Which term best describes a building property that influences heat transfer through walls and insulation?

• A. Physical
• B. Chemical
• C. Thermal
• D. Mechanical

Answer: (C)

Heat transfer is a thermal phenomenon, so the property that best describes how a building material affects that transfer is thermal. Thermal properties cover how materials conduct heat, resist heat flow, and store heat—things like thermal conductivity, R-value (thermal resistance), and heat capacity. These determine how quickly or slowly heat moves through walls and insulation, which is exactly what this question asks about. Physical properties is a broad category that includes many attributes not specifically about heat transfer. Chemical properties relate to composition and reactivity, not how heat moves. Mechanical properties deal with strength and deformation under forces, not heat flow. Hence, thermal is the precise term for describing building properties that influence heat transfer.
