Researchers estimate that hundreds of millions of birds are killed each year due to collisions with glass windows. To reduce bird-window collisions, Arnold Glas looked to Orb weaver spiders who build their webs with ultraviolet (UV) silk. The reflective properties of the UV threads protects the web by alerting birds to its presence. Birds fly around the web and do not destroy it. The ORNILUX® Bird Protection Glass has a UV-reflective coating that mimics the ultraviolet thread patterns found in Orb spider webs. Though the UV reflections are not visible to us, birds see the window as a web and are deterred from flying into it.
