The Importance of Bird-Safe Glass in Exteriors: The Case of The Helios School
Glass has become a central element in modern architecture with the introduction of new strategies for designing and experiencing buildings. Its transparency and material composition allow for natural light to enter, while creating seamless connections between interior and exterior spaces. However, the prevalence of this material has meant that every year, billions of birds collide into glass structures.
These collisions tend to occur during the migratory pathways of birds, as they fly through cities and are drawn to internal lights in buildings or misjudge outdoor reflections of trees and vegetation, causing a huge number of bird deaths and injuries. In response to this challenge, an increasing number of cities are now introducing legislation that requires new construction to feature bird-friendly glass. Without compromising on the aesthetic appeal of glass, Eastman has developed Saflex™ FlySafe™ 3D Polyvinyl Butyral (PVB) interlayers. This additional layer features a three-dimensional reflective pattern that is highly visible to the bird’s eye from the outside while remaining subtle to the human eye from the inside. Delving into the application of this solution within architectural design, we showcase how The Helios School adopted this strategy.
