What is the R-value of loose fill mineral wool insulation?

The R-value of insulation is a measure of its thermal resistance, indicating how well it insulates against heat flow. Loose fill mineral wool insulation typically has an R-value of approximately R-3.1 per inch. This value reflects the effectiveness of the insulation material in resisting heat transfer, which is crucial in maintaining a comfortable indoor environment and improving energy efficiency in buildings.

In comparison to other types of insulation, R-3.1 per inch is a solid figure for mineral wool, which is known for its fire-resistant properties and sound-dampening capabilities, making it a preferred choice in many applications. This level of insulation helps in achieving energy standards and can significantly contribute to overall energy savings by minimizing heat loss in winter and heat gain in summer.
