Promalight 320

Promalight Calcium Silicate Board

Promalight 320 and 320HD are a nanoporous insulation material for the most demanding thermal insulation applications where the largest temperature drop is required through the thinnest possible cross section with lowest possible mass.

  • Thermal conductivity starting at 0.023W/mK
  • Best performing product in its class
  • Available in a range of finishes (Plain, PE shrink wrapped, foil-faced, mica-faced)
  • Machinable (HD grade for improved machining definition)

 Advantages and properties

  • Improved thermal performance reduces cross sectional thickness
  • Lightweight thin panels
  • Low thermal capacity reducing heat soak
  • Easily machinable
  • Chemically inert
  • Thermally resistant to 950°C
