Selecting the right ceramic fiber blanket (CFB) saves energy, prolongs equipment life, and ensures safety at the workplace. Being a reliable manufacturer and supplier from Faridabad, BM Enterprises offers an easy buyer’s checklist so you know how to make the right choice without confusion.
What Is a Ceramic Fiber Blanket?
A ceramic fiber insulation blanket is a lightweight insulation material with high-temperature tolerance, which is produced from spun alumino-silicate fibers. It is flexible, easy to cut, and resistant to shrinkage in high heat.
There are three general types:
- RCF (Refractory Ceramic Fiber): Resistant to up to 1430°C.
- AES (Alkaline Earth Silicate): Bio-soluble, easier to handle, suitable for up to 1200–1300°C.
- PCW (Polycrystalline Wool): High-end choice for extreme temperatures close to 1600°C.
Tip: Apply AES for common furnaces, RCF for tougher conditions, and PCW for the hottest areas.
Key Specifications to Check
1. Temperature Grade
Never buy on classification temperature (CT) alone—look at continuous service temperature, which is slightly lower. Common grades are 1260°C, 1350°C, and 1430°C.
2. Density
Measured in kg/m³, density impacts insulation value and strength.
- 64: Light-duty wraps
- 96: Balanced choice
- 128: Heavy hot-face use
- 160: Heavy-duty, high-strength
3. Thickness and Size
General thicknesses are 6–50 mm, widths 610 or 1000 mm, and lengths 7–14 m. Always check tolerances to prevent gaps in lining.
4. Thermal Conductivity
Lower k-values = more insulation. Compare supplier data at various temperatures (200°C, 400°C, 800°C).
5. Shot Content and Fiber Quality
Lower shot content enhances efficiency and decreases dust. Uniform fiber diameter enhances toughness.
6. Chemical Resistance
Where furnaces contain alkali or sulfur gases, or aluminium contact points, look for zirconia-added grades.
7. Facing Options
Blankets can be supplied with aluminium foil, glass fabric, or coatings for hardness, vapor resistance, or erosion resistance.
Compliance and Safety
- AES fibers are bio-soluble and safer for regular handling.
- RCF fibers require stronger safety measures, such as PPE and ventilation.
- Always request MSDS, TDS, and compliance certifications (IS/ASTM, REACH/RoHS). BM Enterprises gives complete documentation with every supply.
Applications of Ceramic Fiber Blankets
- Furnaces & Kilns: Hot-face and backup insulation.
- Boilers & Ducts: Foil-faced versions for pipes and ducts.
- Door Seals & Expansion Joints: Flexible sealing.
- Fire Protection: Component of passive fireproofing systems.
- Automotive & Foundry: Heat shields, covers, and linings.
Installation Best Practices
- Cut with a sharp knife and stagger joints to avoid heat leakage.
- Use anchors or pins for vertical or hot-face installation.
- Do a burn-off cycle to eliminate binders and prevent fumes.
- Jacketing or coatings for protection.
Cost and Value
When suppliers are being compared, compare specifications closely:
- Temperature rating
- Density & thickness
- Conductivity values
- Facing/coatings
- Lead time and delivery terms
A high-quality upgrade blanket can lower heat loss and save 5–8% in fuel expenses, usually paying for itself within a year.

FAQs
Q1. What density is ideal for furnaces?
Ans: 128 kg/m³ is the norm for hot-face lining, with backup at 96 kg/m³.
Q2. Are ceramic fiber blankets safe to use?
Ans: Yes—AES types are bio-soluble. For RCF, wear appropriate PPE and adhere to safety protocols.
Q3. Can I cut and shape the blanket myself?
Ans: Definitely. A sharp saw blade or knife is good.
Q4. How do I prevent smoke during the first heat-up?
Ans: Conduct a controlled burn-off cycle to remove binders before production.
