Differences and Selection Guide Between Ceramic Fiber Board and Calcium Silicate Board - Your Thermal insulation material Manufactruer

In the field of industrial and building insulation materials, ceramic fiber boards and kalsiyum silikat levhalar are among the most commonly used products. Both offer good fire resistance and thermal insulation performance, but their characteristics, application scenarios, and selection principles differ. Choosing the right material can significantly improve safety and cost-effectiveness in projects.

I. Basic Differences Between Ceramic Fiber Board and Calcium Silicate Board

✅ Ceramic Fiber Board

Malzeme: Made from ceramic fiber cotton through vacuum forming
Sıcaklık Dayanımı: 1000–1260℃, up to 1430℃ for premium grades
Features: Lightweight, excellent thermal insulation, low thermal conductivity
Uygulamalar: High-temperature industrial furnace linings, power plant boilers, metallurgy, high-temperature insulation layers

✅ Calcium Silicate Board

Malzeme: Produced from siliceous and calcareous materials under autoclave curing
Sıcaklık Dayanımı: 650–1000℃ (depending on grade)
Features: High strength, good compressive resistance, excellent moisture resistance
Uygulamalar: Fireproof partition walls, external wall insulation, power equipment insulation, pipeline insulation

II. Performance Comparison

Category	Seramik Elyaf Levha	Kalsiyum Silikat Levha
Sıcaklık Dayanımı	Up to 1000–1430℃, excellent stability at high temperatures	Generally ≤1000℃
Güç	Relatively lower, more brittle	High strength, good mechanical properties
Weight	Lighter, easier for installation	Heavier
Isı Yalıtımı	Very low thermal conductivity, superior insulation	Good insulation, slightly lower than ceramic fiber board
Main Applications	Metallurgy, glass, ceramics, power plant boilers	Construction, power, shipbuilding, chemical pipelines

III. Selection Guide

For applications above 1000℃
→ Choose Seramik Elyaf Levha (e.g., furnace linings, high-temperature metallurgy).
For high strength or mechanical load-bearing requirements
→ Choose Kalsiyum Silikat Levha (e.g., fireproof partitions, construction, power equipment).
For lightweight thermal insulation requirements
→ Choose Seramik Elyaf Levha (ideal for high-temperature insulation layers).
For moisture resistance, fireproofing, and structural support
→ Choose Kalsiyum Silikat Levha (commonly used in construction and power industries).

IV. Conclusion

Ceramic Fiber Board → High-temperature insulation, lightweight refractory solution
Calcium Silicate Board → High strength, fireproof partitions, and pipeline insulation

In practical projects, these two materials are often used together: for example, ceramic fiber boards for furnace linings (insulation), and calcium silicate boards for outer structural support, achieving the best combined performance.
