Overview: SIZAL® BOARD Composite
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. 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.
Pre-calcination
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.

Insulation panels
SIZAL® is a high-end insulation solution for the thermal management of your industrial installations or laboratories.
Customised Parts
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.

FAQs that can help you in this category
Calcium silicate boards have a low density (200–1,000 kg/m³), low thermal conductivity (~ 0.05–0.35 W/m·K) and high temperature resistance of up to 1,000°C. They are used as structural insulators.
Mica boards (phlogopite or muscovite) have great dielectric strength (>20 kV/mm) and temperature resistance up to 500–1,000°C, depending on the type. It must be permanently compressed between 2 other boards to preserve its mechanical integrity (the silicon binder degrades at high temperature). Use of mica composite requires particular attention: please contact Final Advanced Materials for more information.
Yes, the inorganic composites produced by Final Advanced Materials can be CNC machined. Machining of calcium silicate-based (CaSiO₃) refractories or derived materials of the insulating boards type involves specific aspects relating to their low density, high porosity and low mechanical cohesion. Although these composites are not hard, they pose a high risk of scaling and crumbling: loads must therefore be minimised, and stripping of material must be avoided. The resulting powder is very abrasive and it is therefore essential that a dust extraction system is installed on your machinery. We can machine these materials in our production shop.
For continuous use at 1,000°C, Final Advanced Materials recommends composites made of ceramic fibres or calcium silicate. These materials have a low thermal conductivity (~0.08–0.35 W/m·K) and high dimensional stability. Nanoporous composites can go as low as 0.02–0.04 W/m·K but are more mechanically fragile. The choice depends on your requirements: thermal insulation or mechanical resistance. We require a complete description of the application and of the stresses before we can recommend the most suitable product.
Final Advanced Materials' high-temperature composite panels have resistances ranging from 1 to 40 MPa when compressed, depending on the density.
Light insulating materials (fibres and microporous materials) are limited (~1–5 MPa), while denser composites (reinforced silicate, zirconia) can resist up to 10–20 MPa and even as high as 40 MPa in the case of a calcium silicate with a density of 1,300 kg/m3.
Specifically: all inorganic composites which are capable of withstanding exposure to high temperatures (>300°C) have no elasticity and are therefore quite fragile.
