The Insulation Types Our Machines Use and Why They Work

September 25, 2014

At Capitol Machine, we specialize in manufacturing loose-fill insulation machines and believe the most reliable kind of insulation is blown-in. Our machines utilize various insulation types, including fiberglass, cellulose and rock wool. Here is a breakdown of each type we use and why they work when insulating homes.

Fiberglass Blown-In Insulation

Fiberglass Insulation with Capitol Machines

As we mentioned in our fiberglass article, this type of insulation is most commonly used by contractors. Loose-fill fiberglass is created from recycled glass and spun into fibers. According to the U.S. Department of Energy, fiberglass is made out of at least 25 percent recycled material. It is a reliable insulation option for homes because it creates an airtight barrier when blow-in, saving energy and your customers money year after year. Fiberglass works well in attics and crawlspaces because it can guard against moisture and mildew.

Cellulose Loose-Fill

Cellulose insulation is made out of recycled newspaper, cardboard and plant fiber. It consists of at least 75 percent recycled content according to the U.S. Department of Energy. Three main types of blow-in cellulose insulation are used, including loose-fill, stabilized, and wall-cavity spray. Some of the main benefits of cellulose are that it is non-toxic, does not conduct heat and it is the least polluting. Like fiberglass, blow-in cellulose fills in the cracks and crevices to create a thermal barrier from the outdoors.

Blow-In Rock Wool

Rock wool is a naturally-occurring mineral fiber that is made from strands of heated rock or minerals. The U.S. Department of Energy reports that this type of insulation consists of 75 percent recycled content or more. According to the National American Insulation Manufacturers Association (NAIMA), “Loose-fill rock and slag wool resists settling…so that the installed thermal performance is maintained over the life of the product.” Rock wool is commonly used in attics, walls and ceilings. It resists moisture and blocks out air leaks.
