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 και πλάκες πυριτικού ασβεστίου 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

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

✅ Calcium Silicate Board

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

II. Performance Comparison

Category	Πίνακας κεραμικών ινών	Πλάκα πυριτικού ασβεστίου
Αντοχή στη θερμοκρασία	Up to 1000–1430℃, excellent stability at high temperatures	Generally ≤1000℃
Δύναμη	Relatively lower, more brittle	High strength, good mechanical properties
Weight	Lighter, easier for installation	Heavier
Θερμομόνωση	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 Πίνακας κεραμικών ινών (e.g., furnace linings, high-temperature metallurgy).
For high strength or mechanical load-bearing requirements
→ Choose Πλάκα πυριτικού ασβεστίου (e.g., fireproof partitions, construction, power equipment).
For lightweight thermal insulation requirements
→ Choose Πίνακας κεραμικών ινών (ideal for high-temperature insulation layers).
For moisture resistance, fireproofing, and structural support
→ Choose Πλάκα πυριτικού ασβεστίου (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.
