Industrial Insulation Types

Properties of Insulating Materials

Form: B = Board, T = Tube, R = Roll, S = Sheet

Insulation properties are compared at 75º F to ASTM standards. Insulation properties vary depending on the operating temperature of the system being insulated. Call for an accurate insulation value for your specific use.
