Rock Wool Blanket, High Temperature Fireproof Insulation Roll for Industrial Pipeline & Steel Structure
1. Product Overview
Rock wool blanket, also called rolled flexible rock wool, is bendable inorganic fiber insulation refined from basalt and diabase after high-temperature melting and centrifugal fiber spinning. Distinct from Glass Wool Blanket, it stands out with outstanding heat endurance, flame resistance and mechanical strength, tailored for fire blocking, thermal preservation and sound absorption across high-temperature industrial fields.Supplied in rolled form, the material gets trimmed and bent freely to wrap odd-shaped devices and curved piping. Buyers may pick aluminum foil clad, water-repellent or high-density grades. Focused on high heat tolerance, rust prevention and noise control, these rolls get widely fitted on industrial machinery, hot pipelines, steel frames and kilns to replace regular insulation under severe high-temperature working conditions.
2. Core Product Advantages
Ultra-high Temperature Resistance
Produced from natural basalt ore, the blanket runs steadily under sustained heat up to 700℃, resisting thermal radiation and hot air impact for long-term wrapping of hot industrial gear, pipes and furnace bodies.
A1 Class Non-combustible & Excellent Flame Retardancy
All-inorganic fiber will not catch fire, release toxic smoke or molten drops under intense heat, with no shrinkage during fire to slow flame and smoke spread and satisfy strict industrial fire control standards for high-risk facilities.
High-density Structure for Superior Noise Reduction
Thick compact fiber with heavy bulk density effectively cuts low-frequency noise and mechanical vibration from boilers, large blowers and factory machinery, outperforming lightweight insulation in sound blocking.
Corrosion & Aging Resistance for Industrial Use
Stable chemical makeup fends off acid, alkali, mildew and outdoor weather erosion, tolerating oily fume, damp air and corrosive gas to keep consistent performance on open-air steel frames and exposed hot equipment.
Flexible & Easy to Install
Tear-resistant rolled rock wool bends and cuts on demand, fitting tanks, curved ducts and irregular equipment seamlessly without gaps to speed up field construction on complex sites.
Hydrophobic & Moisture-proof
Specially treated for water repellency, it stops condensate buildup and damp-induced performance drop, suited for indoor factories, outdoor construction and persistently humid industrial workshops.
3. Main Product Types
Aluminum Foil Faced Rock Wool Blanket
Outer aluminum foil brings heat reflection, water resistance, dust proofing and anti-radiation protection, ideal for uncovered high-temperature equipment, external steel frames and outdoor pipeline insulation.
Hydrophobic Rock Wool Roll Blanket
Enhanced waterproof treatment guards against moisture damage, a practical choice for damp factory equipment, heat exchange areas and outdoor construction works.
Plain Rock Wool Blanket
Cost-effective standard roll with reliable high heat resistance, commonly embedded inside walls or wrapped on hidden indoor hot machinery for heat and sound insulation.
4. Technical Specifications
Available densities cover 80kg/m³, 100kg/m³, 120kg/m³ and 140kg/m³, while regular thickness ranges 30mm, 50mm, 75mm and 100mm. Standard roll width comes in 1000mm or 1200mm, with working temperature spanning -20℃ to 700℃ and official A1 non-combustible fire rating. Core strengths include high-temperature endurance, flame retardance, corrosion resistance, low-frequency sound insulation and flexible rolled layout.

Special Equipment Fire Cladding
Fireproof wrapping for production machinery and fire partition setup within high-temperature working zones.
6. FAQ
Q1: What separates rock wool blanket from glass wool roll?A1: Their biggest gap lies in heat resistance. Rock wool withstands ongoing heat up to 700℃ for high-temperature industrial fire insulation, whereas glass wool only fits regular-temperature HVAC pipeline projects.
Q2: Does rock wool work for high-temperature steam pipeline wrapping?A2: Yes. It stays intact under long-time high-temperature baking without softening or failure and serves as preferred insulation for steam and hot industrial pipelines.
Q3: Is this roll water resistant and fit for outdoor placement?A3: Base material naturally repels water and mildew; foil-clad versions further withstand wind, rain and UV damage for years of service on exposed steel frames and open-air hot equipment.
Q4: Why does rock wool perform better at factory noise reduction?A4: Dense thick fiber forms a solid barrier against low-frequency mechanical vibration noise, far exceeding ordinary light insulation for workshop noise treatment.
Q5: Can installers wrap irregular structures easily with rock wool blanket?A5: Its tough flexible roll gets cut and bent freely to hug curved tanks and custom-shaped equipment for tight wrapping and convenient field mounting.
7. Product Summary
Class A fireproof rolled rock wool targets high-temperature industrial insulation, fixing glass wool’s limits on poor heat resistance and weak industrial adaptability. It combines high-temperature tolerance, flame retardancy, corrosion resistance and outstanding low-frequency sound insulation. With foil faced, water-repellent and high-density options ready in full sizes, the product gets widely used on hot factory equipment, steam pipelines and steel workshop buildings as durable roll insulation for all kinds of harsh industrial fire and thermal preservation projects.
