Bird Safe Glass
Bird Friendly Glass
With an etched pattern on side #1 and a low-e coating on side #2, Prel-AirSecur glass combines bird safety and energy efficiency. The etched pattern on the outside is more easily seen by birds while remaining discreet from the inside.
The pattern is permanent, it does not require any particular maintenance and does not fade with time. The low-e on side #2 of the glass is more effective at blocking solar heat gain while controlling heat loss in cold weather. Prel-AirSecur Bird Deterrent Glass can help earn LEED Credits for sustainable buildings.
Prel-AirSecur glass prevents bird collisions against windows. It is available in oversized size up to 5180 mm (204 in.) high. Therefore architects and designers no longer have to compromise between largely fenestrated buildings and bird protection.
- Uninterrupted view from floor to ceiling
- Maximizes natural lighting
- Increased user satisfaction
- Provides a contemporary look
Thickness: 6 mm (other thicknesses available upon request)
Substrate: clear, extra-clear (other substrates available upon request)
Heat treatment: heat-strengthened or tempered
Configuration: double or triple insulating glass units
Oversized insulating glass units are subject to increased stress due to dead and live loads. Implementing a project with oversized glass requires careful planning.

Threat factor 25 Threat factor 15
Threat factor (TF) attributed by the American Bird Conservancy. A TF30 or less is considered as a bird-friendly material. A TF30 corresponds to a reduction in collisions of at least 50% in real conditions.
