About Calcium Silicate Boards

Calcium Silicate Boards

CMS Industries is a leading manufacturer, supplier and exporter of heavy duty and highly finished Plain Calcium Silicate Board which is used in the industrial and constructional applications to provide insulation around the extreme temperature pipes due to its excellent fire endurance properties that makes it capable to resist harsh heating waves. It is most commonly used in various industrial facilities such as chemical plants, refineries, and steam electric power plants. Buy from us this heat resistant block in various different customizable sizes.

Superior Fire Protection and Thermal Insulation

Designed to meet stringent fire safety standards, Calcium Silicate Boards deliver outstanding fire resistance. Tested to IS 976:1963 Class 1 & 2 specifications, these non-combustible boards tolerate continuous exposure up to 1000C. Their high thermal stability and low thermal conductivity (0.035-0.11 W/mK) ensure reliable insulation, keeping premises safe and efficient even in high-temperature environments.

Structural Reliability and Dimensional Accuracy

Calcium Silicate Boards maintain excellent dimensional stability under temperature fluctuations, thanks to their engineered porosity and density (approximately 1000 g/cm3). Square or tapered edges enhance installation versatility, while the smooth surface and sturdy construction give both aesthetic appeal and practical resilience. Available in various thicknesses and sizes, they deliver superior structural support in diverse environments.

Multifunctional Applications Across Industries

With a combination of fire protection, acoustic insulation (up to 35 dB), and moisture resistance, Calcium Silicate Boards are a go-to solution for wall partitions, ceilings, duct covering, and specialized insulation. They are widely utilized in construction, marine, petrochemical, and industrial settings for exporter, manufacturer, and supplier needs across India.

FAQ's of Calcium Silicate Boards:

Q: How are Calcium Silicate Boards typically installed in construction projects?

A: Calcium Silicate Boards can be cut and fixed using screws or mechanical fasteners to metal or wooden framing systems. Square or tapered edges facilitate easy joint flushness and finishing. Proper joint treatment and priming are recommended for applications like wall partitions and false ceilings.

Q: What benefits do Calcium Silicate Boards offer for fireproofing and high-temperature insulation?

A: Owing to their non-combustibility, conforming to IS 976:1963 Class 1 & 2, and a service temperature up to 1000C, Calcium Silicate Boards provide outstanding fire protection. Their low thermal conductivity and high dimensional stability further ensure dependable insulation in environments facing extreme heat.

Q: When should Calcium Silicate Boards be chosen over other insulation materials?

A: These boards are ideal whenever fire safety, thermal insulation, and acoustic control are critical-especially in areas requiring frequent exposure to high temperatures and stringent fireproofing, such as duct coverings, marine insulation, or industrial partitions.

Q: Where are Calcium Silicate Boards most commonly used?

A: Calcium Silicate Boards see extensive usage in commercial and industrial construction, marine vessels, petrochemical plants, and areas requiring sound insulation. They are indispensable for wall partitions, ceilings, and duct insulation, particularly where fire resistance is mandatory.

Q: What is the process for maintaining Calcium Silicate Boards over time?

A: Routine inspection for mechanical damage and moisture ingress is recommended. Due to their low moisture content ( 10%) and high hardness, these boards require minimal regular maintenance-typically limited to cleaning and prompt repair of any damaged sections.

Q: What usage advantages do Calcium Silicate Boards have in terms of health and environment?

A: With a neutral to alkaline pH (7-10), high purity (above 90%), and being asbestos-free, Calcium Silicate Boards are safe for indoor environments. Their durable, non-toxic composition supports healthy air quality and complies with environmental safety standards.
