Standard insulating glass has a relatively low thermal shock resistance. In the event of a fire, it breaks and there is a risk of the flames spreading to adjacent parts of the building.
The fire protection insulating glass "Pyrobel 16 IGU" from AGC Glass Europe prevents this over a period of 60 minutes. In daily operation, it offers all the comforts of normal insulating glass - plenty of daylight thanks to high transparency and colour neutrality, contemporary thermal insulation and, if required, effective sun shading, sound insulation and high security. It also has the "Cradle to Cradle Silver" environmental certification.
Wide range of fire-resistant glass products
With Pyrobel, AGC Glass Europe offers a wide range of fire-resistant glazing that can be combined as cut-to-size laminated glass and as custom-made, toughened fire-resistant insulating glazing with thermal insulation, solar control, sound insulation and safety properties.
In the event of fire, Pyrobel limits damage to the building, protects escape routes, facilitates access for rescue services and maintains the stability of important structural elements - intervention time is significantly extended. In its technical construction, Pyrobel is a laminated glazing that has foam-forming interlayers in the space between the panes, but these are invisible in normal operation.

In the event of fire, the interlayers react and form a stable, opaque barrier that prevents the spread of fire and at the same time considerably reduces heat transmission - the temperature on the pane surface facing away from the flames remains low.
How is the Pyrobel 16 IGU fire protection insulating glass constructed?
The Pyrobel 16 IGU product variant is frequently used in facades worldwide because it offers reliable protection on both sides of the glazing, is relatively slim and, with a Ug value of 1.1 W/(m2K), has contemporary insulation.
In the insulating glass structure, there is a 6 mm thick pane, 15 mm SZR with argon filling and an iplus 1.1 thermal insulation coating on the room side, and the "fire protection package" on the outside of the façade: 3 mm glass, 0.76 mm PVB film, 3 mm glass, 1.5 mm interlayer, 8 mm glass, 1.5 mm interlayer, 3 mm glass.

The product thus achieves reliable room sealing against fire and smoke and thermal insulation up to class EI30, protection against radiation up to class EW60 and high impact resistance in accordance with EN 12600. The particularly colour-neutral glazing is fire-resistant on both sides in accordance with EN 13501-2 and has been successfully tested in many common facade systems.
What other technical properties does Pyrobel 16 IGU offer?
Despite the fire-resistant design, a remarkable 73 per cent of daylight enters the room. The high sound insulation value of Rw = 42 dB protects against traffic noise and thus ensures quiet rooms. The g-value can be optionally reduced from 58 per cent to 28 per cent with an additional Stopray solar control coating. The product offers high penetration resistance (up to class P8B) and bullet resistance (up to class BR5-NS). The maximum size of Pyrobel 16 EG is 1400 x 2800 mm, the toughened version Pyrobel T is actually available up to 2000 x 4500 mm.

All fire-resistant glazing from AGC has been awarded the Cradle to Cradle Silver certificate, which makes it easier for architects and planners to certify buildings according to environmental standards such as Leed and Breeam.
