Guardian Bird1st glass offers a balance of solar performance, aesthetics and bird safety. A UV stripe coating on the first surface is virtually invisible to the human eye in dry conditions and visually signals an impending barrier to birds and helps prevent collisions. Views remain clear, unlike traditional ceramic frit solutions, all while helping protect birds. Paired with select Guardian SunGuard low-emissivity coatings, Bird1st glass meets LEED Pilot Credit 55.
