What is the R-value of low density fiberglass loose fill insulation?

The R-value of low density fiberglass loose fill insulation is approximately R-2.2 per inch. This value indicates that for each inch of thickness, the insulation provides about 2.2 square feet of thermal resistance, which is essential for understanding its effectiveness in reducing heat transfer.

Low density fiberglass is commonly used in attics and other areas where it can be easily blown into place to achieve a desired insulation level. The R-value reflects the material's ability to resist heat flow; hence, higher R-values mean better insulating properties. Knowing the R-value helps homeowners and builders determine how much insulation is needed to meet energy efficiency goals and building codes.

Other options suggest higher values, which do not accurately represent the properties of low density fiberglass loose fill insulation. Understanding these distinctions is crucial when selecting insulation materials for specific applications.
