Self-supporting
Vacuum-formed boards — rigid and dimensionally stable without additional support structure.
Biosoluble
AES fibre — exonerated under Note Q of EU Regulation EC/1272/2008 (CLP), non-carcinogenic.
Machinable
Sawing, drilling, routing — precision cut-to-size and CNC-machined parts.
PRODUCT TYPE
Superwool® Boards are vacuum-formed, self-supporting insulation boards made from biosoluble alkaline earth silicate fibre (AES). Unlike flexible fibre blankets, boards are rigid and dimensionally stable — they require no additional support structure. The boards can be sawn, drilled and routed, making them suitable for precision cut-to-size parts and CNC-machined components. Superwool® Boards contain no binder in the base fibre and produce no fumes or odours on first firing.
MATERIAL
Alkaline earth silicate fibre (AES) consists of amorphous fibres produced by melting and rapid solidification of a combination of silicon dioxide (SiO₂) and calcium oxide (CaO) with magnesium oxide (MgO). AES fibres are biosoluble: they are exonerated from classification as carcinogenic under Note Q of EU Regulation EC/1272/2008 (CLP).
Morgan Advanced Materials
Morgan Thermal Ceramics has been developing low-biopersistence fibres for over 20 years, revolutionising the use of fibres for high-temperature insulation applications. The patented Superwool® products are manufactured using ISO 9002-certified processes and consist of alkaline earth silicate (AES) fibres specifically engineered for benefits in high-temperature insulation. The board programme comprises the Prime chemistry (1300 °C) and the Plus family (H, 85, LTI, HTC).

Superwool® Boards combine the proven insulation performance of Superwool® fibre chemistry with the mechanical strength of a vacuum-formed board. The boards are self-supporting, can be installed without additional support structures and are machinable — sawing, drilling, routing. Prime Boards offer the highest classification temperature (1300 °C) within the AES board range, while the Plus variants (H, 85, LTI, HTC) cover different property profiles for specific service conditions.
All Superwool® Board variants are purely inorganic — no binder in the base fibre. No fumes or odours on first firing. The AES fibre is biosoluble and not classified as carcinogenic (Note Q, EC/1272/2008 CLP).
Applications
- Furnace linings for industrial and chamber furnaces
- Kiln furniture
- Back-up insulation behind monolithic linings
- Fire protection barriers and firewall panels
- Appliance insulation (domestic and industrial)
- Expansion joints in tunnel kilns
- Boiler and exhaust insulation
Frequently Asked Questions (FAQ)
What are Superwool® Boards?
Superwool® Boards are vacuum-formed, self-supporting insulation boards made from biosoluble alkaline earth silicate fibre (AES) by Morgan Advanced Materials. Unlike flexible Superwool® blankets, boards are rigid and dimensionally stable. They are suited for applications where insulation must be mounted without additional support structure — e.g. furnace linings, kiln furniture or fire protection barriers.
What is the difference between Prime Board and Plus Board?
Prime Board is based on the latest Superwool® fibre chemistry and achieves a classification temperature of 1300 °C. The Plus family comprises four sub-variants (H, 85, LTI, HTC) with different property profiles — Board 85 and HTC are rated for service temperatures up to 1000 °C. The specific choice depends on temperature, mechanical load and installation conditions — contact us for a recommendation.
What applications are Superwool® Boards used for?
Typical applications include: furnace linings for industrial and chamber furnaces, kiln furniture, back-up insulation behind monolithic linings, fire protection barriers and firewall panels, appliance insulation for domestic and industrial equipment, expansion joints in tunnel kilns, boiler and exhaust insulation.
Can Superwool® Boards be machined?
Yes. All Superwool® Board variants can be sawn, drilled and routed. This enables precision cut-to-size parts and CNC-machined components. Dust extraction should be used when cutting — although AES fibres are biosoluble and exonerated from carcinogenic classification under Note Q EC/1272/2008.
Are Superwool® Boards biosoluble and safe to handle?
Yes. All Superwool® variants consist of alkaline earth silicate fibres (AES), which are exonerated from classification as carcinogenic under Note Q of EU Regulation EC/1272/2008 (CLP). The fibres are biosoluble — they are broken down in the body within a short time. Unlike traditional refractory ceramic fibres (RCF/ASW), Superwool® products do not fall under CMR Cat. 2 labelling requirements.
