Choosing a refractory blanket goes far beyond comparing a few numbers and prices. It’s a decision that directly impacts the safety, energy efficiency, and health of your production equipment.
In this article, we don’t just aim to introduce a product; we want to act as a knowledgeable technical consultant, guiding you through 7 key questions. The right answers to these will draw the line between a smart purchase and a costly mistake. Stay with us to avoid the hidden pitfalls when buying a refractory blanket.

Question 1: What Temperature Must Your Refractory Blanket Withstand? (It’s More Than Just a Simple Number!)
Many people only ask, “What is the maximum temperature?”
But the right question is: “How does the blanket behave at its continuous operating temperature?”
Don’t be swayed by the maximum temperature rating. A blanket might withstand 1430°C for a short period, but it will quickly degrade if used continuously at that temperature. The key factor is the continuous operating temperature.
Types of Materials and Their Applications:
- Fiberglass (up to 600°C): Suitable for medium-temperature processes like dryers or steam pipes. It will burn and turn to powder at higher temperatures.
- Silica Fibers (up to 1000°C): An optimal choice for high-temperature furnaces where noise control is also important.
- Ceramic Fibers (up to 1430°C): The undisputed champion for the steel, ceramics, and glass industries, designed for the harshest working conditions.
Klevers Aryana’s Tip:
Our experts don’t just rely on a temperature number. They analyze the complete thermal profile of your process to ensure the selected blanket is perfectly optimized for your specific equipment conditions.

Question 2: How Do the Material and Structure of a Refractory Blanket Affect Its Performance?
“Refractory blanket” is a general term, but the difference between a premium product and a mediocre one lies in the details of its material and construction.
- Needled Structure:
This technology significantly increases the blanket’s mechanical strength and prevents layer separation. Needled blankets have greater durability against vibration, impact, and tension. - Fiber Purity:
A high percentage of alumina (Al₂O₃) and silica (SiO₂) in ceramic fibers directly correlates with thermal resistance and longevity. Lower purity fibers become brittle more quickly. - Density:
Contrary to popular belief, “higher density” is not always better. Density should be chosen based on the application; high density provides better insulation but reduces flexibility, while lower density is more suitable for surfaces with complex shapes.
Question 3: What Other Destructive Factors is Your Refractory Blanket Resistant To?
Temperature isn’t the only enemy of refractory blankets!
The critical question is: “What kind of hazards does your work environment present?”
- Thermal Shock:
In processes with sudden temperature changes, the blanket must withstand rapid expansion and contraction without cracking. Flexible ceramic fibers are ideal for such conditions. - Mechanical Abrasion and Vibration:
Around fans, moving chambers, or high-traffic areas, the blanket must be resistant to wear and tear. - Chemicals, Oil, and Corrosive Vapors:
If there’s contact with acids, alkalis, or oil, blankets with a protective coating like Teflon or silicone should be used.
Question 4: What Are the Hidden Costs of Installing a Refractory Blanket?
The listed price is only part of the true cost.
Ask: “How much time, expertise, and auxiliary equipment does the installation of this blanket require?”
- Surface Preparation:
The surface must be clean and free of rust to ensure proper adhesion and performance. - Installation Accessories:
Refractory wire, pins, washers, and high-temperature adhesive are essential for a proper installation. - Installation Skill:
Improper installation can lead to cold spots, tears, and reduced insulation efficiency.

We are not just a product supplier. The Klevers Aryana engineering team provides design, supervision, and execution services for insulation systems to prevent energy loss and future hidden costs.
Question 5: What Role Does a Refractory Blanket Play in Energy Efficiency and the Environment?
A quality refractory blanket is not an expense; it’s a long-term investment.
The key question: “How much energy will this blanket save over its lifespan?”
- Low Thermal Conductivity:
The lower this value, the less energy is lost, and the higher the efficiency. - Thermal Stability:
A high-quality blanket retains its thickness and density even after repeated thermal cycles. - Environmental Compatibility:
Modern ceramic fibers, unlike old asbestos materials, are safe and comply with global health and safety standards.
Question 6: What Do the Standards and Product Warranty Tell You?
A product without a valid certificate is like an empty promise.
Ask: “Does this refractory blanket have independent test reports and a reliable warranty?”
- Certifications:
Look for documents that verify temperature tolerance, thermal conductivity, and mechanical strength. - Warranty:
Read the warranty terms carefully. Does it only cover manufacturing defects, or does it also guarantee performance at specific temperatures?
Question 7: Is Your Vendor a Technical Partner or Just a Supplier?
This is perhaps the most important question.
The difference between a successful purchase and a costly failure lies in this answer.
A true technical partner:
- Asks about the details of your process, operating temperatures, and challenges.
- Compares options technically and transparently.
- Provides samples and allows for testing.
- Offers technical support after the sale.
