Q: What Kind Of Glass Do I Need?
Most North American fireplaces and wood stoves have either tempered glass or high temperature glass-ceramic. Tempered glass is most often found on low temperature and economy fireplaces, while glass-ceramic is found on higher end fireplaces and most wood stoves. The difference between them is that tempered glass is less expensive, but it's not suitable for many applications.
The problem with tempered glass is that it cannot survive high heat. It will break when heated above a few hundred degrees. Also, tempered will shatter if its suddenly cooled (spill a drink on it, or drop some snow on it while loading your stove). Another shortcoming of tempered is that at modest temperatures the glass will 'lose its temper' over time meaning that its safety aspects will decline as you use your fireplace.
Glass-ceramics, on the other hand, are made especially for high heat applications like fireplaces and wood stoves. Its the same type of material that is used on stoves and glass cooktops. It can take the heat (up to 1400F) and will not break if the temperature changes rapidly.
You can tell what kind of glass you had in your fireplace or wood stove by looking at the broken pieces of your previous glass. Tempered glass breaks into uniform sized little pebbles about 1/2" long (like a broken car window). Glass-ceramics break like regular annealed glass in longer random sized shards (like a broken house window).
Most of the time, glass-ceramic is what you need. It is meant for this application and it can be cut to your exact size quickly. Most of the fireplace and wood stove replacement glass we supply is glass-ceramic. We offer SCHOTT ROBAX glass-ceramic. Its by far the worldwide market leader in glass-ceramics for heating appliances. It has the quality and durability you'd expect from the market leading product. It's exactly what the manufacturers use. You cannot go wrong using it. For these reasons, we no longer offer tempered glass will quote you SCHOTT ROBAX glass-ceramic.
For special applications like EPA certified low emission wood stoves you can request a special version of the glass called ROBAX IR, which has an additional special optical coating on it that reflects infra-red heat back into the firebox to help the stove burn hotter and help combust the fuel more completely and cleanly.

Q: Do I Need A New Gasket?
Most glass is mounted with clips or tabs that hold the glass in place. Usually there is a gasket between the glass and the metal frame of the fireplace or wood stove door.
This gasket is important and must be functional and installed correctly. It often is a fiberglass rope or tape that serves to seal the air gap between the glass and the metal frame. The gasket provides an airtight seal, important to keep the smoke out of the room, yet it is slightly flexible enough to allow the glass and metal frame to thermally expand or contract at slightly different rates when heated while maintaining a tight air seal.
OEM gaskets come in many shapes - we can supply you with a standard gasket rope which often can do the job - or you can check with your local fireplace dealer for a specific replacement gasket.
Q: What Size Do I Need?
Replacement glass is only available in flat glass. Curved or bent glass is not available for replacement.
Measure the existing glass or opening with enough clearance for the gasket. You don't want the glass to fit too tightly as it can be cracked by the frame if its too tight. If the glass is rectangular, measure the width and the height. If the glass is curved or shaped send us the measurements or a tracing as best you can. For complicated shapes some people will cut a piece of cardboard to fit the opening, then measure or send us that.
