Project Description
GlasPro Bird Safe Glass Line
The Bird Safe Glass Line by GlasPro consists of a range of highly-effective Bird Safe solutions, satisfying the varying construction specifications for bird-friendly architectural glass. Bird Safe family of products includes ultraviolet reflective, acid-etched, and frit pattern glass. All of GlasPro’s Bird Safe solutions meet the industry-standard *2 x 4 rule for preventing bird collisions and strict requirements for safety, energy efficiency, and sustainability.
“The wide variety of native birds that thrive in urban areas underscores the importance of these artificial habitats to the survival of many bird populations. Creating green-space in urban environments, landscaping with native plants in backyards and parks, adopting architecture and lighting systems that reduce collisions, and keeping pets indoors will provide the greatest benefit to breeding birds and migrants seeking safe places to rest and find food during their spectacular journeys.”
– 2009 State of The Birds Report by the United States Government US Department of Interior

Ultraviolet Reflective Pattern
For architectural projects requiring a highly-transparent glass, the Ultraviolet Reflective Pattern is an ideal choice. This pattern is only visible to birds yet highly transparent to the human eye, enhancing the human visual experience. This glass has an American Bird Conservancy (ABC) Avoidance Index of 79%, which exceeds the ABC’s minimum standard for effective collision deterrent materials of 70%.

Acid-Etched Pattern
If your building project would benefit from eye-catching patterns on its exterior, Acid-Etched Pattern will give your building the distinctive look you desire. Walker AviProtek® glass is designed with acid-etched line or dot patterns located on the outside, (1st) surface which are visible to birds and help avoid collisions.

Frit Pattern
Require a Bird Safe glass that’s also energy efficient? GlasPro Bird Safe with fritted line or dot patterns silk-screened on the (1st) surface is an effective collision deterrent and helps to reduce the transmission of light and heat. Frit pattern has the added benefit of providing an attractive design detail on windows.
There is more than one way to create a bird-friendly building
The human visual experience specified for the building is a big factor in selecting a bird-friendly glass solution. The transparency of Bird Safe glass decreases with the increase in line or dot patterns visible to people – an important item to note. To help you better understand the product line of Bird Safe glass, we’ve created a chart to clearly explain the key features.

* The 2×4 rule describes the distance between elements making up a pattern applied to windows for the purpose of preventing bird strikes. To be effective, the pattern must uniformly cover the entire window and consist of elements of any shape (lines, dots, other geometric figures, etc.) separated by no more than 5 cm (2 inches) if oriented in horizontal rows, or by 10 cm (4 inches) if oriented in vertical columns. These patterns eliminate bird-window collisions when applied to the outer surface (Surface #1) of reflective panes, or when applied to any surface of multi-pane see-through windows. Greater spacing between pattern elements increases the risk of a strike and casualties.
