natural fiber insulation

natural fiber insulation

Made from animal, plant, and mineral resources. They contain no VOCs (volatile organic compounds) or chemical irritants, have excellent thermal and sound blockage, have the ability to absorb moisture, and can breathe and react to climatic changes. Natural fibers are classified based on their origins. Plant sources are extracted from seeds or seed cases, such as hemp, kapok, and cotton fiber. Wood fibers are made directly from wood and are not inherently moisture resistant, and so must be coated with enhancers or other adhesive materials. Cellulose fiber is made from 80 percent recycled postconsumer paper. Typically it is blown or poured into hard-to-reach areas, such as attics and finished wall cavities. Animal sources contain hair extracted from animals, such as sheep, mohair, and alpaca. Mineral sources either occur naturally or are modified from fibers extracted from minerals. Their visual and performance properties closely resemble fiberglass. They are primarily applied as loose-fill and batting in hard-to-reach areas, or as rigid boards in roofs and attics. Since they are highly fire-resistant, they are also often used for furnace and chimney insulation. See also: Insulation systems
