High temperature fibre free thermal insulation material - Thermcell

Developed through patented technology, ThermCell stands out because it brings together a number of properties which give you the edge at a technical and human level.

Fibre free and lightweight, up to 1700°C

ThermCell is fibre free heat insulation material which functions well at high temperatures and has a low density. 

The material’s unique porous structure gives it excellent thermal shock resistance over a wide temperature range, up to 1700°C / 3092°F. This translates into faster firing cycles, which will deliver higher yields and energy savings.

The fact that ThermCell is fibre free also guarantees consistent product quality in the extreme heat of the glass industry.

A safer, more productive work space

ThermCell is simple and safe to handle. It can be easily machined into complex shapes. There is no need for water cooling or bespoke diamond tools and the dust produced is similar to that of a floor tile or brick. 

The fibre free status removes any concerns about skin irritation or respiratory problems and does not require specialist protective clothing.

Whatever you need, we can help

ThermCell is produced in four different grades. Your team can choose the grade that matches what they need, whether it’s thermal heat insulation, alumina content, thermal shock resistance or density. Often it is a finely balanced decision, and we can help you weigh up what’s best for your applications.

ThermCell can be used in a wide range of applications, including:

  • High temperature furnaces
  • Fast firing of metal parts
  • Electrical heating modules
  • Kiln furniture
  • Microwave industrial furnaces
  • Low thermal mass kiln car/hanging roof
  • Dental furnaces.

ThermCell is available in rigid standard boards, 450mm x 300mm, with four thickness options. We can also produce bricks and customised shapes on request. Contact us today and we can explore your project in more detail and send you a full technical data sheet. We look forward to speaking to you.
