About Microtherm

  • Microtherm is the leading manufacturer of high performance thermal insulation. Why is Microtherm® the best thermal insulation available?
  • Microtherm® thermal insulation effectively minimises the transmission of heat over a large temperature range (from cryogenic temperatures to 1200 °C / 2192 °F).
  • With a porous structure based on clumps of amorphous silica particles sized around 5 – 25 nm in dia, Microtherm® is classified as a microporous insulation.
  • Microtherm® has appreciably better thermal performance at high temperatures than other more conventional insulation products. Microtherm® performs even better than still air.
  • Why is Microtherm® such good value for money?
  • Microtherm® the versatile insulation
