Glass Bodyguard for Sparky’s Heroes
The world’s first transparent glass-ceramic has now been produced with the microfloat process. Pyran® Platinum holds all the trump cards for use in the North American fire protection market.
Firefighters are the undisputed heroes in the U.S. This can be seen not only in countless action films, but also be traced back through history. Fire protection traditionally plays an important role in America. For instance, the standards for materials used in fire protection require that special glasses pass extremely rigorous tests. In the case of a fire, they must not only offer protection from smoke, fire and hot gases for a specified minimum amount of time, but also ensure that they do not break suddenly and cause injury as a result of the shock caused by the cold water from a fire hose. The so-called hose stream test is conducted to ensure this.

Today, Pyran® Platinum fire-rated glass-ceramics are available in monolithic, as well as filmed and laminated forms for sophisticated fire protection and safety glazing applications. This portfolio enables the product to meet the code requirements for various fire-rated applications. Installed in windows, it offers up to 90 minutes of protection from smoke, fire and hot gases in accordance with the UL (Underwriters Laboratories) classification, and in doors, as long as 180 minutes. The glass-ceramic also stands up to the thermal shock of the hose stream test. This test calls for the glass-ceramic to be heated up to as high as 1000 degree Celsius inside a large furnace and then, depending on its classification, be subjected to stress and the defined pressure of a standard water jet.
Distributors say these new qualities also set standards in the North American architecture market (see also interview). Jordan Richards, President of Glassopolis, a newly formed subsidiary of ProScience, is convinced: ”Pyran® Platinum is without doubt the best choice among glass-ceramics for fire protection.” ProScience, a large, well-known supplier of technical flat glass from Toronto, Canada, provides the North American architecture market with special-purpose glasses through Glassopolis. Pyran® Platinum is expected to drive the business forward mainly because new building regulations open up new market opportunities. For instance, safety regulations in most states now prohibit conventional wired glass from being used in the U.S. market for fire protective and safety glass, where impact resistance is required.
