With Saflex FlySafe 3D, Eastman introduces a new PVB interlayer that is an effective way to keep birds from colliding with glass facades and also enables highly transparent pane structures. Here we show the details.
Tim Blank, a metalworker in construction technology, passed his journeyman's examination in February this year and achieved the best overall result among all trainees in this profession in Swabia. At the same time, seele received an award for the best training company.Billions of birds are killed worldwide when they collide with window panes and glass facades. Many cities and countries already mandate bird-proof glazing on new buildings.

As a solution, Eastman, in collaboration with Seen AG, has introduced a new polyvinyl butyral (PVB) interlayer for laminated glass: Saflex FlySafe 3D, a highly effective bird strike prevention solution that also allows for highly transparent pane assemblies.
What is behind the new bird protection product?
Unlike other bird protection concepts (such as stickers, prints or etchings on the glass surface), Saflex FlySafe 3D features three-dimensional reflective sequins between two layers of glass.
These sequins "catch" the light at different angles and reflect it to deter birds from the glass. This is not possible with two-dimensional dots and stripes.
The 3D function of the sequins also means that less coverage is required; the discrete sequin pattern only needs to cover less than 1 % of the glass surface to be effective, as the developers point out. This is significantly less than other solutions.
Since the sequins are in the Saflex FlySafe 3D film and this in turn is between the glass of the laminated glass unit, this is also a long-lasting bird protection solution.

"Bird strike is a global problem," explains Matthias Haller, Marketing Technical Service at Eastman. "Too often birds overlook window and façade glass, they misjudge the reflections, which then leads to avoidable collisions. Saflex FlySafe 3D has proven to be highly effective in preventing such collisions - read bird strikes."
Certified bird protection film
The collision laboratories in Hohenau-Ringelsdorf (A) have tested and evaluated the reflective 3D technology used in the Saflex FlySafe 3D film. In both transmission and reflection tests, it was recognised as one of the best in the industry and by ornithologists - rated as highly effective, durable and aesthetically pleasing.
In addition, Saflex FlySafe 3D helps builders and specifiers comply with new regulations and certifications for bird protection. This includes meeting LEED SSpc55 pilot credits for bird strike deterrence thanks to a threat factor of less than 10 from the American Bird Conservancy.

Where can FlySafe 3D be used?
The minimised coverage of the bird repellent sequins makes Saflex FlySafe 3D films ideal for use on facades, windows, skylights, atrium glass, exterior doors, balustrades, glass bridges and much more.
In addition to bird strike protection, Saflex FlySafe 3D films can be combined with selective coatings and other Saflex products to further optimise glass assemblies and achieve greater security , this includes sound and solar control as well as protection from harmful UV rays.
"Even if a municipality does not prescribe bird-friendly buildings, it still makes sense to equip a building with them, says Matthias Haller.
"We are happy to help specify the right type of interlayer/film or combination of them to achieve the desired security, structural and design requirements. This way, birds can be protected without compromising."
