Laminated glass
Float or UltraClear™
Two panes bonded with an interlayer. If it breaks, the fragments stay stuck to the interlayer. Laminated glass is not just one product: the number of interlayers, their acoustic properties, their colour and any coatings decide whether it is about safety, quiet, design or protection from overheating.
| Designation | 3.3.2 means two 3 mm panes with two interlayers; 4.4.4 means two 4 mm panes with four interlayers |
| Thicknesses | 6 to 20 mm from stock |
| Interlayers | clear, opal/matt, tinted, acoustic |
Used for
balustrades, roofs, façades, fixed partitions, windows and doors, insulating glass units
Lami clear
3.3.2 and 4.4.2. Standard safety laminated glass for windows, doors, fixed partitions and insulating units. Blocks 99% of UV radiation.
Laminated glassAcoustic laminated glass
3.3.2 SR or 4.4.2 SR. An interlayer that dampens sound: LamiGlass Acoustic, SoundControl. In an insulating unit, up to Rw 45 dB double glazed and up to Rw 48 dB triple glazed.
How to reach 42 dBCoated laminated glass
Solar control coating on 3.3.2 for homes, SunGuard™ for façades. One pane for safety, quiet and summer.
Figures by make-upLaminated glass that birds can see
Bird1st™. The interlayer carries reflective 9 mm dots spaced 90 mm apart, so a bird sees a barrier rather than a clear way through. The glass remains safety laminated glass. For canopies, façades and large glazed areas.
Bird1st™How to read 4.4.2.
The first and second numbers are the pane thicknesses in millimetres. The last number is the number of interlayers, each 0.38 mm thick. SR stands for Sound Reduction: an acoustic interlayer that dampens sound.
The EN 356 class tells you how much impact the glass can withstand. For the A classes, a 4.11 kg steel ball is dropped on the glass three times: P1A from 1.5 m, P2A from 3 m, P3A from 6 m, P4A from 9 m, and P5A from 9 m nine times. Classes P6B to P8B are tested with axe blows.
| Thickness | EN 356 class | |
| 4.4.2 | 4 + 0.76 + 4 = 8.76 mm | P2A |
| 4.4.2 SR | 4 + 0.76 + 4 = 8.76 mm, acoustic interlayer | P2A |
| 4.4.4 | 4 + 1.52 + 4 = 9.52 mm | P4A |
PVB interlayer thickness 0.38 mm.
Glass balustrades
If it breaks, the glass stays on the interlayer and the balustrade holds.
