How to Choose the Right Replacement Glass for Your Fireplace or Stove

Fireplaces and wood stoves add charm and warmth to any home or business, but when the glass gets cracked, stained, or cloudy, it’s time to replace it. Choosing the right replacement glass isn’t just about aesthetics—it’s about safety, performance, and longevity. Whether you're a homeowner or a professional contractor, here’s what you need to know to make the best choice.

🔥 Why Replacement Glass Matters

Fireplace glass is not like regular window glass. It must withstand extreme heat, thermal shock, and frequent temperature fluctuations without breaking. Using the wrong type of glass can result in dangerous breakage, poor heating efficiency, or smoke leaks.

Types of High-Temperature Glass

When shopping for fireplace replacement glass, you'll encounter a few common options—each with specific properties.

1. Ceramic Glass

• Withstands up to 1,400°F

• Ideal for wood-burning stoves and fireplaces

• Comes in brand names like Pyroceram and Neoceram

• Resists thermal shock and discoloration

Ceramic glass is your go-to if you have a wood stove or high-efficiency fireplace. It’s strong and can handle real heat without warping.

2. Tempered Glass

• Rated for up to ~500°F

• Suitable for gas fireplaces with sealed glass panels

• Cannot be used in wood stoves or high-temperature applications

Tempered glass is a cost-effective option for gas fireplace parts where extreme heat isn't an issue.

📏 How to Measure for Replacement Glass

Getting the right fit is critical for safety and performance. Here's how to measure:

1. Remove the existing glass if it's safe to do so.

2. Measure the width and height to the nearest 1/16 inch.

3. If you’re ordering custom fireplace glass, provide exact dimensions—don’t round up!

4. Account for gasket thickness if applicable.

If you're unsure what type of glass your unit requires, check your stove or fireplace manual or contact our team for expert help.
