An aged R-value refers to the thermal resistance of insulation or building materials after they have been in place for a period of time, typically several years. It takes into account factors such as settling, compression, and degradation that can occur over time, resulting in a reduction in the material's ability to resist heat flow. The aged R-value is a more accurate representation of the actual thermal performance of the material in real-world conditions.
