Advantages of Schott’s Pyran® S Glass:
- With a thickness of 6 mm, it can achieve fire resistance ratings between E30 and E120 minutes, depending on the panel size.
- Lightweight monolithic glass (even lighter than float glass)
- Suitable for outdoor use, without limitations related to UV radiation or temperature fluctuations
- Easy to use in architectural projects with high requirements, available in large sheets up to 2100 mm x 3200 mm, smooth, for unobstructed visibility
- The chemical composition prevents the formation of NiS crystals, eliminating the risk of spontaneous breakage. Therefore, Pyran® S glass does not require the Heat-Soak Test (HST).
PYRAN® S glass can be:
- Laminated with other types of glass (e.g., tempered, body-tinted)
- Incorporated into IGUs (insulating glass units) for energy efficiency
- Installed with standard fire-resistant frames, depending on certification
Fire-resistant glazing is always a system solution! Therefore, besides the glass itself, all other components of the assembly must also be fire-resistant (frame, silicone, proper installation).
The indicators E30, E60, E90, E120 are European classifications of the fire resistance of construction elements (including fire-resistant glazing), established according to standard EN 13501-2.
- E = Fire integrity (Integrity): The element prevents the passage of flames, hot gases, and flammable smoke into adjacent spaces for a certain period of time.
- The number (30, 60, 90, 120) = duration in minutes: The time during which the tested element maintains its fire integrity properties.
Architectural applications of PYRAN® S:
- Fire-resistant partitions
- Fire-rated doors and glazing
- Fire-rated façades and windows (exterior and interior)
- Glazing for escape routes and elevators
- Sills, skylights, floors, fixed panels
