To mitigate the health and environmental risks posed by traditional asbestos-containing materials, and in response to tightening safety regulations and the growing need for high-performance, eco-friendly insulation, the building and industrial sectors have driven forward the development of asbestos-free calcium silicate board. Through ongoing process refinement and material engineering, this thermal insulation product has evolved to reliably endure continuous operating temperatures between 650°C and 1100°C.
Designed as a safe, non-asbestos substitute for conventional insulation, calcium silicate board delivers stable performance across a continuous service temperature range of 650°C to 1100°C. Advances in material processing have endowed the board with a favorable combination of low weight, low thermal conductivity, high mechanical strength, ease of installation, long-term dependability, and outstanding durability. Offered in three standard grades—650°C, 1000°C, and 1100°C—it is well-suited for applications such as backup insulation for furnaces in the steel, petrochemical, ceramic, cement, and glass industries, as well as for fireproofing in building construction.

Primary Applications
Steel structure fire protection: Covering steel beams and columns, delaying the temperature rise during a fire and preventing collapse.
Back insulation for industrial furnaces and kilns: Applied between the furnace wall and the furnace shell to reduce heat loss and achieve energy conservation.
External wall external insulation system: As an A-level non-combustible insulation board, it enhances building energy efficiency and fire safety.
Interior fireproof partition/ceiling: Used for firewalls and fireproof ceilings, meeting the requirements of fire protection zones.
Tunnel and Cable Fire Protection: Used as fire barriers for tunnel side walls or cable trenches to prevent the spread of flames.
High-temperature pipeline insulation: Covering hot air pipes, steam pipes, etc., to reduce heat loss and prevent burns.
Frequently Asked Questions (FAQ)
Q1: How do I select the right insulation grade for my furnace?
A: Selection depends on the maximum operating temperature, thermal cycling frequency, and chemical atmosphere. Please provide your design specifications for a tailored recommendation.
Q2: Do these materials contain hazardous substances?
A: We offer a range of bio-soluble (low-bio-persistence) fibers that meet international health and safety standards for handling and usage.
Q3: Can you provide customized shapes?
A: Yes, we provide vacuum-formed custom shapes, blocks, and modules based on your CAD drawings to ensure a perfect fit for your equipment.
