Fiberglass Insulation: What You Need To Know

Fiberglass Insulation – this type of insulation can take on two different forms, Batts/Rolls & Loose-fill insulation. Fiberglass insulation is composed of tiny particles of glass fibers. Glass is melted and spun within a centrifuge to create multiple intertwined glass fibers that make up the insulation. Because this type of insulation is made of glass, it is appropriate to use the proper safety protection to protect your hands, skin and lungs. Batts & rolls can be used in walls, under floors and other various locations throughout the structure. A benefit of batts & rolls is that the insulation rarely settles leaving the R-value intact over the lifespan of the product.

Loose-fill fiberglass insulation is used to fill enclosed cavities in homes & office buildings. This type of fiberglass insulation requires the use of a blowing machine specifically designed for spreading insulation into a cavity or space. Professionals normally install loose-fill insulation to insure proper density is achieved and installment is done properly.

A variation of loose-fill insulation is the Blown-In-Blanket. Blown-In-Blanket insulation is used in wall cavities to create a custom fit insulation solution. Covered non woven fabrics are used to help hold and create cavities for the insulation to be sprayed into. The result is a superior fitted insulation product for your home or office.

A benefit of all fiberglass insulation is that it is made of recycled materials. Usually it is made up of 20-30% recycled glass material, thus making it one of the greenest forms of insulation you can purchase. Finding the right supplier for fiberglass insulation can be a challenge if you’re a contractor. Many contractors get their insulation products from an Insulation Supplier but if you’re a do-it-yourself home-owner you can venture to your local home improvement store for quick and easy jobs.
