Time to Replace Cracked Woodstove Glass

It’s time to prepare your woodstove for winter. That means inspecting, cleaning and replacing broken or cracked parts on your woodstove. Cracked woodstove glass is usually caused by mechanical damage such as closing the door on a log or getting hit during the off season.

Woodstove glass is actually not glass at all, but is a clear ceramic material that doesn’t expand or shrink with heat and cold. It has the ability to tolerate constant temperatures up to 1292 degrees Fahrenheit that tempered glass could not withstand. Woodstove glass is sold under brand names such as Pyroceram Glass®, NeoCeram Glass® or Robax Glass®. Comparison chart of the common woodstove glass brands.
