Generated explanation

The illustration shows four separate material samples with their R-values per inch of thickness. Fiberglass insulation is labeled 3.0, concrete 0.08, stucco 0.2, and pine board 1.25. The samples use distinct surface textures, including wood grain on the pine board. The figure compares thermal resistance rather than showing an installed assembly or an installation defect.
