Unfaced insulation is ideal for new construction, remodels, and interior walls, floors, ceilings, basements, attics, and crawlspaces that do not require moisture control.
Attic insulation should generally be 10 to 14 inches thick, depending on the R-Value needed for your region.
Mold on insulation often appears as black, brown, or greenish discoloration and is accompanied by a musty, dank odor.
