Fireplace Glass Replacement

Most gas fireplaces are enclosed with tempered glass, which can tolerate temperatures up to 400-500 degrees Fahrenheit. These are often fireplaces where the doors are a safe distance from the flames.

Generally the safe distance from the front of the grate to the fireplace glass is 4 inches or greater to maintain a maximum of 400-500 F.

Use Ceramic Glass. Ceramic Glass comes as either Pyroceram or Neoceram. This can withstand temperatures up to Up to 1472 F. for short durations or 1292 F. on a continuous basis.

Glass thicknesses are shown as a Nominal Thickness, meaning “in name only”, used solely for identification. These are commonly listed as 1/8″, 5/32″, 1/8″, 3/16″, 1/4″ for fireplace glass applications. The nominal size may not match the exact thickness but will be within the acceptable industry-wide thickness range and can correspond to a large number of highly standardized dimensions and tolerances.

We sell glass for many different applications including fireplaces, woodstoves, gas & pellet stoves, table tops, shelving, entertainment units, kitchen cabinets & backsplashes, light fixtures, halogen lamps, machine gauges, ovens, laboratory tools, etc. These are just some of the many applications our glass has been used in. Since all of our projects are custom cut to order if you have a unique project you are working on, submit an inquiry or give us a call and we’ll see what we can do to help.

Don’t worry! We can cut to almost any shape. In many cases, we can follow a written description that you have added on our contact form in the comments section. If there are special changes or hard-to-describe dimensions, feel free to submit a preliminary drawing for approval by email to support@onedayglass.com or by fax to (360) 892-8152. Of course, for best results we may recommend that you provide a paper template; there is no substitute for an exact pattern. Please make a tracing of your glass on a large piece of butcher paper/cardboard/grocery sack/etc. and mail it to us at:

Please include your name and contact information on or with the pattern and one of our customer service reps will contact you once the pattern is received to confirm your order.

Tempered glass is regular glass that has been heat treated to increase strength and thermal shock resistance to prevent injury by changing the break pattern. Tempered glass is used in applications where heat, mechanical strength and safety are a factor.

For example, the glass on motor vehicles is tempered to make it strong and less dangerous when it shatters or breaks. Tempered glass is also used in fireplace doors, on masonry and prefabricated fireplaces equipped with a grate to hold the burning wood.

Tempered glass can withstand constant temperatures of 470 deg F. If tempered glass is exposed to higher temperatures, it gradually weakens the structure of the glass thus making it more susceptible to breakage. If a piece of tempered glass is exposed to continuous temperatures of 600 deg F or more, the glass will shatter into small pieces.

Ceramic Glass commonly referred to as glass but it is actually a transparent ceramic. Unlike true glass, Ceramics can withstands continuous exposure to high temperatures without fear of destruction. It is also resistant to failure due to temperature variation. It is the ideal solution for many wood stoves and fireplaces where glass panels are less than 6 inches from the flames. We carry two different types of ceramic glass. Ceramic glass can withstand continuous temperatures of 1292 deg F or 1472 deg F for limited times.

There is nothing special about Neoceram^® or Pyroceram^® that will prevent it from becoming stained by heat or buildup inside your woodstove or fireplace. If you are having problems with the glass staining, you should consult with a local stove or fireplace shop to discuss possible culprits such as the type of wood that is burned or whether or if the woodstove or fireplace requires cleaning or other maintenance.

The NeoCeram and PyroCeram that we provide is as good as quality as you would buy from your typical glass shop. Why are our prices so low? The difference is we buy and stock large quantities and can sell it to you cheaper.

A “seamed” edge is one that has been lightly sanded to remove any sharp burrs. Glass with a seamed edge is safe to handle but is not decorative. It is our standard finish and is available at no extra charge. We will never send out glass with sharp edges that you could not handle safely without being cut.

The seamed edge is recommended for all applications in which the edges of the glass are not exposed.

For example, if your glass will be installed into the frame of a fireplace door and no one will see the edges once the glass has been installed, a seamed edge is all you need.

For shelves, table tops, or the like, you may want to consider upgrading to a more finished/decorate edge.

The types of glass listed are the only types of glass that we keep in stock and that are available to ship right away. If you have a specific type of glass you need for a project (i.e. special tints, thickness, or patterns), please contact our office. We may be able to special order glass to meet your needs. Please keep in mind that special orders may take up to 2 weeks to be completed and that prices will vary depending on your requests.
