Fiberglass insulation available as blanket-like batts is the industry standard. It's actually glass, spun into long fibers, then woven and coated with a binding agent. Now available with 30 percent or more post-consumer recycled glass, fiberglass comes as loose-fill and as rigid boards. Fiberglass batt insulation is popular because it's relatively easy to install, and batts are manufactured to fit the standard spaces between studs. Fiberglass is resistant to both fire and mold and tiny amounts of moisture have little effect on its R-value.
