Robax® is the ideal fire viewing glass. It is a clear ceramic glass with great resistance to thermal shock and heat, so much that it can withstand up to 760° C for up to 5 hours and 560° C for up to 5,000 hours.

The main application for Robax® is the use in electric, oil or gas stoves as well as wood, coal, pellet fireplaces and room heaters. With the appropriate test approvals, Robax® can also be used as viewing panels in fire doors where more than 120 minutes of Integrity Fire Resistance Level (FRL) performance against flames, smoke and hot gasses is required.
