What unit is used for the temperature range of Cellular Glass insulation?

• A. Fahrenheit
• B. Celsius
• C. Kelvin
• D. Rankine

Answer: (A)

The key idea is that insulation product specifications, especially in the US building market, are typically expressed in Fahrenheit. Cellular Glass insulation data sheets often list service temperature ranges in Fahrenheit because this is the familiar unit for builders, installers, and codes in that market. Celsius or Kelvin are the standard in scientific contexts and SI-based standards, while Rankine is mainly used in some thermodynamics calculations and isn’t commonly used for practical product ratings. So, for interpreting the temperature range of Cellular Glass insulation in most US contexts, Fahrenheit is the unit you’ll see.
