Thermal Ceramics V-19 Block Insulation
Categories: Ceramic

Material Notes: V-19 Block is manufactured from vermiculite granules and high-temperature bonding materials. This versatile product is available in thicknesses up to 4".

V-19 Block is an economical, energy saving insulation with minimal shrinkage at its top temperature limit, and good compressive strength. These features make V-19 a good design choice for back-up insulation applications.

V-19 compositional characteristics permits effective adhesion of cement finishes. Therm-O-Stix is an ideal adhesive product with superior qualities when used with V-19.

V-19 Block must be pre-drilled for placement since it is not impalable over anchors due to its high green strength. However this property makes it easy to cast or gun against with refractory castables.


  • Economical structural insulation
  • 1900°F (1038°C) temperature rating
  • Low thermal conductivity
  • No organic binders or fillers
  • Manufactured to close dimensional tolerances, max. ± 1/16”
  • Volumetric stable to use limit
  • Alternative to mineral wool board
  • Applications:

  • Back-up insulation in all industries
  • Suitable for use with castables, firebrick, refractory plastic and ceramic fiber
