Fiberglass insulation won't catch fire, but at a high enough temperature, it will melt. However, the kraft paper that is usually attached to the batting as a vapor barrier can catch fire. Blown-in fiberglass is also considered non-flammable, but installation requires specialized equipment.
Fiberglass is the most common insulation used in modern times because of how it is produced, by effectively weaving fine glass filaments into insulation, fiberglass reduces heat transfer, the main disadvantage of fiberglass is the danger of handling it. Since glass fibers are carefully woven with
Glass wool is a plate-shaped product that is processed by centrifuging molten glass into fibers and solidified by adding an environmentally friendly formula binder based on thermosetting resins. The slender glass fiber has a low thermal conductivity and can trap air well, thereby playing the role of
