Should I choose tempered or neoceramic glass for my fireplace doors?

Tempered glass is simply glass that has been heated in a furnace and then quickly cooled. This process increases the strength of the glass and the ability of the glass to withstand the high temperatures associated with a fireplace. The average thermal shock rating (the temperature at which the structural integrity of the glass will fail and shatter) is between 400 - 600 degrees Fahrenheit. This is usually sufficient for most wood and gas fireplaces.  If you choose tempered glass, be sure to keep the fire at least 6" away from the glass. 

If you live in a cold region where you burn your fire hot you probably want to upgrade to neoceramic glass.

Neoceramic glass can tolerate continuous temperatures up to 1292 Degrees Fahrenheit- nearly 3 times the heat resistance of tempered glass.  This far exceeds any fire you would want in your fireplace.  Neoceramic glass does not have the structural integrity of tempered glass, so for aluminum doors tempered glass is recommended whereas with Ironhaus steel doors, neoceram glass is a good match.
