit is significant.
