For all you DIY enthusiasts building stoves, pizza ovens, forges, or kilns, this ceramic fiber board is an absolute essential! These boards are rated for temperatures up to 2300°F, making them perfect for high-heat applications where regular insulation just won't cut it. Each pack contains two 20x20x1 inch boards with a density of 20-24 lbs/ft³, providing excellent thermal insulation with low heat storage and great resistance to thermal shock. What's really handy is how easy they are to work with - you can cut them with a simple knife or hacksaw blade, and they can be drilled and machined to fit your specific project. Perfect for wood stoves, fireplaces, pizza ovens, kilns, forges, pellet stoves, furnace linings, boiler insulation, heat shields, and combustion chambers. Just a heads up - when you first heat them up, the organic binder burns off between 450-600°F, which might cause some slight odor and discoloration (they'll turn brownish then pure white). This is completely normal and once the binder burns out, they're odorless and ready for long-term use. The compressive strength is impressive at 78 PSI at 25% deformation, and they have minimal linear shrinkage even after 24 hours at 2200°F. Whether you're a professional or a serious DIYer, this quality insulation board will help your project retain heat efficiently and safely. Your stove or oven will work better and more efficiently with proper insulation like this!
