Vermiculite Board

Why choose vermiculite board

The Stove Wizard Vermiculite Boards are a high-performance, heat-resistant insulation solution for wood-burning stoves, multi-fuel stoves, fireplaces, pizza ovens, grills and other high-temperature applications.

Made from premium high-density vermiculite, they are lightweight yet durable, with strong thermal insulation and heat reflection to help improve efficiency and protect surrounding surfaces. Rated to withstand temperatures up to 1200°C, they are ideal for replacing worn stove liners, constructing fire chambers, insulating pizza ovens and creating custom heat shields.

• High-density premium vermiculite construction
• Temperature resistant up to 1200°C
• Non-toxic and asbestos-free
• Available in a range of sizes and thicknesses

Heat resistance & insulation

Engineered for demanding heat-intensive environments, vermiculite boards offer excellent insulation while maintaining structural integrity under prolonged high temperatures. Their low thermal conductivity helps reduce heat loss, retain heat within the appliance and improve overall energy efficiency.

The natural insulating and reflective properties of vermiculite help direct heat back into the combustion chamber, promoting higher internal temperatures and more efficient burning.

• Improved combustion performance
• Better heat output
• Reduced fuel consumption
• Cleaner, more efficient burns
• Reduced soot and residue build-up

Easy to cut & fit

Unlike traditional firebricks and dense refractory materials, vermiculite boards are lightweight and simple to cut, shape and install using standard hand tools.

That makes them ideal for custom projects, replacement stove panels and made-to-measure applications where precise fitting is required. Despite their lightweight construction, they still provide excellent durability and long-lasting performance when used correctly in high-temperature environments.

• Lightweight and easy to install
• Simple to cut, shape and customise
• Suitable for domestic and commercial applications

Suitable uses

The Stove Wizard Vermiculite Boards are suitable for a wide range of high-temperature applications, including:

• Wood-burning stoves
• Multi-fuel stoves
• Fireplaces
• Pizza ovens
• Grills and other high-temperature applications

Boards are commonly used on the sides, rear and top sections of pizza ovens, grills and heating appliances. They are not intended for use as a cooking surface or direct food preparation area. Vermiculite is not waterproof and should always be kept dry during storage and installation.

For safe, cost-effective delivery, larger board sizes are supplied in sections: a 1000mm × 610mm × 25mm board as 2 × 500mm × 610mm × 25mm boards, and a 2000mm × 610mm × 25mm board as 4 × 500mm × 610mm × 25mm boards. Sections can be fitted side-by-side during installation.
