Eagle Panel Systems manufactures panels with 4 different thicknesses of Expanded Polystyrene (EPS) cores, which determine the R-Value of the panel.
3 5/8" EPS Core = R-17
5 5/8" EPS Core = R-25
7 3/8" EPS Core = R-34
9 3/8" EPS Core = R-41
9 3/8" High Density EPS Core = R-45
Check your local building code for minimum R-Value requirement.
