How to Use Fiberglass Blown-In Insulation

Fiberglass blown-in insulation is typically used in attic fill, mid-floor and netted wall cavity solutions. Due to its excellent ability to seal small air cracks and spaces, fiberglass blown-in insulation is also an effective product for reducing noise throughout a home or commercial building.

Fiberglass Blown-In Insulation R-Values

Fiberglass blown-in insulation is flexible in establishing an R-value. The depth of the installed material determines the R-value. (R-value requirements are governed by the Authority Having Jurisdiction (AHJ) in each state or municipality. Please check with your AHJ to determine the correct code for your area.)

Different regions require different levels of insulation.This map shows the most cost-effective levels of insulation for the different climate zones in the U.S. Based on your zone, use the table to find out how much insulation you need. The higher the R-value of insulation, the more thermal insulating capacity it has. Zones 1, 2, and 3 make up the southern portions of the U.S. and have an average suggested minimum insulation rating of R-30 in attics and R-13 along floors. Zones 4 to 7, which cover the northern half of the country, suggest that attic insulation have a minimum R-38 rating and floor insulation have a minimum R-25 rating.

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.
