Rigid foam board R-value is generally higher per inch than fiberglass insulation. While fiberglass insulation typically provides around R-3 to R-3.5 per inch, many rigid foam boards offer higher thermal resistance and improved moisture resistance. This makes rigid foam insulation boards particularly useful in exterior wall insulation systems where durability and energy performance are critical.
