What is the temperature range of Cellular Glass?

• A. - 450°F up to 900°F
• B. - 100°F to 200°F
• C. - 600°F to 1200°F
• D. - 450°F to 900°F

Answer: (A)

Cellular glass insulation can handle a very wide range of temperatures because its closed-cell glass structure stays dimensionally stable and chemically resistant from very cold to fairly hot service. This means it effectively insulates lines and equipment that operate near cryogenic temperatures as well as those that run at high process temperatures. The commonly used operating range is from about minus 450 degrees Fahrenheit up to 900 degrees Fahrenheit. The lower end covers cryogenic or extremely cold service, while the upper end accommodates many industrial processes without the material losing its insulating properties. Narrower ranges, like minus 100 to plus 200, don’t reflect its capacity for cold service, and ranges suggesting up to 1200 degrees Fahrenheit exceed what cellular glass is typically rated to handle.
