The R-value per inch of material for fiberglass batt insulation is what value?

Fiberglass batt insulation is known for its thermal resistance, measured in R-value, which indicates how effectively the insulation can resist heat flow. The R-value per inch of thickness for fiberglass batt insulation is typically around 3.2. This means that for each inch of fiberglass batt insulation, you can expect it to provide an R-value of approximately 3.2. This characteristic makes it a common choice in residential and commercial insulation applications, as it offers a balance between thermal performance and cost-effectiveness. Understanding the R-value is crucial in determining the appropriate insulation thickness required for energy efficiency and in accordance with building codes for various climate zones.
