Birds do not see building elements, such as window frames, as visual markers to identify glass as a physical barrier. Instead, birds see a clear line of sight to what is on the other side of the glass, or an uninterrupted reflected image of natural surroundings on the glass surface. As a result, birds perceive an unobstructed flight path to vegetation or open skies leading to collisions with windows.
To create a more bird-friendly environment, NSG Group is excited to introduce Pilkington AviSafe™. By combining glass coating innovation with an understanding of bird vision, we have developed an award-winning solution that is proven to save lives.
How it works
Unlike humans, birds can see light in the ultraviolet spectrum. Pilkington AviSafe™ uses a unique patterned UV enhanced coating that disrupts the reflections, providing a visible marker to birds and preventing collisions. The technologically advanced patterned coating on Pilkington AviSafe™ uses the industry accepted 2x4 rule making the glass more visible to birds while remaining aesthetically appealing on both the interior and exterior surfaces.
Pilkington AviSafe™ has been tested by the American Bird Conservancy (ABC) and provides a threat factor of 12 when used in surface 1 application. When installed on surface #1 i.e. the external face of the window, the product is most effective in disrupting the reflection and deterring potential collisions.
