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.
Measuring For Replacement Woodstove Glass
Replacement ceramic glass for your woodstove can be cut to almost any shape. Simple shapes are easily measured with a tape measure. Complex shapes may require a tracing to prepare a paper pattern on a large piece of butcher paper or grocery sack. It is usually easiest to measure or trace from your current piece of woodstove glass.
Measurements should be within 1/16” and you want to be as precise as possible.
Thickness: How thick is the piece of glass that you need? Most woodstove glass is 3/16” thick (Neoceram). Ceramic glass also is available in 1/8” and 5/32” thicknesses.
Woodstove Winterizing Checklist
- Inspect the gasket and door. Replace damaged or cracked parts.
- Check the chimney for birds nest or other obstructions.
- Have a professional chimney sweep inspect and clean the flue prior to the first winter use. This will clean out the creosote buildup and help prevent your flue from catching fire.
- Inspect the damper to make sure it opens and closes smoothly.
- Inspect and replace any deteriorated bricks lining the firebox.
- Inspect the mortar joints on chimney and repair any cracked areas.
- Remove flammable items from around the stove.
