FIBERGLASS INSULATION

Fiberglass – which consists of extremely fine glass fibers – is an insulation material that is found in most homes.
It is commonly used in two different types of insulation, which are batts and rolls, and loose-fill. It is also available as rigid boards and duct insulation.
Currently, manufacturers produce medium- and high-density fiberglass batt insulation products that have a slightly higher R-Value than standard batts, according to the U.S. Department of Energy. Fiberglass can be placed in unfinished walls, floors, and ceilings. It is fitted between studs, joists, and beams.
Fiberglass is made to slow the spread of heat and cold in both residential and commercial insulation projects. Fiberglass makes for a good option for homeowners looking to save a few dollars or do the installation as a do-it-yourself project.
Fiberglass as an insulator slows the spread of heat, cold, and sound in structures.
The material does this by trapping pockets of air, keeping rooms warm in the winter and cooler in the summer, according to the International Association of Certified Home Inspectors (InterNACHI).
Limiting the amount of air coming into and leaking from a home can work to make a home comfortable. It's important to note that fiberglass limits the air movement, but doesn't stop it completely.

What is R-Value?
R-Value is the capacity of an insulating material’s resistance to heat flow.
Basically, that means the higher the R-Value, the greater the insulating power of the material. While R-Value is something that is good to know, it’s not the revered determiner for all things insulation.
What is Fiberglass Made of?
Fiberglass insulation is made of plastic reinforced by tiny glass fibers.
Fiberglass is made when molten glass is spun into fibers while being coated with a liquid binder. Those pieces are then broken into shorter pieces. Those cooling glass fibers fall onto a moving conveyor belt, piling up into a tangled mess, according to eHow.
The conveyor carries the tangled blanket of fiberglass through curing ovens. Once that process is complete, the batts are cut to the desired length and width.
If the final product is loose-fill, then a binding agent will not be used.
