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

High density fiberglass loose fill insulation typically has an R-value of about R-2.7 per inch. This measurement indicates the thermal resistance of the material, meaning how effective it is at resisting heat flow. The R-value is crucial as it helps builders and homeowners determine the level of insulation needed for energy efficiency in their buildings.

Understanding R-values is essential for proper insulation choice, as higher R-values translate to better insulation performance. In the case of high density fiberglass, the R-value represents a good balance of thermal resistance suitable for various applications, particularly in attics and wall cavities. This choice highlights the importance of selecting the right insulation type based on specific needs and desired efficiency levels.
