Risk-free glass surfaces with 4BIRD® Etch
Each year, more than 1 billion birds die as a result of collisions with glass surfaces, with reflection and transparency being the main issues. Birds perceive reflections of the sky and surrounding environment as safe spaces, leading to tragic fatalities. Reflection creates the illusion of a natural habitat, while transparency prevents them from recognizing obstacles—especially dangerous in the case of corner glazing, glass bridges, and large glass facades. How can we effectively address this problem?
How Does 4BIRD®Etch Protect Birds While Preserving Architectural Beauty?
With advancements in technology and a growing focus on biodiversity conservation, innovative solutions are being developed to prevent birds from colliding with glass. While traditional stickers or patterns on glass remain common, modern architectural projects often demand more aesthetic and integrated solutions.
One such product is 4BIRD®Etch, which utilizes etched patterns on the glass surface. These patterns are nearly invisible to the human eye but serve as a clear obstacle signal for birds. Glass with these etchings significantly reduces the risk of bird collisions while maintaining a clean and contemporary architectural appearance.
However, bird protection is not the only advantage of this technology. The glass also offers a high level of energy efficiency. The COOL-LITE® coatings, integrated into this system, provide solar protection, optimal thermal insulation, and improved comfort for building occupants. With low reflectivity and color neutrality, buildings retain a modern and elegant look while also contributing to environmental conservation.
Modern architecture blends aesthetics, functionality, and ecological responsibility. Thanks to 4BIRD®Etch, it is possible to create a safe environment for birds while preserving energy-efficient glass solutions that meet the demands of contemporary architectural design.
