Industrial Insulation Group (IIG) was formed in 2002 as The Calsilite Group and Johns Manville Corp. merged the manufacturing capabilities for several high profile and widely used product lines serving North American and global industrial insulation markets. Thermo-12® Gold Calcium Silicate, Sproule WR-1200® Perlite and Super Firetemp® Fireproofing were the most recognizable brands for use in elevated temperature processes and fireproofing in the refining, petrochemical, power generation, pulp and paper, metals manufacturing and other sectors.

The IIG product offering was expanded further in 2003 with the acquisition of mineral wool manufacturing and the MinWool-1200® brands of pipe, board and blanket insulations. This addition also brought the company further into mineral wool applications for sound and fire protection featuring MinWool Sound Attenuation Fire Batts (SAFB), Safing, and Curtainwall insulations.

As part of the company’s global perspective and commitment, a joint venture was formed in 2005 resulting in the manufacture of quality calcium silicate insulations under the IIG Shanghai banner in China.

Continued growth led to the acquisition of Mineral Products of Texas in late 2006. The MPT family of Pre-Formed, Precision Cut and Field Pre-formed pipe insulations effectively complements IIG’s overall portfolio of products. Also, this Houston based facility brings capabilities that include mineral wool Metal Mesh Blankets and Pipe and Tank Wrap as well as fittings from mineral wool and calcium silicate.

As a result of this on-going strategy, IIG now operates from six manufacturing plants located in Georgia, Louisiana, Colorado, Alabama, Texas and China. Together, these plants provide customers with quality proven insulation products which are upgraded and enhanced through contemporary technology.

At IIG, we are committed to safety; this pervades our organization and extends to our clients, our colleagues and our industry. We are dedicated to empowering your personnel to make safe choices, strengthening the safety of your process, and protecting our planet. Proper material selection greatly improves efficient use of energy and the industrial sector’s carbon footprint in North America and the world. 

IIG knows that designing insulation systems can be complicated and involves taking many factors into consideration. We create and present educational modules, technical bulletins and product updates to educate designers and encourage discussion regarding design parameters and solutions.
