Design and variety of PYRAN® S

PYRAN® S - Anti-reflective glazing
PYRAN® S for anti-reflective glazing performs several important functions all at the same time. It offers clear visibility due to low residual reflection and up to 2 hours of additional protection in case of fire. Anti-reflective coated PYRAN® S is a monolithic, thermally toughened borosilicate glass that is anti-reflective on both sides due to the fact that it is manufactured using a dip-coating process. The glass is coated with a hard, weather-resistant and multi-layered interference system. As a result, light reflection of 8% with an uncoated glass can be reduced to 1% using coated borosilicate glass.

PYRAN® S - Butt joint system
Butt joint PYRAN® S can be used very easily in demanding architectural designs. With the PYRAN® S butt joint system, for instance, a special silicone joint is used to join the panes of glass together without a frame. This helps create light, smooth sheets of glass that are virtually endless, and guarantees a clear view at all times without any disturbing vertical profiles. Simply ideal for applications in which fire protection needs to be combined with maximum visibility and minimal visual disturbances.

PYRAN® S - Structural glazing
Systems that use PYRAN® S for structural glazing require no frame constructions whatsoever. This is the result of a perfect symbiosis between 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, yet light, supporting structure. The panes remain permanently fixed in place, free of tension and without slippage under even the most extreme conditions, such as loads created by internal wind pressure or suction.

PYRAN® S – Composite safety glass
PYRAN® S composite safety glass as a laminate made of PYRAN® S and soda lime or single-pane safety glass can be used to meet special requirements for noise protection and protection against falls.
The use according to TRLV and TRAV is stipulated in the general type approval Z-70.3-145. In addition to certification of protection against falling, there are general type approval test certificates according to TRAV with timber or steel frames.
