PYRAN® Platinum

At a glance

PYRAN® Platinum is the best fire-rated glass you've ever seen

With PYRAN® Platinum, SCHOTT has succeeded in developing a revolutionary and innovative solution in the area of fire rated architectural glass. PYRAN® Platinum combines aesthetics and safety. Thanks to a unique manufacturing process it is able to provide high optical quality with outstanding clarity and mirror-smooth finish, without any trace of haze or amber tint.

PYRAN® Platinum is environmentally friendly – it is the world’s first transparent, floated fire rated glass ceramic which is produced without the environmentally harmful toxic metals arsenic and antimony. In the international glass industry, SCHOTT has been a pioneer in environmental and climate protection for many years. SCHOTT strives to meet the highest standards for sustainable environmental and climate protection, meeting or exceeding legal requirements.

Manufacturing Energy & Water Conservation


PYRAN® Platinum glass-ceramic is produced at SCHOTT Technical Glass Solutions, GmbH (SCHOTT TGS) in Jena, Germany. SCHOTT TGS cares for the environment as is demonstrated in the manufacture and distribution of PYRAN® Platinum fire-rated glass-ceramic. Highlights of our commitment to the environment concerning energy and water are as follows:

1. Energy

Renewable Energy
  • SCHOTT TGS purchases approximately 20% renewable electricity, sourced from wind, biomass, hydroelectric, solar and biogas.
  • SCHOTT TGS operates solar panels onsite, which feed the electric grid, and SCHOTT continues to develop photovoltaic technology.
  • Between the energy generated on site and the renewable electric energy purchased, 5.77% of PYRAN® Platinum’s energy is renewable.
Energy Conservation
  • The composition and production methods used to manufacture PYRAN® Platinum glass-ceramic are optimized to prevent energy-intensive post-processing. For example, the micro-float process used to form the glass results in a smooth texture-free surface that does not require polishing.
  • SCHOTT TGS employees practice energy conservation daily, for example by turning off lights and electric devices when not in use.
  • Self-audits of manufacturing areas at SCHOTT TGS are done every three months to identify areas for improvement, including energy and water conservation opportunities
2. Water

Water Balance
  • Water usage at the production facility is monitored.
  • Water and waste water streams are characterized. SCHOTT TGS meets or exceeds all applicable water usage and discharge laws.
Water Conservation
  • SCHOTT TGS in Jena has a special permit allowing the manufacturing site to pump gray water from the nearby river. Graywater is used instead of freshwater when feasible. Graywater represents more than 90% of the water used in manufacturing, including social/sanitation water in the manufacturing and office buildings of support staff for PYRAN® Platinum glass-ceramic
  • All of the process water used in the manufacturing process is recycled. Only evaporated losses are replaced. Recirculation loops are used at the cooling tower, cullet cooling, melt tank, and glass washing.
  • All of the buildings on site use low-flow toilets and fixtures. Tankless (on-demand) water heaters are installed in office kitchen areas. Automatic dishwashers run only when full.
  • Landscaping at SCHOTT’s facility in Jena does not include lawns or gardens requiring supplemental watering. Indoor houseplants with minimal water needs are used instead.
  • All of the waste water from the facility is discharged to the local wastewater treatment plant. This plant produces biogas.
 

Material Toxicity & Recyclabilty

PYRAN® Platinum glass-ceramic is produced at SCHOTT Technical Glass Solutions GmbH (SCHOTT TGS) in Jena, Germany. SCHOTT TGS cares for the environment in manufacturing and distributing PYRAN® Platinum. Highlights of our commitment to the environment regarding materials, recyclability and social responsibility are as follows:
Raw Materials
  • All incoming raw materials must meet strict tolerances for contamination
  • The handling and processing of raw materials in the batch house are engineered such that worker exposure is extremely limited
  • PYRAN® Platinum glass-ceramic is manufactured without hazardous heavy metals antimony or arsenic, which are normally used as refining agents. We are not contributing to the mining, transportation and continued demand of these toxic heavy metals.
Recyclability
  • In our PYRAN® Platinum glass-ceramic production facility, SCHOTT TGS in Jena, Germany, we currently recycle all of our internal cut-off and scrap material as cullet in our glass melts. The melt tank uses 40 to 50% cullet.
  • SCHOTT is committed to the conservation of natural resources and to reducing the amount of glass waste in landfills. Recycling glass-ceramic is not as simple as recycling consumer glass products due to the high heat input required for remelting. Therefore no public programs exist for local recycling of glass-ceramic in the United States. To minimize the amount of glass-ceramic in landfills in North America, SCHOTT launched a recycling program in summer 2010 to take back drops and unused material from our North American warehouse and from all PYRAN® glass-ceramic fabricators in North America to be re-used as cullet in the manufacturing process.
  • PYRAN® Platinum is permanently labeled and recyclable at the end of the product life.

Areas of application

Fire Door Lites

  • A Fire Door is the door component of a fire door assembly, that together with the frame, hardware and other accessories provide a specific degree of fire protection to the opening. Fire Doors are tested according to NFPA 252 or UL 10B or UL 10C and installed according to NFPA 80.
  • PYRAN® Platinum fire-rated glazing installed as vision panels in Fire Doors provides a clear view for occupants exiting the building in an emergency.
  • For Fire Door Lites installed in areas subject to human impact, PYRAN® Platinum F and PYRAN® Platinum L meet CPSC 16 CFR 1201 impact requirements.
  • PYRAN® Platinum in Fire Door Lites passes the required hose stream test and is fire-rated up to 180 minutes. It is permanently labeled D-H-90 or D-H-180.

Fire Window Glazing

  • Fire Windows are constructed and glazed to give protection against the passage of fire. Fire Windows are tested according to NFPA 257 or UL 9 and installed according to NFPA 80.
  • PYRAN® Platinum fire-rated glazing installed in Fire Windows remains clear during a fire and provides a clear view for occupants exiting the building in an emergency.

  • PYRAN® Platinum in Fire Windows passes the required hose stream test and is fire-rated up to 90 minutes. It is permanently labeled OH-90.

Transoms, Sidelites and Borrowed Lites

  • Transoms and Sidelites are smaller glazed windows that may surround the Fire Door. Borrowed Lites are installed in interior walls to allow light from an adjacent room. Transoms, Sidelites and Borrowed Lites in Fire Rated walls are constructed and glazed to give protection against the passage of fire. These three special windows are tested as Fire Windows according to NFPA 257 or UL 9 and installed according to NFPA 80.
  • PYRAN® Platinum fire-rated glazing installed in Fire Windows remains clear during a fire and provides a clear view for occupants exiting the building in an emergency.
