What is the approximate R-value for one inch of duct wrap insulation?

The R-value is a measure of thermal resistance, indicating how effective a material is as an insulator. For duct wrap insulation, one inch typically has an R-value close to 3.0. This means that for every inch of this insulation, it provides a resistance to heat transfer that reflects its ability to retain or repel heat effectively.

This R-value plays a crucial role in determining how much energy is lost through ductwork in a heating or cooling system. When duct wrap insulation is utilized properly, it helps maintain desired temperatures in the air flowing through the ducts, which enhances system efficiency and comfort levels in a building.

The choices represent common thermal resistance values encountered in HVAC applications, but the typical R-value for duct wrap insulation is widely recognized as around 3.0 per inch, making it an effective option for preventing heat loss or gain in duct systems.
