Rock wool blanket is a resilient, flexible roll insulation product crafted from spun basalt rock fibers. Engineered for superior thermal management in high-temperature environments, it combines exceptional heat resistance with easy handling and installation.
As a premium inorganic material, it serves as a cornerstone for energy efficiency, thermal insulation, fire safety, and acoustic comfort in modern construction and industrial applications worldwide.
Unmatched High-Temperature Stability: Designed to withstand continuous operating temperatures typically up to 750°C (1382°F). It will not melt, drip, or support combustion, providing reliable insulation and fire protection in extreme conditions.
Superior Flexibility & Conformability: The blanket is flexible, felt-like structure allows it to be easily wrapped, cut, and fitted around pipes, vessels, ductwork, and equipment of any shape or size, ensuring seamless coverage and minimizing thermal bridges.
Excellent Thermal Insulation: The low-density, open fiber matrix effectively traps air, providing high thermal resistance (R-value) to significantly reduce heat loss or gain, improve energy efficiency, and protect personnel from hot surfaces.
Lightweight & Easy to Install: Significantly lighter than many refractory materials, it reduces structural load and simplifies handling. Can be quickly secured with wires, bands, or adhesives, lowering installation time and labor costs.
Low Heat Storage (Thermal Lag): Heats up and cools down quickly, allowing for faster process cycling and improved temperature control in furnaces and ovens compared to dense refractories.
Exceptional Acoustic & Vibration Damping: The fibrous structure absorbs sound energy and dampens vibration, making it effective for noise reduction in industrial facilities and HVAC systems.
Chemical Stability & Corrosion Resistance: Inert and non-corrosive to most metals. It is resistant to oil, solvents, and most chemicals, ensuring long-term integrity in harsh industrial environments.
Industrial High-Temperature Insulation:
Furnaces & Kilns: Back-up insulation for walls, roofs, and doors in steel, ceramic, and glass industries.
Power Generation: Insulation for boilers, turbines, heat recovery steam generators (HRSG), and exhaust systems.
Petrochemical & Refining: Insulation for reactors, catalytic crackers, distillation columns, and high-temperature pipelines.
Pipe & Vessel Insulation:
Ideal for insulating large-diameter pipes, exhaust ducts, flues, chimneys, and storage tanks (both hot and cold).
Fire Protection:
Fire barrier wraps for structural steel, cable trays, and penetrations to maintain fire compartmentation.
HVAC & Appliance Insulation:
Insulation for commercial/industrial air handling units, heaters, and domestic appliances.
Marine & Offshore:
A1-grade fire insulation for engine rooms, bulkheads, and decks.
