Vermiculite board used as register heat shields for wood burners 
Density:500-1000KG/M3 Adjustable 
Size: 2440x1220x(20-60)mm

Heat resistant Vermiculite board for Stove fire bricks and registration plates, fireproof fireplace surrounds. Wood burning Stoves. Easy to cut , does not expand. Vermiculite is cheaper and more efficient than fire bricks.

Highly insulating refractory panels made from vermiculite containing no ceramic fibres

Vermiculite boards are easily to cut and shape to any size fire bricks with woodworking tools; as shown in picture on right. A multitude of design possibilities
High temperature resistance, low heat accumulation in lining materials, good thermal shock resistance
High mechanical strength
Good insulation capacity providing better combustion in wood burning stoves and cleaner waste gas.
No ceramic fibres, non-dusting surfaces , non-irritant, odourless

Fire Resistant vermiculite board offer excellent thermal insulation properties and minimal shrinkage at high temperatures. These products find application where fire protection is needed such as in replacement Fire Bricks, panels and bespoke applications where fire resistance or low electrical conductivity is required.
The Vermiculite boards are available in a number of different sizes

Increase the efficiency of your Wood burning Stove

A good idea which increases efficiency of your Wood burning Stove is to replace the grate or cover it with a piece of vermiculite board and allow a good layer of ash to form on the base of the stove.

This reduces the primary air flow and slows down the rate at which the wood burns.

What is Vermiculite

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. It 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) it is light and clean to handle, has a high insulation value, acoustic-insulating properties and will absorb and hold a wide range of liquids.


These granules are non-combustible, and are insoluble in water and all organic solvents. The expanded mineral is easily poured, is light, clean, highly absorbent and provides baffle against impact shock when used for packaging.


Exfoliated vermiculite is used in the friction brake linings market, high temperature insulation, loft insulation, various construction products, animal feeds, horticulture and many other industrial applications. With its layered structure and surface characteristics is utilised in products such as intumescent coatings and gaskets, the treatment of toxic waste and air-freight packaging of hazardous goods.
