What is R-naught? R-naught (R 0) is a value that can be calculated for communicable diseases. It represents, on average, the number of people that a single infected person can be expected to transmit that disease to. In other words, it is a calculation of the average “spreadability” of an infectious disease.Insulation ratings are measured in R-values per inch of thickness. An R-value tells you how well a type of insulation can keep heat from leaving or entering your home. Insulation R-values vary based on the type, thickness and density of the insulation material. Typically, a higher insulation R rating means better climate control and better ... Sorted by: 50.
