High Temperature Insulation Boards

PAR Group supply a comprehensive selection of high temperature insulation boards that are commonly used in thermal and electrical management applications. Our range of insulation boards is manufactured from materials such as calcium silicate, inorganic mineral fibre, Portland cement, mica and ceramic fibre, which are then combined with selected binders and fillers. These products are often used as kiln and furnace linings, die-cast mould insulation, or electrical insulation components (depending on the grade).

High-temperature insulation materials can be supplied as standard sheets, cut-to-size pieces, or machined into custom shapes through the utilisation of in-house CNC machining facilities. Quotations can be provided for bespoke enquires by sending us existing samples or drawings. For more specific information regarding individual grades, including availability and technical data, please click the ‘view product’ buttons below. Alternatively, if you're still unsure about the grade you require for your application, please contact our technical sales team who will be happy to assist you.

We also supply a range of asbestos-free, high-temperature insulation blankets and papers that are commonly used as refractory back-up insulation or manufactured into gaskets if required.
