			There are numerous types of fibrous insulation, each having their own benefits and drawbacks. Some common types are:<ref>Energy.gov. (May 19, 2015). ''Insulation Materials'' [Online]. Available: http://energy.gov/energysaver/articles/insulation-materials</ref>
			* '''Fiberglass''': This type of insulation (see figure 1) is composed of extremely fine fibers of glass and comes in rolls or loose-fill. Fiberglass insulation comes in many densities with different associated [[R-value]]s and can be used in areas with limited space for insulation. Fiberglass insulation is made from molten glass that is spun or blown into fibers.

	~~==Types of Fibrous Insulation==~~		* '''Mineral wool''': This type of insulation (see figure 2) is man made and consists of natural minerals or minerals left over from use of molten [[metal]]. It contains a significant amount of industrial recycled content and doesn't require any extra chemicals to make it fire retardant. Mineral wool insulation comes in rolls or loose-fill.

Fiberglass insulation comes in many densities with different associated [[R-value]]s and can be used in areas with limited space for insulation. Fiberglass insulation is made from molten glass that is spun or blown into fibers.		* '''Cellulose''': [[Cellulose]] insulation is made of recycled paper products—such as newsprint. The paper used is cut into small pieces and then fiberized and packed into cavities. Chemical compounds, such as mineral borate, can be added to increase fire resistance.

It contains a significant amount of industrial recycled content and doesn't require any extra chemicals to make it fire retardant. Mineral wool insulation comes in rolls or loose-fill.		* '''Plastic Fiber''': This type of insulation is mainly made from recycled plastic bottles—composed of PET, a type of plastic, and the fibers formed are pressed into batt insulation. Plastic fiber insulation is similar to fiberglass insulation and is generally treated to make it more fire resistant, although it does still melt.

	* '''Natural Fiber''': Some natural fibers including cotton, wool, straw, and hemp are used as insulation materials. Cotton insulation is nontoxic, but is more costly than fiberglass insulation and must be treated with borate to make it flame retardant. Wool must also be treated with borate, but can hold large amounts of water which can remove this flame resistant coating. Wool has a similar R-value as other more common types of insulation. Hemp insulation is relatively unknown and not used widely, but has a similar R-value to other types of fibrous insulation.		* '''Natural Fiber''': Some natural fibers including cotton, wool, straw, and hemp are used as insulation materials.
