Basically, R values range from 1.5 to 7, and the higher the number is, the more effective the insulation sheet is at increasing thermal efficiency, and thereby, insulating your home. Within the R value of insulation, there are three kinds of R values that are commonly used to more specifically measure heat flow resistance variables:

When you compare EPS and XPS insulation at the same R-values, EPS most other insulation materials both EPS and XPS are good at keeping moisture out

The R-value is the measurement of the The federal R-Value Rule prevents insulation salespeople from taking credit for the R-value of adjacent layers in a building assembly (for example, the R-value of an adjacent air space) unless advertising materials clearly state that the claimed R-value is an assembly R-value, not a material R-value. 8 rows 2020-12-07 2017-05-29 EFFECTIVE R-VALUES FOR BATT INSULATION* *Derived from ASHRAE document “Heat Transmission Coefficients for Walls, Roofs, Ceilings, and Floors” 1996 “Good” “Fair” “Poor” Measured Batt Thickness (inches) Effective R-value (2.5 per inch) Effective R-value (1.8 per inch) Effective R-value (0.7 per inch) 0 0 0 0 1 3 2 1 2 5 4 1.5 One area where effective U-values are commonly misunderstood is tapered insulation for low slope roofs or at the eaves of sloped roofs. This bulletin presents the theory and calculation methods used to develop tables of effective R-values for tapered insulation. This shortcut significantly reduces the R-value of the insulation layer, lowering the overall performance of the assembly. For example, a 2×6 at 16” oncentre wood stud wall with R24 batt insulation has an effective R-value of 18.35 (a 23.5 per cent loss of R-value). Fiberglass is assigned an R-value of 3 to 3.5 per inch.

First of all, let’s discuss what R-Value is. R-Value measures a given insulation’s ability to stop heat transfer through conduction. Materials like fiberglass and cellulose may achieve a high R-Value but will still allow air to pass through it. This movement is actually heat transfer through convection.
