Calcium Silicate Insulation Board (650°C)

The calcium silicate insulation board is a specialized product derived from hydrated calcium silicate, designed specifically for high-temperature insulation applications in industrial environments. Its manufacturing process emphasizes precision and quality, resulting in a product that stands in contrast to generic alternatives. This insulation board is available in standard thicknesses of 25mm and 50mm, which enhances its capability to manage light structural loads. Such attributes make it particularly suitable for cladding around ducts and walls that require both strength and thermal efficiency.

In terms of composition, the board features a structural matrix of hydrated calcium silicate that imparts both resilience and lightweight characteristics. This unique formulation ensures it performs effectively under thermal stress, providing resistance to degradation amid harsh conditions. Its chemical stability further enhances its overall durability, enabling consistent performance over time, thus making it applicable for continuous use in demanding operational setups.

Engineered to withstand temperatures reaching 650°C, the insulation board is ideal for environments where high heat is prevalent, such as in cement production and steam piping frameworks. With a density of 200 kg/m³ and a thermal conductivity of 0.060 W/m·K, this board effectively minimizes heat loss during operations, contributing to improved energy efficiency. Such performance characteristics lead to enhanced operational efficiency of industrial machinery and processes, representing a valuable asset in reducing energy costs.

Supplied in sheets measuring 610 x 1220mm and packed in practical batches of 12 with shrink-wrap for transport protection, it allows for straightforward logistics. Buyers are encouraged to determine the appropriate thickness and quantity respective to their projects before placing an order. This insulation board is readily available in Nairobi and can be efficiently shipped across East Africa, ensuring prompt delivery to support diverse industrial needs.

This board is manufactured from hydrated calcium silicate rather than the higher-alumina mix used in Zenco's 1000°C-rated calcium silicate board, giving it a lower service temperature but a more cost-effective fit for mid-range heat applications. It is specified across a wide set of duties: boiler insulation, furnace lining, HVAC duct insulation, steam-pipe insulation, hot-equipment protection, fire-resistant barriers, thermal barriers in kilns, wall insulation in power plants, heat-exchanger insulation, refractory backup insulation, piping cladding, industrial oven linings, generator insulation, and chimney insulation systems — a range that spans power generation, cement manufacturing, petrochemical processing, ceramics manufacturing, and food processing. Buyers also know this product line by its common names — insulating board, hydrated calcium silicate board, or high-temperature insulation board — which reflect the same underlying material. Standard sizes are 610 x 1220mm sheets in 25mm or 50mm thickness, shrink-wrapped or carton-packed in batches of 12 boards, with custom pack sizes available on request for larger relining projects. Because its compressive strength is rated at ≥1.0 MPa against the thicker board's ≥1.5 MPa, it's the better fit for cladding, duct, and wall applications rather than load-bearing floor or platform insulation — check the surface temperature and any foot-traffic requirement before choosing between the two calcium silicate boards in our range. Installation is straightforward: cut to fit with a sharp utility knife and secure using adhesive or mechanical fasteners, following the same ASTM C612 handling practice used across our calcium silicate line; a snug fit at panel joints matters more than exact centring, since gaps at joints are the most common source of heat leak on this type of board. We supply this board to industrial buyers across Kenya and East Africa and can advise on thickness selection for your specific furnace, boiler, or piping layout, including guidance on where the standard 25mm or heavier 50mm option makes more sense.
