The 3.5 inch thick R-15 insulation offers 36% more R-value compared to the standard R-11 fiberglass insulation. It features a kraft facing that must not be exposed as it can burn.

If your insulation becomes wet, it's crucial to remove and replace it promptly. Wet insulation can significantly lose its effectiveness and may also pose health risks due to potential mold and mildew growth.
