PYRAN® 

At a glance

Superior safety glass

PYRAN® fire resistant glazing made of borosilicate is far superior to conventional safety glasses with a soda-lime composition:
  • High ability to withstand temperature differentials: Compared to other products, tempered borosilicate glass withstands temperature differentials much better and can thus be glazed with normal edge cover (15 ± 2 mm).
  • Higher softening temperature: Due to the fact that the glass is self-supporting for over 30 minutes, large panes and relatively basic frame constructions are now possible.
  • Higher viscosity: Due to the low flow behavior that results from the high viscosity of borosilicate glass, longer fire resistance times in excess of 90 minutes can be achieved with more edge cover.
  • No forming of NiS crystals: The chemical composition of borosilicate glass is such that NiS crystals are unable to form. This means a sudden fracture caused by embedded NiS crystals can be ruled out with PYRAN®.



Proven and safe

PYRAN® remains transparent, even under high thermal loads. This ensures vital insight in the case of a fire and makes it much easier to evacuate a burning building safely. Excellent color reproduction and high transmission in the visible and UV range ensure that this increase in security is not achieved at the expense of appearance. It is certainly no coincidence that PYRAN® has been proving itself in airports, hospitals, hotels, industrial buildings, museums, offices, schools, shopping centers, sports facilities and even on cruise ships for decades.

Areas of application

Doors

Whether fitted in timber or steel structures, SCHOTT Technical Glass Solutions in cooperation with system partners develop doors with PYRAN® which are excellently suited and approved for sale in markets outside of Germany*.

*The German building code does not list G (E) doors.

Façades

Fire protective glazing is used to prevent fire from spreading vertically and thus to protect neighboring structures from catching fire. ISO PYRAN® S is suitable for all application areas with multi-functional requirements. ISO PYRAN S provides shading as well as thermal and noise protection in conjunction with an original design. In cooperation with system partners, SCHOTT Technical Glass Solutions GmbH develops designs with PYRAN® that have received international approvals and are ideally suited for use in façades.

Roofs

Fire protective glazing is used in roofs whenever the goal is to prevent fire from spreading vertically. Because the glass in overhead areas is subject to particular loads, building codes require the use of laminated safety glass in accordance with the technical regulations. ISO PYRAN® S can be used in overhead applications in simple and light structures.

Partitions

Transparent fire-rated partitions provide protection in case of fire while at the same time allowing day light to flow freely from room to room. Landings to staircases are protected attractively yet effectively. The use of PYRAN® in skylights elegantly combines functionality with aesthetics to allow natural lighting in interiors.

Smoke Screens

PYRAN® is ideal for use in smoke screens in heavily frequented areas such as atria, shopping centers and underground train stations. Systems that use PYRAN® S-P do not need frame constructions at all. This is the result of a perfect symbiosis of glass panes connected to each other by joints that are barely noticeable and point mounts and brackets that secure the glass panes to a strong, but light, supporting structure.
