The Stove Wizard Vermiculite Boards

Premium Heat-Resistant Insulation for Stoves, Fireplaces, Ovens & More

When it comes to thermal protection and energy efficiency in high-temperature environments, The Stove Wizard Vermiculite Boards set the standard. Manufactured from high-density, fire-resistant vermiculite, these boards offer a combination of exceptional insulation, durability, and versatility, making them the perfect solution for lining wood-burning stoves, constructing firebacks, building pizza ovens, and creating custom heat shields.

Capable of withstanding temperatures up to 1100°C , these boards help retain and reflect heat where it matters most — inside your appliance or cooking area — reducing heat loss, improving combustion, and increasing fuel efficiency.


🔥 Superior Thermal Performance

The Stove Wizard Vermiculite Boards are designed for intense heat exposure. They maintain structural integrity under prolonged high temperatures and are ideal for direct flame environments such as stove chambers, kilns, and oven interiors. Their low thermal conductivity means less energy is lost through surrounding materials, making them an energy-saving solution for heating systems.


♨️ Enhanced Heat Reflection & Efficiency

Thanks to vermiculite’s natural insulating and reflective properties, these boards actively bounce radiant heat back into the firebox, raising internal temperatures and improving combustion quality. This results in cleaner burns, reduced soot buildup, and more consistent heat output — especially useful in stoves, fireplaces, and pizza ovens.


🛠️ Lightweight, Durable & Customizable

Unlike dense clay or ceramic firebricks, vermiculite boards are lightweight and easy to work with. They can be easily cut, shaped, or drilled using basic hand tools, allowing for precise installation in both new builds and retrofit projects. Despite their light weight, they’re remarkably durable, impact-resistant, and long-lasting, even with regular exposure to open flame and thermal cycling.


🧱 Versatile Applications

Whether you’re a professional installer, stove manufacturer, or a DIY enthusiast, The Stove Wizard Vermiculite Boards are ideal for a wide variety of heat-resistant applications:

  • Stove and fireplace linings

  • Back panels and baffles

  • Wood-fired and pizza oven insulation

  • Thermal barriers and firebacks

  • Wall-mounted heat shields or hearth panels

  • Workshop kilns and forges

HOW TO APPLY

If ever unsure how to apply, please contact a gas safe engineer

If you are looking for replacement gas fire coals or other ceramics such as pebbles or logs, then we would recommend taking a picture of how your coals are set out so you can position them correctly count how many there are so you can order the correct amount and matching the size as close as possible as the ones being replaced. This will ensure a similar flame visual effect on the gas fire.

All our products are suitable for gas, outside gas fire pits, electric and bio ethanol fires.

TIME TO CHANGE YOUR GAS FIRE ACCESSORIES?

We recommend that you should change your gas fire coals, logs pebbles at least once every 2 years or as they become discoloured and worn. Gas fire manufacturers will normally insist that you use their specific brand of coals. Despite this, thousands of homes every year use non-standard ceramics on their gas fires without any issues.
