About Fiberglass Blown-In Insulation
Fiberglass blown-in insulation is applied by machine and used in attic fill, mid-floor and netted wall cavity applications with a well-known ability to seal small spaces and cracks.
What Is Fiberglass Blown-In Insulation?
Fiberglass blown-in insulation, often referred to as blowing wool, is an unbonded fiberglass material that is manufactured in a similar process to fiberglass batt insulation. It is typically designed to be machine applied by mixing the material with air and blowing it into open attic application. Fiberglass blown-in insulation can also be applied in wall cavities using netting.
Fiberglass Blown-In Insulation Benefits
Fiberglass blown-in insulation has a flexible R-value, is able to fill small spaces, has top-notch air sealing abilities, and is effective at reducing noise.
Flexible R-Value
Since fiberglass blown-in insulation is a loose product, it gives the contractor the flexibility in establishing the R-value, in order to suit whatever climate the application is in throughout the United States. The more depth of the material that is applied, the higher the R-value it becomes.
Fills Small Spaces
Another benefit of fiberglass blown-in insulation being a loose product is its ability to fill small spaces during installation. This is a benefit over other standard fiberglass batt insulation products, and it is useful in a variety of applications in both residential and commercial construction types across the U.S.
Reduces Noise
All fiberglass blown-in insulation products are well-known for their ability to seal small air cracks and spaces in any application in all construction types, although attics, mid-floor and wall cavities are the most popular. This provides excellent noise reduction throughout a home or building of any type.
