How to Choose the Right Ceramic Fiber Board for Your Furnace Application

Selecting the right ceramic fiber board for your furnace application can be challenging, especially with multiple temperature grades, densities, and thicknesses available. Here's a practical guide to help you make the right choice.

Step 1: Determine Your Operating Temperature

The most important factor in ceramic fiber board selection is temperature. Choose a classification temperature at least one grade higher than your furnace's maximum continuous operating temperature.

Step 2: Consider Your Furnace Type

Different furnace types place different demands on ceramic fiber boards:

• Heat treatment furnaces: Need low heat storage and fast thermal response — choose lower density boards (200–240 kg/m³)
• Induction furnaces: Need high thermal shock resistance — choose 1400°C–1600°C grade with medium density
• Glass furnaces: Need contamination-free insulation — choose high-purity boards with no soluble alkali metals
• Laboratory furnaces: Need custom sizes and high precision — custom fabrication available with no minimum order

Step 3: Choose the Right Thickness

Board thickness depends on furnace temperature and size:

• 25–50mm: For smaller furnaces, laboratory furnaces, and secondary insulation layers
• 50–100mm: For standard industrial furnace linings and heat treatment furnaces
• 100–150mm: For high-temperature furnaces (1600°C+) and large industrial kilns

Step 4: Consider Customization

If your furnace requires non-standard dimensions, custom fabrication is available. We offer ceramic fiber boards in any size, with no minimum order quantity, and dimensional accuracy down to ±1mm.

At FOVO Thermal, we help customers select the right ceramic fiber board for their specific furnace application.
