Replacement Glass For Heat Stoves
We are the best source for custom replacement glass for fireplaces! Based in the United States, our delivery is super fast! Replacement wood stove glass is generally cut and sent out for shipping the same day it is ordered. If ordered later in the evening, we usually get it cut and out the door the next day. Pattern cuts for wood stoves may add 1 day or more depending on if we need a template, or the complexity of your request. Fireplace door glass takes a bit longer than wood stove glass. This is because of the tempering process, which can take a few extra days. We temper each piece and inspect for quality on a per order basis, so the extra wait is well worth it. For both wood stove and fireplace glass, shipping to your door generally takes 2 to 3 days.
High Temperature Ceramic Glass
High temperature Pyroceram ceramic glass is suitable for use in gas, oil, wood, pellet, coal burning, and bio-stoves. Its 1380° F thermal shock rating makes it ideal for any application where high temperature tolerance is required. There is no visual or performance difference between Pyroceram, Neoceram, or Robax -- those names are just trademarks. We use only genuine Pyroceram ceramic glass. Available in 3/16" thickness only.
Intended For These Stove Types:
NOTE: Our glass is not for use on cook-tops or range-tops.
What is Pyroceram ceramic wood stove glass?
Pyroceram is a special kind of glass-ceramic material that was accidentally derived by Corning Glass experiments in the 1950's. In 1953 a scientist was working on a new photosensitive glass called Fotoform which contained silver nanoparticles to embetter the structure of the glass. Upon heating up a fragment of this glass he noticed that it resisted breakage at very high temperatures. Upon further investigation, it was clear that Corning had stumbled onto something great. By adding quartz to further strengthen the ceramic glass, they were able to create the roots of Pyroceram. This early quartz ceramic was known as Fotoceram and it would take 6 more years of development before it evolved into what we now know as Pyroceram ceramic glass. For over 50 years Pyroceram has been the go-to glass for repairing or replacing the glass in wood stove doors.
Why does my wood stove need replacement Pyroceram ceramic glass?
Generally, wood stoves, along with pellet, coal, bio, or oil, operate at very high temperatures and require a special kind of replacement glass. These temperatures can exceed 1000° F, requiring glass to be manufactured using the high temperature Pyroceram crystalline formula specially designed for stove doors in order to withstand the heat. Normal or tempered glass, simply cannot withstand the high heat and will shatter when your wood stove door comes up to operating temperature. Pyroceram ceramic wood stove glass has a maximum heat range of 1380° F making it an ideal solution for most types of stoves requiring the highest heat tolerances.
How do I replace the Pyroceram glass and fiberglass gasket in my wood stove door?
Although the details differ for each type of wood stove door, the overall process is generally the same. First, let your stove and door completely cool down so you don't get burned. Next, try to remove the old wood stove glass without breaking it. If this old glass is already broken, you can use tape over the cracks to prevent it from falling apart when removed. Once the old wood stove glass is removed, measure it as accurately as possible. Take a few measurements to make sure it is accurate. Next, remove any old stove gasket, cement, and sealant material. Take note of how much new stove gasket you need. If there was no old stove glass at all, now is the time to measure the channel that new replacement glass would fit into. Measure 1/8" less from each side to compensate for gasket material and thermal expansion occurring when glass heats up. You do not want your replacement wood stove glass to fit too tight! Once your new glass and gasket arrives, reverse the process. Put cement and stove gasket in first, followed by the Pyroceram glass, then secure it with your wood stove door hardware. After the cement cures for the recommended time, you are ready to use your wood stove!
Do I need a new fiberglass gasket for my Pyroceram wood stove glass install?
Yes, you also need to replace the gasket in your wood stove in 99% of glass replacement cases. This is because old fiberglass stove gasket is often covered in hard cement, is crusty, or fraying. It's not safe or efficient to run your wood stove at operating temperature using old gasket. If there are any gaps or big frays, it could allow dangerous carbon monoxide to escape around the replacement glass and out of the wood stove door into your living space. Too much fresh air could get in, resulting in a less-than-controllable wood stove burn or spikes in radiated heat. Finally, a damaged stove gasket may also be less obviously effecting the operation of your stove gasification re-burner, door air wash system, or depending on the severity of old gasket condition, even change the way the wood stove vents from the chimney, causing unnecessary creosote buildup in your system. Please always install new fiberglass gasket when replacing Pyroceram glass in your wood stove. We have a selection of fiberglass gaskets that should fit any wood stove door.
Can you cut Pyroceram glass to match the special shape of my wood stove door?
Absolutely! We have over 30 custom shapes available for our wood stove glass, but that's not where we stop. Give us a call or chat, and we can explore the full potential of what patterns we can create. We may require you to trace a template of the old wood stove glass and mail it to us so we can get it exactly right. We can cut just about any pattern including custom arches, rounded corners, or even perfect circles. Unfortunately, these patterns only apply to our replacement Pyroceram wood stove glass and cannot be applied to tempered style fireplace glass.
Can I use high strength tempered instead of high temperature Pyroceram glass in my stove?
Tempered glass has a lower temperature rating of 400° F meaning that it will shatter after a couple minutes in the extreme temperatures of your wood stove door or other type of stove application. If broken and left unattended, this is dangerous and could release smoke, carbon monoxide, or sparks into your home. Always use the recommended high temperature Pyroceram ceramic for your replacement wood stove glass needs.
Will Pyroceram ceramic glass work in my kitchen cook top or range?
Certain formulas of Pyroceram are intended as wood stove replacements, and other formulas are manufacturer specific, and intended only for kitchen appliances. We specialize in replacement wood stove glass to ensure you get the best service and quality and therefore do not recommend using our glass for cook stove tops, ranges, or oven doors. It may void warranty or even worse, cause injury if it breaks due to the wrong thickness or lack of manufacturer specific glass formula details. Only use our Pyroceram ceramic glass in a wood, coal, pellet, or bio stove door.
Other Heat Resistant Glass
There are generally 4 types of heat resistant glass, used for a variety of heating and hearth applications:
- Tempax glass: flawless appearance, holds up to 580° F before breaking into sharp shards.
- Ceramic glass: will withstand to 1380° F with optional IR coating before shattering into sharp pieces
- Mica: mineral strip that is easy to cut and resists extreme heat up to 1800° F before burning through.
Each type of high temperature glass is different, with specific recommended applications. It is important to make sure your specifications are correct and you allow room for the glass to expand with the heat.
