What does a larger R-value indicate?

A larger R-value is indicative of a greater degree of insulation. The R-value measures the thermal resistance of insulation materials; the higher the R-value, the better the material is at resisting heat flow. This means that materials with a larger R-value provide improved thermal protection, keeping heat inside during colder months and outside during warmer months, thus enhancing energy efficiency in a building. Understanding R-values is essential for real estate professionals when advising clients on home energy efficiency and insulation options.
