Vermiculite Fireproof Board

Vermiculite is the geological name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance. Rock and other impurities are removed from the crude ore which is then crushed and sorted into sizes. Vermiculite is a safe inert material, light in colour. When heated it expands (exfoliates) up to 30 times its original volume. The exfoliation process converts the dense flakes of ore into lightweight porous granules containing innumerable minute air layers. Exfoliated (expanded) vermiculite is light and clean to handle, has a high insulation value, acoustic-insulating properties and will absorb and hold a wide range of liquids.

Increase the efficiency of your Stove when Burning Wood

A good idea which increases efficiency of your Wood Burning Stove is to replace the grate or cover it with a fire brick of vermiculite and allow a good layer of ash to form on the base of the reduces the primary air flow and slows down the rate at which the wood burns.
