Everything You Need to Know About Replacing Your Stove Glass

If the glass on your wood stove or fireplace insert is cracked, cloudy, or damaged, it’s time for a replacement. Beyond looks, your stove glass plays a major role in safety and performance. Here’s everything you need to know about choosing, installing, and maintaining the right glass for your unit — straight from the experts at Total Hearth.

1. Choose the Right Type of Glass

Not all stove glass is the same. Using the wrong kind can be dangerous and lead to costly damage.

• Ceramic glass is the standard for wood stoves, pellet stoves, and high-efficiency fireplaces. It can handle extreme heat — up to 1400°F — and is slightly tinted amber.

• Tempered glass is best for low-heat, decorative fireplaces. It’s heat-resistant up to around 450°F but will shatter if used in a high-temperature stove.
  When in doubt, always choose ceramic glass. It’s designed for the high temperatures your stove produces and ensures long-term durability and safety.

2. Measure Accurately Before Ordering

Proper measurements ensure a perfect fit. If you’re replacing an existing piece, measure the old glass. If it’s missing, measure the door opening and subtract about 1/8 inch from each side for heat expansion. Most stove glass is 3/16 inch thick.
Total Hearth offers custom-cut glass made to your exact specifications — so you get a perfect fit, every time.

3. Replace Carefully and Safely

Before starting, make sure the stove is completely cool.

1. Remove the stove door (if possible) and lay it flat on a protected surface.

2. Remove the retaining clips or screws and take out the damaged glass.

3. Clean off old gasket material or debris.

4. Install a new gasket if needed to create a proper seal.

5. Set the new glass into place with gentle pressure — never force it.

6. Tighten clips evenly, but don’t overtighten. Ceramic glass needs slight room to expand under heat.

4. Why Replacing Stove Glass Matters

Replacing damaged or old glass isn’t just cosmetic. The right glass:

• Improves efficiency by maintaining proper airflow and combustion.

• Enhances safety by preventing sparks, embers, or gases from escaping.

• Extends appliance life, reducing stress on internal components.

• Restores a clear view of your fire — one of the best parts of owning a wood stove.

5. Maintenance Tips for Longer Glass Life

• Clean only when cool using a soft cloth and non-abrasive cleaner.

• Avoid harsh chemicals or tools like steel wool that can scratch the surface.

• Use seasoned, dry wood to reduce soot and creosote buildup.

• Inspect gaskets regularly — a worn seal can cause overheating and stress the glass.

• Check for chips or cracks during your seasonal maintenance; replace promptly if you find damage.
