What is the R-value per inch for plastic batts?

The R-value per inch for plastic batts is typically around R-4.0. This value signifies the level of thermal resistance that the insulation material provides. Higher R-values indicate superior thermal performance, meaning that the material effectively resists heat flow.

In the case of plastic batts, this R-value is a reliable standard, making it a popular choice for insulation in residential and commercial buildings. When choosing insulation, it’s important to consider not only the material’s R-value but also the overall effectiveness in relation to the specific needs of the space being insulated, such as climate and installation conditions.

Other options suggest R-values that are lower than the recognized performance of plastic batts, which would not accurately represent their thermal resistance capacity. Thus, understanding the proper R-value helps in making informed decisions about insulation selections to ensure energy efficiency and comfort within a building.
