What does the acronym R-value measure?

• A. Air quality of HVAC systems
• B. Thermal resistance of insulation materials
• C. Sound transmission in ducts
• D. Efficiency of heating elements

Answer: (B)

The acronym R-value measures the thermal resistance of insulation materials. It indicates how well a specific material can resist heat flow, which is crucial for determining the effectiveness of insulation in buildings. A higher R-value signifies better insulating properties, meaning that the material can keep heat from escaping in the winter and prevent heat from entering in the summer. This characteristic is vital for maintaining comfortable indoor temperatures and improving energy efficiency by reducing heating and cooling costs. Understanding R-value is essential for HVAC professionals as it directly relates to the performance of HVAC systems and the overall energy efficiency of a structure.
