Vetrotech’s original PYROSWISS® now certified for 45-minute use

Pyroswiss 45 launch
Vetrotech Saint-Gobain, the company that pioneered PYROSWISS®, the world’s first highly tempered clear fire-resistant safety glass, is pleased to announce that the product trusted by architects and glaziers since 1991 has been extended to a more versatile range of UL-listed fire-protective and impact-safety 45-minute applications

The expanded product, PYROSWISS 45, meets UL 9, 10B, 10C; CAN/ULC S104, S106; and NFPA 80, 252 and 257 fire-rated standards and ANSI Z97.1, CPSC16 CFR 1201-CATII, CAN/CGSB-12.1-M90 impact safety ratings. Expanding tint-free PYROSWISS from 20 minutes to 45 using our original process to create highly tempered safety glass while passing the hose stream test demonstrates Vetrotech’s commitment to not compromising between safety and fire-ratings, let alone safety and aesthetics that rival traditional glass. 

There are no UV-sensitive interlayers, no films or embedded wires in PYROSWISS 45, allowing the glass to realize a 90% visible light transmission in its low-iron option. Sound transmission values are among the lowest for its size on the fire-protective market today, with the added benefit of UV stability. 

“PYROSWISS was our first fire-protective product,” said Kevin Norcross, general manager of Vetrotech Saint-Gobain’s North American facility in Auburn, Washington. “This update expands on that original listing while providing the modern, ‘no-compromises’ approach that Vetrotech has become known for. Our customers will value the imperceptible protection of PYROSWISS 45 as much as its close match to non-fire-rated building glass.” 

In addition, PYROSWISS 45: 

  • Can be used in 45-minute rated openings including windows, doors, sidelites and transoms. 
  • Is suitable for hollow-metal framing and doors (3/4 inch glass thickness with minimum stop height of 5/8 inches). 
  • Is fully sourced and manufactured in North America for greater sustainability benefits.
