Combined Cycle (CCPP) & Thermal Power Plant Insulation
ERATHERM delivers complete, turnkey insulation for combined cycle (CCPP), thermal, biomass and cogeneration power plants — covering gas and steam turbines, HRSG systems, boilers, stacks, pipelines and auxiliary units. From thermal calculation and material selection to scaffolding, application and commissioning, every scope is engineered under one roof to EN and ISO standards. With 20+ years of experience and a reference portfolio exceeding 15,000 MW across Türkiye and Europe, we are one of the energy sector's most trusted insulation partners.

The Critical Role of Insulation in Power Plants
Power plants are among the most complex facilities in industry, managing high temperatures, pressure, vibration and demanding process conditions at once. Insulation here is far more than heat-loss reduction — poor design or unsuitable materials can:
- Create high energy losses and disrupt process balance
- Increase maintenance costs and unplanned downtime
- Put personnel safety at risk through hot surfaces
- Cause corrosion and mechanical deformation in equipment
ERATHERM designs systems that deliver optimal performance using world-standard engineering principles across every project — treating insulation as a multi-disciplinary engineering service.
A Closed-Loop Cycle of Engineering & Execution
Engineering, material supply and turnkey application combined in a single delivery — from feasibility through to commissioning.

Engineering & Thermal Calculations
Heat-loss calculations, thermal conductivity analysis, thickness optimization, temperature profiles, high-temperature expansion analysis and HRSG-specific calculations.
Detail engineering
Project Design & Detailed Engineering
Insulation detail drawings, technical specification development, installation methodology, optimal material selection, cladding and support-system design.
Specifications & BOM
Material Supply
Rock and glass wool, high-temperature ceramic fiber, cellular glass, aerogel, stainless / galvanized / Alu-Zinc cladding, jackets, industrial adhesives and fasteners.
Insulation materials
On-Site Application
Gas and steam turbine insulation, HRSG, boiler and stack insulation, pipeline and equipment insulation, economizers, reactors, acoustic and cold/cryogenic systems.
Turbine insulation
Scaffolding Systems
Much of the insulated area in power plants is at height — so safe scaffolding installation, engineered access platforms and mobile/fixed access solutions are integral to the service.

Quality Control & Testing
Thermographic analysis, condensation control measurement, insulation performance tests, cladding inspection, torque/connection tests and commissioning support, to EN and ISO.
Inspection & supervision
Where Gas & Steam Turbines Share One Process
CCPPs are highly efficient plants where gas and steam turbines operate within the same cycle — meaning high temperatures, high vibration and continuous load variation. ERATHERM specializes across the full CCPP scope:
- Gas turbine: hot casing, exhaust diffuser, compressor outlet lines, expansion joints
- HRSG: economizer, evaporator, superheater lines, stacks and chimneys
- Steam turbine: jacket systems and spray + jacket combinations
- Auxiliary: BOP, fuel-gas, lubrication, fire-protection and cooling-water circuits
High-Temperature Insulation up to 600 °C
Thermal power plants involve some of the highest process temperatures in industry. ERATHERM produces the most reliable solutions for boiler bodies, mills, electrostatic precipitators, flue-gas lines, economizers, heat exchangers and ash-handling systems, where material selection and detailing determine plant lifespan.
- Special insulation techniques for service up to 600 °C
- High-density rock wool and ceramic fiber systems
- Special cladding engineering for harsh flue-gas environments
- Cold & cryogenic and acoustic systems where required
