Vermiculite Board: The Ideal Lining Solution for Fireplaces & Wood Stoves

A great fireplace relies not only on design, but also on reliable fire-resistant insulation inside the firebox.

Standard straight panels work for simple builds, while many custom fireplaces, slim stoves and replacement projects demand curved liners, baffle plates, back panels, base plates and special cut-out parts.

Our vermiculite boards are widely used for fireplace firebox lining, stove baffles and replacement refractory panels.

✅ A1 non-combustible, withstands up to 1100°C

✅ Low thermal conductivity — reflects heat back into the chamber for cleaner, more efficient combustion, and protects the metal shell from overheating & warping

✅ Inorganic mineral material, releases NO toxic fumes under high heat, safe for residential use

✅ CNC machinable: curved, grooved, drilled, notched or one-piece custom profiles available

✅ Good thermal shock resistance, low high-temperature shrinkage, long service life

✅ Thickness & density adjustable to match your fireplace design

We support full custom fabrication from your drawings or samples. Whether you need a single replacement baffle or a complete set of shaped fireplace liners, we deliver one-stop refractory insulation solutions.
