Vermiculite is a naturally occurring mineral formed into a pressed piece of board and then cut into shapes. Vermiculite fire bricks are non-combustible. A fire resistant product which is light and easy to cut with a wood saw.

Vermiculite fire bricks have excellent thermal insulation properties and have minimal shrinkage at high temperatures. These fire bricks are Fire Resistant and therefore they are ideal products to use in your wood burning or multi-fuel stove, providing fire protection exactly where it is needed.

Why do we need Vermiculite fire bricks ?

They are fitted to your wood-burning or multi-fuel stove for insulation purposes, allowing your stove to burn efficiently but also acting as a heat barrier and preventing the flames from reaching the steel stove walls causing damage to the stove itself.

Tips to make your fire bricks last longer
  • Do not use oversized logs in your stove which may cause damage
  • Do not overfill your stove
  • Ensure you only burn seasoned wood
  • Where possible, place the logs into the stove rather than throwing or dropping them.
  • If cleaning your stove internally do not use water or water based cleaning agents, vermiculite will weaken if it absorbs moisture
  • Avoid over-firing your stove.  The fire bricks will have at pink colour if this is occuring.
