Calcium Silicate Board (1000°C)

Calcium silicate board is a rigid insulation material formulated specifically for high-temperature applications. Comprising silica, lime, and reinforcing fibers, it exhibits superior structural integrity and thermal stability compared to other generic insulation options. The rigorous manufacturing process ensures that each board maintains precise dimensions and consistency, catering to environments where reliability is paramount. This board is fundamentally designed to offer robust support where traditional insulation may falter under extreme conditions, making it a critical choice for industrial settings involving high thermal exposure.

The composition of calcium silicate board provides exceptional mechanical strength and durability. The silica content and reinforcing fibers work in synergy to create a lightweight material that can withstand the rigors of intense heat and repeated thermal cycling. This blend permits the board to maintain its shape and performance in demanding operational environments, ensuring that thermal management systems operate effectively without risk of material failure. The inherent properties of this board facilitate optimal insulation, minimizing heat transfer and enhancing energy efficiency in thermal applications, thus contributing to operational cost savings.

In service, this insulation board can endure temperatures reaching up to 1000°C, which makes it particularly suitable for high-stress applications within boilers and furnaces. With a density of 160 kg/m³, its lightweight structure alleviates concerns about heavy loading on supporting elements. Additionally, the board exhibits a low thermal conductivity that significantly reduces energy loss, enhancing overall system performance. A compressive strength of ≥1.5 MPa allows the board to support light foot traffic and cladding without risk of degradation, making it an excellent choice for various industrial installations.

Zenco supplies calcium silicate boards in standardized sheets measuring 610 x 1220mm, with a consistent thickness of 25mm. Each board is palletized and shrink-wrapped to protect against damage during transport and storage. Clients must confirm the required dimensions, thickness, and quantity when placing orders to ensure they receive the appropriate material for their application. In Nairobi and throughout East Africa, our efficient logistics guarantee timely delivery of these essential products to support critical industrial operations.

Calcium silicate board is a rigid insulation board formed from silica, lime, and reinforcing fibres, engineered to hold its shape and load-bearing capacity at temperatures up to 1000°C. Industrial buyers specify it across a broad range of duties: boiler insulation, furnace backing, kiln car lining, piping insulation in process plants, high-temperature duct insulation, radiant heating system insulation, industrial equipment backing, heat shielding in manufacturing, laboratory equipment insulation, protective lining for storage tanks, and even fireproofing and soundproofing in industrial buildings — anywhere a board rather than a flexible blanket is needed to carry mechanical loads or support cladding. Cement, steel, petrochemical, and power-generation plants make up the core buyer base, alongside construction, food processing, and glass-manufacturing sites that use it for wall insulation and equipment backing. Some buyers know this product by its common trade names — CalSil board, silica board, or calcium silicate insulation — which describe the same silica-lime-fibre composition. It ships as 610 x 1220mm boards in 25mm thickness, stacked on wooden pallets and shrink-wrapped, with custom crate sizes available for bulk orders. Selection should be driven by the ≥1.5 MPa compressive strength rating alongside the 0.065 W/m·K thermal conductivity figure — both matter where the board will bear the weight of cladding, ductwork fixings, or foot traffic during maintenance, not just resist heat. Installation is straightforward: cut boards to size and secure with standard fasteners, following the ASTM C612 handling guidance that governs this product class — a clean, square cut matters more than most installers expect, since a ragged edge concentrates stress and can crack the board under thermal movement. Buyers across Kenya and East Africa order it for both new-build furnace linings and shutdown-period refractory repairs, where board dimensions need to match existing cut patterns exactly, and where fast turnaround on repeat orders matters during planned maintenance windows.
