The Correct Glass For My Heating Application

CERAMIC GLASS

Wood stoves, fireplace inserts, coal stoves, and gas fireplaces must have ceramic glass on their doors due to the fact that they produce constant temperatures that exceed 500 degrees F. In addition, the flame is usually less than 6 inches from the glass in these types of heating applications. 

Therefore, tempered replacement glass cannot be installed in wood stoves, fireplace inserts, or gas fireplaces.

TEMPERED GLASS

Wood burning fireplaces are approved to receive tempered glass doors. Due to its high mechanical strength and thermal shock rating, tempered glass is a safe choice for this type of heating application. In addition, fireplace doors are usually a safe distance from the flames (more than 6 inches away).
