How Much is Calcium Silicate Board? - Firebird

Calcium silicate board is a widely used high-performance insulation material designed for use in high-temperature industrial environments such as steel plants, cement kilns, power stations, and aluminum smelters. If you’re planning a project and wondering about the cost of this material, understanding the key factors that influence its price will help you make an informed decision.

1. Density: The Foundation of Cost

One of the most important factors affecting the price of calcium silicate boards is density, which typically ranges from 250 kg/m³ to 850 kg/m³. Lower-density boards (250–300 kg/m³) are lightweight, easier to handle, and ideal for applications where mechanical stress is minimal. These are the most cost-effective options.

Medium-density boards (400–500 kg/m³) strike a balance between insulation efficiency and mechanical strength. They are commonly used in furnace linings, ducts, and general industrial insulation.

High-density boards (up to 850 kg/m³) offer superior compressive strength and durability, making them ideal for load-bearing areas, machining into precise components, and areas with high thermal shock. These boards come at a premium due to their enhanced performance and material composition.

2. Size and Thickness: Volume Matters

Calcium silicate boards are typically priced by volume (per cubic meter), which means that board size and thickness directly influence the final cost. Standard dimensions include ×500 mm, × mm, and × mm. Thicknesses range from as little as 10 mm up to 100 mm or more.

Thinner boards are cheaper and easier to install, while thicker boards are more robust and provide higher thermal resistance. Customized sizes and shapes—such as machined parts or pipe covers—will also affect the price depending on the complexity of the design and processing required.

3. Temperature Rating: Higher Resistance, Higher Cost

Calcium silicate boards are engineered for different operating temperatures, typically categorized as:

• °C Boards – Suitable for general insulation in kilns, furnaces, and fireproof doors.
• °C Boards – Designed for more demanding applications such as steel ladles, aluminum spouts, and smelters.

Higher temperature resistance requires improved formulations and refined manufacturing techniques. As such, °C boards are generally more expensive than °C boards. For applications requiring high durability under thermal cycling, investing in higher-rated materials ensures long-term performance and lower replacement frequency.

4. Surface Treatment & Finishing Options

Surface condition and edge processing are often overlooked but can impact both performance and cost. At Firebird, we offer the following options:

• Standard Finish (Type A): Original dimpled surface, non-cut edges. Ideal for hidden insulation applications.
• Premium Finish (Type B): Four-side cutting and double-side sanding. This upgrade improves edge sealing, reduces dust, and enhances aesthetics—recommended for visible or precise applications.

Special surface treatments or custom cutting may result in additional charges but can improve installation efficiency and insulation performance.

5. Packaging and Logistics

Packaging style can also affect total cost. Firebird provides standard carton box packaging on wooden pallets for safe transportation and storage. For overseas orders, reinforced packaging or waterproof wrapping may be advised depending on shipping conditions.

Also, consider the destination port charges, customs clearance, and international freight costs when evaluating your total procurement budget.

6. Price Guidance (Without Exact Numbers)

While exact prices vary based on quantity, customization, and location, here’s a general guideline to help you estimate:

• Low-Density Boards (250–300 kg/m³): Most economical, ideal for budget-sensitive projects.
• Mid-Density Boards (400–500 kg/m³): Balanced cost and performance, suitable for general industry use.
• High-Density Boards (850 kg/m³): Premium pricing, used for high-stress and precision applications.

Additional services such as cutting, sanding, and premium packaging will be quoted separately depending on project needs.
