Guardian® Bird1st™ UV Glass

Guardian® Bird1st™ UV is the latest advancement from Guardian Glass, a bird safe UV glass built to meet building requirements while protecting clean, unobstructed views. With jumbo sheet sizes and non-directional patterning, it can help lower installation costs (vs. our first-generation product).

While many alternative UV deterrents reflect about 30% of UV light, this Bird1st UV bird glass pattern reflects upwards of 75%, creating a signal to birds with an as-strong-as-possible chance of being seen. Boosting the contrast further, this requires use of a laminated outboard glass to absorb >99% of UV light outside the pattern. The result? A glass that provides a deterrent with a low level of visibility to humans, while earning a Threat Factor score of ≤25 from the American Bird Conservancy. 

*The American Bird Conservancy defines “bird-friendly” materials as those with a Threat Factor score of ≤30.
