PYROSWISS 45 is a highly tempered clear fire-resistant safety glass; recently extended to a more versatile range of UL-listed fire-protective and impact-safety 45-minute applications. It meets fire-rated standards and impact safety ratings. There are no UV-sensitive interlayers, no films or embedded wires, 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.
In addition, PYROSWISS 45 is suitable for hollow-metal framing and doors (3/4 inch glass thickness with minimum stop height of 5/8 inches) and is fully sourced and manufactured in North America for greater sustainability benefits.
