Blown-in insulation being applied in attic

Blown-in insulation

Blown-in insulation means filling existing cavities in spaces such as attics with a material that has a high R-rating. Unlike loose-fill insulation, blown-in insulation is applied with a blower machine, leaving less of a mess than loose fill insulation.

Blown-in insulation provides the homeowner with greater control over the quality and consistency of blown-in insulation installation.  Blow-in insulation can be easily installed in confined areas such as wall cavities or attics.  It naturally fills every crevice, void, or cavity for better coverage that loose fill or batt type insulations cannot provide.

 Since blown-in insulation is highly contained when blown into open spaces, it will not settle over time like loose-fill insulation, so you don't have to worry about additional settling after blown-in insulation has been installed.  The best part about blown-in insulation is that it offers better energy savings than batt insulation the blown-in form will not settle like other loose-fill insulations.  Blown-in insulation offers greater overall thermal resistance than other types of insulation.

Blown-in (or also "blow-in") fiberglass, cellulose and mineral wool are the three main types of blown-in insulation.  Typically blown-in insulation is used to fill spaces like wall cavities, attics, and crawlspaces because these areas are difficult if not impossible to properly seal with other types insulation.  Loose-fill material does offer many benefits over blown-in materials such as improved air flow through the cavity which prevents moisture problems.

​ Blow-in insulation does have its advantages over other forms of insulation, being very easy to install as it can be blown into cavities with a blower machine, so you don't need help from another person or special tools to apply it, unlike loose-fill forms which can be heavy and awkward.  
Blown-in fiberglass, cellulose or mineral wool are all ideal for most applications because they are fire resistant with Class 1 flame spread ratings, do not support mold growth, and are inexpensive compared to other insulations.

loose-fill insulation

Loose fill insulation is used in conventional in buildings in both commercial and industrial applications. When applied to the interior of enclosed spaces such as attics or wall cavities, loose-fill insulation provides many benefits that are not given by other types of insulation like rigid foam panels or fiberglass batts. For example, unlike most other types of insulation, loose-fill insulation can adhere to irregular surfaces which makes it an ideal choice for installation in hard-to reach places like tight corners. Additionally, because there's no need to tear open walls when installing loose fill insulation inside wall cavities, you'll never have to worry about exposing your home to mold or mildew again.

Loose-fill insulation is composed of the same substance as conventional, fibrous insulation like fiberglass or mineral wool (in fact, in some cases recycled cotton has been used in place of glass fiber) but comes in a form that only needs to be compressed with hand tools in order to fit into tight spaces.

Loose-fill insulation is usually made using cellulose (shredded newspapers which are then treated with boric acid and formaldehyde) or synthetic fibers such as polyester or fiberglass. Blown loose-fill insulation is blown by machine directly into the space it's being installed in while poured loose-fill insulation must be mixed on-site before it can be poured.

Loose-fill insulation has a number of other significant benefits (in addition to its loose, fluffy consistency) that make it the preferred type of insulation for installation in enclosed spaces like attics and wall cavities. Unlike rigid foam panels which require drywall to be placed over them and create an extra layer between your rooms and heated or cooled air, loose-fill insulation can actually enhance the performance of conventional fiberglass batts by providing an air pocket around them which reduces the amount of conditioned air lost through conduction.
