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