Products our clients rely on
Engineered industrial insulation trusted by petrochemical, power, and steel plants worldwide.
rock wool
Rockwool Insulation Blanket (Rock Wool Blanket)
Flexible rockwool insulation blanket (also rock wool blanket) for large area coverage, pipe and equipment thermal insulation.
Calcium Silicate
Calcium Silicate Insulation Board
High-strength calcium silicate insulation board (also known as calsil board) with excellent heat resistance and low thermal conductivity. Working temperature up to 1100C. A rigid silicate board ideal for industrial furnace and kiln lining.
Ceramic Fiber
Ceramic Fiber Plus Blanket
Advanced ceramic fiber blanket with improved strength and lower shot content for demanding applications.
Industries We Serve
Solutions Engineered for Your Industry
Select your industry to discover insulation and refractory materials matched to your operating temperatures and performance requirements.
Cement
Advanced insulation products and systems for thermal management in cement manufacturing including rotary kilns, preheaters, coolers, and ducting.
Cryogenic Insulation
Low-temperature insulation for cold chains and cryogenic systems — cold-storage walls, refrigerated transport, low-temperature labs and liquid-nitrogen piping using calcium silicate and glass wool.
Environmental & Dust Removal
Specialized insulation and filtration materials for environmental protection equipment including dust collectors, baghouse systems, and emission control devices.
Iron & Steel
Steel production temperatures reach up to 1600°C. Thermal insulation refractory materials are critical to protecting equipment, reducing energy waste, and ensuring consistent output in blast furnaces, hot blast stoves, ladles, tundishes, and reheat furnaces.
Petrochemical
Rosewool A1 non-combustible rock wool pipe sections, ceramic fiber & calcium silicate for petrochemical plants: 450-650°C piping, furnaces, tanks. CUI-resistant, SH/T3010-2025.
Power Generation
Amid global energy transition and carbon-reduction targets, the power generation industry must balance operational efficiency with safety and environmental responsibility. Rosewool delivers high-temperature insulation for boilers, steam turbines, HRSGs, flue-gas ducts, substations, nuclear facilities, offshore wind platforms and energy storage stations — with rock wool, ceramic fiber and calcium silicate performing reliably from -268°C up to 1000°C and beyond.
Traffic & Fire Protection
Fire-rated insulation materials for building fire protection, cable shaft sealing, and transportation applications meeting international fire resistance standards.
Aerospace & Defense
Lightweight, high-reliability thermal insulation for aerospace and defense — aircraft cargo fire barriers, rocket engine shields, spacecraft re-entry blankets and ship fire divisions.
Building
Thermal and fire insulation for buildings — external walls, roofs, fire compartments, pipe and acoustic systems using rock wool, glass wool, ceramic fiber and calcium silicate.
Concentrated Solar Power
High-temperature insulation for concentrated solar power — receivers, molten-salt tanks and piping, and fire-safety systems using ceramic fiber and calcium silicate.
Green Building & Retrofit
Energy-efficient insulation and retrofit solutions — industrial furnace energy-saving coatings, steel-structure fire wrapping, fire-door cores and partition walls using ceramic fiber and calcium silicate.
Marine & Offshore
Moisture- and corrosion-resistant thermal and fire insulation for ships and offshore structures — deck fire barriers, engine-room piping, LPG tank fire layers and 100% asbestos-free bulkheads.
Nuclear Power
Radiation- and high-temperature-resistant insulation for nuclear power — auxiliary piping, fire compartments, waste storage and valve seals using calcium silicate and ceramic fiber.
