r is for r-values . . .
Insulation is measured or rated in terms of its thermal resistance, or R-value. The higher the R-value, the greater the effectiveness of the insulation. The R-value depends on the type of insulation, its thickness, and its density. The greater your R-value, the greater your resistance to heat flow and loss. Its effectiveness also depends on how and where the insulation is installed. If your insulation is compressed it will not provide the full R-value.
There are different R-values based on what might be required for your climate (R-13 for warmer climates and R-30 for colder climates; and for different sized areas (16" spaced studs or joists, vs. 24" spaced ones; and for different applications - if your walls are 2x4, vs 2x6 or even 2x8 construction for example).
We are required to have R-21 in our 2x6 walls, R-38 in our vaulted ceiling and R-30 under our floors per our building code.
