Product or processORNILUX is an insulated glass sheeting made by Arnold Glas, a Germany-based company, which is designed to reduce the causes of bird collisions. It uses a special ultraviolet (UV)-reflective coating that appears almost transparent to humans, but is clearly visible to birds, because they can see a broader UV spectrum than humans (see photos in gallery for bird's and human's view of the windows).
ORNILUX is now made in the USA by Glasswerks, Inc.

Challenges solvedMore than 250,000 birds per day in Europe die from collisions with glass windows, and estimates in the United States run into the hundreds of millions. Birds either don't see the glass or they see reflections in the glass, such as trees, that make them try to fly through as if it isn't there.
This is a problem world-wide due to the prevalence of glass windows for homes and buildings, and the problem is getting worse. Due to Green Building Practices that focus mostly on energy efficiency, many architects are incorporating larger and larger expanses of glass to let in natural light to save energy. Additionally, the biggest challenge is that people enjoy the aesthetics of glass; this will not change. ORNILUX offers a clear glass solution to allow the aesthetics we enjoy but the protection the birds require.
