Blanket, or batt, insulation can be manufactured using fiberglass, mineral wool, or cotton. Fiberglass is made primarily from silica spun into glass fibers held together with a phenol-formaldehyde (PF) binder— although formaldehyde-free products are commonly available. Most fiberglass insulation today has at least 30% recycled-glass content, with some manufacturers using as much as 40% post-consumer recycled glass from bottles.
