Fireplace Glass Replacement

Need fireplace glass replacement but not sure which type of glass is safe for your fireplace, insert, or stove? The most important step is choosing the correct material. Some fireplaces use tempered glass, while high-heat wood stoves, pellet stoves, coal stoves, and many inserts require ceramic glass.

This guide will help you choose the right replacement fireplace glass and point you to the correct ordering option.

Which Fireplace Glass Replacement Do You Need?

Fireplace glass replacement usually falls into two main categories: tempered glass and ceramic glass. The right choice depends on your appliance type, heat level, and whether the glass is exposed to direct flame.

Use Ceramic Glass For High-Heat Applications

Choose custom cut ceramic glass if you are replacing glass in a wood stove, pellet stove, coal stove, fireplace insert, or any high-heat appliance where the glass may be exposed to direct flame or extreme temperatures.

Ceramic glass, including materials commonly known as Pyroceram, NeoCeram, or Robax, is designed for high temperatures and thermal shock resistance. It can withstand much higher heat than tempered glass and is the safe choice for many stove and insert applications.

Use Tempered Glass For Fireplace Doors and Screens

Choose custom tempered glass cut to size for fireplace doors, bi-fold fireplace doors, fireplace screens, and approved lower-heat applications where the glass is not exposed to direct flame.

Tempered fireplace glass is stronger than regular glass and is designed to break into small pieces rather than large sharp shards. However, it should not be used in airtight wood stoves, pellet stoves, coal stoves, or high-efficiency inserts.

How to Measure for Fireplace Glass Replacement

Accurate measurements are key to getting a safe and proper fit for your replacement fireplace glass.

1. Let the appliance cool completely before removing or measuring glass.
2. Remove the old glass if possible and clean the frame or opening.
3. Measure the opening where the glass will sit, not just the old glass, since old glass may have shifted or warped.
4. Measure width and height to the nearest 1/16 inch.
5. Subtract at least 1/8 inch from both height and width to allow for expansion and fit.
6. Double-check your measurements before ordering because custom glass is non-returnable unless made incorrectly.

Common Fireplace Glass Replacement Options

Fireplace Door Glass Replacement

Many masonry fireplace doors and bi-fold fireplace doors use tempered glass panels. If your glass sits several inches away from the flame and your manufacturer specifies tempered glass, choose custom tempered glass cut to size.

Fireplace Insert Glass Replacement

Many fireplace inserts operate at higher temperatures and require ceramic glass. If the glass is exposed to high heat or direct flame, choose custom cut ceramic glass.

Wood Stove and Pellet Stove Glass Replacement

Wood stoves, pellet stoves, and coal stoves should use ceramic glass, not tempered glass. Tempered glass can fail under the heat produced by these appliances.
