Home heating and cooking projects need reliable, heat-resistant materials, especially for ovens and hearth repairs, which is why The Stove Wizard Firebrick Fire Board exists. Confidence during DIY builds comes from durable, high-temperature components that perform under repeated use. Is this compact slab the right fit for small ovens and fireplace tweaks?
⚡ At a Glance
- • Heat Resistance: High-density vermiculite construction resists temperatures up to 1250 degrees and supports continuous heating
- • Best for: Lining cooking chambers in wood-fired ovens, creating fireplaces, fire boxes and improving small wood heaters
- • Not ideal for: Large-scale structural masonry or applications needing full-size bricks and load-bearing strength
A 200mm x 200mm x 25mm high-density vermiculite slab rated to 1250 degrees. Smooth, porous surface offers low thermal conductivity and good heat retention.
High-temperature protection - with high-density vermiculite construction
High-density vermiculite composition tolerates sustained temperatures up to 1250 degrees without combustion, permitting continuous heating in confined chambers. The material's structure resists breakdown under repeated thermal cycles.
Safe lining for small oven chambers, fireboxes and wood heaters, extending surrounding material lifespan and reducing risk of heat damage.
Improved heat retention - thanks to low thermal conductivity
Low thermal conductivity slows heat transfer through the slab while the porous surface traps and stores thermal energy. Heat disperses slowly, creating a steady internal temperature in cooking or warming spaces.
More even baking and longer-lasting warmth with less fuel, useful for keeping food warm or achieving stable cooking temperatures.
Versatile practical size - with a 200 x 200 x 25mm slab
Compact 200mm x 200mm dimensions and roughly 25mm thickness make the slab easy to place, cut or trim for customised fits. The smooth, porous finish doubles as a working surface for small food items.
Handy for DIY oven builds, use as a food-warming plate or rustic pizza base, and effective for trimming to improve fireplace seals.

🏆 Our Verdict
Suitable for DIYers and small-scale builders who need compact, heatproof panels for cooking chambers or fireplace repairs. High-density vermiculite with a smooth, porous surface tolerates up to 1250 degrees while improving heat retention and efficiency. While a single slab represents a small, purposeful investment, durability and multiple uses make it a practical long-term addition to ovens and hearth projects.
