Important Note
This panel is pyro-ceramic glass — it is not tempered glass. Tempered glass is only suitable to ~450°F and must not be used in wood or coal stoves. Pyro-ceramic withstands up to 1,400°F (760°C), making it ideal for high-efficiency heating appliances.
Why Choose Our Ceramic Stove Glass?
Unlike tempered glass options that are unsafe at stove temperatures, our OEM-grade pyro-ceramic glass offers superior heat tolerance with minimal thermal expansion. Restore the safety, clarity, and performance of your Harman stove with a precision-cut panel built for long-term reliability.
