What IIG Group does

IIG Group (legally IIG Industrieisolierungen GmbH) is a German-based industrial services company founded in 1970 in Gelsenkirchen and headquartered at Ulrichstraße 6. The company specializes in industrial insulation solutions for process industry operators, including thermal insulation for turbines (gas and steam), heat and cold insulation, industrial noise protection hoods, fire protection systems, electrical trace heating, fire doors and smoke control doors, dry construction, and custom-engineered special constructions. Core proprietary offerings include a removable, reusable mattress insulation system (3D-scan-customized, multi-layer seam-staggered, ~40% service cost savings) and a closed spray insulation system with vibration-damping support structure. Custom design work is supported by CAD systems and qualified engineers.

The company operates through 15 locations across 8 countries — Germany (5 sites: Gelsenkirchen, Speyer, Marl, Stade, Merseburg), Czech Republic (Úštěk production site), UAE (Abu Dhabi regional HQ), Egypt (Cairo regional HQ), USA (Fort Myers), India (Pune), Thailand (Rayong), and the Philippines (Makati). It serves enterprise customers including chemical plants, energy producers and combined-cycle power plants, refineries, and pipelines. The company employs over 600 people worldwide (per its own statement of 600+ technical insulation staff) and reports 400+ gas and steam turbines insulated across 309 combined cycle power plants in 54 countries.

The business model is project-based professional services with custom-quoted pricing. Revenue streams are industrial insulation installation, maintenance and repair services, and custom design solutions. The go-to-market is direct enterprise sales via relationship-based account management and international project teams, supported by a corporate website, downloads portal, and career page. The company holds ISO 9001, SCCp, and ISO 45001 certifications along with GSH polyurethane foam and rigid foam certifications, and a German Water Resources Act (WHG) certification valid through 2026. IIG is privately controlled by the Rohrer Group, which acquired shares in 2006, with Werner Kessel serving as Managing Director (Geschäftsführer).
