Serious DIYers and craftspeople, this ceramic fiber insulation board is professional-grade material for your high-temperature projects! Measuring 1/2 inch thick by 19.7x39.4 inches, this board can withstand temperatures up to 2300°F - making it perfect for wood stoves, fireplaces, pizza ovens, forges, kilns, and furnaces. The high density (20-24 lb/ft³) provides excellent thermal insulation while maintaining good compressive strength. What's really handy is how easy it is to work with - you can cut it with a hacksaw blade or knife, drill it, or machine it to fit your specific application. The low organic content means it maintains its structural integrity even under extreme heat conditions. When you first heat it up, the binding agents burn off between 450-600°F (which might cause some slight odor and brown discoloration temporarily), but after that initial burn-in, it becomes pure white and odorless. The permanent linear shrinkage is minimal (3.5% max at 2200°F), so it maintains its dimensions well over time. Whether you're building a custom pizza oven, lining a forge, creating baffles for wood stoves, or need heat shielding for various applications, this ceramic board delivers professional performance. The quality is consistent, and it's much easier to work with than traditional refractory bricks while providing superior insulation properties.
