Technical Composite : Sizal® Board
Rigid Insulation SIZAL®BOARD
Our SIZAL®BOARD and SIZAL®CELL range is a complete line of thermal insulators that open the way to many industrial or laboratory applications up to 1,800 °C. The mechanical and thermal performance of SIZAL® products guarantee substantial savings in terms of energy and costs.
SIZAL®BOARD is a range of rigid high-temperature insulation composed of polycrystalline alumina wool (PCW) fibres. It offers an alternative to aluminium silicate fibre-based materials. These are referred to as Refractory Ceramic Fibres (RCF).
Thanks to its structure, this product has excellent resistance to ruptures and/or cracking during rapid temperature rises. SIZAL®BOARD offers not only a very homogeneous structure, but also has virtually no non-fibrous particles (shots) during its manufacture. This means is it safe to use and compliant with occupational health and safety.
All SIZAL®BOARD products can be delivered pre-calcined. Cooking parts at more than 350 °C eliminates all traces of organic binders that may be present in the materials. This operation avoids gas emissions and potential pollution during more sensitive applications.
Applications of SIZAL®BOARD Composite
- Insulation panels for industrial or laboratory installations
- Furnace linings (electric and gas)
- Furnace, burner or turbine components.
- Mechanical parts, part supports, and more.

SIZAL® is a high-end insulation solution for the thermal management of your industrial installations or laboratories.
Our machining centres are equipped with suction systems, specific cutting tools, and fastening systems for more fragile parts in order to guarantee the best possible quality. SIZAL® products have good machinability thanks to their homogeneous structure. However, the minimum tolerance values are ±0.5 mm because of the porosities size.
Furnace linings and components
The quality of SIZAL® products is compatible with the construction and renovation of gas and electric furnaces. The use of this material permits greater compactness, with a resulting improvement in efficiency and energy saving.
Mechanical strength tests executed in electric furnaces of various designs, under both reducing and oxidizing atmospheres, have confirmed the exceptional resistance of SIZAL®BOARD, particularly in response to high-amplitude hot and cold cycles, from 100 to 800 °C in less than an hour.
