What does the R mean in R-value?

resistance
R-Value is the rating system used to grade insulation products or a material’s insulating properties. The “R” stands for “resistance” and refers to the resistance a material has to heat flow, or temperature conduction. When a product or home has a high R-Value, this means it is well insulated.
