Around the world, billions of birds die as a result of collisions against windows and glazed facades, so much so that several countries have laws mandating the installation of bird-saving glazing for newly constructed buildings. In response to a global problem, Eastman, in partnership with Seen AG, has come up with a new polyvinyl butyral (PVB) interlayer for laminated glass: Saflex FlySafe 3D, which is effective in avoiding collisions without compromising the visibility or aesthetics of glass facades.
Three-dimensional glossy vignettes
Unlike other approaches to bird protection that use decals, printing or etching on the glass surface, Saflex FlySafe 3D uses three-dimensional glossy bubbles between two layers of glass. The glossy vignettes catch light from different angles, shining faintly to keep birds away from the glass. The 3D nature of the glossy vignettes allows for less coverage, while the discrete pattern of the glossy vignettes covers less than 1 percent of the glass surface. In addition, because the glossy vignettes are arranged in layers between the glass, it is a long-lasting solution.
A global problem
"Given the predominance of glass in modern architecture, bird collisions are a global problem," said Heather Singler, Eastman's Global Architecture Business Director. "Too often, birds fail to see glass and misjudge reflections, resulting in avoidable collisions. And we can effectively avoid such collisions. Saflex FlySafe 3D has proven effective as a deterrent."
Useful and beautiful
Collision Laboratories in Hohenau-Ringelsdorf, Austria, separately tested and evaluated the 3D reflective technology used in Saflex FlySafe 3D. In terms of transmission and reflection testing, it is recognized in the industry and by ornithologists as one of the highly effective, long-lasting and aesthetically pleasing rated products. In addition, Saflex FlySafe 3D enables builders and owners of glazed buildings to comply with regulations and certifications for bird protection, including obtaining LEED Sspc55 pilot credits for collision deterrence as the American Bird Conservancy has indicated a threat factor of less than 10.
Minimal coverage of deterrent light bubbles makes Saflex FlySafe 3D interlayers ideal for a variety of applications: atria, balustrades, cladding, buffer facades, exterior doors, facades, connecting decks, glass stages, skylights and windows. In addition to preventing birds from colliding, interlayers can be combined with selected coatings and other Saflex products to enhance glass, giving it greater safety, stability, acoustic control, solar control and protection from harmful UV rays.
