Bird-friendly Interlayer: Saflex® FlySafe™ 3D by Eastman

The new PVB interlayer is an effective way to keep birds from colliding with glass facades without compromising on views.

Bird-friendly Interlayer by EastmanToo often, birds fail to see glass, or misjudge reflections — all leading to avoidable collisions. Eastman, in partnership with SEEN AG, has introduced a new polyvinyl butyral (PVB) bird-friendly interlayer for laminated glass: Saflex FlySafe 3D, a solution to avoid bird collisions without compromising on the view or beauty of glass facades.

Unlike other bird-protection approaches that use decals, printing, or etching on the surface of the glass, Saflex FlySafe 3D features three-dimensional, reflective sequins between two layers of glass. The sequins catch the light at different angles, subtly twinkling to deter birds from the glass — something two-dimensional dots and stripes don’t do.

Due to the 3D nature of the sequins, less coverage is required. The discreet sequin pattern covers less than 1% of the glass area. Other solutions considered highly effective have at least five times the coverage and can be greater than 25%. And because the sequins are layered between glass, it is a long-lasting bird-protection solution.

Collision Laboratories in Hohenau-Ringelsdorf, Austria, have tested and rated the 3D-reflective technology used in Saflex FlySafe 3D. In both transmission and reflective testing, it is recognized in the industry and by ornithologists as one of the best — classified as highly effective, durable, and with better aesthetics. Additionally, Saflex FlySafe 3D helps builders and building owners meet emerging regulations and certifications for bird protection, including securing LEED SSpc55 pilot credits for bird collision deterrence thanks to a threat factor of less than 10 from the American Bird Conservancy.

The minimal coverage of the bird-deterring sequins makes Saflex FlySafe 3D interlayers ideal for a variety of applications, including atriums, balustrades, cladding, curtain walls, exterior doors, facades, link bridges, podium glass, skylights, and windows.

In addition to bird collision avoidance, Saflex FlySafe 3D interlayers can be combined with selective coatings and other Saflex products to enhance glass further, giving it greater security, stability, acoustic control, solar control and protection from harmful UV rays.
