Vermiculite V4 Coarse

Vermiculite V4 is normally supplied in plastic sacks containing 100 litres (approximately 3.5ft3).


  • Loft insulation
  • Packaging
  • Loose-pour aggregate
  • Backfill for firebacks and boilers
  • Firebase embers
  • High temperature insulation
  • Wicking agent
  • Chimney lining

It can be used to pour back down the chimney filling the void between the brick chinmey and the flexible flue liner.

This will improve the performance of your stove by ensuring the flue gases stay warm enough to escape quickly therefore ensuring the draw of the chimney stays strong.
It also massively reduces condesation of the flue gases.
