What is the k-factor of urethane?

The k-factor of urethane typically falls within the range of 0.12 to 0.16. This measurement is crucial as it indicates the thermal conductivity of the material, directly impacting its effectiveness as an insulator. Urethane is widely used in insulation applications due to its favorable balance of thermal performance and mechanical properties. A lower k-factor signifies better insulating capabilities, as it means the material resists heat flow more effectively. The specified range for urethane is supported by empirical data and material specifications in the field, making it essential for practitioners to understand when selecting insulation materials for various applications.
