Industrial Insulation Group

Industrial Insulation Group was formed in 2002 when The Calsilite Group and Johns Manville Corp. merged the manufacturing capabilities for several high-profile and widely used product lines that serve North American and global industrial insulation markets. The most recognizable brands from this collaborative effort are Thermo-12® Gold Calcium Silicate, Sproule WR-1200® Perlite and Super Firetemp® Fireproofing, all used in elevated-temperature processes and fireproofing in the refining, petrochemical, power generation, pulp and paper, and metals manufacturing industries.
