PYROCERAM®

Pyroceram® is transparent glass-ceramic having almost a zero thermal expansion. It is an excellent choice for applications when there is the probability of high heat and cold shock. Pyroceram® is widely used for Residential applications such as fireplace and wood burning stove windows, oven windows, broiler windows and other such appliances.  Pyroceram® is also used in architectural and outdoor lighting, electronics, UV lightwave blocking applications and chemical process sight glass.

Pyroceram is available in sheet sizes:
790mm x 590mm x 3.0 ± .20mm | 1580mm x 800mm x 5.0 ± .20mm
