Guardian will exhibit its new Guardian Bird1st glass. The product provides a UV stripe coating on the first surface that is virtually invisible to the human eye in dry conditions, unlike ceramic frit solutions. The UV stripe coating helps to prevent collisions by visually signaling an impending barrier to birds. Many migratory birds see in the UV spectrum, while humans only see in the visible spectrum. Guardian Bird1st coated glass is tested effective by the American Bird Conservancy. Booth# 1121
